Preservatives and fungicides commonly used in textile yarns and fabrics are a type of chemical auxiliaries that can inhibit or kill microorganisms (such as bacteria, fungi, and yeasts). Their core function is to prevent problems such as mold, rot, odor, and strength reduction caused by microbial growth during the storage, processing, or use of textiles. The following is the specific introduction:

Wood decay is mostly the result of mold infestation. Hydrolytic enzymes in wood rot bacteria can decompose cellulose, lignin and cell contents, which make up wood cell walls, as raw materials for growth. Continuous absorption reduces the toughness of wood gradually until it loses all carrying capacity.

How should antifungal agents be used? The correct use method of the antifungal agent, the addition method or the method called in, is to directly add a certain proportion of the antifungal agent to the material or product. It can be added at the same time as the raw materials, it can also be added at a certain point in the middle, or even in the finished product. Powders can be added, or agents that have been dissolved in advance with water or other organic solvents can be added.
