[1] The present invention relates to a method for manufacturing a high stretchable coated yarn with air pockets and a high stretchable coated yarn made by using the same, and to a method for manufacturing a high stretchable fabric by using a high stretchable coated yarn with air pockets and a high stretchable fabric made by using the same, wherein a high stretchable yarn with the air pockets is coated with a predetermined degree of tension and a coating layer of the coated yarn gets pressed out of shape by the restoring force generated from the high stretchable yarn with the air pockets, thereby producing the high stretchable coated yarn having a natural texture formed thereon, and wherein the coated yarns are woven with a predetermined degree of tension and thus, the woven weft and warp yarns are overlapped and twisted irregularly by the restoring force generated from the high stretchable yarn with the air pockets, thereby producing the high stretchable fabric having a natural texture formed thereon. Background Art

[2] Generally, a high stretchable fiber yarn with air pockets is formed by binding a plurality of fibers, while having a plurality of tangled portions formed like a knot therealong at predetermined intervals, thereby forming a plurality of air pockets into which air is naturally filled. FIG.1 shows a generally fiber yarn, and as shown, a general fiber yarn 10' is formed elongated linearly by twisting or binding a plurality of fibers or a single fiber, and FIG.2 shows a high stretchable fiber yarn 10 as used in the present invention, which is not formed elongated linearly, unlike the general fiber yarn of FIG.l. As shown in FIG.2, the high stretchable fiber yarn 10 with air pockets is formed by binding a plurality of fibers, while having a plurality of tangle portions Id formed therealong at predetermined intervals. As the tangle portions Id are formed, of course, the left and right sides of the yarn 10 are naturally swollen to form air pockets Ic. Thus, the high stretchable fiber yarn 10 has the air pockets into which air is filled naturally, thereby providing high warmth and humidity-keeping effects.

[3] Of course, the high stretchable fiber yarn 10 with the air pockets is a well known yarn having specific functionality, but there is no endeavor or suggestion for coating the high stretchable fiber yarn 10 with the air pockets and providing a fabric woven by the coated yarns.

Mode for the Invention

[37] The present invention relates to a method for manufacturing a high stretchable coated yarn. Therefore, the construction and operation of the present invention will be explained in detail with reference to FIGS.2 to 14. That is, the present invention have four categories, first of which is a method for manufacturing a high stretchable coated yarn with air pockets, second of which is a high stretchable coated yarn made by using the method for manufacturing a high stretchable coated yarn, third of which is a method for manufacturing a high stretchable fabric by using a high stretchable coated yarn with air pockets, and fourth of which is a high stretchable fabric made by using the method for manufacturing a high stretchable fabric. Therefore, the present invention will be described in the above-mentioned order.

[38] [Method for manufacturing high stretchable coated yarn]

[39] There is provided a method for manufacturing a high stretchable coated yarn with air pockets, including the steps of: drawing high stretchable fiber yarns 10 and positioning the high stretchable fiber yarns 10 to a yarn coating system; supplying the high stretchable fiber yarns 10 to the yarn coating system, while applying a predetermined degree of tension to the high stretchable fiber yarns 10; feeding a polymer-molten liquid to a casing 31 of the yarn coating system and coating the outer peripheries of the high stretchable fiber yarns 10 to a predetermined thickness; and hardening the coated yarns 12 to make the high stretchable coated yarn 12.

[40] In other words, a plurality of high stretchable fiber yarns 10 as produced previously is formed to a roll or bundle shape and is positioned at the yarn coating system. The yarn coating system is equipped with a plurality of machines for coating the outer peripheries of the high stretchable fiber yarns 10. Some of the machines are already known, and some of them are introduced by the same applicant as the present invention. The known parts and the introduced parts by the same applicant as the present invention are combined and adopted in the method for manufacturing a high stretchable coated yarn according to the present invention, thereby making a new high stretchable coated yarn 12. At the first step, first, the plurality of high stretchable fiber yarns 10 is positioned at the front of the yarn coating system, while being ready to be coated.

[41] At the next step, the high stretchable fiber yarns 10 are supplied to the yarn coating system, with the predetermined degree of tension. That is, the high stretchable high stretchable fiber yarns are supplied continuously at the same speed, while being pulled with the predetermined degree of tension, without having any dipping in the conventional practices. In the preferred embodiment of the present invention are provided two kinds of yarn coating systems. One of the yarn coating system is the 'yarn coating system' disclosed in Korean Utility Model Registration No.20-383281 as filed by the same applicant as in the present invention, and the other is a 'yarn color-coating system' as will be filed by the same applicant as in the present invention. In the preferred embodiment of the present invention, hereinafter, the former is referred to as first yarn coating system 100, and the latter is referred to as second yarn coating system. The high stretchable fiber yarn is coated in a state of being pulled with the predetermined degree of tension through the first and second yarn coating systems, which will be in detail described later. Since the high stretchable fiber yarn of the present invention has more excellent stretchability than natural yarns and general synthetic resin fiber yarns, it may be loose, moved, and swung if a little force is applied thereto. Thus, the high stretchable fiber yarn is coated in the state of being pulled with the pre- determined degree of tension. Especially, when the coated yarn 12 is made by pulling the high stretchable fiber yarn with the predetermined degree of tension, it is contracted later by the generation of a restoring force generated from the high stretchable fiber yarn 10, and thus, the coating layer (the polymer-molten liquid layer Ik) surrounding the outer periphery of the high stretchable fiber yarn is pressed out of shape and has an irregular shape and direction, thereby making the coated yarn 12 providing natural texture and feeling thereon, which is not found in the conventional coated yarn.

