Description

  The present invention relates to an attachment device such as a fiber attachment device having an assisting portion, a manipulative function, or a shaping function, such as a knee or ankle supporter, a chest or waist corset, or a female underwear bra.

  Wearing devices such as supporters and corsets that are used for assisting the mounting part, and for shaping and shaping, the strength required to demonstrate functions such as assisting the supporting force of the joints, maintaining the body shape or posture and limiting the movable range Elasticity and flexibility or flexibility necessary for adapting to the movement of the human body and obtaining a comfortable wearing feeling are required. In general, it is only a part of the body that is supported or adjusted by this kind of wearing device, so it is sufficient that these wearing devices have a region with strength or elasticity in a part of it. It is desirable that other regions have flexibility to fit the body.

  For example, in the case of a knee supporter for assisting the support force, a support member with high strength and elastic restoring force is placed on the side of the knee, and the corset to be worn on the waist is the necessary part around the waist The underwear for shaping the shape of a woman's breast is a structure in which an elastic belt-like sheet or wire is attached to the lower part of the cup that supports the breast. It has become.

  Conventionally, in this type of mounting tool, a shell-like, strip-like, or wire-like hard member that requires a supporting force or elastic restoring force is manufactured from a metal or plastic molded product, and the hard member is made of a knitted fabric. A desired strength or elasticity is imparted to a necessary portion by sewing, bonding, or insertion to a flexible base material.

However, since the mounting device having the conventional structure as described above, the mechanical properties such as strength and flexibility change drastically and discontinuously at the joint between the hard member and the flexible base material, The hard member breaks through the flexible base material and protrudes to damage the human body, or when subjected to external force, a large concentrated stress is generated in the sewn part and the adhesive part between the hard member and the base material, making it easy to peel off. There was a problem.
JP 11-140709 A

  The present invention is caused by the above-described problems of the prior art, that is, discontinuity or non-integration between a hard member and a flexible base material in various wearing devices having assistance of support force and trimming or shaping function. It is an object of the present invention to obtain technical means for fundamentally solving problems such as protrusion and peeling of a hard member from a base material.

  The present invention solves the above-mentioned problems by integrating or continuating a hard region necessary for assisting support force, trimming or shaping, and a flexible region for imparting flexibility and a comfortable wearing feeling. is doing. That is, the wearing tool of the present invention is a non-hardening yarn having a flexible yarn that can later give the strength and elasticity required for the hard region, and the flexibility or touch required for the flexible region. After forming a single woven structure, a knitted structure or a braided structure using the stripes in each region, the fibers of the hard region yarns are cured by heat treatment, so that the desired cured region has the desired strength or elasticity. The shape for support or shaping provided with is provided.

That is, textile attachment according to the invention of claim 1 in which the above-described problems, and organized cured region the yarn containing hot-melt resin fibers, stable non also in the melting point of the heat meltable resin A woven, knitted or braided structure comprising uncured regions organized by yarns of hardened fibers, wherein the yarns forming the respective regions at the boundary or junction of the two regions are opposite to each other Necessary for assisting support force or shaping or shaping in the hardened region by heating a structure body woven, knitted, or integrated and integrated to the above-mentioned structure to a temperature higher than the softening point or melting point of the hot-melt resin. A desired shape having sufficient strength or elasticity is provided .

  A preferable heat-meltable resin fiber in the invention is a polyester fiber as described in claim 2. The physical properties imparted to the cured region by heat treatment can be adjusted by the type of heat-meltable resin fiber and the heat treatment temperature, but as described in claim 3, as a yarn containing the heat-meltable resin fiber, the melting point is different. By using a yarn containing a plurality of types of polyester fibers, it is possible to adjust more easily and over a wide range according to the type of the wearing tool.

  The wearing device of the present invention has a hard region and a flexible region that are interwoven with each other with yarns suitable for forming the respective regions, knitted, or assembled into an integrated state, and then heated. Since it is obtained by curing only the hard region into a desired shape by processing, complete integration between the hard region and the flexible region can be obtained. In addition, physical properties such as hardness, elasticity, and flexibility can be continuously changed depending on the degree of weaving, weaving, or incorporation at the boundary between the yarns that form both regions, and the boundary between the hard region and the flexible region. It is also possible to arrange a yarn having properties intermediate between the two in the portion. Therefore, mechanical properties such as strength, elasticity, flexibility and cushioning can be adjusted by selecting the difference in thermal denaturation of the fibers used and the method and degree of heat treatment as appropriate, and areas with different touches can be integrated. And it can form continuously and can solve completely the problem that a hard part detaches | leaves from a flexible part. Furthermore, by continuously changing the physical properties at the region boundary portion, it is possible to obtain a wearing tool having an auxiliary, trimming or shaping function that is more functional and excellent in wearing feeling.
