Abstract

The invention relates to a clothing fabric based on a one-dimensional nanometer zinc oxide polyester antibacterial masterbatch, belonging to the technical field of high-tech functional composite materials. Polyester resin which is prepared by blending the polyester antibacterial masterbatch in proportion is subjected to conventional pre-crystallization, drying and melt spinning successively to prepare antibacterial polyester fibers, and the antibacterial polyester fibers are woven or are blended and interwoven with cotton, hemp and other chemical fibers to form an antibacterial fabric; and theantibacterial fabric undergoes printing, dyeing and finishing so as to prepare the clothing fabric with antibacterial functions. According to the invention, one-dimensional nanometer zinc oxide is fully and effectively dispersed, so the one-dimensional nanometer zinc oxide is prevented from failures due to agglomeration and allowed to maintain long-lasting antibacterial effect, and can be effectively applied to the polyester resin. The clothing fabric provided by the invention has the characteristics of broad-spectrum antibacterial performance, high efficiency, durability, washing resistance,excellent performance, safety to the body, no toxicity, no harm, no allergenicity, environment protection performance, etc.

Description

technical field [0001] The invention belongs to the field of high-tech functional composite materials. It specifically relates to a garment fabric based on a one-dimensional nano-zinc oxide polyester antibacterial masterbatch. Background technique [0002] Due to the microporous structure of textiles, the body temperature of the wearer, the moisture emitted by the human body and the metabolites of the skin provide a suitable growth environment for microorganisms, making textiles the most suitable breeding ground for microorganisms such as bacteria and fungi. Bacteria growing on textiles not only cause discoloration, mildew, embrittlement and degradation of fiber products, but also produce abnormal stimulation to human skin and induce various skin diseases, affecting human health. [0003] The production of textiles with antibacterial function is one of the effective ways to protect people from bacteria, so textiles with antibacterial function are more and more popular. [...