[42] At the third step, next, the polymer-molten liquid is fed to the casing 31 of the yarn coating system and is coated around the outer peripheries of the high stretchable fiber yarns 10. The polymer-molten liquid is a composition for coating having a flame- resistant material or a non-combustible material, so as to provide specific functionality to the coated yarn of the present invention. Alternatively, general synthetic resin is coated around the outer periphery of the high stretchable fiber yarn. In the preferred embodiment of the present invention, by the way, the high stretchable fiber yarn 10 is coated via the first yarn coating system or via the first and second yarn coating systems at the same time. When it is passed through only the first coating system, the high stretchable fiber yarn 10 is coated with one color, but when it is passed through the second yarn coating system, the high stretchable fiber yarn 10 becomes the coated yarn having a variety of sectional shapes and multiple color tones.

[43] At the fourth step, finally, the coated yarns 12 are hardened to produce high stretchable coated yarns. That is, the polymer-molten liquid is coated around the outer periphery of each high stretchable fiber yarn 10 and is then hardened, thereby finishing the manufacturing process for the coated yarn 12. The coated yarn 12 may be subjected to two types of hardening, that is, water-cooling and air-cooling. The water cooling is divided into two types, first of which is carried out by allowing the coated yarn 12 to be passed through a tank in which cooling water is contained, and second of which is carried out by injecting cooling water from a nozzle to the coated yarn 12. The air- cooling is carried out by cooling the coated yarn 12 in the air. Therefore, the coated yarn 12 is produced through the cooling process.

[44] At the second step of the method according to the present invention, the predetermined degree of tension will be in detail explained. Preferably, the predetermined degree of tension is applied such that each of the high stretchable fiber yarns 10 is not loose by its own weight when it is fed to the yarn coating system. The reason why it is difficult to clearly define the predetermined degree of tension is that there are various differences in the features of the high stretchable fiber yarn 10. Actually, the high stretchable fiber yarn 10 has various degrees of stretchability in accordance with the manufacturer and the working environments. Further, the predetermined degrees of tension are varied in accordance with the intended degrees of stretchability of the coated yarn by a producer. In other words, in case of the high stretchable fiber yarn having a very high degree of stretchability, it is pulled with a substantially high degree of tension such that when it is fed to the yarn coating system, it is not loose to prevent the inclination of the high stretchable fiber yarn to one side of the coating layer (the polymer-molten liquid layer Ik) during the coating process. Moreover, if the coated yarn is reduced in length by the restoring force of the high stretchable fiber yarn 10 after the coating has been finished, the coating layer surrounding the outer periphery of the high stretchable fiber yarn 10 is also pressed and bent, and in this case, the degree of pressing or bending is determined in accordance with the characteristics of the fabric or product to be made by the following process. If it is desired that the fabric or product is much pressed and bent to provide natural beauty, the high stretchable fiber yarn 10 is pulled with a high degree of tension, and contrarily, if it is desired the fabric or product is less pressed and bent, the high stretchable fiber yarn 10 is pulled with a low degree of tension.

[45] According to the present invention, generally, the tension is applied to provide a frictional force to the outer periphery of the high stretchable fiber yarn, and the degree of tension is determined upon the size of the frictional force applied to the outer periphery of the high stretchable fiber yarn. Therefore, the predetermined degree of tension is not determined in the present invention, but it is enough to such a size that the high stretchable fiber yarn is fed and coated smoothly to the yarn coating system, that is, the high stretchable fiber yarn is not loose by its own weight and is not moved by means of a little force or wind.

[46] According to the present invention, more particularly, the predetermined degree of tension at which the high stretchable fiber yarn is not loose by its own weight is needed by the following reasons. First, the present invention is to coat the high stretchable fiber yarn 10 having a high degree of stretchability, and since the high stretchable fiber yarn is highly stretchable, a predetermined degree of tension should be constantly and continuously applied so as to conduct the coating operation.

[47] Secondly, the predetermined degree of tension has a most adequate size when the high stretchable fiber yarn is fed to the first and second yarn coating systems. The predetermined degree of tension at which the high stretchable fiber yarn is not loose by its own weight is an optimal tension when it is combined in the first and second yarn coating systems.

[48] An explanation on the yarn coating system applied in the present invention will be in detail described. Even though it is briefly described above, the yarn coating system according to the present invention adopts two kinds of coating. One kind of coating is carried out by coating the high stretchable fiber yarn with the polymer-molten liquid through the first yarn coating system, and the other kind of coating is carried out by coating the high stretchable fiber yarn with the polymer-molten liquid through the second yarn coating system to which the first coating system is combined, thereby producing the coated yarn having the multiple color tones. In case of the coating conducted by means of the first yarn coating system, the coated yarn has a single color, but in case of the coating conducted by means of the second yarn coating system to which the first yarn coating system is combined, the coated yarn advantageously has the multiple color tones.

[49] Based upon the above-mentioned order, the method for coating the high stretchable fiber yarn by means of the first yarn coating system will be first described, and next, the method for coating it by means of the second yarn coating system to which the first yarn coating system is combined will be described.

