Embodiment 1

[0009] A certain amount of acrylonitrile copolymer spinning stock solution using sodium thiocyanate aqueous solution as solvent is prepared by a generally known method. The composition of the acrylonitrile copolymer is: 91.5% of acrylonitrile, 7.0% of methyl acrylate, and 1.5% of sodium methacrylate. In the spinning stock solution, the concentration of acrylonitrile copolymer is 13%, and the concentration of sodium thiocyanate is around 45%, and the amount of 5% of the acrylonitrile copolymer in the superfine human hair powder and the spinning stock solution is mixed with the above-mentioned spinning stock solution at 65° C. Stir and mix for 2-3 hours, press filter to remove too coarse particles, and then degas to obtain a mixed spinning stock solution; use 13% sodium thiocyanate aqueous solution as a coagulation bath, and process the above mixed spinning stock solution according to a conventional method. The protein acrylic fiber wig is obtained after spinning, solidifying, w...

Embodiment 2

[0011] A kind of spinning of flame-retardant modified polyester type wig fiber, this spinning comprises following components, and each component is distributed by weight, such as as follows:

[0012] Bromine-containing flame retardants are compounds with a bromine content higher than 60% (by molecular weight), in which bromine plays a role in flame retardancy. Processing aids are used to lubricate and disperse raw materials. PET has good rigidity, the glass transition temperature is about 81°C, and the price is cheap. PBT has good toughness, but its glass transition temperature is low (only about 30°C), and its price is high. The above ratio of PET and PBT makes the product cost-effective, the performance of the wig fiber is good, and the heat setting is easy. A manufacturing method of the above-mentioned spinning, the manufacturing method includes the following steps: making PET and PBT raw materials at a temperature of 150 ° C Dry for 4 hours, so that the moisture content ...

[0014] A kind of spinning of flame-retardant modified polyester type wig fiber, this spinning comprises following components, and each component is proportioned as follows by weight:

[0015] Bromine-containing flame retardants are compounds with a bromine content higher than 60% (by molecular weight), in which bromine plays a role in flame retardancy. Processing aids are used to lubricate and disperse raw materials. PET has good rigidity, the glass transition temperature is about 81°C, and the price is cheap. PBT has good toughness, but its glass transition temperature is low (only about 30°C), and its price is high. The above ratio of PET and PBT makes the product cost-effective, the performance of the wig fiber is good, and the heat setting is easy. A manufacturing method of the above-mentioned spinning, the manufacturing method includes the following steps: making PET and PBT raw materials at a temperature of 160 ° C Dry for 5 hours, so that the moisture content in PET a...

Abstract

The invention discloses wig with good hand feeling and a preparation method thereof. The method comprises the following steps of crushing human hair into human hair powder with the average particle diameter being 1 to 10 micrometers and the maximum particle diameter not exceeding 30 micrometers; then, uniformly distrusting the human hair powder into polyacrylonitrile fiber, wherein the content ofthe human hair powder is 1 to 30 weight percent; the content of polyacrylonitrile fiber is 70 to 99 weight percent. A wet process acrylic spinning technology is used for obtaining protein acrylic wighair. The ingredients comprise PET, PBT, bromine-containing flame retardants, antimony-containing flame retardant synergists and processing auxiliary agents. The method has the advantages that the wigis prepared from human hair through being crushed; the chemical extraction is not needed; the operation is simple and convenient; the raw material sources are wide; the price is low; the protein acrylic wig hair has the characteristics that the texture is full; the hand feeling is good; the vivid effect is achieved; the combustion properties are similar to that of the human hair.

Description

technical field [0001] The invention relates to a synthetic fiber and its manufacturing technology, in particular to a wig with good hand feeling and its preparation method. 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 only has the advantages of full t...
