Preparation method of spinning hairpiece by human hair and protein acrylic fibre

Abstract

The invention relates to a preparation method for hairpiece formed by human hair and protein acrylon. The method comprises the following steps: human hairs being crushed into human hair powder at mean diameter of 1-10 micron, wherein the maximum size is not more than 30 micron; the human hair powder uniform distributing in polyacrylonitrile fibre, wherein the content of human hair powder is 1-30%(wt%) and the content of polyacrylonitrile is 70-99%(wt%); using wet-process acrylon spinning technique to finally obtain the protein acrylon hairpiece. The said human hair is crushed, no need of chemical extraction. The operation is simple, the souce of raw materianl is wide and the cost is low. The protein acrylon hairpiece has features of satia plump texture, good hand feeling, reality, similar burning property to human hair.

Description

technical field [0001] The invention belongs to the field of polymer polyacrylonitrile spinning, and in particular relates to a preparation method for spinning wigs from human hair and protein acrylic fiber. Background technique [0002] Artificial hair is an important fashion accessory in modern life, with an annual global consumption of more than 100,000 tons. The production and application of artificial hair abroad began in the 1970s, while in my country it began in the 1990s. So far, the application is still very low, and most of the products produced are for export. Early artificial hair was produced by spinning polyethylene terephthalate, namely PET resin. PET artificial hair has the advantages of low price and crispness, but its color and color are poor in simulation, especially when burning. The melt that melts into moxibustion heat adheres to the skin and causes skin burns; therefore, its application is limited in some places. Polyacrylonitrile artificial hair not...

[0003] Using natural protein to make regenerated protein fiber is an important method for chemical fiber to simulate natural protein fiber. Preparation of protein composite fibers, for example, the Chinese patent application publication number is CN1640336A report, from human hair or animal hair, plant using chemical method to extract natural protein, after being formulated into a solution, and raw materials such as acrylonitrile copolymerized to prepare protein synthetic fiber spinning dope , the final spinning made protein acrylic wig; Chinese patent application publication number is that CN1370859A has also reported the method for the preparation of protein acrylic fiber after the power mixing after similar extracting protein, and Chinese patent application publication number is that CN1431343A has reported a kind of plant protein acrylic fiber Preparation method, the purpose of which is to improve the comfort and dyeing properties of acrylic fibers
