Abstract

The invention relates to a low-melting-point antibacterial specially-shaped polyester monofilament. The low-melting-point antibacterial specially-shaped polyester monofilament comprises the following raw materials by weight percent: 1 to 5 percent of antibacterial agent, 5 to 25 percent of pigment, 0.5 to 1 percent of dispersing agent, 0.5 to 1 percent of antioxidant and the balance of low-melting-point polyester slices; chitosan is likely to dissolve in weak-acid solvent, particularly the dissolved solution contains amino groups, and the amino groups are combined with negative electrons to inhibit the bacteria. Due to the bacterial inhibition activity of the chitosan, the chitosan is widely applied in the fields such as textiles and the like; the processing technology is simple and easy to popularize and use.

Description

【Technical field】 [0001] The invention relates to the technical field of polyester monofilament, in particular to a low melting point antibacterial special-shaped polyester monofilament and a processing method thereof. 【Background technique】 [0002] Single-component low-melting polyester fibers are generally used in soft and environmentally friendly non-woven fabrics, non-ironing and environmentally friendly fabrics, cables, electronic cables, textile yarns, medical textiles, automotive interior fabrics or building heat and sound insulation materials. Mainly play a thermal bonding role. Compared with chemical adhesives, thermally bonded fibers have the characteristics of reusability, easy bonding, high strength, non-toxic and harmless, low energy consumption, and environmental protection, and can replace chemical adhesives in the application of textile composites , so it is getting more and more attention. With China's emphasis on environmental protection, the steps of re...
