Abstract

The invention relates to flame-retardant yarn made of polyphenylene sulfide fibers and blended fibers based on aromatic polyamide and Astrel 360, fabric and garments made of the yarn, and production method of the yarn, the fabric and the garments. The yarn comprises the polyphenylene sulfide fibers (A) and blended fibers (B) based on aromatic polyamide and Astrel 360. The blended fibers comprises 40-98wt% of aromatic polyamide and 2-60wt% of Astrel 360, and the aromatic polyamide and the Astrel 360 are blended. The yarn is excellent in high temperature resistance and chemical resistance and widely applicable to high-temperature work environments with chemical corrosion.

Description

technical field [0001] The present invention relates to a flame-retardant yarn comprising a blend fiber based on aromatic polyamide and polyarylsulfone and polyphenylene sulfide fiber, fabrics and garments made therefrom, and their preparation method . 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 hea...
