Description

PCT-based antibacterial flame-retardant artificial wig fiber and preparation method thereof

Technical Field

The invention relates to the technical field of simulation wigs, in particular to an antibacterial flame-retardant simulation wig based on PCT and a preparation method thereof.

Background

In modern life, the wig not only becomes an ornament for pursuing individuation of people, but also provides a good solution for some people with needs, and the demand of the wig is increasing along with the development of cultural industries such as movie and television, drama, cossplay and the like.

At present, artificial wigs mainly made of synthetic material fibers are mainly circulated in the market, and the commonly used wig preparation raw materials comprise wig fibers of PVC, PP, PET and PBT. PVC and PP wig fibers have the defects of poor light and heat stability, easy combustion, toxic combustion products, carcinogenic risk to human bodies and the like in the production and use processes. Although PET and PBT wig fibers have the excellent characteristics of human hair-like and high temperature resistance, the fibers must be curled and formed under the cooling condition in the production and use processes, and are not flame-retardant.

PCT (poly 1, 4-cyclohexanedimethanol terephthalate) is a thermoplastic polyester resin for semi-crystalline high temperature resistant engineering plastics developed on the basis of PET and PBT. Compared with PET and PBT, PCT has better characteristics, higher heat resistance and good strength and toughness under high temperature for a long time; good processing formability; excellent mechanical properties and colorability; excellent chemical resistance; the advantages of low hygroscopicity and the like further become powerful competitors in the raw materials for preparing the wig. Although PCT has natural V2 grade flame retardant properties, in practical applications, a small amount of additional flame retardant is still required to ensure the safety of the fiber.

With the increasing importance on health of people, the antibacterial property of the wig is also required to be higher. At present, few antibacterial wigs are circulated in the market, the types of the added antibacterial agents are single, most of the antibacterial wigs are added with silver ion type antibacterial agents and titanium ion type antibacterial agents, although the antibacterial wigs have a certain antibacterial effect, the manufacturing cost of the silver ion type antibacterial agents and the titanium ion type antibacterial agents is high, the cost of the wigs is increased, and the wigs are not beneficial to development of merchants and use of the merchants.

When the existing PCT antibacterial flame-retardant artificial wig fiber is produced and manufactured, a plurality of processes such as extrusion, heating, heat preservation, stretching and the like are needed, and the extruded nascent fiber can generate a large amount of waste gas at an outlet, so that the environment of a production workshop is polluted, and the physical health of personnel is not facilitated; meanwhile, the primary fiber needs to be cooled when the temperature is too high, and the cooling is carried out by adopting a circular blowing or side blowing process in most of the traditional methods; the cooling temperature is uneven, the temperature of the fibers of the cooled PCT antibacterial flame-retardant simulation wig cannot be detected and identified to meet the production requirements and the like, and the quality of the wig is seriously influenced.
