A kind of preparation method and application of deodorant finishing liquid for cotton insoles

Abstract

The invention relates to a preparation method of cotton insole deodorization finishing liquid and application. The preparation method is characterized by comprising the following steps: firstly preparing a dispersion agent; grinding AgO, ZnO and TiO2 powder into nanometer grade particles; then, dissolving the nanometer grade particles into the prepared dispersion agent; preparing a nanometer oxideparticle water dispersion body; performing polymerization on acrylic acid, allyl glycidyl ether and dimethyl diallyl ammonium chloride with initiators to prepare polycarboxylates; mixing nanometer oxide particle water dispersion bodies and the polycarboxylates to obtain finishing liquid. The finishing liquid is used for finishing a cotton insole, and the prepared cotton insole is obtained. The prepared finished cotton insole has strong antibacterial performance against staphylococcus aureus, colibacillus and candida albicans; the bacteriostasis rate respectively reaches 99 percent, 97 percentand 97 percent or higher; after 20 times of washing, the strong antibacterial performance is still shown against staphylococcus aureus, colibacillus and candida albicans; the bacteriostasis rate reaches 94 percent or higher; the finished cotton insole has no odor in the whole test process. The preparation process of the cotton insole deodorization finishing liquid is simple; the application is convenient; the popularization is convenient.

Description

technical field [0001] The invention belongs to the technical field of textile finishing liquid, and in particular relates to a preparation method and application of a deodorant finishing liquid for cotton insoles. Background technique [0002] Insole is a kind of textile commonly used in people's daily life. Cotton insole has many advantages, such as: good comfort, good air permeability, etc. Therefore, cotton insole is widely used. Cotton insoles will produce odor after wearing for a long time. The reason for the odor of cotton insoles is that many bacteria are attached or parasitic on the cotton material, and the bacteria multiply in the insoles, resulting in odor. With the improvement of people's quality of life, people have higher and higher requirements for cotton insoles, that is, under the conditions of not affecting comfort and air permeability, the insoles worn do not emit odor. [0003] There are many antibacterial agents used in textiles, which can be roughly di...

AI Technical Summary

Problems solved by technology

[0003] There are many antibacterial agents used in textiles, which can be roughly divided into three categories: natural, inorganic and organic. Each type of antibacterial agent has its own advantages. For example, natural antibacterial agents usually have good safety, but their application range is narrow. Most seriously affect the shade of fabrics; organic antibacterial agents have many varieties and good effects, but they are not resistant to high temperature and have poor stability; inorganic antibacterial agents are difficult to obtain durable effects

Therefore, it is difficult to achieve a comprehensive effect by using natural or organic or inorganic antibacterial agents alone, and the mixed use of various antibacterial agents is an effective way to solve this problem

[0004] At present, there are many studies on the deodorant finishing of textiles. For example, Chinese patent application number 201210354187.6 discloses a special antibacterial and deodorant finishing agent for textiles. This patent is composed of a variety of broad-spectrum antibacterial agents. The binding force between the agent and textiles is weak, and its antibacterial and deodorant durability needs to be further confirmed; Chinese patent application number 201410460467.4 discloses an antibacterial and deodorant finishing agent for silk fabrics and its preparation method. The patent consists of titanium oxide, propylene glycol methyl ether acetate The antibacterial and deodorant finishing agent has a good antibacterial and deodorant effect on silk fabrics, but it is not necessarily suitable for cotton fabrics.
