Problems solved by technology

[0009] The additional special functions of synthetic fiber carpets generally adopt dyeing and finishing methods. For carpets made of polyester fibers, the flame retardants of the usual phosphorus-based flame-retardant finishing will cause adverse effects on the environment during the finishing process. It is mainly reflected in the high cost of cleaning phosphorus-containing sewage, and the effect is not ideal. It will still cause adverse effects of phosphorus enrichment on the natural water system, and the flame-retardant effect is not long-lasting. After repeated washing, the flame-retardant effect will decline.
Phosphorus-based flame-retardant copolyester spinning can make up for the defects of fabric finishing, but the energy consumption of traditional flame-retardant and antibacterial chip spinning or physical blending spinning is significantly higher than that of direct spinning, and the manufacturing cost even exceeds that of post-processing. finishing cost
The antibacterial function of fabrics is reflected in the traditional method of finishing after dyeing and finishing, which will also bring environmental protection pressure to the finishing process, and the relative antibacterial function will be weakened with the cleaning of the fabric. not competitive in terms of sex and manufacturing costs

Abstract

The present invention provides a direct spinning antibacterial and flame-retardant polyester wool type fiber filament bundle, which is prepared from a PET polyester through a direct spinning process, and a zinc based ultrafine powder antibacterial agent with the amount of 1.5-3.0%wt of the polyester, KTPP with the amount of 0.0002-0.0004%wt of the polyester, and a phosphorus-based flame retardant monomer with the amount of 0.3-0.6%wt of the polyester are added. The invention further provides a manufacturing method and a production system of the direct spinning antibacterial and flame-retardant polyester wool type fiber filament bundle. According to the present invention, the direct spinning technology is used to produce the fiber filament bundle, such that the antibacterial property and the flame retardation of the polyester fibers are reinforced, and particularly the desired function is provided after the fiber dyeing and the antistatic finishing; the known textile equipment can be used to produce and treat the fiber filament bundle; and the flame retardation and the antibacterial property can achieve the GB / T14252-2008 standard and the GB / T20944 standard after the fiber filament bundle is subjected to stretch breaking and then the broken fiber filament bundle is prepared into the wool type textile, other physical and mechanical properties are significantly improved compared with the conventional wool-like polyester, the production process is relatively simple, and the continuous production product quality is stable.

Description

technical field [0001] The invention relates to a direct spinning antibacterial and flame-retardant polyester wool filament bundle, a manufacturing method and a production system thereof, and belongs to the technical field of synthetic fibers. Background technique [0002] The research and development and production of antibacterial fibers are produced to meet the needs of the market. There are researches and reports on this aspect at home and abroad. The history of antibacterial fiber textiles is developed from antibacterial finishing technology. As early as in ancient Egypt, people applied antibacterial technology to the preservation of mummies. In 1935, Germany used quaternary ammonium salts to treat military uniforms, which avoided the secondary infection of the wounded. With the development of the times, the rapid development of synthetic fibers, especially polyester fibers, has greatly enriched the market for fibers and textiles. Antibacterial products such as antib...
