Problems solved by technology

Wigs are generally divided into animal keratin fiber hair and synthetic wigs. Animal keratin wigs generally include human hair, horsetail, horse mane, yak hair, oxtail, etc. Animal keratin wigs are better in simulation, but the production of animal keratin fibers is low. The price is high and the growth cycle is long, which is far from meeting the large demand of the market. With the rapid increase in the demand for hair products at home and abroad, and the strengthening of the awareness of environmental protection in all countries in the world, the processing technology of natural human hair has a great impact on the environment and the environment. The water source is seriously polluted, artificial human hair fiber as a substitute for human hair is the ultimate trend of raw materials for hair products

Abstract

The invention relates to a high temperature resistant nylon fiber for manufacturing wig and a preparation method thereof. The fiber is prepared from the following raw materials in parts by weight: 100parts of PA nylon slice, 1 to 10 parts of additive, 0.1 to 10 parts of pigment, and 0.1 to 5 parts of dispersed wax, wherein the additive is at least one of calcium carbonate, talcum powder, titaniumdioxide, silicon dioxide, diatomite, silica powder, glass bead and mica powder, and the temperature resistant range of the pigment is 180 to 350 DEG C. The preparation method comprises the followingsteps: step a, drying raw materials; step b, carrying out single screw extrusion; step c, cooling nascent fibers; step d, applying oil; and step e, carrying out thermal setting and packaging. The prepared fiber is very smooth and has excellent breathability, good moisture removing performance, and unique and natural luster, which is like the luster of real human hair. Moreover, the environment isnot polluted during the preparation process, and no wastewater or waste is generated.

Description

technical field [0001] The invention relates to the technical field of artificial wig fibers, in particular to a high-temperature-resistant nylon fiber for making wigs and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, wigs have become an important fashion accessory in modern life, and the annual consumption in the world is about 150,000 tons. With the continuous growth of the hair products industry, the proportion of human hair raw materials is getting smaller and smaller, and human hair resources at home and abroad are gradually declining. Therefore, the wig products industry urgently needs to find a new human hair resource substitute. Wigs are generally divided into animal keratin fiber hair and synthetic wigs. Animal keratin wigs generally include human hair, horsetail, horse mane, yak hair, oxtail, etc. Animal keratin wigs are better in simulation, but the production of a...
