Problems solved by technology

In the early 1940s, the United States developed casein fiber; in 1945, the United States and Britain studied soybean protein fiber; in 1948, General Motors of the United States extracted soybean protein fiber from soybean meal, but most of them could not be processed because of poor fiber performance. Textile processing while interrupting research
[0007] Based on the production technology of protein fibers disclosed at home and abroad, no matter it is viscose fiber or other wet-spun synthetic fibers, it basically adopts the lye treatment of first di

[0033] Example 1 1.67dtex×38mm regenerated animal micronized protein viscose fiber

[0034] First, prepare animal micronized protein: add textile waste wool to 9wt% sodium hydroxide solution, bath ratio is 1:6, soak at 21℃ for 60 minutes, wash at 35℃, filter to remove impurities Afterwards, it is dried in a three-dimensional rotary oven at a drying temperature of 80°C, and then pre-crushed. The pre-crushed wool is added to 15.8wt% sodium hydroxide solution, the bath ratio is 1:11.5, and the temperature is 31°C Swell for 105 minutes, then grind it to an animal protein powder with an average particle size of 8.5 microns by a grinding pump. The ground animal protein powder is washed at a temperature of 41°C, and then dried at 71°C. The dried animal The protein powder is pulverized to an average particle size of 1.3 micrometers to obtain fine animal protein powder.

Abstract

The invention discloses a regenerated animal micropowder protein cellulose fiber and a preparation method thereof. The preparation method comprises the following steps of: adding nanoscale animal micropowder protein into a dispersant solution, stirring the mixture uniformly, filtering to obtain 20 to 35 weight percent of animal micropowder protein liquid; preparing viscose by using cellulose pulp as a raw material, adding denaturant in the dissolution step to obtain modified viscose; adding the animal micropowder protein liquid into the modified viscose in a weight ratio of animal micropowder to the finished fiber of (1-30):100, uniformly stirring to obtain animal micropowder compounding viscose; and defoaming and filtering, spinning molding by introducing a coagulating bath, and then drawing filament and performing aftertreatment to obtain the animal micropowder protein viscose fiber. The fabric made of the regenerated animal micropowder protein cellulose fiber is low in density, and is light; the hygroscopicity, the air permeability and the thermal insulating property of the fabric are further improved; the fiber textile processing and wearability are good; and the production process is pollution-free.

Description

technical field [0001] The invention relates to the technical field of modified cellulose, in particular to a regenerated animal micropowder protein cellulose fiber and a preparation process thereof. Background technique [0002] Protein fibers are divided into two categories: natural protein fibers (such as wool, silk, etc.) and regenerated protein fibers. According to the source of raw materials, regenerated protein fibers can be divided into regenerated animal protein fibers and regenerated plant protein fibers. Regenerated animal protein fiber mainly refers to fiber spun from milk, feathers, wool, pig hair, etc., and regenerated plant protein fiber mainly refers to fiber spun from corn, soybean, peanut, rapeseed, etc. [0003] Foreign countries began to research on regenerated protein fiber from the end of the 19th century and the beginning of the 20th century. Italian scientists in 1935, British ICI Company in 1938, and Corn Product Refining Company in 1939 discussed ...
