Problems solved by technology

For example, most of the existing antibacterial shoe materials have good antibacterial effects on typical bacteria such as Escherichia coli and Staphylococcus aureus, but have no obvious effect on fungi that actually cause foot diseases
Silver-based antibacterial agents can easily cause discoloration of the base material under light conditions, affecting the appearance of the shoe material

Abstract

The invention provides a preparation method of antibacterial sol for shoemaking and an antibacterial finishing method. The preparation method and the antibacterial finishing method include: using TEOSas the precursor, EtOH as the solvent and HNO3 as the catalyst, adding a certain amount of GPTMS and TH, electrically stirring for 5 hours at hydrolysis temperature of 30 DEG C, and standing at roomtemperature for a certain period of time to obtain the transparent antibacterial sol; using a padding finishing process to perform antibacterial finishing on lining fabric for shoes, soaking the fabric into the transparent antibacterial sol for a certain period of time, using a rolling manner to press the transparent antibacterial sol into the gaps of the fabric, and removing the redundant transparent antibacterial sol at the same time. Compared with the prior art, the antibacterial finishing method has the advantages that the two-dipping two-rolling process with the pick up being 70-80% is used under the conditions that dipping time is 10 seconds, pre-drying temperature is 130 DEG C, pre-drying time is 2.5 minutes, drying temperature is 190 DEG C and drying time is 40 seconds, the processed shoe material is good in antibacterial effect on Candida albicans and Trichophyton rubrum, and the antibacterial rate is larger than 90%.

Description

technical field [0001] The invention relates to the field of shoe-making antibacterial technology, in particular to a method for preparing an antibacterial sol for shoemaking and an antibacterial finishing method. Background technique [0002] Shoes are the necessities of people's daily life. With the development of society and the improvement of people's living standards, people have higher and higher requirements for the comfort and hygiene of shoes and boots. In recent years, the antibacterial agent and antibacterial fabric industry has gradually matured. Some international and domestic scholars have tried to apply it to footwear products, and a number of antibacterial agents and antibacterial shoe materials for shoes have emerged on the market. [0003] Although footwear antibacterial materials have emerged in the market, there are still many deficiencies in the application of antibacterial agents in footwear. For example, most of the existing antibacterial shoe materi...
