Abstract

The invention relates to a preparation method of ultraviolet ray resistant antibacterial fabric. The preparation method comprises the following steps of impregnating fiber fabric in finishing liquid for 10-20min, impregnating and padding twice, drying, baking at 90 DEG C -110 DEG C for 30-90min, soaping, washing, airing and chloridizing to obtain the finished product. The process reaction condition is mild, the reaction time is short, the reaction energy consumption is low, the technological process is simple, and synthesized nano-titanium dioxide has high photocatalytic activity.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a preparation method of three kinds of antibacterial fabrics loaded with haloamine compound / nanometer titanium dioxide and having high ultraviolet stability and high washing stability. Background technique [0002] Microorganisms widely exist in the daily life environment, and textiles are considered to be a good medium for the growth of microorganisms such as bacteria and fungi. Favorable conditions such as humidity, temperature and nutrients (skin secretions) on human skin and textiles in contact with it can make bacteria It reproduces rapidly and decomposes various organic substances, producing unpleasant odors, and even changing the color of textiles and reducing their strength, thereby reducing the appearance quality of textiles. [0003] Currently commonly used organic antibacterial agents include quaternary ammonium salts, quaternary phosphonium salts, and haloa...
