Problems solved by technology

However, the silver-plated layer is prone to the action of sulfide in the air to produce silver sulfide, and a black or yellow film is formed on the surface, which weakens the antibacterial effect of the silver-plated layer and cannot last for a long time.

Abstract

The invention discloses a multipurpose antibacterial non-woven fabric and a production process thereof and belongs to the technical field of fiber products and composite materials. According to the technical scheme, the multipurpose antibacterial non-woven fabric comprises a base fabric layer, and the surface of the base fabric is coated with an antibacterial coating, which is composed of, by weight part, 0.1-0.2 part of natural antibacterial agent, 0.5-1.5 parts of defoaming agent, 1-2 parts of water absorbent, 1-2 parts of dispersing agent, 3-6 parts of binding agent and water as balance. The multipurpose antibacterial non-woven fabric has the advantages of being efficient and durable in antibacterial performance, stable in appearance and free from toxicity and pollution. The invention also discloses the production process of the multipurpose antibacterial non-woven fabric. The production process mainly comprises performing a spunlacing procedure and applying the antibacterial coating. The production process avoids affecting the original features of fibers and damaging the fibers, the produced non-woven fabric has the advantages of high strength, low fluffiness, soft hand feelingand the like, besides, the production process is high in production efficiency and utilization rate of raw materials.

Description

technical field [0001] The invention relates to the technical field of fiber products and composite materials, in particular to a multi-purpose antibacterial non-woven fabric and its production process. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties. It has been widely used in people's lives. However, due to its porous shape and chemical structure of polymer compounds, non-woven fabrics are conducive to the attachment of microorganisms. During human wearing or other forms of contact, non-woven fabrics will be stained with sweat, leather and other human secretions and environmental pollutants. It will cause the reproduction and transmission of pathogenic bacteria, so the research and development of antibacterial functions of non-woven fabrics is of great significance. [0003] The existing Chinese patent application whose authoriza...
