Embodiment 1

[0017] Embodiment 1. animal or aquatic organism bone powder, according to the ratio of 1: 10 to water, soak in the hydrochloric acid aqueous solution of pH4.3, temperature, stir and wash 90 minutes in 30 ℃. Use a centrifuge to separate the waste liquid, and the separated raw materials are soaked in an aqueous sodium hydroxide solution with a pH of 8.5 and a temperature of 40°C according to a material-to-water ratio of 1:12, and 3% of the weight of the raw materials is added. , 0.2% ethylenediaminetetraacetic acid, 0.1% ascorbic acid, extracted for 50 minutes, and then separated to obtain protein emulsion. Then adjust the pH value to 4.7, and then separate to obtain protein curd.

Embodiment 2

[0018] Embodiment 2. Soybean meal is soaked in the ratio of 1: 11 by material-water ratio and is soaked in pH4.4, and temperature is that in the sulfuric acid aqueous solution of 33 ℃, stirring and washing for 110 minutes. Use the centrifuge to separate the waste liquid, and the soybean meal after the separation is soaked in the potassium hydroxide aqueous solution of PH9 and temperature at 45°C according to the ratio of material to water 1: 12, add 4% potassium sulfite, 0.35% potassium hydroxide respectively Ethylenediaminetetraacetic acid, 0.25% ascorbic acid, extract for 70 minutes, separate the slag to obtain a protein solution, then adjust the pH value to 4.9, and then separate to obtain a protein curd.

Embodiment 3

[0019] Embodiment 3. The sunflower kernel meal is subjected to the same process as in Example 1 or 2, and the pH value of washing is at 4.5, and the temperature is washed in water for 120 minutes in an aqueous phosphoric acid solution at 35° C. After centrifugation, the ratio of material to water is 1: 12. Soak pH9.5, temperature is 50℃, add 5% ammonium sulfite, 0.5% disodium edetate, 0.4% sodium ascorbate respectively, extract for 90 minutes, after separation, adjust pH5.2, and then separate the same Get protein curds.

Abstract

The protein fiber spinning solution is produced by using animal and plant material and through the processes of acid pickling, extraction, pH regulation to obtain protein curd, dissolving with cosolvent to form water solution, mixing, modifying side chain of amino acid with modifying agent, copolymerization with coloring monomer, mixing with PVA water solution and addition crosslinking agent to regualte viscosity. It may be used in spinning fiber with the same strengt has chemical fiber, the skin friendship, air penetrability and hygroscopicity the same as natural protein fiber, and improved hot water resistance, shrinkage and color.

Description

1. Technical field [0001] The invention relates to a novel textile material spinning stock solution, in particular to a protein synthetic fiber spinning stock solution synthesized from animal and plant mixed protein, sodium ethanol sulfonate and polyvinyl alcohol and a production method thereof. 2. Background technology [0002] Known synthetic animal protein fibers are mainly milk protein fibers. The newly listed vegetable protein fiber is mainly soybean protein fiber. But in the production of protein fiber, its spinning dope is the key to fiber production. And the milk protein fiber spinning dope and the vegetable protein fiber spinning dope produced at present all are protein (casein for milk protein fiber, soybean protein for plant protein fiber) are simply dissolved and then blended with polyvinyl alcohol solution And made. Spun into fiber with this spinning dope, the former exists to use milk protein cost high, and raw material is in short supply. Although the latt...