[50] As shown in FIGS.3 to 6, there is provided the first yarn coating system 100 having an extruding unit adapted to extrude and coat the polymer-molten liquid to the outer periphery of the high stretchable fiber yarns 10 individually supplied continuously to the yarn coating system, and a cooling unit adapted to cool the polymer-molten liquid coated around the high stretchable fiber yarns 10, wherein the extruding unit includes: a block 60 having a large passageway 61 to which the extruded polymer- molten liquid is introduced and a plurality of small passageways 62 formed independent of the large passageway 61 so as to feed the polymer-molten liquid to the high stretchable fiber yarn 10; and a distribution unit 70 adapted to allow the large passageway 61 to communicate with the small passageways 62, such that the polymer-molten liquid introduced through the large passageway 61 is distributed and extruded in equal quantity to the small passageways 62, thereby coating the polymer-molten liquid to the outer peripheries of the high stretchable fiber yarns 10.

[51] An explanation on the operation of the first yarn coating system 100 will be given below. As shown in FIGS.3 to 6, each of four (up to twelve) yarns 10 is inserted into through-holes 361 and 331 of an extension member 36 and an insertion member 33 and a yarn insertion hole 332 of the insertion member 33, and it is housed in a nozzle hole 341 of each nozzle 34 in such a manner as to be passed through the center of the nozzle hole 341. In this state, if the first yarn coating system 100 is activated to supply the four yarns 10 at a predetermined speed, the yarns 10 are moved individually in one direction at the predetermined speed, and the polymer-molten liquid supplied from an extruding part 5 is extruded to the large passageway 61 of the block 60. Since the distribution unit 70 has a housing 73 having a plurality of introducing space portions 731 formed to communicate with the large passageway 61 of the block 60, the polymer- molten liquid is supplied to the introducing space portions 731. Like this, the polymer- molten liquid supplied to the introducing space portions 731 of the housing 73 is extruded to small passageways 62 of the block 60 as a motor 74 of the distribution unit 70 is operated, and the extruding process will be explained hereinafter. For example, the motor 74 of the distribution unit 70 is rotated clockwisely as shown by the arrow in FIG.6, and thus, a main gear 71 connected to the motor 74 is rotated clockwisely, such that a plurality of planetary gears 72 gear-coupled to the main gear 71 are rotated coun- terclockwisely. As the planetary gears 72 are rotated, the polymer-molten liquid supplied to the respective introducing space portions 731 is filled between the teeth of the planetary gears 72 and into a discharging space portion 733 defined by the inner periphery of the housing 73 and is rotated counterclockwisely, thereby being extruded to flow space portions 732 of the housing 73. Since the flow space portions 732 of the housing 73 communicate with the small passageways 62 of the block 60, the polymer- molten liquid supplied to the flow space portions 732 is extruded to the small passageways 62 of the block 60. Since the small passageways 62 of the block 60 each communicate with the through-hole 311 of the casing 31 and the communicating holes 321 of the insertion member 32 and the nozzle hole 341 of the nozzle 34 via the gap formed among the conical- shaped end portion of the insertion member 33, a fitting member 32 and the nozzle 34, the polymer-molten liquid supplied to the flow space portions 732 is extruded to the nozzle hole 341 of the nozzle 34 via the through-hole 311, the communicating holes 321 and the nozzle 34. The extruded polymer- molten liquid is coated around the outer periphery of each yarn 10. Since the yarns 10 are supplied continuously in one direction, at this time, the polymer-molten liquid is coated around the outer periphery of each yarn 10. Since the yarns 10 are supplied continuously in one direction. After that, the yarns 10 coated with the polymer-molten liquid are passed through a cooling unit 40 adopting water-cooling and are then solid. Next, they are wound up on a winder or drawing means (not shown).

[52] As described above, according to the first yarn coating system 100, the polymer- molten liquid is applied to the four yarns 10 at the same time, thereby greatly increasing the productivity of the coated yarns and reducing the coating cost for the yarns 10.

[53] If the main gear 71 and the planetary gears 72 of the distribution unit 70 are rotated at a predetermined speed, moreover, the polymer-molten liquid supplied to the small passageways 62 of the block 60 is continuously supplied in an equal quantity, thereby obtaining the coated yarns having equal qualities to each other. That is, the yarns 10 have the same coating thickness as each other and are uniformly coated in a lengthwise direction thereof. If the diameter of the nozzle hole 341 of each nozzle 34 is varied, the thickness of each coated yarn 12 is adjusted.

[54] On the other hand, in the above-mentioned first yarn coating system 100, the four high stretchable fiber yarns 10 are supplied and coated with the polymer- molten liquid along the outer peripheries thereof. However, six high stretchable fiber yarns 10 may be supplied individually and six planetary gears 72 of the distribution unit 70 are arranged along the circumferential direction of the main gear 71, thereby coating the six high stretchable fiber yarns 10 individually. Of course, twelve high stretchable fiber yarns may be coated.

[55] Next, the method for coating it by means of the second yarn coating system in which the first yarn coating system is combined will be described. That is, the second yarn coating system is formed by combining the first yarn coating system 100 thereto. A casing in the second yarn coating system is somewhat changed in shape from that in the first yarn coating system, and further, the nozzle part at the inside of the casing is somewhat changed. The varied parts are combined to the first yarn coating system 100. Now, an explanation on the construction of the second yarn coating system will be given with reference to FIGS.7 to 14.

[56] Especially, as shown in FIGS.7 to 14, the second yarn coating system according to the present invention includes: a casing 31 constituting a nozzle-assembling body 30a adapted to receive the polymer-molten liquid for coating supplied under equal pressure from the small passageways 62 formed in the block 60 by the rotary force of the motor 74; a multi-tone block 800 adapted to be coupled to the top surface of the casing 31 by means of bolts 801 and having a plurality of tournament distribution type passageways 817 formed at the inside thereof so as to move the polymer-molten liquid therealong; and a multi-tone polymer-molten liquid injector 900 adapted to inject the extruded polymer-molten liquid to a polymer-molten liquid supply hole 802 formed at one side of the multi-tone block 800. So as to be combined smoothly to the first yarn coating system 100, the casing, the nozzles disposed at the inside of the casing, and a nozzle support rod are somewhat changed in shapes.

