Description:
THE CUSHION MATERIAL

[TECHNICAL FIELD]

[0001]

The present invention, and chairs and sofas of the seat surface and backrest, quilt, cushion, mattress, on the cushion material suitable for materials such as mattresses.

BACKGROUND ART

[0002]

Conventionally, excellent on both sides of the insulation and breathability, as a lightweight quilt of material, duvet is being used. From being used to duvet is a feather and down (feathers) (feathers), what percentage of the general down without often is with luxury goods. Feather is as the material available at low cost, when the feathers only, or the ratio of the feathers are used is that more than 50% is called a duvet, which is distinct from the duvet.

[0003]

Since the general duvet has a high warmth, light and has been widely used as a quilt. In the softness of down, may be also used as a mattress material. On the other hand, feathers so stiff heavy compared to down, duvet encapsulating feathers are used in the mattress. However, if you were prepared mattress feather as inclusions, and hard and also pressure dispersion function is also low for comfort becomes worse. In yet duvet using a feather with curved blades axis, hear a rustling when you move the futon is generated, and also lacks softness.

[0004]

The mattress of material, in recent years, foamed synthetic resin such as polyurethane resin and polyolefin resin has been as for the memory foam mattresses. Such foamed synthetic resin foam mattress with, it is said to be effective in inhibiting blood flow and prevent bedsores because the body pressure is dispersed throughout. On the other hand, poor breathability, I also have the side that it is difficult to escape the heat emitted from the body while sleeping. In addition rug-like foamed synthetic resin mattress, since consuming often load due to specific sites at bedtime, was also such specific sites only problem is to deformation and fatigue is likely to occur prior to.

[0005]

In order to solve such drawbacks of the rug-like foamed synthetic resin, for example, Patent Document 1 , a foamed synthetic resin in the pieces, arranged a felt-like layer on the upper and lower sides of the core portion composed of the piece, more the felt cotton outer layer, wool, the sandwich laminate disposed a surface layer made of soft material feather like housed in the bag, bedding, etc. core material formed by quilted have been proposed. [0006]

If bedding with certainly bedding such core material as described in Patent Document 1, since the foamed synthetic resin pieces to each use to move in the bag, has excellent cushioning properties, fatigue and waist, etc. Dari recessed locally, there is no deformation such as both ends are warped upward, is breathable and also ensured.

[0007]

However, when it is packed simply to simply bag foamed synthetic resin piece, but deformation and permanent set in the bag in the movement of the piece specified portion only cannot be generated, on the other hand, pieces each other caused when the bag moves by friction, or to deformation of each small piece resulting in rapidly occurred.

[0008]

In the case of using a foamed synthetic resin pieces In addition, unlike the rug-like foamed synthetic resin, rugged feeling occurs during usage. Because complex configurations, such as a sandwich-like laminate disposed a surface layer made of a felt-like layer and a soft material like a contrivance Thus in Patent Document 1 is required which leads to cost. Further, in the case of the structure of Patent Document 1, a new problem of felt- like layer that was the rug shape so that deformation and permanent set occurs in a particular site also occurs.

[SUMMARY OF THE INVENTION]

[An object of the invention is to provide]

[0010]

In view of the above circumstances, in the present invention, by using a feather and the foamed synthetic resin pieces available at low cost, insulation and or breathability feather has, it is possible to take advantage of the characteristics of low resilience with foamed synthetic resin , rustling or sound generated while the feathers, and an object thereof is to provide a cushioning material capable of suppressing sag rapid foam plastic pieces.

[Means for solving the Problems]

[0011]

In the present invention, a bag-shaped cloth, and the most important features to be a cushion material which is enclosed by a feather and the foamed resin pieces and mixed state.

Effect of the Invention [0012]

According to the cushion material of the present invention, while maintaining a low resilience which is the nature of the foamable resin, and breathability by which was in pieces can be secured. Nor can occur is preceded by deformation and permanent set from a specific site. In addition it is possible to ensure also warmth of lightweight is the nature of feather to.

[0013]

Further, as the effect of a mixture of a foamable resin piece and feather, and that the foamable resin piece enters between the feather, with a sound that rustling when it is moved to a feather sole drawback is reduced as possible, effervescent or to rapid deformation and of rugged feeling and each piece that occurs when it is used alone of resin pieces are also suppressed.

[0014]

Feather originally a good material breathable, also foamable resin to ensure breathability to the pieces also does not inhibit breathability. In this scene for practical use, breathable is promoted because the air moves to turn over the degree, since waste or sweat is volatilized is always maintained in a dry state it is very hygienic.

[0015]

As a result of the duvet down high blending products is required, feather the material often becomes slightly excess. On the other hand, the foamable resin pieces generated as scrap during the manufacture of rugs shaped expandable resin. Therefore, at present feather, a normal production line both expandable resin strip is discarded. However, since the present invention to use ENTER to feed the material to be disposed of in such a conventional production line, without causing waste by reducing the material loss, manufacturing costs along with also help to protect the environment and the (variable costs) it can be suppressed.

