Description:
Description ARTIFICIAL FUR AND FABRICATION METHOD THEREOF Technical Field [1] The present invention relates generally to pile fabrics and, more particularly, to artificial fur fabricated with pile like natural fur and having improved durability capable of withstanding loss of pile. Background Art [2] In general, pile fabrics commercially applicable to artificial fur have been produced by a variety of methods in the art. One example is shown in FlG. 4, which is an enlarged view showing the structure of artificial fur fabricated according to a con¬ ventional method. As shown in FlG. 4, pieces of pile 2 are interlaced in the form of V- shape with the weft of a basic weaving texture 1, creating an interlacing part 4. This pattern of interlacing, namely, weaving, is repeated to constitute most of artificial fur. After weaving, the backside of the interlacing part 4 is coated with a back adhesive layer 6 so that the pieces of pile 2 cannot be separated from the weft of the basic weaving texture 1 due to friction or other unfavorable causes. Disclosure of Invention Technical Problem [3] However, such a conventional fabrication method and a resultant texture of artificial fur may have the following drawback. In conventional technique, adhesive coating is executed after the pieces of pile 2 are densely interlaced during weaving. So, when the back adhesive layer 6 is formed, coated adhesive cannot easily penetrate the inside of the interlacing part 4 and is applied to only the backside. Unfortunately, this may cause the decline in adhesive strength, and therefore, some pieces of pile 2 are often separated from the weft of the basic weaving texture 1. Consequently, this may be one of principal factors in reductions of pile durability and product reliability. [4] To solve such a problem, an attempt to fabricate more durable, reliable weaving texture has been made in this art. In this technique, a piece of pile is interlaced several times with the weft of the basic weaving texture, thus forming more complicate weaving texture. This conventional technique may, however, lower weaving efficiency and productivity. Technical Solution [5] It is an object of the present invention to provide an improved artificial fur having excellent durability and good reliability. [6] Another object of the present invention is to provide a method of fabricating an improved artificial fur having excellent durability and good reliability by enhancing adhesive strength between a basic weaving texture and a piece of pile and among pieces of pile. Description of Drawings [7] FlG. 1 is an enlarged view showing the structure of artificial fur in accordance with one exemplary embodiment of the present invention. [8] FlG. 2 is an enlarged view showing the structure of artificial fur in accordance with another exemplary embodiment of the present invention. [9] FlG. 3 is an enlarged view showing the structure of artificial fur in accordance with still another exemplary embodiment of the present invention. [10] FlG. 4 is an enlarged view showing the structure of artificial fur fabricated according to a conventional method. Best Mode [11] To attain the above and other objects, the present invention provides artificial fur that comprises an interlacing part having a basic weaving texture and pieces of pile interlaced with the basic weaving texture, and a front adhesive layer coated on the front side of the interlacing part so as to prevent loss of the pieces of the pile and thereby to enhance durability of the pieces of the pile. [12] The artificial fur of the present invention may further comprise an inner adhesive part formed in the interlacing part so as to improve adhesive strength between the basic weaving texture and the piece of pile and among the pieces of pile. [13] The artificial fur of this invention may further comprise a back adhesive layer coated on the backside of the interlacing part. [14] In addition, the present invention provides a method of fabricating artificial fur, the method comprising forming an interlacing part by interlacing pieces of pile with a basic weaving texture, and forming a front adhesive layer by coating adhesive on the front side of the interlacing part. [15] The method of the present invention may further comprise, before the forming of the interlacing part, preparing an aqueous solution including adhesive and antistatic agent, and forming an inner adhesive part formed in the interlacing part by mixing the pieces of pile with the aqueous solution. [16] In the method of this invention, the pieces of pile between eighty-two and ninety- nine weight percents may be mixed with the aqueous solution between one and eighteen weight percents. Preferably, the pieces of pile having ninety weight percent may be mixed with the aqueous solution having ten weight percent. [17] The method of this invention may further comprise forming a back adhesive layer by coating adhesive on the backside of the interlacing part before or after the forming of the front adhesive layer. [18] Exemplary, non-limiting embodiment of the present invention will now be described more fully hereinafter with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, the disclosed embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The principles and feature of this invention may be employed in varied and numerous embodiments without departing from the scope of the invention. [19] Structure of Artificial Fur [20] FIGS. 1 to 3 show respectively, in enlarged views, the structure of artificial fur in accordance with exemplary embodiments of the present invention. [21] Referring to FIGS. 1 to 3, each artificial fur according to the exemplary em¬ bodiments has a conventional, common configuration and process that pieces of pile 2 are interlaced with the weft of a basic weaving texture 1, creating an interlacing part 4. Moreover, the artificial fur of the embodiments is characterized in common by a front adhesive layer 3 coated on the front side of the interlacing part 4 where movable ends of the pile 2 are extended. The front adhesive layer 3 may enhance durability of pile pieces by preventing loss of pile 2. [22] Additionally, as shown in FIGS. 1 and 3, an inner adhesive part 5 may be formed in the interlacing part 4 when weaving is made between the basic weaving texture 1 and the pieces of pile 2 before forming of the front adhesive layer 3. The inner adhesive part 5 may further improve adhesion between the basic weaving texture 1 and the piece of pile 2 and among the pieces of pile 2. Also, as shown in FIGS. 2 and 3, a back adhesive layer 6 may be optionally coated on the backside of the interlacing part 4. [23] As discussed above, the artificial fur exemplarily shown in FIG. 1 has the inner adhesive part 5, together with the front adhesive layer 3. The artificial fur exemplarily shown in FIG. 2 has the back adhesive layer 6, together with the front adhesive layer 3. And the artificial fur exemplarily shown in FIG. 3 has the inner