Abstract

The invention relates to an antibacterial non-woven fabric with high barrier performance and a preparation method thereof, and relates to the technical field of non-woven fabrics and the preparation method. The antibacterial nonwoven fabric comprises a nonwoven fabric layer and a barrier coating uniformly coated on the surface of the nonwoven fabric layer, and the nonwoven fabric material of the nonwoven fabric layer consists of the following components by weight: low density polyethylene 50 -60 parts, 6-8 parts of polypropylene, 6-8 parts of polyisobutylene, 10-15 parts of reinforcing modifier; the barrier coating of the barrier coating is composed of the following components by weight: organic montmorillonite 60- 80 parts, epoxy resin 15-25 parts, polyvinyl acetal 15-25 parts, silver powder 1.2-2.5 parts. The preparation process is to prepare the non-woven fabric by hot-melt bonding, and then prepare the barrier coating by coating, so as to obtain the finished non-woven fabric. The invention has the advantages of good antibacterial effect, good barrier effect and high strength.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics and preparation methods, in particular to an antibacterial non-woven fabric with high barrier performance and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have many advantages such as moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. [0003] Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. Because it is a fabric that does not need spinning and weaving, it is just oriented or random arrangement of short textile fibers or filaments to form a web struc...
