Problems solved by technology

[0003] In order to increase the antibacterial properties of the existing non-woven fabrics, silver ions or antibacterial agents are added to it to improve the antibacterial agents. Although the antibacterial properties have been improved, the weatherability and aging resistance cannot be solved. At the same time, the mechanical properties are corresponding is poor, so further improvement is still needed
[0004] Chinese patent document (publication number: CN108978038A) discloses a preparation method of a new type of non-woven fabric with antibacterial effect, including the following steps: (1), preparation of modified nano titanium dioxide; (2), spinning; (3) , opening; (4), carding; (5), laying the net, although the antibacterial properties of the non-woven fabric have been improved, but the strength and other properties are poor
[0005] For example, the Chinese patent document (publication number: CN105398161B) discloses a high-strength, durable and environmentally friendly non-woven fabric, including a base layer and two anti-static and waterproof composite layers, and the base layer is arranged between the two anti-static and waterproof composite layers. , wherein the base layer includes 60-70 parts of polylactic acid by weight, and the antistatic and waterproof composite layer includes 70-90 parts of polylactic acid. Although the non-woven fabric has high strength properties, it is antibacterial The performance is poor, and the antibacterial agent added to improve the antibacterial property will affect the strength performance, so the coordination of antibacterial property and strength performance is the focus of the present invention's research and development

Abstract

The invention discloses a preparation method of high strength antibacterial non-woven fabric. The method comprises the following steps: step one, adding 50 to 60 parts of polypropylene into a calcining furnace, increasing the temperature to 220 to 280 DEG C till polypropylene is completely molten, adding 10 to 20 parts of modified liquid, increasing the stirring rotate speed to 200 to 300r/min, stirring for 10 to 20min, then adding 5 to 10 parts of rice hull powder, and 1 to 4 parts of polytriazole resin, continuously stirring for 20 to 30min, and then adding 2 to 4 parts of lignin. The methodhas the advantages that polypropylene is taken as a base material, hemicellulose has excellent oxygen barrier property and oil resistance, methylcellulose has excellent mechanical property, the hemicellulose and the methylcellulose are cross-linked, the added nanometer titanium dioxide is taken as an antibacterial agent, and formed crosslinking modified liquid has tough and soft properties.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a preparation method of high-strength antibacterial non-woven fabrics. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabric has moisture-proof, breathable, flexible, light weight, non-combustible, easy Decomposition, non-toxic and non-irritating, rich in color, low in price, recyclable and so on. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing; non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, and beautiful. There are various patterns and styles, and they are lightweight, environmentally friendly, and recyclable. They are i...