[MODE FOR CARRYING OUT THE INVENTION]

[0017]

(Bag-like fabric)

As schematically shown in Figure 1 , a bag-shaped cloth 1 used in the present invention are intended to be sealed in a mixed state and Feather 2 and the foamed resin 3 therein. The fabric used for the bag-like fabric enclosure it can be used without particular as long as it does not or leak and can jump out outside limit, and is down-proof processing is used such as inter alia duvets down and the like can be used suitably proof fabric. Also may be a back coating on the fabric, as long as the enclosure does not or leak or jump out outward, it is possible to use the basis weight of the fabric without any particular limitation. The bag-like fabric can be a single structure with one-piece, may have a multiple structure by a plurality of fabric.

[0018]

(Feather)

Feather (feathers) used in the present invention can be used without particularly limited as long as it is a feather that is commonly used in the duvet and down duvet. Can also be used by a feather from waterfowl also a feather from also can also be used by a feather from the mature birds also a feather from the immature bird. The size of the feather also is not particularly limited, preferably has a 30mm ~ 60mm in length from the root to the tip.

[0019]

Also a generally down to the normal feather cannot be sorted is attached, there is no particular problem even if down is mixed in the present invention. However, when the large percentage of down from feathers, since it is contrary to the purpose of providing a high- performance cushioning material using low-cost materials which is the object of the present invention, in the case of a feather in the present invention, Feather more than 50% like in the reference that called duvet, relative to the total weight of feather and down, it is intended to mean that there are feathers more than 50%.

[0020]

(Expandable resin)

Foamable resin used in the present invention are those bubbles (cells) are a number distributed in a matrix resin. Not particularly as the type of resin limited, a polio Fe fins resins and polyurethane resins that are commonly used as a cushioning material. Among these polyurethane resins are preferably used.

[0021]

Foamable resin used in the present invention is not a rug-like, is a collection of pieces. Pieces of shape and size are not particularly limited, for example in the case of spherical or quadrilateral including elliptical long diameter or long side is preferably of about 20mm ~ 40mm. However, it can be used as the foamable resin pieces of the present invention is not limited to a spherical quadrilateral or, may be of polygonal such arbitrary shape and may be a cylindrical body.

[0022]

(Mixing ratio, relative length, etc.)

Feather and the foamed resin pieces, is encapsulated in the interior of the bag-like fabric, is mixed. Feather and foam pieces proportion as the foamable resin piece of the bag-shaped cloth: Feather = 55:45-70:30 it is preferably in the range. When departing from the this range, expandable resin pieces and Fe

Among the feather, features too small percentage of the material has inherent originally, for example was foaming resin pieces

Luo low resilience, not exhibited was insulation etc. is sufficiently when feather, there is a possibility that the synergistic effect of mixing these is reduced.

[0023]

The relative lengths of the foamed resin strip to feather length, when it is the length of the average value of the base of each of the feather to the tip and 1, each of the foamable resin pieces of the longest side is (polygon mean value for) or the longest diameter (if spherical) of is preferably 0.3 to 0.7. The relative length of the expandable resin is too short, it is easy to inhibit the ventilation will penetrate the feather. On the other hand, the relative lengths of the foaming resin is too long, it becomes easy to inhibit restoration of the feather is aside of the press feather. Note that in the above definition, in the case of the foamed resin pieces, for example, a cylindrical shape is intended to adopt whichever is longer diameter and tube length.

EXAMPLES

[0024]

Below, I will be described in more detail in the present invention embodiment.

(Example 1) As polyurethane resin, I was using the (stock) Nitori furniture Vietnam EPE made of urethane foam model number "M55". This was into small pieces using a Foam cutting grinding function of machine "ESF007-2" of Shenzhen Xinqunli Co. (China). I was to fit the length of the longest side of the pieces in the range of 20mm ~ 40mm respectively. Longest side average of pieces each is 30mm. As a Feather, I was using the "WASHED GRAY DUCK FEATHER 4cm-6cm" manufactured HANGZOU SAMSUNG DOWN PRODUCT CO., LTD. The average length of the base of each feather to the tip is 50mm.

[0025]

Above feather and the polyurethane resin pieces and the weight ratio 65:35 (Feather: polyurethane resin pieces) in down proof fabric (WUJIANG CITY XINCHUN TEXTILE Co., Ltd. (China))

Down Proof Fabric [75D/36Fxl60D/288F/C]) was encapsulated by mixing in a bag-like fabric. This was a cushion material of Example 1. The photograph showing the appearance of the cushion material used in Example 1 is shown in FIG.

