Abstract

The invention discloses a preparation method of antibacterial polyester fabrics and belongs to the technical field of textile materials. The preparation method comprises the following steps: after sequentially carrying out continuous modification treatment on polyester fabric original samples including clothing, tablecloth and curtains by virtue of a Na2CO3 solution, a mixed solution of alizarin red and sodium cyclamate, a mixed solution of aniline, hydrochloride and ammonium persulfate, a mixed solution of DL-mercaptosuccinic acid and D-penicillamine and a nano-silver solution, putting the treated polyester fabric original samples into a silver tetrafluoroborate aqueous solution, carrying out reaction at room temperature for 30 minutes, washing the product by a great deal of water, and drying at the temperature of 40 DEG C to obtain the antibacterial polyester fabrics. The antibacterial polyester fabrics prepared by the preparation method have the broad-spectrum antibacterial property, are good in antibacterial effect particularly on staphylococcus aureus, bacillus subtilis, Escherichia coli and pseudomonas aeruginosa, are strong in persistence and have the single-strain inhibitory rate reaching 95-99.7 percent after being washed for 30 times.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a preparation method of an antibacterial polyester fabric. Background technique: [0002] With the strengthening of people's health awareness, textiles that are beneficial to health and have health care functions are more and more favored by people, and exploring functional textiles has become a research hotspot in the textile industry (Li Zhizhi et al., "Nano silver antibacterial fiber in textile industry application", "Knitting Industry", 2013, 7, 65-66). Whether it is clothing and apparel textiles, or decorative textiles such as tablecloths and curtains, human secretions such as sweat, sebum flakes, oil stains, and traces of food will inevitably adhere to them during use. A good medium (Chinese CN103774265A "An antibacterial fiber and its preparation method"). Therefore, preparing and developing antibacterial fabrics is a problem to be solved urgently ...
