The Animal Skin fiber is the fiber that adopts Animal Skin such as ox, horse, mule, donkey, camel, deer, sheep, pig, dog, wolf, rabbit, mouse, kangaroo, crocodile, fish and snake or leather to make among the present invention, and the length of Animal Skin fiber is 10～45mm, fineness 0.3D～2.5D;
Other textile fabric among the present invention can be long fiber, it also can be staple fibre, both can be natural textile fiber as cotton, fiber crops, silk, Cashmere and Woolens, camel's hair camel hair, the rabbit suede rabbit hair, dog suede dog hair, Down and Feather etc., also can be chemical fibre such as terylene, acrylic fibers, spandex, polyamide fibre, polypropylene fibre etc. or by artificial refine as fibers such as viscose glue, day silk, soybean, milk, bamboo, crust fat.
Back of the present invention one purpose is achieved in that a kind of production method of Animal Skin yarn, comprise following processing step: by the conventional leather processing technology Animal Skin is processed into leather, then through sorting, swelling, open fibre, come unstuck, decolouring, removal of impurities, classification, be mixed, blowing, combing slivering, drafting, spinning.
The present invention compared with prior art has the following advantages:
(1) but the scope of application of Animal Skin has been widened in Animal Skin fiber yarn tatting, knitting and knit out various high, medium and low shelves fabrics and lining.
(2) Animal Skin fiber yarn tensile strength height, good springiness with its tatting, knitting and the various high, medium and low shelves fabric and the lining that knit out, have stronger elasticity, ABRASION RESISTANCE, thermal insulation, anti-flammability, sound absorption properties, water imbibition.
(3) raw material abundance, with low cost, the utilization rate of animal raw hide has only 20～40%, and all the other 60～80% are cheap defect ware, and the tailing resource of animal's leather is also very abundant, price is cheaper, also exists a large amount of cheap waste and old leathers to remain to be recycled simultaneously in the society.
(4) the invention provides a kind of Animal Skin or production Animal Skin fiber yarns such as cheap leather tailing, waste and old leather of utilizing, the production method of feasible process makes natural resources obtain utilizing more effectively and reasonably.
