Polyester-cotton composite fabric with antibacterial and impermeable functions and preparation method thereof

Abstract

The invention discloses a polyester-cotton composite fabric with antibacterial and impermeable functions. The polyester-cotton composite fabric comprises polyester fiber capable of releasing an antibacterial agent continuously, double-layer close-twill polyester-cotton base cloth, and an impermeable finishing layer with a fluorinated compound on the surface of the base cloth. After being finished by the fluorinated compound on the surface, the inorganic antibacterial agent can diffuse to the surface of the finishing layer and perform the antibacterial function continuously, loss of the antibacterial agent in the cleaning process can be avoided, and the antibacterial life of a protective garment can be prolonged. By adopting polyester-cotton blended fabric as the base cloth material of the protective garment, the wearing comfort is improved, and the high strength, breathability and wrinkle resistance of polyester are improved. By adopting the double-layer twill polyester-cotton base cloth, the antibacterial performance and the impermeable performance can be improved with the advantages of the weave structure on the basis of the same textile materials. The surface layer modified with the fluorinated compound NUVA HPC LIQ has low surface energy, interstitial fluid such as water, oil, blood and alcohol can be effectively prevented from adhering to or permeating into the surface of the protective garment, and cleaning is convenient.

Description

technical field [0001] The invention relates to a fabric, in particular to a polyester-cotton composite fabric with antibacterial and anti-permeation functions, which belongs to the field of textile fabrics. Background technique [0002] Functional textiles are the fastest growing product in the global textile industry, and medical textiles are one of the most dynamic industries in the functional textile industry. With the development of society and the strengthening of people's health awareness, people's attention to protective textiles has also increased significantly. This invention relates to the antibacterial and anti-permeation aspects of medical textiles, and aims to propose a new method for processing antibacterial and anti-permeation fabrics. train of thought. [0003] Antibacterial is the general term for antibacterial and bactericidal effects. At present, there are two main methods for the preparation of antibacterial fabrics: first, it is prepared from fibers w...

AI Technical Summary

Problems solved by technology

The main varieties of organic antibacterial agents are vanillin or ethyl vanillin compounds, which have poor heat resistance and short validity period due to hydrolysis; natural antibacterial agents are mainly extracted from natural plants, such as chitin, mustard castor oil, etc., but have poor heat resistance. The antibacterial effect is limited; inorganic antibacterial agents are mainly metal ions, which can be fixed on the surface of zeolite, silica gel and other porous materials by physical adsorption ion exchange and other methods to make antibacterial agents, and then added to corresponding products
