Embodiment 1

[0081] 1. Feather protein source: raw chicken feather

[0082] The pretreatment process of waste chicken feathers is as follows: waste chicken feather fibers are destemmed and impurity removed, quills are removed, washed with water, alkali adjusted, decolorized, dechlorinated, washed with water, squeezed and dehydrated, dried, and cooled to obtain raw chicken feathers.

[0083] Destemming and impurity removal, removal of quills: mechanical impurity removal machine, air separation;

[0084] The first washing: water, 60min, room temperature;

[0085] Alkali adjustment: NaOH, concentration 0.06-0.10g / L, the purpose of alkali adjustment is to ensure that the solution is weakly alkaline during decolorization;

[0086] Decolorization: decolorizing agent NaClO (sodium hypochlorite), the mass ratio of chicken feather dry basis to water: 5 / 95, the amount of sodium hypochlorite accounted for 0.8% of the chicken feather dry basis, temperature 45-50°C, time 120min;

[0087] Dechlorination...

Embodiment 2

[0105] 1. Feather protein source: hydrolyzed chicken feather powder

[0106] The pretreatment process of waste chicken feathers is: destemming and impurity removal of waste chicken feather fibers, removal of quills, washing, alkali adjustment, decolorization, dechlorination, water washing, pressing and dehydration, high temperature and high pressure sealed hydrolysis, exhaust, discharge, pressing and dehydration, Dried, cooled and crushed to obtain hydrolyzed chicken feather powder.

[0107] Destemming and impurity removal, removal of quills: mechanical impurity removal machine, air separation;

[0108] The first washing: water, 60min, room temperature;

[0109] Alkali adjustment: NaOH, concentration 0.06-0.10g / L; the purpose of alkali adjustment is to ensure that the solution is weakly alkaline during decolorization;

Abstract

The invention discloses a regenerated chicken-feather protein viscose fiber which contains 10-30% of regenerated chicken-feather protein based on the mass percentage of fiber total dry basis in fibers. The preparation method comprises the following steps of: pre-treating waste chicken feathers; extracting chicken-feather proteins and preparing a regenerated chicken-feather protein stock solution;mixing, spinning and post-treating the regenerated chicken-feather protein stock solution and viscose; and finally obtaining finished-product regenerated chicken-feather protein viscose fibers. The regenerated chicken-feather protein viscose fiber disclosed by the invention has the advantages of pure natural property, degradability, softness, excellent dyeing property and the like, and further integrates the advantages of protein fiber and cellulose fibers; the interiors and the surfaces of the regenerated chicken-feather protein viscose fiber contain various amino acid which is necessary forhuman bodies, and the regenerated chicken-feather protein viscose fiber has unique skin-care healthcare functions; the fabric is soft and full of gloss, and the fabric is smooth in hand feeling, moisture-permeable and ventilating; and the fabric can be taken as a textile raw material with great weaving property and service performance, and is a kind of high-grade clothing fabric, in particular being suitable for material selection of clothing fabric, such as underwear, casual clothing and the like of women and children.

Description

technical field [0001] The invention belongs to the field of textile industry, and relates to a viscose fiber made of regenerated chicken feather protein, and also relates to a preparation method and application of the regenerated chicken feather protein viscose fiber. Background technique [0002] With the continuous improvement of living standards, people have more and more strict requirements on the performance of clothing fibers and textile fabrics. The requirements for clothing have exceeded the requirements for keeping warm and covering the body. At the same time, they must also meet the requirements for environmental protection and health care. Natural fibers have good hygroscopicity, and the fabrics made of them have excellent wearability. However, due to the limitation of planting and geographical conditions, the output can no longer meet the needs. After entering the 20th century, cellulose fibers with viscose fibers as the main body and synthetic fibers with "vin...
