Problems solved by technology

[0003] At present, natural cotton antibacterial fabrics that are especially suitable for making close-fitting clothing have not yet formed a mature technology, and the antibacterial function of their products is not stable enough. The main reason is that the antibacterial treatment is inherently insufficient.
The fabric antibacterial treatment process is roughly divided into two types, one is the post-treatment method, that is, the finished fabric is added with an antibacterial agent through the post-treatment process. This method is difficult to maintain the antibacterial effect because the antibacterial factor floats on the surface of the fabric; the other is the cotton yarn Subsequent processing after soaking in antibacterial solution, this method has better antibacterial effect than the former, but the comfort and softness of natural cotton fabrics is damaged to a certain extent

Abstract

The invention discloses a preparation method of an antibacterial cotton fabric. The preparation method comprises the following steps that flos lonicerae, rhizoma coptidis and radix scutellariae are mixed, bamboo charcoal is added, even grinding is conducted, an ethanol solution is added for primary backflow, an extraction solution is collected, medicine residues are subjected to secondary backflowthrough the ethanol solution, the two extraction solutions are mixed, and through concentration, an antibacterial solution is obtained; cotton is evenly sprayed with an antibacterial agent, and through moisture liberation, dewatering and drying, pretreated cotton is obtained; the pretreated cotton and an activated carbon fiber are subjected to opening through an opener and then conveyed into a fiber mixer for sufficient even mixing, carding is conducted for forming yarn, and through spinning, the antibacterial cotton fabric is obtained. The invention further discloses the antibacterial cottonfabric which is prepared by adopting the preparation method of the antibacterial cotton fabric. The antibacterial cotton fabric is good in antibacterial performance and excellent in comfort.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an antibacterial cotton fabric and a preparation method thereof. Background technique [0002] Cotton fabric is porous, loose, and easy to absorb various impurities. It is the carrier of reproduction and parasitic bacteria, and thus becomes one of the main carriers in many bacterial transmission routes. Bacteria and other pathogenic microorganisms are ubiquitous and have been threatening human health for a long time. The bacteria that grow on textiles will use the products of human metabolism-sweat, fat, dander, etc.-as nutrition and multiply rapidly. The existence of these bacteria Not only will the fabric be stained and damaged, but more importantly, it will increase the cross-infection rate in the public environment, and will cause discoloration, mildew, embrittlement and degradation of fiber products, and it will also produce abnormal irritation to human skin and induce vari...
