Abstract

The invention discloses a production process for odor-resistant antibacterial leather. The production process comprises the following steps: de-fatting, neutralizing, dyeing, heating and stuffing, solidifying acid, carrying out odor-resistant antibacterial treatment, bloating and standing, and drying and milling, thereby obtaining the odor-resistant antibacterial leather. According to the production process, anionic dye and an anionic type stuffing agent to solidify acid, and a cationic type antibacterial agent and a cationic type color fixing agent can be used for increasing the bonding strength of the material after water washing, so that material transfer is avoided.

Description

technical field [0001] The invention belongs to the field of leather production technology, and in particular relates to a production technology of deodorant and antibacterial leather. Background technique [0002] The reason for foot odor is that there are many sweat glands in the soles of the feet (there are about 620 sweat glands per square centimeter, while other parts of the body have only 143-339 sweat glands in the same area). When people's activities increase and the weather is hot, they tend to sweat. Apart from water and salt, sweat also contains lactic acid and urea. In hyperhidrosis, the bacteria on the feet proliferate and decompose keratin, plus the lactic acid and urea in the sweat, which will produce a bad smell. If the shoes are not breathable and the air in the shoes does not circulate, the odor will accumulate and become stronger, and the odor will be extremely strong. [0003] People with foot odor generally experience symptoms such as sweating and itch...
