Abstract

the invention discloses a feather casein fiber preparation method which comprises the following steps of: A, preparing a feather casein spinning solution. namely, solving feather in an alkaline water solution the mass concentration of which is 0.1%-20%, stirring a period, thus obtaining a casein solution through filtering, wherein the alkaline water solution comprises sodium silicate, silicic acid potassium and calcium hydroxide, and the mass ratio of the sodium silicate, the silicic acid potassium and the calcium hydroxide is 1:(0.5-1):(0.3-0.5); B, blending a feather casein spinning solution and a cellulose sulfonic acid ester solution and spinning; and C, carrying out coagulating bath treatment, acid cleaning, water washing and drying on feather casein viscose rayon so as to obtain feather casein fiber. The feather casein fiber preparation method provided by the invention can effectively enable the feather casein spinning solution to achieve homogeneous phase degree, thereby achieving the spinning purpose.

Description

technical field [0001] The invention relates to a method for preparing protein fibers, in particular to a method for preparing feather protein fibers. Background technique [0002] Feather and down are keratinized products derived from poultry epidermal cells. Among them, down is a green fiber material with excellent characteristics such as light weight, softness, strong moisture absorption, and good warmth retention. In addition to a small amount of soft down components in feathers , and the rest are rigid pinna component structures. The remaining pinnaes etc. after the existing feather has been extracted are often treated as waste, or are used to make feed; although the existing feed made of pinnae has solved the problem of its waste utilization to a certain extent, but Because the pinna contains a certain amount of bacteria carried by poultry animals, it is difficult to guarantee the quality of the feed produced by it. [0003] The reason why pinnae are not as widely us...
