Problems solved by technology

[0004] There are many types of anti-mold products for leather goods, and some anti-mold products have good safety performance. However, due to the wide variety of molds on leather goods, most anti-mold agents with safe performance are often mainly aimed at the anti-fungal agents of mold products, which are often ignored. In order to avoid the harm caused by bacteria, the above antibacterial treatment methods do not select antibacterial agents for the unique bacteria or fungi on leather goods, so the antibacterial effect is limited, and most of them only have a single antifungal effect
Since leather goods need to be in direct contact with the skin, the reagents used are required to be harmless to the human body. However, commercial antifungal agents commonly used at present, such as benzoic acid and esterified didecyldimethylammonium, cannot guarantee the antifungal and antibacterial effect. At the same time, it will not cause harm to the human body

Abstract

The invention discloses a mildew preventive for a leather product and a preparation method thereof. A sterilizing mildew preventive composition for a straw mat consists of active components, a surfactant, an emulsifier, EDTA (Ethylene Diamine Tetraacetic Acid) and alcohol compounds. The active components are 3-indione-2-propinyl butyl carbamic acid ester and gallnut extraction liquor. An auxiliary material of the waterborne leather mildew preventive is added into a stirrer to stir and dissolved, and after uniform stirring and dissolving, the auxiliary material is canned to get the product of the mildew preventive. The invention discloses the mildew preventive for the leather product, so that the leather product is free from mildew for a long time, nonirritant to skin, safe and reliable to use and small in toxicity to environment, and has strong practical value.

Description

technical field [0001] The invention relates to an antifungal agent composition for leather goods, a preparation method and a use method. Background technique [0002] Leather products (leather shoes, leather clothes, leather bags, suitcases, etc.) are one of my country's bulk export commodities. Mildew of leather products is a very difficult problem that leather goods companies often encounter in production, transportation, storage and sales. Leather (including leather products) is a processed product of natural high molecular compound protein modified by tanning agent). It is easy to produce mildew under certain ambient temperature and humidity, and is corroded by mildew microorganisms, thereby reducing its appearance and inner quality. quality, and even spoil leather products. Mildewed leather products cause serious quality problems, making them lose their use value. Molds produce color deposits on leather products, which form stains. The growth of molds makes the dyein...
