Problems solved by technology

In comparison, the antibacterial effect of the fabric obtained by the first method is relatively long-lasting, that is, the washability is good, but the production process of the antibacterial fiber is relatively complicated, and at the same time, the amount of antibacterial agent is relatively large, and the relative utilization rate is relatively low.
The processing process of the second method is relatively simple, and so far, post-processing is the only feasible technology for textiles made of pure natural fibers, but the antibacterial effect and washability of the resulting fabrics are relatively poor
[0004] In the invention patent with the application number CN200910196831.X, a method of manufacturing nano-zinc oxide and titanium dioxide composite antibacterial polyester fiber is introduced. It has the characteristics of broad spectrum, durability, safety and non-toxicity. However, its processing process is mainly Zinc oxide, titanium dioxide and polyester masterbatch are simply mixed, which is difficult to ensure the compatibility of metal oxides and polyester, which may lead to poor washing resistance, and the physical and mechanical properties of the raw materials themselves may be affected during the mixing process performance
In the invention patent with the application number CN201210197573.9, a method for preparing antibacterial and anti-ultraviolet fibers and fabrics loaded with nano-titanium dioxide is introduced. Hydrolysis and polymerization to generate nano-titanium dioxide, however, it does not have a broad spectrum, and cannot guarantee that all titanium dioxide will enter the pores and be lost, resulting in poor washing resistance

Abstract

The invention provides a titanium dioxide textile and a preparation method thereof.The titanium dioxide textile is prepared from, by weight, 100-200 parts of pure cotton cloth, 20-60 parts of a titanium dioxide antibacterial agent, 0-1 part of a dispersing agent, 5-10 parts of a binder, 1-2 parts of a thickener, 200-300 parts of alkali liquor and 20-50 parts of water, wherein the titanium dioxide antibacterial agent is mainly prepared from tetrabutyl titanate, 1-acetoxy-3-propane sulfoacid imidazole bromine salt and a metal organic framework material.Accordingly, the prepared titanium dioxide antibacterial textile is good in antibacterial effect, strong in fabric affinity and good in washing fastness, is environmentally friendly and keeps the hand feeling of fabric fibers.

Description

technical field [0001] The invention relates to the antibacterial field, in particular to a titanium dioxide textile suitable for antibacterial and a preparation method thereof. Background technique [0002] With the development of economy and society, people's self-care awareness and environmental awareness are also increasing, and the demand for special functional textiles for various purposes is also increasing sharply. Health is still one of the most concerned topics, but bacteria are everywhere, including many harmful bacteria that cause diseases to the human body, and their spread and spread seriously threaten human health. Therefore, in order to control and eliminate the growth and reproduction of harmful bacteria, and reduce or eliminate the possible harm caused by bacteria, the research and development of antibacterial functional textiles has become a hot spot in the field of scientific research and production. [0003] The current antibacterial fabric processing m...
