Problems solved by technology

[0003] In the application document with the patent application number 02101961.4, a method for producing protein synthetic fiber spinning dope is disclosed. In this application, the spinning dope contains plant protein and animal protein, which adds new raw materials to the resources for producing fibers. , but what is disclosed in this document is only a kind of spinning stock solution, which is an intermediate product in the production of fibers, and cannot be directly used by people, and although the solution contains two kinds of proteins and polyvinyl alcohol, However, due to the narrow range of the two protein ingredients, the natural resources for making fibers cannot be fully utilized. In addition,

Embodiment 1

[0023] Example 1: Add soybeans that have been soaked in water and wet ground into an alkaline solution with a pH of 9.6, and dissolved at a temperature of 29°C. The ratio of material to water is 1:15, and the dissolution time is 180 minutes. Gelatin is added to an alkaline solution with a pH of 9.6, and dissolved at a temperature of 28°C. The ratio of material to water is 1:40. The dissolution process is 240 minutes. The dissolution process should be stirred, and then stand still to separate and remove the waste residue. To obtain the extract, add hydrochloric acid to the extract to adjust the isoelectric point of the extract to obtain the isolated protein; the obtained plant isolated protein and animal isolated protein are dissolved in a triethanolamine-containing pH 12 with a dry solid weight ratio of 1:29 In the aqueous solution, the initial temperature of dissolution is 30°C and then heated to 91°C, and then the temperature is raised to 95°C, and kept at 95°C for 20 minutes to...

Embodiment 2

[0025] Example 2: Put the crushed and defatted soybeans and cheese protein into a solution with a pH of 7.8, and dissolve them at a temperature of 28°C. The dissolution time is 120 minutes. The dissolution process should be stirred and then left to stand. Separate and remove the waste residue to obtain the leachate. Add phosphoric acid to the leachate to adjust the isoelectric point to obtain the separated protein. The two separated proteins are dissolved in a solution containing triethanolamine with a pH of 1.5 at a ratio of 5:21. The temperature is 40°C, and then heated to 95°C and kept at 95°C for 20 minutes to prepare a protein solution with an As concentration of 5%; add the washed polyvinyl alcohol (PVA) into the protein solution, Blend and copolymerize at a temperature of 95°C, raise the temperature to 98°C and keep for 60 minutes to prepare a spinning solution containing animal and plant proteins and polyvinyl alcohol, and adjust the solution to a concentration of 10%, and...

Embodiment 3

[0027] Example 3: Put the defatted cottonseed meal into a solution with a pH of 9.5, and dissolve it at a temperature of 29.5°C. The ratio of material to water is 1:15, and the dissolution time is 70 minutes. The dissolution process should be stirred. Then let it stand to separate and remove the waste residue to obtain the leachate. Add phosphoric acid to the leachate to adjust the isoelectric point to obtain the plant protein separation. Add shellac to an alkaline solution with a pH of 10. The ratio of material to water is 1:15. Dissolve under the condition of 29.5℃, the dissolution time is 100 minutes, the dissolution process should be stirred, and then stand still to separate and remove the waste residue to obtain the leachate. Add phosphoric acid to the leachate to adjust the isoelectric point of the leachate to obtain animal separation protein; separate the plant Protein and animal separated protein were dissolved in a solution containing triethanolamine with a pH of 3 at a r...

Abstract

The present invention discloses a protein synthetic fibre. It is formed from plant protein, animal protein and polyvinyl alcohol. The ratio of total weight of two proteins in fibre weight is: from 1% to less than 20% to from 20% to 40% of from greater than 40% to 99%, the rest is polyvinyl alcohol, and when the ratio of total weighto f two proteins in the fibre weight is from 20% to 40%, the ratio of one of them in the total weight of proteins is from 1% to 25% or from 75% to 99%. It also discloses the production method of said fibre. The fibre is good in breathable moisture permeability, and has the flexible and good dermophilic property of cashmere.

Description

Technical field [0001] The invention belongs to textile materials, and particularly relates to synthetic fibers composed of plant protein, animal protein and polyvinyl alcohol, and also relates to a manufacturing method of such synthetic fibers. Background technique [0002] In addition to the known protein-containing fiber, in addition to natural silk, Japan has published information on the production of synthetic silk by separating protein from milk in the publication of fiber protein chemistry. This product expands the source of fiber production, in order to further expand the fiber Production, and on the basis of ensuring the good performance of fiber products, the inventor once disclosed a synthetic fiber made of plant protein and a method for manufacturing the fiber in the patent "99116636.1", and in the patent application document with application number 02109966.9 Disclosed is a synthetic fiber with a different plant protein content from the previous application and its m...
