Problems solved by technology

[0005] Embedding silver nanoparticles into fibers during melt spinning is a relatively simple industrial production method for antibacterial fibers, but the polarity of PET is low, and silver nanoparticles without surface modification have poor compatibility with PET, which is easy to agglomerate and affects The performance of its antibacterial rate and antibacterial durability in polyester materials
For example, the Chinese invention with the publication number CN1789502A discloses a nanocomposite antibacterial polyester POY blending high-speed spinning method. The masterbatch is added to the spinning polyester resin in an amount of 3-7% for melt spinning to obtain antibacterial polyester fibers. The disadvantage of this method is that it is difficult to achieve good dispersion of antibacterial powder in polyester resin, a

Abstract

The invention belongs to the field of textile, and particularly relates to antibacterial polyester fibers, which are prepared by melting-spinning the following materials in parts by weight: 100 parts of PET (polyethylene terephthalate) polyester chips and 2 to 5 parts of antibacterial polyester masterbatches, wherein the antibacterial polyester masterbatches are prepared by melt-blending and extruding the PET polyester chips, and 2 to 5 percent of a pre-treatment nanometer silver antibacterial agent, 2 to 3 percent of an antioxidant, 0.1 to 2 percent of a lubricant and 1 to 3 percent of a dispersant, which are counted based on the weight of the PET polyester chips; the pre-treatment nanometer silver antibacterial agent is a nanometer silver antibacterial agent obtained by wrapping treatment with polyethylene wax. According to the antibacterial polyester fibers, the small particle size uniform distribution of the nanometer silver antibacterial agent in a PET matrix is realized, the antibacterial polyester fibers are prepared by melt-spinning, and are efficient and long in service life, and the method is simple, easy and suitable for industrial popularization and application.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to an antibacterial polyester fiber and a preparation method thereof. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has certain special functions in addition to the physical and mechanical properties of ordinary fibers. Radiation, antistatic, anti-ultraviolet, etc.); heat and humidity comfort function (heat absorption, heat release, moisture absorption, moisture release, etc.); medical and environmental protection functions (biocompatibility and biodegradabil...
