Problems solved by technology

Existing conventional single-component antifungal compounds often have the effect of inhibiting or killing several kinds of molds, but have no obvious antifungal effect on other molds. not ideal
Moreover, the conventional method of sterilization and anti-mildew uses a large amount of anti-fungal agent and a large loss, resulting in a large amount of waste water and heavy pollution.

Description

technical field [0001] The invention relates to a bactericidal and antifungal agent for leather, in particular to a bactericidal and antifungal agent composition for discolored leather, a preparation method and a use method. Background technique [0002] Leather mildew is a common quality problem during the use of leather. This is because leather is usually made of two or three layers of leather. The leather is composed of protein fibers. The fungal spores that fall on it first germinate and grow using their own stored nutrients At the same time, protease is secreted, and the leather becomes their nutrition, which is beneficial to their growth and reproduction. At present, the most important method used to prevent mildew in leather and products at home and abroad is to add bactericidal and antifungal agents in the treatment process of raw hides and cow split semi-finished leather. At present, most of the antifungal agents used in China are single-component compounds, such a...
