Abstract

The invention relates to a flame resistant polyester filament and a production method thereof. The filament is composed of flame retardant PBT slices and SiO2-free polyester slices, wherein the flame resistant PBT slices account for the 10 to 20% of the weight of the flame resistant polyester filament. The flame resistant polyester filament is prepared by melting and weaving flame resistant PBT slices and SiO2-free polyester slices. The flame resistant performance of the flame resistant polyester filament is very good.

Description

【Technical field】 [0001] The invention relates to the technical field of textile production, in particular to a flame-retardant polyester monofilament and a production method thereof. 【Background technique】 [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions— - Polyethylene terephthalate (PET), fibers made by spinning and post-processing. It is the simplest one among the three major synthetic fibers, and the price is relatively cheap. In addition, it has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crisp, easy to wash and quick dry, etc., which is loved by people. Polyester is the world's largest and most widely used syntheti...
