この発明は、通気性の靴用クッション材に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a breathable cushioning material for shoes.
（従来の技術）

耐久性に問題があった。(Prior Art) Conventionally, as shown in Utility Model Publication No. 45-19647, a synthetic resin sheet provided with ventilation holes and an open-cell flexible foam such as polyurethane foam were layered. Breathable shoe cushioning materials such as insoles have been proposed. However, in this type of cushioning material, ventilation is performed inside the shoe through the ventilation holes provided in the synthetic resin sheet due to the cushioning effect of the open-cell foam.
Since the foam is open-celled, it has good flexibility, but the compression set is large, and repeated compression causes the open cells to close, resulting in loss of cushioning properties and breathability, leading to durability problems. .

The gist of the invention is a breathable cushioning material for shoes characterized by being multilayered.

まう難点がある。As the coiled hollow woven fabric 11 used in this invention, for example, Fiber Coil 3D (trade name) manufactured by Asahi Kasei Corporation is used. This fiber coil 3D is formed into a bag shape with a warp and width triple weave structure, and only the weft thread 101a constituting the core fabric 101 is composed of a heat-shrinkable thread such as a high-pressure polyethylene monofilament thread.
The weft yarns 101a are heat-shrinked by heat treatment after weaving to form woven fabric layers 102 located above and below the core fabric 101.
Weft yarns 102a, 103a made of polyvinylidene chloride monofilament yarns of 103 are formed into a three-dimensional coil shape, and between the woven fabric layers 102, 103 and the core fabric 101, the weft yarns 101a, 102a, 103a and the warp yarns 101b, 1.
This is a woven fabric in which hollow portions 104, 104 are formed continuously in the warp direction by 02b and 103b. The woven fabric in which one synthetic resin monofilament thread is coiled and three-dimensionalized in this way is lightweight and has high resilience, and has good air permeability in the vertical direction through the hollow portion 104 and in the horizontal and vertical directions through the weave, but is flexible. The open-cell foam 13 used in the present invention, which has problems in elasticity and compressibility, includes soft urethane foam, latex foam,
It is composed of ordinary open-cell soft rubber foam, etc., and has good flexibility and compressibility, but has a large compression set, and has the disadvantage of shrinking due to repeated compression and losing rebound resilience.

If the coiled hollow woven fabric 11 is buried and communicated within the shoe, it will be compressed by the landing pressure during walking and running, and will be interposed in the hollow part 104 of the coiled hollow woven fabric 11 and the open cells of the soft foam. The compressed air passes through the hollow portion 104 and the weave 105 of the coiled hollow woven fabric 11 to cause forced ventilation in the shoe in the vertical, horizontal, and vertical directions. Therefore, the breathability inside the shoe is good.

ン体１に長期にわたって良好なりッションを付与する為
、耐久性が良好である。When the landing pressure is released, the high resilience of the coiled hollow woven fabric 11 causes the air inside the shoe to flow into the coiled hollow woven fabric 1.
Air is drawn into the open cells 131 of the soft foam 13 through the hollow portion 104 and the texture 105 of the cushion body 1, and the cushion body 1 is quickly restored to its original state, so that the compression set of the soft foam 13 is improved. Therefore, compression recovery is good and the cushioning effect of the foam 1 is performed smoothly. Moreover, the coiled hollow woven fabric 11 is a synthetic resin monofilament yarn 11.
1, the compression set is small, and the cushion body 1 is provided with good cushioning over a long period of time, so it has good durability.
