Problems solved by technology

[0002] Natural protein fibers, such as real silk, are made from silkworm cocoons. This fiber has good hygroscopicity, softness and luster, and is comfortable to wear. However, the production cycle is long, the output is limited and the price is relatively high.
For this reason, some synthetic protein fibers have been developed at home and abroad, such as the Japanese milk protein fiber "chinon", which is made by separating casein protein from milk and then mixing it with acrylonitrile, but casein is expensive, so it is produced relatively high cost

Embodiment 1

[0028] Take the rawhide after depilation and liming, put it into the meat on the meat remover, cut it into 2cm×2cm pieces of skin, put it in a drum, wash it with 3 times 35°C water for 15 minutes, drain the water and then wash it again. After pouring out the water in the drum, add 3 times of 35°C clear water, 2% ammonium sulfate and 0.5% of Pyrene, rotate for 40 minutes, discard the water in the drum, and use 3 times of 35°C Wash twice with water and dry, transfer the cleaned leather to the reaction kettle, add 1.5 times of water, gradually raise the temperature to 80°C, and keep warm for 6 hours to gradually dissolve the raw hide, filter, take the filtrate and concentrate to a concentration of 18 %.

[0029] Analyze the collagen solution, transfer it to the reaction kettle, raise the temperature to 60°C, dissolve the ammonium persulfate with 10 times of water to the collagen content of 1.5%, gradually add it dropwise to the reaction kettle, and simultaneously drop 20% acrylic...

Embodiment 2

[0033] Take the discarded skin flakes from the tannery's gray skin after peeling, put it in the drum, wash it with 3 times 35 ℃ water for 15 minutes, control the water and wash it again, pour the water in the drum, and then add 3 times 35°C water, use 2% ammonium sulfate of skin weight and 0.5% leveling agent, rotate for 40 minutes, discard the water in the drum, wash with 3 times 35°C water twice and control dry, wash clean Transfer the skin pieces to the reaction kettle, add 3 times of water, gradually heat up to 80°C, and keep warm for 4 hours to gradually dissolve the skin flakes, filter, take the filtrate and concentrate to a concentration of 20%.

[0034] Analyze the collagen solution, transfer it to the reaction kettle, raise the temperature to 68°C, dissolve 0.5% ammonium sulfate with 10 times the amount of collagen, gradually add it dropwise to the reaction kettle, and simultaneously drop 5% acrylonitrile mono Body, after adding within 30 minutes, and keep warm for 1....

example 3

[0037] Take the discarded leather shavings from the wet blue leather of the tannery after shaving, put them in the drum, wash them with 3 times 35°C water for 15 minutes, control the water and then wash them again, and transfer the washed leather shavings to the reaction kettle , add 8 times of water and 5% calcium hydroxide of leather shavings, gradually heat up to 90°C, and keep warm for 4 hours to gradually dissolve the leather shavings, filter, neutralize the pH value to 7± with diluted sulfuric acid solution, and then filter The calcium sulfate precipitate was removed, and the filtrate was concentrated to a concentration of 15%.

[0038]Analyze the obtained collagen solution, transfer it to the reaction kettle, raise the temperature to 75°C, dissolve ammonium sulfate with 10 times the amount of collagen to 1% of the collagen content, gradually add it dropwise to the reaction kettle, and simultaneously drop 8% acrylamide And 5% methacrylic acid monomer, after adding within...

Abstract

The present invention relates to new material in textile industry. Collagen protein extracted from animal skin or leather industry leftover is grafting modified with olefin monomer and mixed with PVA to form spinning liquid with certain density and viscosity; and through further wet spinning, solidification, stretching and acetalization, the composite collagen protein fiber for textile industry is produced. The composite collagen protein fiber consists of collagen protein 10-45 wt%, olefin monomer modifier 5-20 wt% and PVA 50-85 wt%. The composite collagen protein fiber has excellent affinity to human skin, high hygroscopicity, wearing comfort and easy colorizing.

Description

technical field [0001] The invention belongs to the new material and its manufacturing method in the technical field of textile industry, and in particular relates to a collagen composite fiber and its manufacturing method. Background technique [0002] Natural protein fibers, such as real silk, are made from silkworm cocoons. This fiber has good hygroscopicity, softness and luster, and is comfortable to wear. However, the production cycle is long, the output is limited and the price is relatively high. For this reason, some synthetic protein fibers have been developed at home and abroad, such as the Japanese milk protein fiber "chinon", which is made by separating casein protein from milk and then mixing it with acrylonitrile, but casein is expensive, so it is produced The cost is relatively high. Soybean protein fiber produced by domestic Huakang Bioengineering Co., Ltd. is a vegetable protein fiber produced by wet spinning by grafting soybean protein with hydroxyl and cy...