[0026]

(Comparative Example 1)

Except that was sealed in a bag-shaped cloth is changed only in the feather was the cushion material of Comparative Example 1 which was prepared under the same conditions as in Example 1.

[0027]

(Comparative Example 2)

Was sealed in the bag-like fabric has a cushioning material of Comparative Example 2 which was created under the same conditions as in Example 1, except that change only the polyurethane resin pieces.

[0028]

(Comparative Example 3)

An internal two-layer structure of the bag-like fabric, is sealed to feather the first layer, except for sealed polyurethane resin pieces to the second layer, compares those created under the same conditions as in Example 1 and Example 3 was of the cushion material. In addition, the inclusion amount of feather and polyurethane resin pieces, weight ratio 65:35 (Feather polyurethane resin pieces).

[0029]

(Test 1 : durability test) Cushion material of the examples and comparative examples were tested along the "test standard performance and measurement test endurance test of mattress: JIS S 1102:2004". Test content: vertical load testing machine HAIDA INTERNATIONAL Inc. "HD-1086-T Mattress Edge Durability Tester" using (see photograph of FIG. 2) 160 ± 10 times/min at 80,000 times a load on the mattress of 1000N.

Durability judgment, durability of determination is carried out in a condition is satisfied whether the acceptance of the following a) ~ d). Mattress durability of the pass conditions a) Amount of 40mm or less or more (pressure sensor is the position the 0 felt the 5N, to see the difference before and after the test)

b) Outer deviation, fray, tear there is no

c) Stuffing move, fall, out there is no such

d) Spring is broken, it is not like there is no out

[0030]

(Test 2: breathable test)

Breathable judgment, was carried out by testing the wet divergent with a constant temperature bath.

Figure 3 HAIDA INTERNATIONAL Corp. shown in photograph (China) was used thermostat Temperature Humidity Chamber "HD-E702-150B", set the thermostatic chamber was placed a cushion material of Examples and Comparative Examples 40°C, I put in 4 hours after the 27 degrees of ambient temperature environment. The FLIR Inc. Thermal Camera [i7] cushion material of the examples and comparative examples after 5 minutes using, I will measure the temperature. Result of the temperature measurement is obtained in the temperature distribution image as shown in FIG. Numerical value of the temperature is displayed in the upper left corner of the temperature distribution image.

[0031]

(Test 3 : drape test)

Was determined drape by comparing the data after the durability test before and testing of the contact area with the body pressure test.

As shown in the photograph of Fig. 5, use MESTEC manufactured by the (Taiwan) pressure dispersion measuring "Bedding fit", height 172cm, a man of weight 62kg as subjects, obtained from the results of this pressure dispersion measuring instrument the Support Area [cm2], which is I to compare the difference of the number in before and after the test. In addition, I show the area where the body is in close contact with the pressure sensor of pressure dispersion measuring machine and support area. Surface is higher this number is large soft, I said that the mattress is along the surface of the body. Figure for Support Area

[cm2] is, as shown in Figure 6, are calculated from the pressure dispersion measurement image is displayed on the image upper left corner.

[0032]

(Evaluation)

Are shown in Table 1 summarizes the results obtained in the tests 1 -3. In addition, for the test 1, in addition to each of the acceptability determination of Examples and Comparative Examples, I have also shown specific values obtained in the test for the amount or to a). [Table 1]

In test 3, the upper part numbers before the durability test, the lower is the numerical value after durability test.

[0033]

In Comparative Example 2 (Urethane pieces only) in Test 1 (Durability Test), large amounts sag, test was rejected. This deviation is caused by the shock in the back of the urethane packaging is because it was not obtained a repulsion to the sensor unit.

[0034]

For Test 3 in (drape test) Comparative Example 1 (only feather), Support Area is smaller than but begin embodiment there is no change in the drape before and after the test, the surface is turned into hard mattresses.

In Comparative Example 2 (Urethane pieces only), those after the test becomes large Support Area. This is because it is settling in the urethane in the test 1 occurs, load section dent, it is because the contact area is increased, not the improved drape. When settling has occurred, the sleep position is lost, comfortable deteriorates during actual use.

For Comparative Example 3 (Feather urethane separation encapsulation), later tested as in Comparative Example 2 becomes larger Support Area. This is because it is settling in the urethane in the test 1 occurs, load section dent, it is because the contact area is increased, not the improved drape. When settling has occurred, so collapses the actual sleeping during use position, comfortable deteriorates.

INDUSTRIAL APPLICABILITY]

[0035]

As described above, the cushion material of the present invention, while maintaining a low resilience possessed by the warmth and foamable resin feather has, excellent durability due to ventilation and use and disadvantages and foamable resin feathers inherent Since the reducing the disadvantages resulting from you into small pieces, and the seat surface and backrest of a chair or sofa, quilt, cushion, mattress, is a material having high economical and added value that can be used, such as for a mattress, the usefulness of industrial extremely large.
