Abstract

The invention belongs to the technical field of antibacterial materials, and discloses a non-dissolution type long-acting antibacterial protective non-woven fabric and a preparation method and application thereof. The preparation method comprises the following steps that antibacterial liquid is evenly sprayed on a non-woven fabric or the non-woven fabric is soaked in the antibacterial liquid, andorganic silicon molecular polymerization is carried out to enhance the binding force of non-woven fabric fiber and antibacterial active substances; and high-temperature setting is performed, and the antibacterial active substances such as ammonium salt and nano-silver are loaded on the surface of the non-woven fabric in a directional mode to prepare the antibacterial protective non-woven fabric, wherein the antibacterial liquid comprises nano-silver gel, quaternary ammonium salt, organic silicon, an auxiliary agent and water. According to the method, the high-activity quaternary ammonium saltand the nano-silver are loaded on the surface of the non-woven fabric fiber to form an ultra-thin positively charged antibacterial layer through chemical bonding of the organic silicon on the surfaceof the polymer fiber, the structure of the non-woven fabric fiber is basically not damaged, the good air permeability is maintained, meanwhile, the rejection rate of the protective non-woven fabric can be remarkably improved, and masks prepared from the non-woven fabric can be repeatedly used.

Description

technical field

[0001] The invention belongs to the technical field of antibacterial materials, and in particular relates to the preparation of a non-dissolving long-acting antibacterial protective non-woven fabric and its application in protective masks. Background technique

[0002] Non-woven fabrics, also known as non-woven fabrics, use short fibers or filaments to be oriented or randomly arranged to form a fiber network structure, and then reinforced by mechanical, thermal bonding or chemical methods to obtain non-woven fabrics. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable, so they are widely used in medical and health, family clothing and other industries . Among them, in the medical and health industry, medical consumables such as disposable masks, protective clothing, surgical gowns, isolation gowns, lab co...