[57] In more detail, the multi-tone block 800, which has the equal size to or similar size to the casing (which is somewhat changed in shape) 31 in the first yarn coating system, is coupled to the casing 31 by means of the bolts 801. The multi-tone block 80 has the plurality of passageways 817 corresponding to the number of the second nozzles 820 mounted in the casing 31, thereby supplying the polymer- molten liquid to the upper side of the casing 31. The multi-tone block 800 has the polymer-molten liquid supply hole 802 formed at the lateral surface thereof in such a manner as to communicate with the multi-tone polymer-molten liquid injector 900. The polymer-molten liquid is injected by means of the multi-tone polymer-molten liquid injector 900 to the supply hole 802 of the multi-tone block 800 under a controllable pressure, while the polymer- molten liquid is being supplied to the lower end outer surface of the yarn 10. At this time, the polymer-molten liquid injected from the polymer-molten liquid injector 900 has the different color and quantity from that supplied from the lower side of the casing 31 to the lower side outer surface of the yarn 10, thereby producing the coated yarn 12 having various colors and tones coated on the high stretchable fiber yarn 10.

[58] Next, an explanation on the detailed configuration and operation of the nozzle- assembling body 30a will be given. As shown in FIGS.7,8 and 14, the nozzle-assembling body 30a includes: the casing 31 having a plurality of through-holes 311a formed to pass through the inside thereof and a coupling part 899 having a stepped projection disposed along the front side periphery of each through-hole 311a; the second nozzle 820 having a nozzle hole 821 formed along the inner periphery of the coupling part 899 and a wedge-shaped through space portion 822 moldedly inserted thereinto; and a fixing member 830 coupled to the coupling part 899 of the casing 31 at the front surface of the second nozzle 820 so as to stably couple the casing 31 to the second nozzle 820. Further, the nozzle-assembling body 30a includes; a nozzle support rod 840 adapted to be inserted into each through-hole 31 Ia of the casing 31 in such a manner as to be spaced apart from the second nozzle 820 by a given distance, the nozzle support rod 840 having a communicating hole 841 formed at the inside thereof and a stop stepped protrusion 842 moldedly formed along the outer periphery of one side thereof; a first nozzle 850 insertedly coupled to the front surface portion of the nozzle support rod 840, having a through-hole 851 formed at the inside thereof in a ball pen-like shape entirely and adapted to be coupled to the second nozzle 820 in such a manner as to form a predetermined distance from the wedge-shaped through space portion 822 of the second nozzle 820; and a cylindrical pressurizing member 860 disposed at the rear surface of the nozzle support rod 840 so as to pressurize the stop stepped protrusion 842 by means of a screw 861. Under the above-mentioned configuration, the polymer-molten liquid introduced through the small passageways 62 of the block 60 and the multi-tone polymer-molten liquid supplied from the multi-tone block 800 are fed by a predetermined quantity between the outer periphery of the first nozzle 850 and the through space portion 822 of the second nozzle 820, thereby forming a coating layer having various color tones on the outer periphery of the high stretchable fiber yarn 10.

[59] In this case, the nozzle-assembling body 30a is of a block-like shape such that the high stretchable fiber yarn 10 is inserted and supplied as the coated yarn 12, and as shown in FIGS.11 and 12, the nozzle-assembling body 30a is a block-assembling body that produces four or six coated yarns 12 and further eight or twelve coated yarns 12.

[60] As shown in FIGS.7 and 8, since the casing 31 has the plurality of through-holes

311a adapted to insert the second nozzle 820 and the nozzle support rod 840 thereinto, the second nozzle 820, the nozzle support rod 840 and the first nozzle 850 are insertedly fit to each through-hole 311a. Of course, the block 60 having the small passageways 62 is disposed on the underside of the casing 31, such that the polymer- molten liquid is supplied through the small passageways 62. More particularly, the second nozzle 820 and the first nozzle 850 are insertedly fit to the inside of each through-hole 31 Ia at the rear side of the fixing member 830, and at this time, the through space portion 822 is formed between the second nozzle 820 and the first nozzle 850, in which the yarn 10 can be coated with a variety of multi-tones. In addition to the formation of the through space portion 822, of course, the nozzle support rod 840 has a main polymer-molten liquid injection groove 844 formed along the outer periphery of one side thereof, a plurality of communication holes 845 formed extended from the main polymer-molten liquid injection groove 844 toward the forward lengthwise direction of the nozzle support rod 840 in such a manner as to communicate with the main polymer-molten liquid injection groove 844, a multi-tone polymer-molten liquid injection groove 846 formed at the other side of the outer periphery thereof, and a multi-tone communicating hole 847 formed extended from the multi-tone polymer-molten liquid injection groove 846 toward the forward lengthwise direction of the nozzle support rod 640 in such a manner as to communicate with the multi-tone polymer-molten liquid injection groove 846, thereby co-existing the polymer-molten liquid and the multi-tone polymer-molten liquid having various colors. [61] Hereinafter, a sequential procedure of feeding and coating the high stretchable fiber yarns in the second yarn coating system (to which the first yarn coating system is combined) adopted in the present invention will be explained. As shown in FIGS.7 and 14, the high stretchable fiber yarn 10 is passed through the communicating hole 841 formed on the nozzle support rod 840 as a part of the nozzle-assembling body 30a, the through-hole 851 of the first nozzle 850 formed at the front side of the communicating hole 841 and the nozzle hole 821 formed at the front side of the through-hole 851, and it is thus drawn through separate drawing means (not shown). As shown, by the way, the communicating hole 841 formed on the nozzle support rod 840 has a relatively large diameter, and the through-hole 851 of the first nozzle 850 formed at the front side of the communicating hole 841 has a relatively small diameter, through which the yarn 10 is passed. The size of the nozzle hole 821 of the second nozzle 820 is larger than that of the through-hole 851 formed in the first nozzle 850. The polymer-molten liquid is fed along the outer periphery of the first nozzle 850, and also, the multi-tone polymer-molten liquid supplied from the multi-tone block 800 is fed along the outer periphery of the first nozzle 850, such that they are filled into the through space portion 822 defined between the first nozzle 850 and the second nozzle 820. When the filled multi-tone polymer-molten liquid and polymer-molten liquid are coated along the outer periphery of the yarn 10, the coated yarn 12 has a larger thickness than the yarn 10. Therefore, the size of the nozzle hole 821 of the second nozzle 820 is larger than that of the through-hole 851 formed in the first nozzle 850. The multi-tone polymer-molten liquid and the polymer-molten liquid used in the present invention have no difference from each other, but they have different colors from each other. Anyway, they have no difference between their physical properties.

