Problems solved by technology

[0002] As a commonly used antibacterial agent, quaternary ammonium salts have good application prospects in enhancing the antibacterial properties of non-woven fabrics. However, due to poor dispersion, quaternary ammonium salts often require more complicated processes to wrap non-woven fabric fibers evenly. This has further hindered the large-scale production and industrial application of quaternary ammonium salts in the antibacterial aspect of non-woven fabrics.

Abstract

The invention provides an antibacterial non-woven fabric as well as a preparation method and application thereof. The method comprises the following steps of providing an aqueous solution of an antibacterial agent; dipping a non-woven fabric base material in the aqueous solution of the antibacterial agent to obtain a dipped base material; and drying the dipped base material to obtain a dried non-woven fabric, wherein the antibacterial agent comprises the following components in percentage by weight of 3%-10% of quaternary ammonium salt, 1%-10% of chitosan microspheres, 3%-4% of a surfactant and 80%-90% of an inorganic solvent; and the antibacterial agent accounts for 10%-60% of the aqueous solution of the antibacterial agent by weight based on 100% of the aqueous solution of the antibacterial agent by weight. The antibacterial non-woven fabric is excellent in antibacterial performance and good in air permeability and has a good application prospect in the aspect of antibacterial protection products.

Description

technical field [0001] The invention relates to the field of materials, in particular to an antibacterial nonwoven fabric and its preparation method and application. Background technique [0002] As a commonly used antibacterial agent, quaternary ammonium salts have good application prospects in enhancing the antibacterial properties of non-woven fabrics. However, due to poor dispersion, quaternary ammonium salts often require more complicated processes to wrap non-woven fabric fibers evenly. This has further hindered the large-scale production and industrial application of quaternary ammonium salts in the antibacterial aspect of non-woven fabrics. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a kind of antibacterial non-woven fabric and its preparation method and application, to improve the coating uniformity and stability of the quaternary ammonium salt antibacterial non-woven fabric material ...
