Antibacterial non-woven fabric and preparation method thereof

Abstract

The invention provides an antibacterial non-woven fabric and a preparation method thereof. Both the upper surface and the lower surface of the antibacterial non-woven fabric are provided with antibacterial film-forming agent layers; each antibacterial film-forming agent layer is obtained by thermally curing a polymer film-forming agent; the polymer film-forming agent has the viscosity of 50-20,000cp and the solid content of 5-55 percent; the film-forming agent has the fluid rate of 2-20 percent; and the polymer film-forming agent is prepared from the following raw materials in percentage by mass: 80-94 percent of a high polymer emulsion, 1-10 percent of a bacteriostatic agent and 5-10 percent of an addition agent. The polymer film-forming agent is selectively roller-coated on the non-woven fabric after the non-woven fabric is formed, so that an antibacterial effect of the non-woven fabric is improved, the antibacterial time is prolonged, and the really long-term antibacterial purpose is achieved.

Description

technical field [0001] The invention belongs to the field of non-woven fabric manufacturing, and in particular relates to an antibacterial non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. Polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because it has the appearance and certain properties of cloth. Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. , it is not made of yarns interwoven and knitted to...

Problems solved by technology

[0004] At present, the market is generally pre-finishing technology. Patent 200610146972.7 discloses a silver fiber antibacterial non-woven fabric. It uses silver fiber as the antibacterial fiber. It will cause the material to oxidize and turn black, and it is easy to fail in the stability test, and the antibacterial effect cannot be achieved.
