Problems solved by technology

At present, the patent application with the application number 02115722.7 discloses a kind of animal wool protein regenerated fiber spinning stock solution and its manufacturing method, which expands the range of raw materials for the production of fibers, and can also recycle waste, but the invention application only discloses A kind of spinning stock solution, animal hair protein in the stock solution accounts for 25-40 parts, because the content of cystine in animal hair protein is relatively large, and the stability of cystine is poor, so this spinning stock solution should be made The fiber also needs to be matched with an appropriate spinning process, and the fiber produced from this stock solution has a single purpose and poor strength

Embodiment 1

[0015] Example 1: After degreasing and removing impurities, animal hair is soaked in an aqueous solution with a pH of 1.5 and stirred. After 6 hours at a temperature of 70°C, the waste residue is separated and purified, and the isoelectric point of the leachate is adjusted with alkali to obtain protein isolate. ; Dissolve the isolated protein in a soft aqueous solution containing sodium dodecylsulfonate, the dissolution temperature is 15°C, and the dissolution time is 4 hours to make a protein solution; add a certain amount of purified polyvinyl alcohol directly into the protein solution , to make them blend and copolymerize, the temperature is slowly raised to 98°C, and kept for 1.5 hours, during which soft water is added to adjust the concentration, and a spinning solution containing protein and polyvinyl alcohol with a concentration of 14% is obtained, wherein the protein and polyvinyl alcohol The weight ratio of dry solids is 3:97; adding boric acid to the spinning solution...

Embodiment 2

[0016] Example 2: After degreasing and removing impurities, animal hair is soaked in an aqueous solution with a pH of 2 and stirred. After 7 hours at a temperature of 40°C, the waste residue is separated and purified, and the isoelectric point of the leaching solution is adjusted with alkali to obtain isolated protein. ; Dissolve the isolated protein in a soft aqueous solution containing sodium dodecylsulfonate at a temperature of 30°C and a dissolution time of 2 hours to make a protein solution; add a certain amount of purified polyvinyl alcohol directly into the protein solution , to make them blend and copolymerize, the temperature is slowly raised to 98°C, and kept for 3.5 hours, during which soft water is added to adjust the concentration, and a spinning solution containing protein and polyvinyl alcohol with a concentration of 27% is obtained, wherein the protein and polyvinyl alcohol The weight ratio of dry solids is 60:40; adding boric acid to the spinning solution to ad...

Embodiment 3

[0017] Example 3: Soak human hair in an aqueous solution with a pH of 2.3 after degreasing and removing impurities, and stir it. After 4 hours at a temperature of 90°C, separate and purify to remove the waste residue, adjust the isoelectric point of the leachate with alkali, and obtain human hair Isolate protein; dissolve the isolated protein in a soft aqueous solution containing sodium dodecylsulfonate, the dissolution temperature is 60°C, and the dissolution time is 1.5 hours to make a protein solution; add a certain amount of washed pure polyvinyl alcohol directly to the protein In the solution, they are blended and copolymerized, and the temperature is slowly raised to 98 ° C, and kept for 2.5 hours, during which soft water is added to adjust the concentration, and a spinning solution containing protein and polyvinyl alcohol with a concentration of 38% is obtained, wherein protein and polyethylene The weight ratio of alcohol to dry solids is 45:55; add boric acid to the spi...

Abstract

The invention discloses a synthetic fiber containing animal hair protein, composed of protein and poval, where the protein is a separation one extracted from the animal hair and the content of the protein in the synthetic fiber is 1%-25% or 40%-90%. It also discloses a method to make the synthetic fiber. It uses not only the animal hair but also human broken hair as raw material, thus further enlarging the raw material source of making fiber, and the made fiber does not contain unnecessary inorganic chemical composition and will not produce environmental pollution in the making course.

Description

technical field [0001] The invention belongs to textile materials, in particular to a synthetic fiber containing protein extracted from animal hair, and also provides a manufacturing method of the synthetic fiber. Background technique [0002] In the patent application with the application number 91109153.X, a composite fiber with high polymer as the core and pupa protein as the outer layer is disclosed. The inventor discloses a plant protein in the patent with the patent number 99116636.1 Synthetic fibers and methods for their manufacture, which expand resources for fiber production. At present, the patent application with the application number 02115722.7 discloses a kind of animal wool protein regenerated fiber spinning stock solution and its manufacturing method, which expands the range of raw materials for the production of fibers, and can also recycle waste, but the invention application only discloses A kind of spinning stock solution, animal hair protein in the stoc...