[62] Next, a sequential procedure of feeding the polymer-molten liquid and the multi-tone polymer-molten liquid into the through space portion 822 will be explained. As mentioned in the first yarn coating system filed by the same applicant as in the present invention, the polymer-molten liquid is moved upwardly along the small passageways 62 of the block 60 by the rotating force of the motor 74 and enters the inside of the through-hole 31 Ia of the casing 31. Next, the nozzle support rod 840 is disposed inside the through-hole 311a, and since the polymer- molten liquid injection groove 844 is formed along the outer periphery of the nozzle support rod 840 just above the small passageways 62 of the block 60, the polymer-molten liquid enters the polymer-molten liquid injection groove 844. Of course, since the polymer-molten liquid injection groove 844 is formed along the outer periphery of the nozzle support rod 840, the polymer-molten liquid is fed through the communicating holes 845 extended from the side of the polymer-molten liquid injection groove 844 when it is filled into the polymer-molten liquid injection groove 844. As shown in FIGS.7, 8 and 14, the communicating holes 845 are formed to be passed through the polymer-molten liquid injection groove 844 in such a manner as to be extended horizontally to the front side of the nozzle support rod 840, that is, to the lengthwise direction of the nozzle support rod 840. The communicating holes 845 communicate with the through space portion 822 formed between the first nozzle 850 and the second nozzle 820, such that the polymer-molten liquid is instantly filled into the through space portion 822.

[63] By the way, it is very important in the second yarn coating system in the present invention that the multi-tone polymer-molten liquid is also fed from the passageways 817 of the multi-tone block 800. That is, the multi-tone polymer- molten liquid injection groove 846, which has a smaller size than the polymer-molten liquid injection groove 844, is formed at one side of the outer periphery of the nozzle support rod 840, to which the multi-tone polymer-molten liquid is fed. Also, the communicating hole 847 is formed to be passed through the multi-tone polymer-molten liquid injection groove 846 in such a manner as to be extended toward the lengthwise direction of the nozzle support rod 840. FIGS.7, 8 and 14 show the position and structure of the injection grooves 844 and 846 and the communicating holes 845 and 847, and as shown, the polymer-molten liquid injection groove 844 is large, having the plurality of communicating holes 845, while the multi-tone polymer-molten liquid injection groove 846 is small, having one communicating hole 847. Therefore, upon the coating of the high stretchable fiber yarn 10, the polymer- molten liquid having a main color is supplied through the block 60 at the lower end of the system, and the multi-tone polymer-molten liquid having the color and shape different from the main color is supplied through the passageways 817 of the multi-tone block 800 at the upper end of the system.

[64] Even though one communicating hole 847 is formed to pass through the multi-tone polymer-molten liquid injection groove 846, of course, the present invention is not limited thereto. That is, the multi-tone polymer-molten liquid injection groove 846 is extended to a predetermined length along the outer periphery of the nozzle support rod 840, thereby having two or three communicating holes 847 formed to be passed horizontally through the multi-tone polymer-molten liquid injection groove 846. This permits the colors of the polymer-molten liquid coated on one yarn 10 to be very various.

[65] According to the first yarn coating system, the polymer-molten liquid is fed under the equal pressure to the plurality of nozzles 620 in one block 60. According to the present invention, by the way, when the multi-tone polymer-molten liquid is fed to the inside of the multi-tone block 800, the feeding is difference from that in the first yarn coating system. That is, in the first yarn coating system the polymer-molten liquid is fed by means of the combination of the planetary gears 72, but in the second yarn coating system the multi-tone block 800 forms the tournament type passageways 817, thereby feeding the polymer-molten liquid under equal pressure conditions.

