Embodiment 1

[0049] A functional regenerated fiber containing protein, which can be produced through the following steps:

[0050] 1. Prepare purified water. The water required in the production process is purified water.

[0051] 2. Sodium hydroxide solution for protein preparation: extract and purify defatted soybean meal, rapeseed meal (low glucoside, low erucic acid) and cottonseed meal (requires dephenolization) by alkali-soluble acid precipitation method After the protein is purified, the varieties are differentiated and stored; casein is extracted and purified from milk, and stored for later use. Take 50 grams of soybean protein, 19 grams of rapeseed protein, 10 grams of cottonseed protein and 20 grams of casein, and add them respectively to a sodium hydroxide solution with a pH value of 12, dissolve for 4 hours, and make a concentration of 20% and a temperature of Protein sodium hydroxide solution at 45°C. The sodium hydroxide solutions of these 4 proteins were then mixed togeth...

Embodiment 2

[0061] A functional regenerated fiber containing protein, which can be produced through the following steps:

[0062] 1. Prepare purified water. The water required in the production process is purified water.

[0063] 2. Sodium hydroxide solution for protein preparation: extract and purify defatted soybean meal, peanut meal, sunflower seed meal, corn meal, ramie meal and wheat kernel protein by alkali-soluble acid precipitation method, and purify After that, the varieties are distinguished and placed; egg white protein and casein are extracted and purified from eggs and milk, and placed for later use. Take 20 grams of soybean protein, 10 grams of wheat protein, 10 grams of peanut protein, 10 grams of sunflower protein, 10 grams of corn protein, 5 grams of ramie protein, 5 grams of egg white protein and 5 grams of casein protein, and mix these 8 kinds of protein together , added into a sodium hydroxide solution with a pH value of 11.5, and dissolved for 3 hours to prepare a p...

Embodiment 3

[0074] A functional regenerated fiber containing protein, which can be produced through the following steps:

[0075] 1. Prepare purified water. The water required in the production process is purified water.

[0076] 2. Sodium hydroxide solution for protein preparation: extract and purify defatted soybean meal, dephenolized cotton meal, canola meal, peanut meal, sesame meal cake, sunflower seed meal, ramie meal by ultrafiltration After purification, the proteins in corn kernels and wheat kernels should be separated and stored; egg white protein and casein protein were extracted from animal hair, eggs and milk, purified, and stored for later use. Take 10 grams of soybean protein, 10 grams of cottonseed protein, 10 grams of rapeseed protein, 10 grams of wheat protein, 10 grams of peanut protein, 10 grams of sesame protein, 5 grams of sunflower protein, 9 grams of corn protein, 5 grams of ramie protein, 5 grams of Keratin, 5 grams of egg white protein and 10 grams of casein, t...

Abstract

The invention relates to the technical field of regenerated fibers, especially to a functional protein regenerated fiber and a manufacturing method thereof. The functional protein regenerated fiber comprises, by weight, 1 to 99 parts of protein, 1 to 99 parts of polyvinyl alcohol and 0.035 to 9 parts of amino acid and / or amino acid hydrochloride. Compared with the prior art, the invention has the following advantages: amino acid and / or amino acid hydrochloride is added to improve secondary and tertiary structures of protein molecules, so the degree of polymerization of the regenerated fiber is increased, and the prepared fiber is firmer.

Description

technical field [0001] The invention relates to the technical field of regenerated fibers, in particular to a functional protein regenerated fiber and a manufacturing method thereof. Background technique [0002] Protein regenerated fiber is a kind of composite fiber material obtained by blending or grafting copolymerization of animal and vegetable protein with high molecular polymer, and then post-processing. Commonly used animal proteins include: milk protein, keratin, egg white protein, etc.; commonly used vegetable proteins include soybean protein, peanut protein, rapeseed protein, etc.; commonly used polymers include polyvinyl alcohol, polyacrylonitrile and regenerated fiber Su and so on. Protein regenerated fiber and its textiles have excellent skin-friendly properties, smooth and comfortable body feeling, and are especially suitable for making underwear, children's clothing and high-end textiles, and are deeply loved by consumers. Animal and vegetable protein raw ma...
