Problems solved by technology

The above-mentioned animal protein resources are discarded without being used, in addition to causing environmental pollution, it is also a great waste of resources
In addition, Tenebrio molitor raised by farmers in recent years is rich in high-quality protein, which can only be used as feed at present and has not been fully utilized.

example 1

[0015] Example 1: Get 100kg of washed wool, immerse in 1000kg of 5% sodium sulfite aqueous solution, dehydrate after 10 hours, wash the wool once with clear water and spin dry. Add 1000kg of saturated calcium hydroxide aqueous solution and raise the temperature to 80°C. As the dissolution time increases, the pH value continues to decrease. Add sodium hydroxide to adjust the pH value in time to keep the pH value at 9.5-10.5 at a temperature of 80°C. After 4 hours, the wool was basically dissolved, and 20 kg of hydrogen peroxide with a content of 50% was added successively to completely dissolve the wool. After the solution is filtered to remove impurities, the pH value is adjusted to 6 with sulfuric acid, and the unreacted calcium ions and sulfuric acid form calcium sulfate precipitation. After the calcium sulfate is removed by filtration, the pH is adjusted to 4.5-4.8 with hydrochloric acid, the protein is precipitated, and 60-70 kg of wool keratin can be obtained through sepa...

example 2

[0016] Example 2: Take 12kg of gelatin made of cortex, add 10kg of normal temperature water, soak for 30 minutes, add 200kg of 70-80℃ hot water and stir to fully dissolve the collagen, then dissolve it into 320kg of zinc chloride to make collagen zinc chloride Aqueous solution, adjust the pH to 2, stir at room temperature for 30 minutes to make it acid-denatured, heat up to 98 ° C for 30 minutes, heat denature the protein, cool down to 60 ° C, add 500 g of hydrogen peroxide (hydrogen peroxide content 50%), and react for 30 Minutes, add 200g of sodium bisulfite to react for 30 minutes to make denatured protein zinc chloride solution. Then add 200g of ammonium persulfate, 200g of ascorbic acid, add 26kg of acrylonitrile monomer and 3kg of methyl methacrylate under the protection of nitrogen, heat up at 70°C and react for 50 minutes to obtain a collagen protein-acrylonitrile with a solid content of 7.7%. A monomer and a second monomer are grafted and copolymerized into a spinning...

example 3

[0017] Example 3: Take dry insects (tenebrio molitor, fly maggot, bean worm, chrysalis, silkworm chrysalis, etc.) The oils and fats are extracted, and the ratio of insects to No. 6 solvent oil is 1:10, and then drying and desolventization (solvent recovery) to obtain insect residue particles with a protein content of more than 80%, and then dissolve them in sodium hydroxide or Dissolve potassium hydroxide or calcium hydroxide in water, keep the pH between 9-10, soak at 40-50°C for 120 minutes, separate the residue to obtain insect protein emulsion; adjust the pH to 4.7-5.2, and separate the precipitate Get protein curds. Take 100kg of insect protein emulsion with a concentration of 10%, add 100kg of water, dissolve in 290kg of zinc chloride, and make an aqueous solution with a protein concentration of 2% and a zinc chloride concentration of 59%, add hydrochloric acid to adjust the pH to 2, and stir at room temperature for 30 minutes , heated up to 95°C, kept warm for 30 minut...

Abstract

A process for preparing the raw dope for animal protein and acrylonitrile graft-copolymerized fibre includes such steps as purifying animal protein, dissolving in the aqueous solution of zinc chloride, regulating pH value, heating and denaturing, adding hydrogen peroxide to modify the side chain of amino acid, adding reducer to remove excessive oxygen, adding trigger, and graft copolymerization between acrylonitrile and animal protein under protection of N2 gas. Its advantages are use of animal leftover as raw material and low cost.

Description

1. Technical field [0001] The invention relates to a production method of a novel textile material spinning stock solution, in particular to a production method of an animal protein and acrylonitrile graft copolymerized fiber spinning stock solution. 2. Background technology [0002] Known artificially synthesized protein fibers include plant proteins such as soybeans and peanuts, milk, silkworm chrysalis proteins and polyvinyl alcohol or acrylonitrile blending and copolymerization fibers. Most of the above-mentioned protein raw materials have been widely used in the fields of food, beverage and medicine. Various animal hairs (such as wool, camel hair, yak hair, rabbit hair, pig hair) as natural animal protein raw materials are not only directly used in wool spinning, but also a large amount of short hair and waste hair are treated as garbage; In addition to being used as leather clothing, leather shoes, and leather goods, leather also has a large number of broken skins and...
