Problems solved by technology

If these hairs cannot fall off in time during continuous wearing, they will be entangled with each other and kneaded into many small spherical particles, which will cause the fabric made of polyester filament to be prone to pilling.

Embodiment 1

[0051] A kind of high wear-resistant DTY, the concrete component that comprises and weight are as shown in table 2, are made by following steps:

[0052] S1: Mix and stir the anti-pilling agent, silicon carbide, anti-wear agent, and polyvinylpyrrolidone at a stirring speed of 1000r / min, and obtain the first mixture after stirring evenly; mix amino silicone oil, chitosan, penetrant and deionized water Mixing and stirring, the stirring speed is 800r / min, and the finishing agent is obtained after stirring evenly.

[0053] S2: Mix and stir the polyester chip, diphenylsilanediol and the first mixture at a stirring speed of 800r / min. After stirring evenly, perform melt extrusion. The melt extrusion temperature is divided into six regions, each of which is 256°C -258°C-260°C-262°C-264°C-266°C, the pressure is 50MPa, and then filtered with a 30-mesh metal mesh; after filtration, spinning is carried out at a spinning temperature of 265°C and a spinning speed of 800m / min; Finally, it i...

Abstract

The invention relates to the technical field of textiles, and particularly discloses high-wear-resistance DTY and a preparation method thereof. The high-wear-resistance DTY is prepared from the following raw materials in parts by weight of 80-95 parts of polyester chips, 2-5 parts of an anti-pilling agent, 0.5-0.8 part of diphenyl silandiol, 0.8-2 parts of silicon carbide, 1-2 parts of a wear-resistant agent, and 0.8-1.6 parts of polyvinylpyrrolidone. The anti-pilling agent is prepared from wheat straw powder and sodium alginate, and the weight ratio of the wheat straw powder to the sodium alginate is 1: (1-1.5). The preparation method comprises the following steps of uniformly mixing the anti-pilling agent, the silicon carbide, the wear-resistant agent, the polyvinylpyrrolidone and a reinforcing agent to obtain a first mixture; uniformly mixing the polyester chips, the diphenyl silandiol and the first mixture, and performing melt extrusion, filtration, spinning, cooling, stretching and false twisting, and winding to obtain filaments; and spraying the filaments with a finishing agent, standing for 30-60 minutes, performing rinsing with deionized water, and performing drying to obtain the high-wear-resistance DTY. The high-wear-resistance DTY disclosed by the invention has the advantage of pilling resistance.

Description

technical field [0001] The application relates to the field of textile technology, in particular to a high wear-resistant DTY and a preparation method thereof. Background technique [0002] DTY is a stretched textured yarn, which is a finished yarn that is stretched continuously or simultaneously on a texturing machine and deformed by a twister; currently commonly used polyester DTY is made of polyester chips, which are spun at high speed to produce polyester prefabricated yarns. Oriented yarn is processed by drawing and false twisting. It has the advantages of good wear resistance and comfortable hand feeling, and is widely used in the textile field. [0003] Polyester fabrics made of polyester filaments, due to the relatively small cohesion between fibers, high fiber strength, and particularly large elongation, the fibers are constantly subjected to external friction, so that the fibers on the surface of the fabric are continuously exposed to the fabric. There are many ha...
