Abstract
The utility model relates to a three-C combination special-shaped hollow fiber. The outer contour of the section of the three-C combination special-shaped hollow fiber is composed of three C-shaped circular arcs, the three C-shaped circular arcs are connected in an end-to-end mode to form a trilobal section, and a trilobal cavity is formed inside the three-C combination special-shaped hollow fiber. The utility model further relates to a spinneret plate for the three-C combination special-shaped hollow fiber. The cross section of a spinneret micro-hole of the spinneret plate is composed of three identical hollow C-shaped micro-holes, openings of the three hollow C-shaped micro-holes are formed in an inward arrangement mode, and a gap exists between every two adjacent C-shaped micro-holes. Due to the fact that the cross section of the three-C combination special-shaped hollow fiber produced by the spinneret plate is of a special shape and is hollow, elasticity of the three-C combination special-shaped hollow fiber is improved; due to the hollow wicking effect, the capacity of moisture absorption and sweat releasing of the three-C combination special-shaped hollow fiber is improved, and the defects that in the prior art, a fiber is poor in elastic resilience and not obvious in crimp, and elastic fabric is not comfortable in wear are overcome.

The spinnerets that a kind of three combined special-shaped doughnuts of C as above are used, the distance c between the external arc of described two " C " shape micropores is 0.001～0.009mm.
The spinnerets that a kind of three combined special-shaped doughnuts of C as above are used, described hollow " C " shape micropore is elliptic arc, parabolical part or hyp part.
The spinnerets that a kind of three combined special-shaped doughnuts of C as above are used, described spinneret orifice radially distributes on spinnerets centered by the spinnerets center of circle.
The spinnerets that a kind of three combined special-shaped doughnuts of C of the present utility model are used, not only be applicable to PET, PTT, ECDP etc., can promote the spinning for the homogeneous raw material of different qualities viscosity, the fabric of producing can be widely used in sportswear, business wear, indoor decoration, bedding, footgear, medical supplies and senior fill material, has a extensive future.
The beneficial effects of the utility model are:
The spinnerets that a kind of three combined special-shaped doughnuts of C of the present utility model are used, the cross sectional shape of the fiber of producing is special-shaped hollow, not only improve its elasticity, and due to the core sucting action of hollow, improved the ability of its moisture absorbing and sweat releasing, the fiber resilience is good, and curling obvious, elastic fabric is comfortable and easy to wear.The three combined special-shaped doughnuts of C are the novel polyster fibres with moisture absorbing and sweat releasing and thermal property, make its fabric can quick moisture conducting, diffusion and volatilization sweat, thus keep the dry feeling of human body skin, reach and improve the comfort of fabric purpose.
