Antibacterial anti-mite polyester fiber and preparation method thereof

Abstract

The invention provides an antibacterial anti-mite polyester fiber and a preparation method thereof. The antibacterial anti-mite polyester fiber comprises the following raw materials in parts by weight: 75-90 parts of polyester chips and 10-25 parts of antibacterial anti-mite master batches, wherein the antibacterial anti-mite master batches comprise the following raw materials in parts by weight: 80-95 parts of polyester chips, 5-15 parts of nano far infrared powder, 0.5-2 parts of aluminic acid ester coupling agents, 0.5-2 parts of stearic acid, 0.05-1 part of tris-(2,4-di-tert-butyl-pheny)-phosphite and 0.05-1 part of pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate). The antibacterial anti-mite polyester fiber disclosed by the invention adopting a silver ion antibacterial anti-mite material has high-efficiency antibacterial and anti-mite effects. Moreover, due to the surface treatment, the antibacterial and anti-mite material has excellent effect of dispersing in a polyester matrix, so that the production operation is simple and convenient, and industrial production is promoted.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to an antibacterial and anti-mite polyester fiber and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET), also known as polyester Polyethyene terephthalate, is a polymer compound that is prepared by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). The technology of PET polyester spinning is known and common polyester fibers are abundantly available on the market. Due to the continuous deterioration of human survival and living environment, the growth, reproduction, accumulation, fission and other events of harmful bacteria are increasing, so that the continuous upgrading of drugs cannot keep up. Our antibacterial and anti-mite products mainly follow the concept of pre-killing, prevention and control of bacterial growth and reproduction during the event, the concept of reducing the accumulation and...

Problems solved by technology

[0003] The current antibacterial and anti-mite fibers mainly adopt the post-processing type. The post-finishing process is generally to disperse the anti-bacterial and anti-mite powder in the liquid, and then attach it to the surface of the polyester fiber through a coupling agent. This product has many defects: First of all, the antibacterial and anti-mite effect is unstable due to the limited active ingredients of the surface coating; secondly, the durability and washing resistance are poor; the finishing process also increases the uncertainty of the use of post-spinning auxiliaries
