Regenerated animal micropowder protein cellulose fiber and preparation method thereof

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 ...

[0034] First prepare animal micropowder protein: add textile waste wool to 9wt% sodium hydroxide solution, the bath ratio is 1:6, soak at a temperature of 21°C for 60 minutes, wash at a temperature of 35°C, and filter to remove impurities Finally, 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 a 15.8wt% sodium hydroxide solution with a bath ratio of 1:11.5 and a temperature of 31°C. Swell for 105 minutes, then grind to animal protein powder with an average particle size of 8.5 microns by a grinding pump, wash the ground animal protein powder at a temperature of 41°C, and then dry it at 71°C, and dry the dried animal protein powder The protein powder is pulverized to an average particle size of 1.3 microns to obtain animal micropowder protein.
