Problems solved by technology

The flame retardancy of PLA is poor, its limiting oxygen index (LOI) is only about 20%, and its degradation products are mostly flammable gases
In addition, PLA will undergo rapid melting after burning, resulting in melt dripping, causing secondary damage, increasing casualties and economic losses

Abstract

The invention provides a PLA-based degradable antibacterial flame-retardant wig fiber, and relates to the technical field of fibers for simulated wigs. The wig fiber is prepared from the following components in percentage by weight of 80-95 percent of PLA, 2-10 percent of composite flame retardant, 1.5-5 percent of a composite antibacterial agent, 0.4-0.8 percent of toner and pigment, 0.5-1.7 percent of an additive, 0.4-1.8 percent of a dispersing agent and 0.2-0.7 percent of a plasticizer. The composite flame retardant comprises brominated epoxy resin, antimonous oxide, polyphosphoric acid ammonia and hexaphenoxy cyclophosphazene, and the composite flame retardant can ensure that the wig fiber still has the excellent flame retardant property while reducing the addition amount of the brominated epoxy resin, so that the anti-dripping effect of the wig fiber is enhanced. The composite antibacterial agent comprises a nano-silver antibacterial agent, tea polyphenol and triclocarban, and the antibacterial rates of the wig fiber to staphylococcus aureus, escherichia coli and candida albicans can reach 98% or above through reasonable proportioning and common compounding, so that the wig fiber has excellent antibacterial performance; and the wig fiber has the advantages of being environmentally friendly, degradable, antibacterial, flame-retardant, anti-dripping and the like.

Description

technical field [0001] The invention relates to the technical field of artificial wigs, in particular to a PLA-based degradable antibacterial and flame-retardant wig fiber and a preparation method thereof. Background technique [0002] The raw materials of wigs generally come from natural human hair and artificial artificial wig fibers. Due to the scarcity of natural human hair resources, artificial artificial wig fibers are widely used as a substitute for natural human hair at home and abroad. At present, the existing artificial artificial wig fibers are mainly made of polypropylene, polyvinyl chloride, polyester, etc., and the preparation process is complicated. Time creates a lot of buildup. The existing treatment method is incineration activation, but this method will release greenhouse gases and toxic gases, which is not conducive to human health and environmental development. [0003] Biodegradable materials generally refer to polymer materials that can eventually de...
