Abstract

A functional fibre of regenerated ceratin is prepared through preparing ceratin solution from goat or sheep wool, camel or yak hair, feather, leather leftover, etc, adding one or more of metal oxide, organic metal compound, chitin, chitosan, cyclodextrin, polyether and polyacrylic acid, which have the antistatic, antibacterial, deodorizing, drying, heating lagging and hydroscopc functions, and spinning.

Description

technical field [0001] The invention belongs to the application field of polymer materials and engineering technology and relates to a regeneration keratin fiber processing technology. Background technique [0002] It is a common practice in the world to make chemical fibers from polymer materials, and various textiles processed from man-made fibers can be seen everywhere in the market today. In recent years, milk fiber and soybean fiber processed by protein have also begun to take shape. The present invention produces functional keratin regenerated fibers from natural keratin raw material resources. At present, the technology of producing keratin fiber by alkaline method has been available in China. After retrieval, the closest thing to the present invention is "Keratin Regeneration Fiber Technology" (patent application number: 99116699, publication number: 1293266), which is a manufacturing method of extracting protein from keratin raw materials and processing it into pr...
