Problems solved by technology

Since the sulfur in the molecular structure of PPS is negative divalent, it is easy to lose electrons and combine with oxygen, resulting in degradation and macromolecule breakage. Therefore, the oxidation resistance of PPS, especially the thermal oxidation resistance, is poor, resulting in the overall deterioration of the yarn. Insufficient thermal oxygen resistance

Embodiment 1

[0071]70wt% 1.5D*51mm modified polyphenylene sulfide fiber (modified by method 2), 10wt% 2D*51mm para-aramid staple fiber, 20wt% 50D glass fiber filament were cleaned by ring spinning machine Cottoning, carding, drawing, roving, spinning, and winding processes to produce core-spun single yarns with a count of 20S / 1 and a twist of 45 twists / 10cm, and plying to obtain 20S / 2 twists of 30 twists / 10cm Ply yarn. Two 20S / 2 yarns and one 20S / 1 yarn were used to weave gloves on a 10-needle glove machine, and the glove weight was 31.2g / piece.

Embodiment 2

[0073] 70wt% 2D*51mm modified polyphenylene sulfide fiber (modified by method 2), 10wt% 3D*51mm para-aramid staple fiber, 20wt% 100D glass fiber filament, are cleaned by ring spinning frame , carding, drawing, roving, spun yarn, and winding process to produce a core-spun single yarn with a count of 10S / 1 and a twist of 45 twists / 10cm, and a ply of 10S / 2 with a twist of 30 twists / 10cm yarn. One 10S / 2 yarn and one 10S / 1 yarn were used to weave gloves on a 10-needle glove machine, and the glove weight was 32.5g / piece.

Embodiment 3

[0075] 50wt% 1.5D*51mm modified polyphenylene sulfide fibers, 10wt% 4D*51mm para-aramid staple fibers, 40wt% 200D glass fiber filaments are cleaned, carded and drawn on a ring spinning frame , roving, spun yarn, and winding process to produce a core-spun single yarn with a count of 10S / 1 and a twist of 45 twists / 10cm, and a plied yarn with a twist of 10S / 2 and a twist of 30 twists / 10cm. One 10S / 2 yarn and one 10S / 1 yarn were used to weave gloves on a 10-needle glove machine, and the glove weight was 30.2g / piece.

Abstract

The present invention relates to a modified polyphenylene sulfide based flame-retardant anti-cutting yarn. The yarn comprises the following components in percentage by mass: 20-80% of modified polyphenylene sulfide fibers, 5-40% of flame-retardant fibers and 5-40% of cutting reinforced filaments; and the modified polyphenylene sulfide fibers are polyphenylene sulfide fibers subjected to oxidationmodification, part or all of sulfur atoms in a polyphenylene sulfide structure are oxidized into sulfonyls or sulfoxide groups by oxidation modification, and the modified polyphenylene sulfide fibershave the characteristics of no melting under the high temperature, no melting shrinkage, instant quenching away from fire and the like. Protective gloves prepared from the yarn have ideal cut resistance and flame-retardant protection performance, the wearing comfort of the flame-retardant anti-cutting gloves is improved, and the cost is lower. In the field of labor protection gloves, compared witharamid fibers, the flame-retardant anti-cutting yarn has a certain advantage of substitutability.

Description

technical field [0001] The invention relates to the technical field of textile protective products, in particular to a modified polyphenylene sulfide-based flame-retardant and cut-resistant yarn, a preparation method and gloves. Background technique [0002] According to preliminary surveys, the demand for flame-retardant and cut-resistant gloves is increasing year by year. At present, flame-retardant and cut-resistant gloves are generally woven from aramid fiber. Aramid fiber has the characteristics of ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and intrinsic flame retardancy, which can meet the requirements of the market to a certain extent. The demand for flame-resistant cut protective gloves. However, due to the disadvantages of aramid fibers such as discoloration when exposed to light, difficult dyeing, high modulus, high rigidity (not soft enough) and high price, the labor protection gloves prepared from it have disadvan...
