2. Description of the Related Art Conventionally, a sole material for athletics has been made of a plastic molded product or the like, and has been completed in a tread pattern suitable for a running method of a player and a condition of a road surface. For walking on snowy roads, the tread pattern is made of a material such as rubber and has a deep tread pattern. For the sole material, the ability to grasp the road surface, flexibility, and lightness are particularly important. In the case of conventional sole materials, various tread patterns are devised in order to enhance the graspability of the road surface, so that the sole material often becomes thick. Therefore, there has been a problem that as the thickness increases, the flexibility of the sole material itself decreases and becomes heavier. Further, in the case of expressing the design, there is a problem that the process is complicated, for example, a combination of members having different colors is combined into one sole material.

[0003]

The object of the present invention is to provide a sole material which is excellent in road surface graspability, flexibility, lightness and design.

FIG. 1 is a diagram illustrating a method for producing a staple nappi knitted woven fabric in which stamina naps (23) are respectively formed in 1). When a three-dimensional fabric is formed by a moquette loom, a middle portion of the connecting yarn can be subsequently cut by a knife on the loom to obtain a stabbed napped woven fabric. By these methods, a staple nappi knitted woven fabric ( F4) having a normal cut shape is produced. The stabbed knitted woven fabric (F3) is obtained by deforming the tip of the stabbed nap of the stabbed knitted woven fabric. As a method of deforming the tip, for example, a stabbed nappi knitted woven fabric
As shown in FIG. 6 , there is a method of passing a scalp upright (33) which is thermally deformed into a spherical or mushroom-like shape from a scalp scalpel (32) having a normally cut end. Napped knitted woven fabric (F
3) can be. Needless to say, it is also possible to use a stabbed napped knitted woven fabric having stabbed naps whose ends are spherically thermally deformed and stabbed naps in a cut state on the same cloth.

In the present invention, the fiber material used for the ground tissue may be any of synthetic fiber, regenerated fiber, natural fiber, metal fiber, inorganic fiber, etc., and may be used alone or in combination. The structure used for the ground structure may be any of a flat structure, a mesh structure, and a mixed structure thereof.

In the present invention, the material of the staple napping of the staple napping knitted woven fabric uses a monofilament of synthetic fiber in order to form a projection having rigidity suitable for a road surface condition.
Or synthetic filament monofilament and multifilament
To use both of them, and to select and use their thickness. Nylon 6, which is used as a synthetic fiber for
Nylon 66, polyethylene, polypropylene, polyester and the like are preferred. Further, when deforming the tip of the barbed nap, it is preferable to use a fiber having a low softening point, such as polyethylene or polypropylene. In order to produce thermally deformed stabbed naps and cut stubbed naps on the same fabric, a gas burner having a significantly different softening point, for example, a stabbed napped woven fabric having polyester and polypropylene as the stabbed naps. If passed through the top, polypropylene having a low softening point will be deformed at the tip, and polyester having a high softening point will not be deformed.

Practically , the diameter is preferably 0.17 to 0.39 mm. In the case of using a monofilament barbs napped, because it may peeling of the coating resin is a problem, it can be used in combination synthetic fiber multifilaments and monofilaments barbs napped as in FIG. In this case, the synthetic fiber

[0011] In the present invention, the spines are formed at a density of 1 to 20% of the structure point of the ground tissue. If it is less than 1%, it is difficult to develop road surface graspability. 20%
If it exceeds, the density of the pilging is too high and not only the road surface graspability is reduced, but also the resin coating method becomes difficult. The length of the barbed naps is preferably 0.5 mm to 2.0 mm in order to prevent buckling and to make the road surface excellent in graspability. In addition, it is effective to use colored fibers for the ground structure and nap to enhance the design.

There is no particular restriction on the arrangement of the stabbed naps, and the arrangement is uniform or nearly uniform over the entire surface, and is a geometric pattern such as a dot, a straight line, a curve, a lattice, an oblique line, a diamond shape, a honeycomb shape, or the like. The arrangement and other patterns are basic patterns. These tissues can be arbitrarily selected singly or in combination. Next, the main points in the preparation of the stab-like raised knitted woven fabric used for the sole material of the present invention will be described. First, the napped state needs to be in a state perpendicular or nearly perpendicular to the ground tissue, and in a state nearly parallel to the ground tissue, it is difficult to develop road surface graspability. Therefore, it is preferable to devise the structure so that the nap thread becomes vertical nap, or to perform heat treatment after weaving and weaving before the center cutting step, and heat-set the connecting yarn so that the nap state is reliably maintained. It is also effective to perform scouring to remove oils and fats adhering to the stabbed nap fibers in order to enhance the adhesive effect with the coating resin. If the scouring is performed at a relatively high temperature (60 ° C. or higher), the heat setting is performed. The effect will be obtained at the same time. The barbed nappi knitted woven fabric obtained as described above may be heat-set at a temperature of around 150 ° C. for the purpose of dimensional stability, curling prevention, etc. using a pin tenter or the like.

The resin may include a pigment, a modifier, and the like. In addition, when the design of the stabbed knitted woven fabric is directly reflected on the design of the sole material, a transparent or nearly transparent resin is required. Coating methods include, for example, reverse, air doctor, gravure, spray, curtain, extrusion, rod, cast, knife, impregnation methods,
Coating by powder coating, electrostatic coating, vacuum coating, etc., drying method according to coating method and resin,
For example, the resin is fixed by hot air injection, air floating, air through, infrared rays, ultraviolet rays, microwaves, or natural drying.

[0014]

The sole material according to the present invention has a protruding portion made of resin coated on a stabbed nap-knitted woven fabric having a stabbed nap, and the staple nap, serving as the core, is a synthetic fiber filament. Because it is molecularly oriented and has excellent tensile strength and bending resistance, it can be used as a sole material with good durability even with a small amount of coating resin, and it is possible to obtain lightweight shoes with good road surface graspability. Can be. In addition, by using monofilaments or multifilaments of synthetic fibers as appropriate for the staples, the sole material can be adapted to the road surface condition, and the ground tissue or the staples are coated with a transparent resin using colored fibers. In addition, the design can be improved by using a resin to which a pigment is added.
