Problems solved by technology

However, the currently researched polymers are mainly synthetic fibers such as PVC and polyacrylonitrile. The breaking strength and elongation of the composite fibers spun by them are not ideal, and the skin-friendly, air permeability and hygroscopicity are poor.
[0004] Chinese invention patent CN104862818A discloses a method for preparing keratin composite fibers. It mixes dry keratin powder, fiber-forming polymers, ionic liquids, etc., and mechanically stirs and dissolves at a certain temperature to obtain a keratin composite solution. The keratin composite fiber is prepared by the silk process, and the strength and elongation at break of the composite fiber are greatly improved compared with the pure keratin fiber, but the fiber-forming high polymer is a chemical synthetic fiber, which pollutes the environment and has poor air permeability and skin-friendly effect. Poor, general elasticity
Chinese invention patent CN105002591B discloses a method for preparing composite fibers for hair with quail feathers. The method uses quail feather protein, sodium alginate and polyvinyl alcohol as raw materials to prepare artificial wigs by wet spinning. The artificial wig fibers have Excellent flame retardancy, heat resistance, high strength, soft hand feeling and good gloss, but the artificial wig has poor toughness, easy breakage and poor coloring effect

[0032] The preparation method of the pig hair keratin solution in the present invention is as follows: the pig hair is cleaned, impurity-removed and dried, then pulverized, and then mixed evenly with 0.5 mol / L tributyl phosphine solution, and the temperature is raised to 60-70°C , stirred and reacted for 2-3h, then dropped into NaOH solution to adjust the pH value to 7.5-8.5, and then centrifuged to remove solid impurities to obtain a pure pig hair protein solution. The protein with a molecular weight cut-off of dialysis bag of 5000-10000 was selected to make The protein content in the pig hair protein solution reaches 8-12%, and the required pig hair keratin solution is obtained. Wherein, the solute mass of the tributyl phosphine solution is 5-8% of the dry weight of pig hair after pulverization.

Abstract

The invention discloses a composite fiber material for a wig and a preparation method of the composite fiber material, and relates to the field of wig manufacturing raw materials. The invention discloses the composite fiber material for a wig. The composite fiber material is prepared from the following raw materials in parts by weight of 30-45 parts of poly (adipic acid) / butylene terephthalate, 60-80 parts of montmorillonite / sodium alginate modified liquid, 10-25 parts of a hair keratin solution, 2-3 parts of a cross-linking agent, 5-8 parts of a nonionic surfactant and a proper amount of coagulating bath. A preparation method of the composite fiber material comprises the following steps of preparing grafted PBAT; preparing modified keratin; mixing the grafted PBAT solution, the modified keratin, the nonionic surfactant and water, and spinning; and post-processing the composite fiber to obtain the composite fiber material for the wig. The composite fiber material for the wig is wide in raw material source, environmentally friendly, relatively low in cost, excellent in strength, toughness, air permeability and skin friendliness, soft and smooth in hand feeling, good in coloring effect and good in flame retardance.

Description

technical field [0001] The invention belongs to the field of raw materials for making wigs, and in particular relates to a composite fiber material for wigs and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, wig products are becoming more and more popular. At present, the raw materials for making wigs on the market are mostly chemical synthetic fibers. Because they are not restricted by resources, they have been industrialized and have low cost and cheap price. The mainstream of the hair products market. Synthetic fibers commonly used in wigs include PVC fibers, polyacrylonitrile fibers, polyester fibers, polypropylene-based fibers, and protein fibers. Although these synthetic fibers have good elasticity, smoothness, and bright color, their skin-friendly properties , Air permeability and moisture absorption are poor, and there is still a big gap with natural human hair. In addition, most of the synthetic fiber...
