Problems solved by technology

But acrylic fiber also has many disadvantages: poor hydrophilicity makes it easy to be charged with static electricity in dry weather, and has poor affinity with the human body
But albumen is dispersed with sea-island type in this fiber, when this fiber is washed in conventional detergent (acidic or alkaline), because vegetable protein dissolves in acidic or alkaline solvent, makes the vegetable protein on vegetable protein-acrylic fiber surface in It is removed due to dissolution during washing, which affects the affinity and hygroscopicity of the fiber with the skin, so the fiber is not resistant to washing

Embodiment 1

[0029] Soybean cake was mixed with 10 times its weight of water, soaked at 30°C for 8 hours, and insoluble polysaccharide residues were separated, and these residues were mixed with water at a weight ratio of 1:12, soaked for 1 hour, and the supernatant was taken. The two parts of the solution were combined and the pH value of the solution was adjusted to 4.4 with acetic acid and allowed to stand for 2 hours for acid precipitation. The obtained protein was centrifuged and dehydrated so that its water content was 30% (by weight).

[0030] The above protein is dissolved in a sodium thiocyanate solution with a weight concentration of 30%, so that the protein weight concentration is 10%, and then compounded with the acrylic fiber slurry and the protein solution in a weight ratio of 1:4, and the crosslinking agent is double-shrunk. Glycerin glycol ether is added by 0.5% of solvent weight, and the spinning slurry prepared is left to stand for 12h for defoaming;

Embodiment 2

[0033] Sunflower seed meal and sodium hydroxide solution with a pH value of 8.8 were mixed at a weight ratio of 1:8, soaked at room temperature for 2 hours, and the insoluble polysaccharide residue was separated. The sodium hydroxide solution was mixed in a weight ratio of 1:9, soaked for 1 hour to get the supernatant. The two parts of the solution were combined and the pH value of the solution was adjusted to 4.6 with hydrochloric acid and allowed to stand for 2 hours for acid precipitation. The obtained protein was centrifuged and dehydrated so that its water content was 25%.

[0034] This albumen is dissolved in the zinc chloride solution that weight concentration is 17%, and its protein weight concentration is 10%, and fiber grade polyacrylonitrile is dissolved in the zinc chloride solution that weight concentration is 16%, and protein solution and poly The acrylonitrile slurry is compounded according to the weight ratio of 1:5, and the crosslinking agent glycidyl ether i...

Embodiment 3

[0037] Peanut cake and hydrochloric acid solution with a pH value of 6.8 are mixed in a weight ratio of 1:9, kept at 50°C for 30 minutes, the insoluble residue is separated, and the residue and water are mixed in a weight ratio of 1:10, soaked at 50°C for 30 minutes minutes, the supernatant was separated. The two parts of the solution were combined and the pH of the solution was adjusted to 4.3 with acetic acid and allowed to stand for 1.5 hours for acid precipitation. The obtained protein was centrifuged and dehydrated so that its water content was 20%.

[0038] The above protein is dissolved in dimethylformamide, the protein weight concentration is adjusted to be 10%, fiber-grade polyacrylonitrile is dissolved in dimethylformamide, and the protein solution and polyacrylonitrile solution are mixed in a weight ratio of 1: 4.5. Prepared, the cross-linking agent diglycidyl butanediol ether is added according to 0.4% of the weight of the solvent, and the spinning slurry is left ...

Abstract

The invention discloses an acrylon-crosslink vegetable protein complex fiber and the method to manufacture. The main ingredients of the complex fiber are natural macromolecule vegetable protein and polacryl nitrile. In the process of producing silk, the vegetable protein is being fixed into the polacryl nitrile and cross linking under the effect of crosslink agent. Dispensing the vegetable protein solution and the polacryl nitrile solution separately, and mixing the two solutions under a certain proportion to make filature paste, adding an amount of crosslink agent, after spraying to form fiber, drafting, hot drawing, crimping, typing, adding oil, and drying, the new type complex fiber would be manufactured. The complex fiber mainly maintains the mechanical characteristic, anti-ultraviolet radiation fading capability and washability that the acrylon originally has, moreover, it has the feature of good comfort, antistatic property and dyeing capability that the vegetable fiber has.

Description

technical field [0001] The invention relates to a composite fiber, in particular to an acrylic fiber-crosslinked vegetable protein composite fiber and a manufacturing method thereof. Background of the invention [0002] Acrylic fiber is a kind of synthetic fiber, which has excellent warmth retention property, excellent dyeability and no moth and mildew. After dyeing, it can obtain brighter colors than wool. Acrylic fiber is widely used in the manufacture of wool-like products, so acrylic fiber Also known as artificial wool. However, acrylic fiber also has many disadvantages: poor hydrophilicity makes it easy to be charged with static electricity in dry weather, and has poor affinity with the human body. [0003] In order to improve the performance of these shortcomings of acrylic fibers, researchers have done a lot of work with animal protein modified acrylic fibers, such as silk grafted with polyacrylonitrile, milk protein grafted with polyacrylonitrile fibers, but these m...
