Problems solved by technology

At present, the patent application with the application number 021 15722.7 discloses a kind of animal hair 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 application for the invention is only A spinning stock solution is disclosed, in which animal hair protein accounts for 25 to 40 parts. Since the content of cystine in animal hair protein is relatively large, and the stability of cystine is relatively poor, this spinning stock solution must be prepared Fiber formation 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

[0018] Example 1: After degreasing and impurity removal, animal hair is immersed in an aqueous solution with a pH of 1.5 and stirred. After 6 hours at a temperature of 70°C, it is separated and purified to remove the waste residue, and the isoelectric point of the extract is adjusted with alkali to obtain the separated protein ; Dissolve the isolated protein in a soft aqueous solution containing sodium dodecyl sulfonate at a temperature of 15°C and a dissolution time of 4 hours to make a protein solution; add a certain amount of pure polyvinyl alcohol to the protein solution directly , Make them blend and copolymerize, the temperature is slowly raised to 98 ℃, kept for 1.5 hours, during which soft water is added to adjust the concentration, and a spinning solution containing protein and polyvinyl alcohol at a concentration of 14% is prepared. The dry-to-solid weight ratio is 3:97; boric acid is added to the spinning solution to adjust the viscosity to make spinning dope; the spinn...

Embodiment 2

[0019] Example 2: After degreasing and removing impurities, animal hair is immersed in an aqueous solution of pH 2 and stirred. After 7 hours at a temperature of 40°C, it is separated and purified to remove waste residue, and the isoelectric point of the extract is adjusted with alkali to obtain the separated protein ; Dissolve the isolated protein in a soft aqueous solution containing sodium dodecyl sulfonate at a temperature of 30°C and a dissolution time of 2 hours to make a protein solution; add a certain amount of pure polyvinyl alcohol to the protein solution directly , Make them blend and copolymerize, the temperature is slowly increased to 98 ℃, 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 prepared. The dry solid weight ratio is 60:40; boric acid is added to the spinning solution to adjust the viscosity to make spinning dope; the spinning dop...

Embodiment 3

[0020] Example 3: After removing fat and impurities, human hair was immersed in an aqueous solution with a pH of 2.3 and stirred. After 4 hours at a temperature of 90°C, it was separated and purified to remove waste residue, and the isoelectric point of the extract was adjusted with alkali to obtain human hair Separate the protein; dissolve the separated protein in a soft aqueous solution containing sodium dodecyl sulfonate at a temperature of 60°C and a dissolution time of 1.5 hours to make a protein solution; add a certain amount of purified polyvinyl alcohol to the protein directly In the solution, they were blended and copolymerized. The temperature was slowly increased to 98°C and kept for 2.5 hours. During this time, soft water was added to adjust the concentration, and a spinning solution containing protein and polyvinyl alcohol at a concentration of 38% was prepared. The dry solid weight ratio of alcohol is 45:55; boric acid is added to the spinning solution to adjust the ...

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, and particularly relates to a synthetic fiber containing protein extracted from animal hair. The invention also provides a method for manufacturing the synthetic fiber. Background technique [0002] In the patent application with application number 91109153.X, a composite fiber with high polymer as the core and pupa protein as the outer layer is disclosed. The inventor also discloses a plant protein in the patent with patent number 99116636.1 Synthetic fiber and its manufacturing method, which expand resources for fiber production. At present, the patent application with application number 021 15722.7 discloses an animal hair protein regenerated fiber spinning dope and its manufacturing method. This expands the range of raw materials for fiber production and can also recycle waste. However, this invention application only Disclosed is a spinning dope. The animal hair protein in the dope accounts for 25-40 parts. B...
