Embodiment 1

[0036] In this example, a non-woven fabric is prepared by the following method, which includes the following steps:

[0037] A composite fiber composed of viscose fiber and biomass graphene is used as the raw material of the non-woven fabric, and the length of the composite fiber is 38 mm.

[0038] Prepare the antibacterial non-woven fabric through the steps of opening, carding, netting, spunlace, drying, and winding, wherein the spunlace step uses a hydrogen peroxide solution containing biomass graphene to spunlace at room temperature and high pressure, The mass percent concentration of biomass graphene in the hydrogen peroxide solution is 1%, the molar solubility of the hydrogen peroxide solution is 3mmol / mL, and the high pressure is a pressure of 2×10 6 Mpa, the mass percent content of biomass graphene in the composite fiber is 2%.

[0039] figure 1 It is a schematic diagram of the fiber structure of the nonwoven fabric prepared in this example.

Embodiment 2

Abstract

The invention provides an antibacterial non-woven fabric and its preparation method and application. The antibacterial non-woven fabric is prepared through the steps of opening, carding, web laying, spunlace, drying and winding, wherein the spunlace The step is to carry out spunlace by using hydrogen peroxide solution. The antibacterial non-woven fabric of the present invention can solve the shortcomings of the existing non-woven fabrics that have poor antibacterial effect, has high-efficiency softness and toughness, fine texture, and strong hydrophilicity. Spunlace can make the contact between graphene material and non-woven fabric fibers closer under normal temperature and high pressure. Under high pressure, graphene material is hit into the inside of the fiber, and the combination is firm, further improving the mechanical properties of non-woven fabrics, increasing air permeability and water absorption. , and the oxidation and antibacterial combination of graphene and hydrogen peroxide improves the antibacterial effect of non-woven fabrics, improves the softness and toughness of non-woven fabrics, and can promote skin surface microcirculation, which can be used in 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,...