[66] As shown in FIGS.7 and 8 and FIGS.12 and 14, the multi-tone block 800 has two through twelve tournament distribution type passageways 817 selectively adopted to correspond with the number of the nozzle-assembling bodies 30a inserted thereinto. In this case, the tournament type passageways 817 providing the same pressure as each other are formed to pass through the inside of the multi-tone block 800, while maintaining the pressures generated from the ends thereof at the equal state through the combination of the distance and diameter to the supply hole 802 to which the multi- tone polymer-molten liquid is fed from the tournament distribution type passageways 817, such that the multi-tone polymer- molten liquid is discharged therefrom in equal quantities for the same period of time. That is, FIGS.12a to 12d show various examples of the tournament type passageways 817 formed inside the multi-tone block 800. As shown in FIG.12a, the initial passageway 817 is divided into two passageways 817, and next, each of the two passageways 817 is divided into two passageways 817, thereby forming the total four passageways 817, such that the four passageways 817 are formed inside the multi-tone block 800, thereby allowing the four first nozzles 820 to be mounted. As shown in FIG.12b, the two passageways 817 are formed from the supply hole 802 and each of them is divided into two passageways 817 again, thereby forming the four passageways 817. Next, in the state where the four passageways 817 are divided into two passageway parts, three passageways 817 are separated from each of the two passageway parts, thereby forming the total six passageways 817. Of course, in the same manner as the above, in the embodiments as shown in FIGS.12c and 12d eight to twelve passageways 817 are formed. As one of the main features of the formation of the passageways 817, the passageways 817 have the same diameter and distance as each other, so as to maintain the same pressure as each other. Therefore, the tournament type passageways 817 in the multi-tone block 800 are operated under the equal pressure to each other, thereby discharging the multi-tone polymer-molten liquid in equal quantities therefrom. According to the present invention, however, so as to adjust the quantity of the multi-tone polymer-molten liquid, a valve 990 is mounted separate at the end of the last passageway 817, as shown in FIGS.7 and 14. If the valve 990 is opened to a large extent, a relatively large quantity of multi-tone polymer- molten liquid is fed to the through space portion 822 between the second nozzle 820 and the first nozzle 850, and contrarily, if the valve 990 is opened to a small extent, a relatively small quantity of multi-tone polymer-molten liquid is fed to the through space portion 822, thereby producing the coated yarns having different color tones from each other.

[67] As shown in FIG.13, next, the nozzle hole 821 of the second nozzle 820 is desirably formed in dumbbell-like, heart-like, and multi-angular shapes, thereby producing the coated yarn 12 having a variety of sections. That is, the nozzle hole 821 of the second nozzle 820, which surrounds the high stretchable fiber yarn 10, has a variety of shapes, and further, the polymer-molten liquid and the multi-tone polymer-molten liquid are coated in different thicknesses around the outer surface of the high stretchable fiber yarn 10. Therefore, the coated yarn 12 has a variety of sections. FIG.13 shows the coated yarn 12 having a variety of sections, wherein a symbol C denotes the polymer- molten liquid and a symbol MC denotes the multi-tone polymer-molten liquid.

[68] As mentioned in the description on the first yarn coating system, the polymer-molten liquid is supplied along the small passageways 62 from the lower end of the block 60. In the second yarn coating system according to the present invention, however, the multi-tone polymer-molten liquid is also supplied from the multi-tone block 800 disposed at the upper side of the system. That is, the multi-tone polymer-molten liquid is supplied from the multi-tone polymer-molten liquid injector 900 as shown in FIGS.10 and 11. In more detail, the configuration and operation of the multi-tone polymer-molten liquid injector 900 will be explained.

[69] The multi-tone polymer- molten liquid injector 900 includes: a guide pipe 911 disposed along the top end periphery of a support rod 910 having multiple stages in such a manner as to be movable upwardly and downwardly; an operating frame 920 coupled to the guide pipe 911 so as to provide a frame for operation in a vertical direction; and a rotary motor 921, a decelerator 922 and a connecting member 923 coupled to one side of the operating frame 920. Further, the multi-tone polymer-molten liquid injector 900 includes: a hopper 930 coupled to the upper side of the operating frame 920 so as to house multi-tone polymer chips (which may be fed in liquid) thereinto; a communicating pipe 940 extended from the lower end of the hopper 930 in a horizontal direction; and a plurality of heaters 950 emitting a high temperature mounted inside the communicating pipe 940. Under the above-mentioned configuration, the multi-tone polymer chips are molten by the heating of the heaters 950 and the multi-tone polymer-molten liquid is supplied to a polymer-molten liquid supply hole 802 formed at one side of the multi-tone block 800 through an injector hole 941 formed at the end of the communicating pipe 940. The shaft of the decelerator 922 disposed at the inside of the communicating pipe 940 is formed of a feed screw 947.

[70] That is, the guide pipe 911 coupled to the operating frame 920 is disposed along the uppermost end periphery of the support rod 910 having the multiple stages. Thus, the guide pipe 911 is movable upwardly and downwardly along the support rod 910. If it is desired to fix the guide pipe 911 at an appropriate position, of course, the guide pipe 911 can be at its fixed position by means of a stopper (not shown), and the upward and downward movements of the guide pipe 911 are needed when a distance to be moved is short. Further, the operating frame 920, which is in the state of being coupled to the rotary motor 921, the decelerator 922, the connecting member 923, the hopper 930 and the communicating pipe 940, is coupled to the guide pipe 911, such that if the guide pipe 911 is moved upwardly and downwardly, the operating frame 920 is moved together with the guide pipe 911. That is, the guide pipe 911 is appropriately adjusted such that the injector hole 941 of the multi-tone polymer-molten liquid injector 900 is accurately positioned at the supply hole 802 of the multi-tone block 800 and comes coupledly into close contact therewith. Next, the multi-tone polymer chips having a desired color are filled into the hopper 930. Thus, the multi-tone polymer chips within the hopper 930 pushedly enter the inside of the communicating pipe 940 and are molten by the operation of the plurality of heaters 950 emitting high temperatures. After the multi-tone polymer chips are molten, the rotary motor 921 is rotated and reduced at its rotating speed by means of the decelerator 922. At this state, the feed screw 947 as the shaft of the decelerator 922 is rotated to push the multi-tone polymer- molten liquid toward the injector hole 941. The multi-tone polymer-molten liquid pushed by the force of the feed screw 947 is pushed through the injector hole 941 toward the supply hole 802 formed in the multi-tone block 800, thereby conducting the coating for the yarn 10. Even though not shown, of course, a separate pump or the distribution unit 70 as suggested in the first yarn coating system is disposed between the multi-tone polymer-molten liquid injector 900 and the multi-tone block 800, so as to pressurize the multi-tone polymer-molten liquid more strongly.

