Abstract

PURPOSE:To obtain the gas permeable string shoes being excellent in adhesion and durability to a feet by turning vertical a hollow part of coil-like hollow woven cloth in the tightening direction of a tightening band, exposing its upper side part to a gas permeable window and stratifying it, and allowing its lower side part to communicate with a gas permeable groove provided on the shoe bottom part. CONSTITUTION:As for coil-like hollow woven cloth 3, the weft 302a, 303a constituted of polyvinylidene chloride monofilament thread of woven cloth layers 302, 303 positioned in the upper and the lower parts of core cloth 301 is formed solidly, and in the upper and the lower parts of the core cloth 301, gas permeable hollow parts 31, 31 are formed in the vertical direction, and the warp 302b, 303b is placed linearly in the vertical direction. Subsequently, a gas permeable window 22 is provided, and on its reverse side, a tightening band 2 of a structure in which the coil-like hollow woven cloth 3 is stratified is attached to the left and the right instep sides 11, 11, and a gas permeable groove 121 provided on a shoe sole part 12 is allowed to communicate with the inside of a shoe through a gas permeable inner sole 12' provided with air holes 121', 12l', etc., stratified thereon.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to a breathable woven fabric.

(Prior Art) Conventionally, according to Japanese Patent Application Laid-Open No. 113401/1986, a window is provided on the shoe side 11, and a backing material made of a mesh, a coarse lattice cloth, and a breathable liner is exposed through this window. Sexy shoes are suggested.

-However, when such a lace-up structure is embodied in a woven fabric, when worn, the front opening of the lace is tightened with a shoelace, and tightening pressure is applied to the left and right lace-up sides 11, thereby tightening the lace-up side 11. When trying to fit the foot tightly, strong tightening pressure is applied to the leg side 11, and the tensile strength of the backing material is insufficient, resulting in damage to the affected area or insufficient tightening pressure on the leg side 11. However, there is a drawback that the adhesion of the leg side 11 to the foot decreases.

(Problems to be Solved by the Invention) The present invention aims to provide a breathable fabric that has excellent adhesion to the foot and excellent durability.

(Means for Solving the Problems) As explained below with reference to the drawings, this invention has a shoelace hook 21 on the left and right shoe sides 11, 11.11, extending from the sole 12 to the opening 13. .21, at least one of the tightening bands 2 is provided with a ventilation window 22, and a synthetic resin monofilament thread 31 is provided on the back side of this tightening band 2.
The coiled hollow woven fabric 3 made up of
are oriented vertically in the tightening direction of the tightening band 2, and are layered with the upper side 32 exposed to the ventilation window 22, and the lower side 33 is communicated with the ventilation groove 121 provided in the sole 12. The gist of the invention is the characteristically breathable woven structure.

The coiled hollow woven fabric 3 used in this invention includes, for example, fiber coil 3 manufactured by Asahi Kasei Corporation.
D (product name) etc. are used. This fiber coil 3
D is formed into a bag shape with a warp and weft triple weave structure, and only the weft thread 301a constituting the core cloth 301 is composed of a heat-shrinkable thread such as high-pressure polyethylene heptofilament thread, and is heat-treated after weaving. The weft threads 301a are heat-shrinked to form woven fabric layers 302 located above and below the core fabric 301.
, 303, weft yarns 302a and 303a made of polyvinylidene chloride monofilament yarn are made into a three-dimensional coil shape, and air-permeable hollow portions 31 and 31 are formed in the warp direction above and below the core cloth 301, and the warp yarns are 302b and 303b are arranged linearly in the vertical direction, and the woven fabric layer 302.30
This is a woven fabric that has good air permeability in the vertical, horizontal, and vertical directions and has excellent tensile strength in the vertical direction between the core fabric 301 and the core fabric 301.

In this invention, the tightening band 2 having a structure in which a ventilation window 22 is provided and a coiled hollow woven fabric 3 is layered on the back side thereof may be attached to either the left or right side 11, 11.11. , may be both. In this invention, the ventilation groove 121 provided in the sole 12
is communicated with the inside of the shoe via a breathable midsole 12' layered thereon and provided with ventilation holes 12P, 121'', etc.

(Operations and Effects of the Invention) Since the present invention is constructed as described above, when the shoe is increased in use, the air inside the shoe is removed through the ventilation grooves 121 provided in the sole 12 and the hollow portions 31 and 31 of the coiled hollow woven fabric 3. ..., reaches the ventilation window 22 of the tightening band 2, and the ventilation window 22
Weft yarn 302a of woven fabric layers 302, 303 exposed to
, 303a or the gaps between the warp yarns 302b and 303b, which allow communication with the outside air, resulting in good ventilation inside the shoe. In addition, the tensile strength of the tightening belt 11F2 in the vertical direction is strengthened by the warp threads 302b and 303b of the woven fabric layers 302 and 303 of the coiled hollow woven fabric 3, so even if the tightening bands 2 and 2 are tightened with shoelaces when worn. , bow r
The laces 11, 11.11 can be brought into close contact with the feet by the laces 2.2 without damaging the ventilation windows 22 of the laces 2, 2.
