Problems solved by technology

At present, the use of fiber state still occupies a dominant position. Due to the limitation of textile technology, a large amount of short fibers are often discarded, and at the same time, a large number of dilapidated woolen fabrics cannot be used. This is undoubtedly a waste of limited natural resources.

example 1

[0014] Example 1. Soak clean animal hair in 1.5% aqueous hydrogen peroxide solution for 70 minutes, then adjust the pH value to 10.5 with sodium hydroxide, slowly heat to 100°C, keep warm for 90 minutes, and cool down to 85°C , add 1.2% sodium bisulfite, keep warm for 40 minutes, and finally add 1% sodium ethanol sulfonate by protein weight to make the copolymerization at 75° C. for 40 minutes.

example 2

[0015] Example 2. Soak clean animal hair in 4% aqueous hydrogen peroxide solution for 40 minutes, then adjust the pH value to 9.5 with sodium hydroxide, slowly heat to 100°C, keep warm for 90 minutes, and cool to 85°C. Add 0.6% sodium bisulfite, keep it warm for 30 minutes, and finally add 5% sodium ethanol sulfonate by protein weight to make it copolymerize. The copolymerization temperature is 90° C. and the time is 70 minutes.

example 3

[0016] Example 3. Soak clean animal hair in 3% aqueous hydrogen peroxide solution for 65 minutes, then adjust the pH value to 10 with sodium hydroxide, slowly heat to 100°C, keep it warm for 90 minutes, and cool down to 85°C , add 0.9% sodium bisulfite, keep warm for 35 minutes, and finally add 3% sodium ethanol sulfonate by protein weight to make it copolymerize. The copolymerization temperature is 80° C. and the time is 60 minutes.

Abstract

A raw solution of animal hair's for spinning the regenerated fibres is prepared from animal hair's protein, polyvinyl alcohol, color-substantive monomer, assistant and high-molecular cross-linking agent through defatting the animal hair in alkali solution, adding assistance, dissolving, adding color-substantive monomer, mixing with polyvinyl alcohol, copolymerizing and adding high-molecular cross-linking agent for regulating viscosity.

Description

1. Technical field [0001] The invention relates to a spinning stock solution of a new type of textile material, in particular to a spinning stock solution of animal hair protein regenerated fiber synthesized from protein extracted from animal hair fiber and polyvinyl alcohol and a production method thereof. 2. Background technology [0002] Known animal fibers are mainly animal plush represented by wool. Animal fibers are extremely valuable substances provided by nature to human beings. At present, its utilization in the form of fibers still occupies a dominant position. Due to the limitation of textile technology, a large amount of short fibers are often discarded, and a large amount of dilapidated wool fabrics cannot be used at the same time. This is undoubtedly a waste of limited natural resources. Therefore, how to regenerate these discarded animal fibers into new fibers has become an important research topic. 3. Contents of the invention [0003] The purpose of the ...
