Abstract

The invention relates to flame-retardant yarn made of polyphenylene sulfide fibers and aromatic polymer fibers containing sulphone, fabric and garments made of the yarn, and a production method of the yarn, the fabric and the garments. The yarn comprises the polyphenylene sulfide fibers (B) and the aromatic polymer fibers (A) containing sulphone. The aromatic polymer fibers (A) containing sulphone is made of aromatic polymer containing sulphone. The aromatic polymer containing sulphone is polymerized by meta-position aromatic monomer (a) containing diamino, monomer (b) containing sulphone and amino and para-position aromatic monomer (c) containing dicarboxylic acid groups or yl halide (c) of the para-position aromatic monomer. The sulphone accounts for 4-10% in the aromatic polymer. The yarn is good in high temperature resistance and chemical resistance and widely applicable to high-temperature work environments with chemical corrosion.

Description

technical field [0001] The invention relates to a flame-retardant yarn made of sulfone group-containing aromatic polymer fibers and polyphenylene sulfide fibers, fabrics and clothes made therefrom, and their preparation methods. The yarn has good high temperature resistance and chemical resistance at the same time, and can be widely used in high temperature and chemical corrosion working environments. Background technique [0002] In some chemically corrosive working environments, such as chemical wastewater treatment plants, it is necessary to use chemically better materials for chemical liquid filtration. With the improvement of industrial efficiency and the increase of working temperature, the temperature of the processed chemical aqueous solution is getting higher and higher. Accordingly, there is a need for fabrics that are both heat and chemical resistant. [0003] Polyphenylene sulfide (hereinafter referred to as PPS) resin has excellent heat resistance, shielding p...
