Abstract

The invention discloses a preparation method of an antibacterial cotton fabric, and belongs to the technical field of textile materials. The method comprises the step that a cotton fabric original sample is continuously modified in a Na3CO3 solution, a sulfonated polyaniline and peregal O mixed water solution, a sulfuric softening agent water solution, a copper sulfate water solution and an acetum and zinc powder mixed solution successively, then taken out, washed with a large amount of water and dried at the temperature of 40 DEG C to obtain the antibacterial cotton fabric. The preparation method is convenient to implement, the antibacterial polyester fabric has the broad-spectrum antibacterial property, the good antibacterial effect on staphylococcal aureus, hay bacillus, Escherichia coli and copper chlorine bacillus and the high durability, the antibacterial rate of the single bacterium can reach 93.5-99.2% (according to the FZ / T0102-92 'fabric antibacterial performance test method' testing) after the antibacterial polyester fabric is washed for 50 times, and the antibacterial cotton fabric can be used for the field of clothing and costumes and the industry of textile such as tablecloth, napkins and curtains.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of textile materials, and in particular relates to a preparation method of an antibacterial cotton fabric. [0003] Background technique: [0004] As people pay more and more attention to environmental sanitation and self-health, antibacterial sanitary textiles are gradually favored by consumers. Cotton fabric plays an important role in natural textiles. It can be used not only for clothing, but also for other textiles such as tablecloths and napkins. However, its chemical properties make it easy to deliquesce, so it is easy to breed fungi and microorganisms, so its antibacterial treatment cannot be ignored. At present, the antibacterial properties of cotton fabrics are mainly achieved through finishing methods. With the help of siloxane quaternary ammonium salts, organohalogens and chitosan, etc., cotton fabrics can be finished to a certain extent with antibacterial ability (Lu Guigan et al., "Synth...
