Production method of durable combined antimicrobial non-woven fabric material

Abstract

The invention provides a method for making a durable compound antibiosis nonwoven cloth material. By performing an efficient combination of insoluble silver particle pincer system which has a non dissoluble type high efficient antibiosis function with dissoluble type chlorine system quaternary ammonium salt, an antimicrobial solution with a certain concentration is made, by performing immersing and rolling finishing on the chemical fiber non woven cloth with the antimicrobial, a non woven cloth which combines active antibiosis and passive antibiosis functions is made, the non dissoluble silver pincer complex is a nanometer particle pincer complex of silver carbonate or silver bromide; the quaternary ammonium salt is a CTMAC or a double stearyl DHTDMAC, which has a good surface treating and antibiosis performance; as for the mixture ratio of the two, the former is 10 to 60 percent, the latter is 90 to 40 percent, and as for the optimal mixture ratio, the former is 25 percent and the latter is 75 percent. The after finishing is adding the assembled antimicrobial onto the molded non woven cloth coiled material by immersing and sprinkling, and baking and sizing the material, without any other surface pre-treating process.

Description

Technical field: [0001] The invention belongs to the textile industry and relates to a method for manufacturing a durable composite antibacterial nonwoven material. Background technique: [0002] Since the late 1990s, nonwoven materials have been gradually developed in China. After nearly 20 years of continuous research and improvement, at present, the development and application of domestic nonwoven products have gradually penetrated into various fields. The functional requirements of young materials are also increasing. Only one item of shoemaking materials, the midsole, inner lining, toe lining, heel lining, etc. in each pair of shoes, will have non-woven fabrics. The types of collection include stitching, needle punching, spunbonding Nonwovens and chemical bonding, among shoemaking materials, the annual consumption of nonwovens in the country exceeds 40,000 tons. [0003] While gradually accepting the quality and performance of non-woven fabrics, various application fi...

Problems solved by technology

However, there are still some inconveniences in the finishing of nonwoven fabrics. Firstly, silver nitrate has high reactivity, which is easy to replace with iron equipment parts and loses the antibacterial effect. Second, silver nitrate has high reactivity. Water-soluble, easy to lose in the washing process
