Problems solved by technology

[0004] However, although the cotton fabric loaded with haloamine antibacterial agent has excellent antibacterial performance, the haloamine compound itself and its N-Cl bond have poor UV stability, and are prone to breakage under ultraviolet irradiation, which makes the antibacterial property of the fabric drop sharply, and the maintenance time Shorter, poor UV stability; in addition, due to the acidic effect of the cross-linking agent and high-temperature baking during the finishing process, the cotton fiber is prone to hydrolysis and degradation, the degree of polymerization decreases, and the tensile breaking strength of the fabric is significantly reduced, which seriously affects the wearability of the fabric. performance

Abstract

The invention discloses a preparation method of a dihydroxy halamine compound / Nano-TiO2 ultraviolet-resistant antibacterial cotton fabric. The preparation method comprises the following steps of: soaking a cotton fabric into a finishing solution; drying the cotton fabric which is soaked and rolled twice; baking the dried fabric for 90-180 seconds at 150-180 DEG C; and soaping, washing, airing and chlorinating the baked fabric to prepare the finished product. A preparation method of the finishing solution comprises the following steps of: adding mano-TiO2 with the final concentration of 1wt%-5wt% into water; stirring and ultrasonically vibrating water and nano-TiO2; then adding a nonionic surfactant with the final concentration of 0.5g / L -1.5g / L, butanetetracarboxylic acid with the final concentration of 4wt%-7wt% and sodium hypophosphite with the final concentration of 5wt%-10wt% to the obtained solution; ultrasonically vibrating the substances and the solution; and finally adding 3-(2,3-propanediol)-5,5-dimethylimidazolidinyl-2,4-dione with the final concentration of 3wt%-8wt% to the mixed solution to obtain the finishing solution. The preparation method is simple in process, and the prepared antibacterial cotton fabric has the advantages of excellent and longlasting antibacterial performance, high ultraviolet stability, excellent use performance and important industrial application value.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a preparation method of an antibacterial cotton fabric loaded with bishydroxyhalamine compound / nano-titanium dioxide, which has high ultraviolet stability and good wearability. Background technique [0002] Bacteria, as pathogenic bacteria, are very harmful to human health, because human skin provides suitable temperature, nutrients and moisture, and these bacteria multiply very quickly on textiles. Cotton fabric is the textile material with the most contact with the human body. It has stronger hygroscopicity than synthetic materials and is more conducive to the reproduction of bacteria. With the continuous improvement of people's living standards and health awareness, the development of pure cotton textiles with antibacterial function has attracted more and more attention. Each glucosyl ring in the cotton fiber molecule contains 3 hydroxyl groups, which c...