[71] On the other hand, the connecting member 923 connects the shaft of the motor 921 and the shaft of the decelerator 922 by means of a pulley and a belt or by means of a gear and a chain so as to change the rotating direction of the motor 921. That is, in the manner of transmitting the rotary force of the motor 921 to the decelerator 922, the connection is conducted by the pulley and belt. Alternatively, it may be conducted by the gear and chain, which also has the same effects. Therefore, according to the present invention the connecting member 923 having various known structures is used to transmit the rotary force of the motor 921 to the decelerator 922.

[72] Also, the support rod 910 has a support plate 918 having a plurality of guide members 917 mounted at the underside thereof and guide rails 919 coupled to the lower end thereof so as to move the support rod 910 horizontally in left and right sides. As shown, the multi-tone polymer-molten liquid injector 900 is movable vertically and horizontally. The vertical movement of the multi-tone polymer-molten liquid injector 900 is needed when it is easily near the multi-tone block 800, and the horizontal movement thereof is needed when the distance between the injector 900 and the multi- tone block 800 is very long or short. This enables the yarn color-coating system according to the present invention to be fixedly mounted easily and further enables easy utilization in a working area.

[73] The multiple- stage support rod 910 has a chain and a gear engaged with each other at the inside thereof, thereby conducting the vertical movement by means of the rotation of the motor. Even though the chain and gear are not shown, in other words, they are engaged with each other at the inside of the support rod 910 and are connected to the motor 921, such that when the motor 921 is rotated, the multiple- stage support rod 910 is vertically contracted and expanded. The vertical movement of the multiple- stage support rod 910 is similar to the vertical movement of the guide pipe 911. However, the movement of the guide pipe 911 is carried out when the distance to be moved is short, and contrarily, the contraction and expansion of the multiple- stage support rod 910 are carried out when the distance to be moved is long. As mentioned above, of course, the vertical movement of the multiple support rod 910 is needed to allow the multi-tone polymer-molten liquid injector 900 to be easily near the multi-tone block 800.

[74] [High stretchable coated yarn with air pocket]

[75] The present invention relates to a high stretchable coated yarn made by using the high stretchable fiber yarn with air pockets. That is, the high stretchable coated yarn is made through the method for manufacturing the high stretchable coated yarn with air pockets as mentioned above.

[76] According to the present invention, there is provided a high stretchable coated yarn with air pockets wherein a high stretchable fiber yarn 10 with air pockets is embedded with a predetermined degree of tension at the inside of the coated yarn, and a polymer- molten liquid layer Ik is formed by coating a polymer-molten liquid around the outer periphery of the high stretchable fiber yarn 10 to a predetermined thickness, such that the polymer-molten liquid layer Ik is contracted by means of the contraction and expansion of the high stretchable fiber yarn 10 embedded with the predetermined degree of tension inside the coated yarn, thereby having an irregularly twisted shape. The high stretchable coated yarn 12 of the present invention is made by using the first yarn coating system 100 and the second yarn coating system (to which the first yarn coating system is combined), and the main feature of the high stretchable coated yarn has the irregularly twisted shape. General fiber yarns or coated yarns are formed elongated, having predetermined thickness and diameter and relatively low degrees of contraction and expansion. This remarkably appears on the coated yarn. According to the present invention, however, since the high stretchable fiber yarn 12 having the high degree of stretchability is embedded inside the coated yarn, it is possible to form the irregularly twisted shape of the coated yarn 12. When the high stretchable fiber yarn 10 is coated with the polymer-molten liquid, it is coated in the state of being pulled before the coating operation, and if the force of pulling the high stretchable fiber yarn 10 is removed after the coating, it is contracted in length by means of the restoring force thereof. As a result, the polymer-molten liquid layer Ik coated around the outer periphery of the high stretchable fiber yarn 10 is resistant to the contraction of the high stretchable fiber yarn 10 and is thus returned to its shape in such a manner as to be a little bent or twisted at unexpected portions thereof. The high stretchable fiber yarn 10 positioned inside the polymer-molten liquid layer Ik is contracted in length, while the polymer-molten liquid layer Ik formed around the outer periphery of the high stretchable fiber yarn 10 tries to maintain its shape, so that the coated yarn 12 has the irregularly twisted shape.

[77] This is intentionally provided in the present invention. According to the present invention, the coated yarn has natural beauty, which is not provided at all in the existing coating technology wherein the coated yarn has a left and right symmetrical layer to provide artificial beauty.

