The filament fiber number of composite fibre of the present invention can suitably be set according to object, is not particularly limited, for example, can from the scope of 0.3～50dtex (preferably 0.3～40dtex), select.But, from improving the viewpoint to the suitable sense of human body, preferably the filament fiber number of 0.3～10dtex (preferably 0.3～5dtex).It should be noted that, in composite fibre of the present invention, can prevent fracture of wire, and obtain the fine-titred fiber below 6dtex.These fibers not only can be used as long fiber and use, and can be used as staple fibre or staple fiber use.
The composite fibre of the present invention obtaining as mentioned above can be used as various fiber assemblies (fiber structure).At this, fiber assembly can be enumerated the cloth and silks such as various braided fabrics, nonwoven fabric etc.
It should be noted that, conventionally by remove B composition from these fiber assemblies, can obtain the final products (being polyurethane elastomer cloth and silk) that use with respect to human body.
For example, this polyurethane elastomer cloth and silk can obtain by possessing the manufacture method of following operation, that is, preparatory process, prepares above-mentioned composite fibre; Composite fibre cloth and silk production process, is used above-mentioned fiber to make the cloth and silk consisting of composite fibre; Remove operation, from above-mentioned cloth and silk, remove B composition and obtain polyurethane elastomer cloth and silk.
It should be noted that, above-mentioned composite fibre cloth and silk can be formed separately by composite fibre of the present invention, also braided fabric or the nonwoven fabric of composite fibre of the present invention can have been used for part, such as weaving cotton cloth interweaving of other fiber with natural fabric, chemical fibre, synthetic fiber etc., or as blended ratio, the mixed braided fabric of knitting silk, mixed cotton nonwoven fabric etc.For example, in situation about using with other fiber combinations, shared ratio for example can be for more than 14 quality %, more than can being preferably 15 quality % in knitted woven item or nonwoven fabric for the A composition of composite fibre of the present invention, preferably more than 18 quality %, more preferably more than 23 quality %.In addition, be used as blended ratio, mix in the situation of knitting silk, the ratio of the A composition in it can be for example 14～95 quality %, more than can being preferably 20 quality %, preferably more than 30 quality %, more preferably more than 40 quality %.
By alkali treatment, water treatment etc., from composite fibre cloth and silk, remove polyurethane elastomer cloth and silk that B composition obtains because glass transition temperature is close to human body surface, therefore, excellent with respect to the well-formedness of the dynamic motion of human body.
In addition, the composite fibre using in the application of the invention, the filament fiber number that forms the polyurethane elastomeric fiber of cloth and silk can be set as to for example scope of 0.3～50dtex (preferably 0.3～40dtex), carry out in the situation of fine denier, can make 0.3～10dtex, the preferred fine denier fiber of 0.3～5dtex.
