Problems solved by technology

[0003] The use of natural protein materials to modify chemical fibers has been reported since the middle of the 20th century. For example, in Japan and China, there are patents for grafting and copolymerizing silk protein, pupa protein, soybean protein and acrylonitrile for the development of modified acrylic fibers. Report (94114071.7, 96116532.4, 02109229.x etc.), the modified polyacrylonitrile fiber has good dyeing performance and luster handle etc., but this aspect technology all does not all can extensive industrial promotion, mainly is that protein can not be in a large amount access restrictions
In the past, the method of dissolving-dialysis was used to produce protein solution, that is, the protein material was dissolved in an alkaline solvent, and the protein was precipitated by adding hydrochloric acid. The cost was high, the route was long, and it would bring certain environmental pollution. , so industrial production is difficult

Embodiment 1

[0028] Take silk or silk spinning scraps as raw materials to produce modified polyacrylonitrile fibers containing 5 parts of protein ultrafine powder and 95 parts of polyacrylonitrile as an example.

[0029] First remove the impurities in silk or silk spinning waste, then cut the silk or silk spinning waste into small pieces of 3-5mm with crushing equipment, and then use ultra-fine powder processing equipment to process it into an average particle size of < 5μm ultra-fine powder.

[0030] Then add 5 parts of silk or silk spinning waste ultrafine powder into 0.5% caustic soda solution with a bath ratio of 1:5, and ultrasonically disperse at room temperature for 30 minutes to make an emulsion with good dispersibility.

[0031] Add the emulsion into the spinning stock solution containing 95 parts of polyacrylonitrile, defoam for 6 hours while stirring, and then process it according to the conventional wet spinning route of acrylic fiber to make silk modified polyacrylonitrile fib...

Embodiment 2

[0033] Take animal hair (wool, rabbit hair, etc.) as raw materials, and produce protein-modified polyurethane (polyester) fibers containing 10 parts of protein ultrafine powder and 90 parts of polyurethane as an example.

[0034] First remove impurities with animal hair (wool, rabbit hair, etc.), then cut the animal hair into small pieces of 3-5mm with crushing equipment, and then use ultra-fine powder processing equipment to process the animal hair cut into small pieces of 3-5mm Made into superfine powder with average particle size <5μm.

[0035] According to the ratio of 10 parts of protein powder and 90 parts of polyurethane masterbatch, the protein powder and polyurethane masterbatch are uniformly mixed to make modified spinning masterbatch, and protein modified polyurethane (polyester) is directly made by melt spinning machine. )fiber.

Abstract

The object of the invention is to provide a modified chemical fiber using natural protein fiber superfine powder and production process thereof. The modified chemical fiber is processed by superfine protein powder and chemical fiber material, in which the protein powder is 5-10%, fiber material is 90-95%. The modified chemical fiber using natural protein fiber superfine powder has an improved wettability, a good anti-static property, a good dyeing performance, and has the effects of wool-like and silk-like. The material is natural protein fiber material with a low price and broad source. The melt spinning and wet spinning will not change the processing craft of the traditional chemical fiber and has a good economic performance.

Description

technical field [0001] The invention relates to a chemical fiber modified with natural protein fiber superfine powder and a production method thereof. Background technique [0002] Chemical fiber occupies a very important position in people's daily life, but with the development of social economy, people put forward new requirements for the characteristics of clothing fabrics. Some disadvantages of chemical fibers, such as poor moisture absorption and air permeability, poor antistatic performance, poor dyeing performance, etc., greatly limit its application in clothing. The research on chemical fiber modification technology has attracted more and more attention from researchers all over the world, among which the use of natural protein materials to modify chemical fibers is a hot spot. [0003] The use of natural protein materials to modify chemical fibers has been reported since the middle of the 20th century. For example, in Japan and China, there are patents for grafting...
