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 ammonium persulfate with 10 times the amount of collagen to 1.5% of the collagen content, gradually add it dropwise to the reaction kettle, and simultaneously drop 2...

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, and gradually add it dropwise to the reaction kettle, and simultaneously drop 5% acrylonitrile monomer , After the addition was completed within 30 minute...

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, heat up to 75°C, dissolve 1% ammonium sulfate with 10 times the amount of collagen in water, gradually add it dropwise to the reaction kettle, and simultaneously drop 8% acrylamide and After adding 5% methacrylic acid monomer within 30 minutes, keep it warm for 3 h...

Abstract

A collagen composite fiber and a production method thereof belong to new materials and a production method thereof in the technical field of textile industry. Collagen is a protein separated and extracted from animal hides or leather industrial waste. After being grafted and modified by adding vinyl monomer modifiers, it is mixed with polyvinyl alcohol and stirred evenly to prepare spinning fibers with a certain concentration and viscosity. liquid, and after wet spinning, coagulation, stretching and acetalization treatment, the collagen composite fiber for the textile industry can be obtained, wherein the raw materials of each component are calculated by weight percentage: collagen content 10~ 45%, vinyl monomer modifying agent content of 5-20%, polyvinyl alcohol content of 50-85%, the sum of the composition weight of the above-mentioned percentages is 100%. The fiber has good affinity with human skin, good hygroscopicity, comfortable wearing and easy coloring.

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...