[78] [Method for manufacturing high stretchable fabric by using high stretchable coated yarn with air pocket]

[79] The present invention relates to a method for manufacturing a high stretchable fabric by using a high stretchable coated yarn with air pockets. That is, there is provided a method for manufacturing a high stretchable fabric with air pockets including the step of: weaving weft yarns and warp yarns by means of a weaving loom by using high stretchable coated yarns 12 with air pockets made by coating a polymer- molten liquid layer Ik having a predetermined thickness around the outer peripheries of high stretchable fiber yarns 10, while the high stretchable coated yarns 12 are being pulled with a predetermined degree of tension, thereby forming the high stretchable fabric. The coated yarn 12 made by using the high stretchable fiber yarn 10 with the air pockets also has a substantially high degree of stretchability by means of the high stretchable fiber yarn 10 with the air pockets embedded therein. This is not found in the general coated yarns, but this is found uniquely in the coated yarn according to the present invention. The present invention well utilizes the features of the high stretchable coated yarn made according to the present invention. In other words, upon weaving, the plurality of warp yarns are inserted into a heald in such a manner as to be arranged in series, while being pulled with a predetermined degree of tension. When the weft yarns are inserted between the warp yarns by using an air jet or a water jet, the weft yarns are interlaced with the warp yarns, while being pulled a little with the predetermined degree of tension. Thus, the weft yarns and the warp yarns are interlaced with each other, while being pulled with the predetermined degree of tension, thereby forming the fabric M, and after that, the weft yarns and the warp yarns made with the high stretchable coated yarns 12 become contracted and reduced in their own length. Therefore, the weft yarns and the warp yarns forming the fabric M of the present invention are irregularly interlaced with each other in a little pressed or overlapped shape like the fabric as shown in FIG.2, not being interlaced with each other in a uniform pattern like a general fabric as shown in FIG.l. This is one of very important features in the present invention. The fabric M formed by interlacing the weft yarns and the warp yarns has natural patterns like non- woven fabric or Hanji (Korean traditional paper).

[80] The fabric M has natural and unique beauty, without having any uniform pattern and shape. In case where functional clothing, blinders, and curtains are made by using the fabric M, an amount of light permeated through the fabric M is varied by parts of the fabric M, thereby providing an excellent visual effect, and hence, they can be used as more beautiful interior materials.

[81] According to the present invention, the predetermined degree of tension is applied such that the irregular pressing surfaces formed around the outer periphery of the polymer-molten liquid layer Ik are stretched by the stretchability of the high stretchable fiber yarn 10 with the air pockets. When the high stretchable coated yarns 12 are woven, they are pulled to such a tension that the regular interlaced shapes of the weft yarns and the warp yarns forming the fabric M are pressed irregularly after the weaving.

[82] After weaving, a process for fixing the shape of the fabric M is needed. In other words, the predetermined degree of tension is removed from the high stretchable fabric M after finishing the weaving of the high stretchable fabric M, and the high stretchable fabric M is heated to a temperature in a range between 120° and 180°. Then, the high stretchable fabric M is cooled and fixed to the shape of fabric. After the fabric M is made, it has a little twisted, overlapped or pressed partially, as shown in FIG.2, thereby providing a natural shape. By the way, if the twisted, overlapped or pressed shape of the fabric M is still maintained, the restoring force of the high stretchable coated yarn 12 is generated again in accordance with the application of an external force or the variation of humidity and temperature, such that the twisted, overlapped or pressed shape of the fabric M may be changed to another shape. Of course, the change in the shape of the fabric M causes some problems when the fabric M is made as a finished product. Especially, one of the problems is the change in size. Since the change in size makes the product useless, there is a need for the maintaining of the natural shape of the fabric M.

[83] According to the present invention, thus, the predetermined degree of tension is removed from the high stretchable fabric M after finishing the weaving of the high stretchable fabric M, and the high stretchable fabric M is heated to the temperature in a range between 120° and 180°. Then, the high stretchable fabric M is cooled and fixed to the natural shape of fabric. The fabric M of the present invention becomes a high quality of fabric that can always maintain the natural beauty.

[84] [High stretchable fabric made by using high stretchable coated yarn with air pocket]

[85] The present invention relates to a high stretchable fabric made by using the high stretchable coated yarn with air pockets. That is, there is provided a high stretchable fabric with air pockets wherein a high stretchable fiber yarn 10 with air pockets is embedded with a predetermined degree of tension at the inside of a high stretchable coated yarn 12, and a polymer-molten liquid layer Ik is formed by coating a polymer- molten liquid around the outer periphery of the high stretchable fiber yarn 10 to a predetermined thickness, thereby producing the high stretchable coated yarn with the air pockets, such that the high stretchable coated yarn 12 with the air pockets is used as the weft and warp yarns for making the high stretchable fabric M, thereby being woven horizontally and vertically, thereby allowing the high stretchable fabric M to maintain the irregularly horizontal and vertical-overlapped shape by means of the contraction and expansion of the high stretchable coated yarn 10.

[86] The high stretchable fabric M which is made by the method for manufacturing the high stretchable fabric M by using the high stretchable coated yarn 12 with the air pockets is claimed in the present invention. According to the structural characteristic of the fabric M, the fabric M is made by using the high stretchable coated yarn 12. The high stretchable coated yarn 12 is formed by pulling the high stretchable fiber yarn 10 with the air pockets with the predetermined degree of tension out of the polymer- molten liquid layer Ik formed along the outer periphery of the high stretchable fiber yarn 10. In this case, the coated yarn 12 is a little pressed, while having a predetermined degree of stretchability. Of course, the weft and warp coated yarns are interlaced with each other with the predetermined degree of tension, and after weaving, the fabric M has partially twisted and overlapped natural shapes, while not having the Baduk board- like patterns precisely formed horizontally and vertically on the fabric M. According to the present invention, the fabric M having natural beauty is produced. [87] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
