Preparation method of anti-bacteria cotton fabric containing AgO/TiO2 composite

Abstract

The invention discloses a preparation method of an anti-bacteria cotton fabric containing an AgO / TiO2 composite. The preparation method comprises the following steps of: mixing AgO powders and TiO2 powders, and then performing ball milling on the mixed powders in a ball mill to obtain AgO / TiO2 composite anti-bacteria powders; then weighing a surface active agent which is then put into a reactor, adding deionized water in the reactor, then heating the mixed liquid, stirring the mixed liquid to dissolve the surface active agent, then adding the ultrafine AgO / TiO2 composite anti-bacteria powders in the mixed liquid, stirring the liquid continuously, finally adding an adhesive into the liquid, and stirring the liquid to obtain AgO / TiO2 composite anti-bacteria finishing agent suspending liquid; and soaking, washing and drying a cotton fabric, heating and stirring the AgO / TiO2 composite anti-bacteria finishing agent suspending liquid, soaking the cotton fabric into the AgO / TiO2 composite anti-bacteria finishing agent suspending liquid, then washing the cotton fabric by tap water under a room temperature, and drying the cotton fabric to obtain the anti-bacteria fabric containing the AgO / TiO2 composite. The preparation method solves the problems that the conventional preparation method of anti-bacteria fabrics is complex, the sterilizing speed of the fabrics is slow, and the anti-bacteria capability of the fabrics is weak.

Description

technical field

[0001] The invention belongs to the technical field of textiles, and relates to an AgO / TiO-containing 2 The preparation method of composite antibacterial cotton fabric. Background technique

[0002] Textiles are the materials that people come into contact with the most in daily life. In the process of wearing and using, due to factors such as human body metabolism, environmental factors and the textile itself does not have the ability to kill bacteria, textiles are easy to become an important medium for the reproduction and spread of pathogenic bacteria. , induce various skin diseases, and seriously affect human health and quality of life. With the development of society and the improvement of living standards, people pay more and more attention to their health and quality of life, and the existing textiles can no longer meet people's requirements. Therefore, it is of great social significance to perform antibacterial finishing on textiles to endow textiles...
