Abstract

The invention provides antibacterial non-woven fabric and a preparation method and applications thereof. The antibacterial non-woven fabric is obtained by opening, carding, lapping, spunlacing, dryingand winding, wherein a hydrogen peroxide solution is adopted in the spunlacing step. The antibacterial non-woven fabric of the invention can solve the disadvantage that the antibacterial effect of the existing non-woven fabric is not good, which has highly effective skin softness and toughness, fine texture and strong hydrophilicity; the use of hydrogen peroxide containing graphene material for spunlacing makes the contact between graphene material and non-woven fabric fiber at room temperature and high pressure more tight. The graphene material is struck inside the fiber under high pressure,and the bonding is firm, further improving the mechanical properties of the non-woven fabric, improving the air permeability and the water absorption rate. The oxidative antibacterial combination ofgraphene and hydrogen peroxide improves the antibacterial effect of the non-woven fabric, improves the softness and toughness of the non-woven fabric, and promotes microcirculation of the skin surface. The method can be used for the preparation of various textiles.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and relates to an antibacterial nonwoven fabric, a preparation method and application thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating. There are applications, among which, non-woven fabrics are used as the base material of facial masks, wet wipes and medical and sanitary products, which require higher water absorption and better toughness in wet state. For these more high-end products, not only must Good air permeability, but also has a good antibacterial effect. [0003] CN103437065A discloses a kind of non-woven fabric of high-permeable facial mask and its manufacture method. It adopts cellulose staple fiber as raw material,...