adhesive part 5 and the back adhesive layer 6, together with the front adhesive layer 3. [24] Fabrication Method of Artificial Fur [25] The above-described artificial fur, for example, having the structure shown in FIG. 3, is fabricated by means of the following method. [26] At the outset, an aqueous solution including adhesive, softener, and antistatic agent is prepared. The pieces of pile 2 are mixed with the aqueous solution such that the solution fully permeates into and coats the pieces of pile 2. Preferably, the aqueous solution between one and eighteen weight percents is mixed with the pieces of pile between eighty-two and ninety-nine weight percents. [27] After the above preparation for weaving is completed, the interlacing part 4 is formed through a weaving process that interlaces the pieces of pile 2 with the basic weaving texture 1. At this time, adhesive in the aqueous solution permeates into the in¬ terlacing part 4, so the inner adhesive part 5 is formed in the interlacing part 4. [28] After the weaving process, adhesive material is coated on the front side of the in¬ terlacing part 4. Herein, the front side means a side at which movable ends of the pile 2 are extended. By such coating of adhesive material, the front adhesive layer 3 is formed on the front side of the interlacing part 4. [29] This process for forming the front adhesive layer 3 may be performed by using a nozzle, preferably, a group of nozzles arranged in a width direction of the basic weaving texture 1. Adhesive material is directly applied to the front side of the in¬ terlacing part 4 through the nozzle so as to easily reach the front side. Preferably, while adhesive material is discharged to the entire width of the basic weaving texture 1, the basic weaving texture 1 interlaced with the pieces of pile 2 is conveyed in a length direction. It is further preferable to pass the coated adhesive material through a cure oven. [30] After the front adhesive layer 3 is formed, adhesive material is also coated on the backside of the interlacing part 4 to form the back adhesive layer 6. As discussed above, this process for forming the back adhesive layer 6 may be optionally performed. Also this process may be performed before forming the front adhesive layer 3. [31] Experimental Example 1 [32] Before weaving, the pieces of pile were coated with an aqueous solution having softener and antistatic agent by mixing a ten weight percent aqueous solution and a ninety weight percent pile pieces. After weaving, the back adhesive layer and the front adhesive layer were formed respectively by coating and curing adhesive material the respective sides of the interlacing part. [33] Experimental Example 2 [34] Before weaving, the pieces of pile were coated with an aqueous solution having adhesive and antistatic agent by mixing a one weight percent aqueous solution and a ninety-nine weight percent pile pieces. After weaving, the front adhesive layer was formed by coating and curing adhesive material on the front side of the interlacing part. [35] Experimental Example 3 [36] Before weaving, the pieces of pile were coated with an aqueous solution having adhesive and antistatic agent by mixing a five weight percent aqueous solution and a ninety-five weight percent pile pieces. After weaving, the back adhesive layer and the front adhesive layer were formed respectively by coating and curing adhesive material the respective sides of the interlacing part. [37] Experimental Example 4 [38] Before weaving, the pieces of pile were coated with an aqueous solution having adhesive and antistatic agent by mixing a ten weight percent aqueous solution and a ninety weight percent pile pieces. After weaving, the back adhesive layer and the front adhesive layer were formed respectively by coating and curing adhesive material the respective sides of the interlacing part. [39] Experimental Example 5 [40] Before weaving, the pieces of pile were coated with an aqueous solution having adhesive and antistatic agent by mixing an eighteen weight percent aqueous solution and an eighty-two weight percent pile pieces. After weaving, the front adhesive layer was formed by coating and curing adhesive material the front side of the interlacing part. [41] Experimental Example 6 [42] Before weaving, the pieces of pile were coated with an aqueous solution having adhesive and antistatic agent by mixing a twenty weight percent aqueous solution and an eighty weight percent pile pieces. After weaving, the back adhesive layer and the front adhesive layer were formed respectively by coating and curing adhesive material the respective sides of the interlacing part. [43] Comparative Example [44] Before weaving, the pieces of pile were coated with an aqueous solution having softener and antistatic agent by mixing a ten weight percent aqueous solution and a ninety weight percent pile pieces. After weaving, the back adhesive layer was formed by coating and curing adhesive material the backside of the interlacing part. [45] A pile durability test was carried out using seven samples obtained from the above experimental examples and comparative example. The pile durability test uses Ac¬ celerator Method (AATCC 93-1999, weight-reduction rate(%)). As the result of test, the weight reduction rates were obtained as follows: 5.0% in the experimental example 1, 4.8% in the experimental example 2, 4.5% in the experimental example 3, 4.0% in the experimental example 4, 4.1% in the experimental example 5, 3.6% in the ex¬ perimental example 6, and 13.8% in the comparative example. As listed above, all the experimental examples did not exceed 5.0% weight reduction rate, whereas there was a great difference in weight reduction rate between the experimental example and the comparison example. [46] In case of the experimental example 6, the pile durability was superior to other cases, but adhesive material was exposed in part on the surface of the pile. Since the exposed adhesive needs to be removed in an additional post-treatment process, the ex¬ perimental example 6 may be not cost-effective and not practicable. [47] As appreciated from the above experimental examples, the front adhesive layer may offer a great enhancement in pile durability. Additionally, when the inner adhesive part, formed by mixing the aqueous solution between one and eighteen weight percents and the pieces of pile between eighty-two and ninety-nine weight percents, is employed together with the front adhesive layer, adhesive strength and resultant pile durability may be further enhanced. [48] While this invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Industrial Applicability [49] Present invention provides an improved artificial fur having excellent durability and good reliability. [50] Present invention provides a method of fabricating an improved artificial fur having excellent durability and good reliability by enhancing adhesive strength between a basic weaving texture and a piece of pile and among pieces of pile.
