example 1

[0012] Example 1: above any vegetable protein or its arbitrarily mixed protein, such as 20Kg of rice bran protein, is dissolved in an aqueous sodium hydroxide solution with a pH value of 8, and the concentration is controlled at 8%, and 0.3% of protein weight is added 60 grams of sodium sulfite, while stirring, slowly heat up to 40 ° C, after the protein is fully dissolved, then when the temperature is raised to 60 ° C, add 300 grams of hydrogen peroxide with 1.5% protein weight, react for 30 minutes, and then rise to 80 ° C , add 5Kg of sodium ethanol sulfonate, heat preservation reaction for 40 minutes, when the temperature rises to 95 ° C, then blend with an aqueous solution made of 75Kg polyvinyl alcohol, add 0.2% of the total weight of vegetable protein, sodium ethanol sulfonate, and polyvinyl alcohol % of 200 grams of sodium bisulfite, and the copolymerization concentration was controlled at 16%, and after 90 minutes of insulated and stirred copolymerization, the spinning...

example 2

[0013] Example 2: Get 30 parts of above-mentioned protein (as sunflower kernel protein) equally, be dissolved in the potassium hydroxide aqueous solution of PH10, make concentration control at 9%, and add the potassium sulfite of protein weight 0.4%, slowly heat up while stirring to 45°C, after the protein is fully dissolved, when the temperature is raised to 68°C, add performic acid with a protein weight of 2.3%, and react for 45 minutes; to 96°C, then blended with an aqueous solution made of 67 parts of polyvinyl alcohol, added vegetable protein, sodium ethanol sulfonate, and potassium bisulfite with a total weight of 4.5‰ of polyvinyl alcohol, so that the copolymerization concentration was controlled at 17.5%, and kept warm After stirring and reacting for 105 minutes, a qualified spinning stock solution can be obtained.

example 3

[0014] Example 3: get 40 parts of above-mentioned any protein (as sesame protein) equally, be dissolved in the sodium hydroxide aqueous solution of PH10, make concentration be controlled at 10% and add the sodium sulfite of protein weight 0.5%, while stirring, limit slowly warming up to 50°C, after the protein is fully dissolved, when the temperature is raised to 75°C, add peracetic acid with 3% protein weight, and react for 60 minutes; 98°C, then copolymerize with an aqueous solution made of 59 parts of polyvinyl alcohol, add vegetable protein, sodium ethanol sulfonate, and sodium bisulfite with a total weight of 7‰ of polyvinyl alcohol, so that the copolymerization concentration is 19%, and keep stirring to react After 120 minutes, a qualified spinning dope can be obtained.

Abstract

The invention is a plant protein synthetic fiber spinning stock solution and its production method, which effectively solves the problems of waste utilization of plant slag and reduction of production cost of spinning stock solution. The spinning stock solution is made of plant protein, sodium ethanol sulfonate and polyvinyl alcohol The method is to add plant protein into 0.3-0.5% sodium sulfite of protein weight according to the specified concentration and pH value, then add side chain modifier after heating up and dissolving, then add sodium ethanol sulfonate at temperature up to 95-98°C When it is time to copolymerize with the dissolved polyvinyl alcohol aqueous solution, and add a specified amount of sodium bisulfite (potassium) and stir. The method is simple, the raw material is abundant, the cost is low, and the product performance is good, and its popularization and application must make creative contributions to fiber spinning.

Description

1. Technical field [0001] The invention relates to a new type of textile material spinning stock solution, especially a kind of vegetable protein, namely protein in oil sunflower, sesame, tea seed, castor bean, coconut meat, linseed and rice bran, sodium ethanol sulfonate and polyvinyl alcohol Synthetic protein synthetic fiber spinning dope and its production method. 2. Background technology [0002] Known artificially synthesized protein fibers include milk protein fibers, cortical collagen protein fibers, hairy keratin fibers, insect protein fibers, plant soybean protein fibers and animal and plant double protein fibers. The production process of various protein fibers is not much different; that is to say, all kinds of protein synthetic fibers have different product costs due to raw material sources and prices, which also lead to differences in quality. At present, there are a lot of cheap plant dregs and meal in life and production, such as sunflower kernel meal, sesame...
