Broad-spectrum antibacterial non-woven fabric as well as preparation method and application thereof

Abstract

The invention provides a broad-spectrum 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; impregnating a non-woven fabric base material in the aqueous solution of the antibacterial agent to obtain an impregnated base material; and drying the impregnated base material to obtain the dried non-woven fabric, wherein the antibacterial agent comprises the following components in percentage by weight of 1%-5% of quaternary ammonium salt, 10%-20% of antibacterial peptide, 3%-4% of a surfactant and the balance of an inorganic solvent, and based on the weight of the aqueous solution of the antibacterial agent being 100%, the antibacterial agent accounts for 10%-40% of the weight of the aqueous solution of the antibacterial agent. The antibacterial non-woven fabric disclosed by the invention has a good broad-spectrum antibacterial effect.

Description

technical field [0001] The invention relates to the field of materials, in particular to a broad-spectrum antibacterial nonwoven fabric and its preparation method and application. Background technique [0002] In order to improve the antibacterial performance of non-woven fabric materials, antibacterial substances are usually coated on the surface of non-woven fabric materials in the prior art, and these antibacterial substances include quaternary ammonium salts, chitosan and the like. However, the above-mentioned substances may have problems such as narrow antibacterial spectrum, long-term application to produce bacterial resistance, and lead to infection of other opportunistic bacteria and viruses. Studies have found that antimicrobial peptides can overcome the above shortcomings, but antimicrobial peptides generally have problems such as poor stability, uneven dispersion in aqueous solution, fast molecular sedimentation, and inability to combine well with non-woven fibers...
