AI Technical Summary

Problems solved by technology

Nano-TiO 2 It is a non-dissolution material. While degrading organic pollutants and sterilizing bacteria, it does not decompose or dissolve itself. It has a long-lasting photocatalytic effect and has a long-lasting effect of sterilizing and degrading pollutants. Unlike other antibacterial agents that will The dissolution of the agent leads to a gradual decline in the antibacterial effect

Embodiment 1

[0021] Take 10g Nano TiO 2 Photocatalyst powder, uniformly dispersed in 100g silica sol, at 120mL / m 2 amount and sprayed on white gauze, and dried at 80°C for 1 hour to obtain a gauze containing a photocatalyst layer, wherein the photocatalyst contained in the gauze is 4-15g / m 2 . Then move the pre-cultured Escherichia coli to the blank sample and the gauze containing the photocatalyst layer, count the number of colonies, and obtain the number of bacteria killed in 1 hour of contact time (see Table 1).

Embodiment 2

[0024] Take 10g Nano TiO 2 Photocatalyst powder, uniformly dispersed in 100g silica sol, at 120mL / m 2 amount and sprayed on the white gauze, dried at 30°C for 5 hours to obtain a gauze containing a photocatalyst layer, wherein the photocatalyst contained in the gauze is 4-15g / m 2 . Then move the Escherichia coli, Staphylococcus aureus and Candida albicans cultivated in advance to the blank sample and the gauze containing the photocatalyst layer, count the number of colonies, and obtain the number of bacteria killed in 1 h of contact time (see Table 2).

Embodiment 3

[0027] Take 10g Nano TiO 2 Photocatalyst powder, uniformly dispersed in 100g silica sol, at 120mL / m 2 and use the spraying method to coat it on the white polypropylene fiber cloth, and dry it at a temperature of 30°C for 5 hours to obtain a polypropylene fiber cloth containing a photocatalyst layer, wherein the polypropylene fiber cloth contains a photocatalyst of 4 to 15 g / m 2 . Then move Escherichia coli, Staphylococcus aureus and Candida albicans cultivated in advance to the blank sample and the polypropylene fiber cloth containing the photocatalyst layer, count the number of colonies, and obtain the number of bacteria killed in 1 hour of contact time (see Table 3).

Abstract

A fabric containing photocatalytic bactericide is prepared through preparing the solution of photocatalyst, coating it on fabric, and drying at 30-90 deg.C, for 1-5 hr. It can be used for on medical, bed, curtain, clothes and article of everyday use.

Description

technical field [0001] The invention belongs to the field of functional fabrics and antibacterial materials, in particular to fabrics containing photocatalytic bactericides and a preparation method thereof. Background technique [0002] Environmental pollution and sustainable development are the topics of concern to all countries. Environmental deterioration and the destruction of ecological balance have become serious threats to human society. The pollution of air and water, the proliferation of germs or other bacteria pose a threat to people's health. Due to semiconductor TiO 2 Under the irradiation of light, hole-electron pairs can be generated. The holes have strong oxidizing ability. Under a certain humidity and an oxygen atmosphere, they can generate superoxide anion radicals and hydroxyl radicals with strong chemical activity. These free radicals base can almost completely degrade most organic matter to H 2 O and CO 2 , and electrons have t...
