Abstract
An insole and a boot are manufactured using a boot interior material which is formed by bonding a surface material with a pad layer acquired by thermalforming elastic compex fibres and web, optionally containing moisture absorbing - heat generating fibres to orientating the fibres towards a thickness direction. The elastic compex fibres comprise matrix fibres containing inelastic polyester staple fiber, thermoplastic elastomer which melting point is more than 40 DEG C than that of a polyester polymer of the staple fiber, and an inelastic polyester, the former at least exposes to the fibre surface.
Description
Technical field
The present invention relates to be used as shoe interior material, and the shoe-pad that constitutes by this shoe interior material, and the inboard boots of being furnished with this shoe interior material of the internal material of footwear inside.Be particularly related to lightweight, resiliency, and shoe interior material, shoe-pad and the boots of gas permeability excellence.
Background technology
At present, as the shoe interior material of the internal material that is used as footwear inside, for example known the material pasting canvas and obtain is arranged on wool, based on the material (for example referring to patent documentation 1, patent documentation 2) of polyurethane foam.But,, when then using shoe-pad, have the problem that Heavy Weight, gas permeability are poor, damp and hot sense is arranged if constitute shoe-pad by above-mentioned shoe interior material.In addition, in case use the material existence of natural fibers such as wool to wash then the problem of resiliency reduction.
Therefore, the shoe interior material of lightweight, resiliency and gas permeability excellence is developed in expectation.In addition, even the shoe interior material that also expectation is developed in the winter time, use also has heat insulating ability under the low temperature environment.
Need to prove, at present, as fiber product with heat insulating ability, the product (for example referring to patent documentation 3, patent documentation 4) that uses esters of acrylic acid moisture absorption heating fiber is arranged, be attached with the shoe interior material (for example referring to patent documentation 5) of moisture absorption heating organic fine particles etc.

Summary of the invention
The object of the present invention is to provide shoe interior material, shoe-pad and the boots of lightweight, resiliency and gas permeability excellence.Above-mentioned purpose realizes by shoe interior material of the present invention, shoe-pad and boots.
Shoe interior material of the present invention is a lamination and be fitted with the shoe interior material of cloth and silk shape superficial layer on liner (mat) layer, it is characterized by,
Contain the elastic composite fiber in the described laying, described elastic composite fiber is made of than the low thermoplastic elastomer (TPE) and the inelastic polyester more than 40 ℃ of fusing point of the polyester polymers that constitutes this short fiber the matrix fiber that contains inelastic polyester class short fiber, fusing point, the former exposes at least at fiber surface
At least one hot adhesion of the contact point of the contact point between the described elastic composite fiber and/or described elastic composite fiber and matrix fiber,
And matrix fiber and elastic composite fiber are towards the thickness direction orientation of laying.
At this moment, described matrix fiber is preferably doughnut.In described matrix fiber, the content of the fiber that generates heat because of moisture absorption is preferably 10～80 weight % with respect to the weight of laying.In addition, in described matrix fiber, the content of high suction water absorbent fiber is preferably 10～80 weight % with respect to the weight of laying.The thickness of described laying is preferably in the scope of 2～10mm.In addition, the weight per unit area of laying is preferably at 200～1500g/m
2Scope in.
Preferably contain polyester fiber in the described superficial layer of shoe interior material of the present invention.And in superficial layer, the content of the fiber that generates heat because of moisture absorption is preferably more than the 20 weight % with respect to the weight of superficial layer.At this moment, the fiber that generates heat because of moisture absorption is preferably esters of acrylic acid moisture absorption heating fiber.In addition, superficial layer is preferably braid.In described laying, the surface of laminating surface layer is preferably the section that is cut.
The shoe-pad of shoe-pad of the present invention for constituting by described shoe interior material.In addition, boots of the present invention are for setting the boots that described shoe interior material constitutes in the inboard.
Description of drawings
