I. Overview of the Requirements for Antibacterial Modification of Spunbond Nonwoven Fabrics PP spunbond non-woven fabric is widely used in fields such as medical protection, hygiene care, and household filtration. The common base material is prone to the growth of Escherichia coli, Staphylococcus aureus, and mold, presenting problems such as cross-infection, unpleasant odors, and moldy conditions.

Household plastic parts cover all scenarios of food preparation, storage and storage. Different usage environments give rise to different hygiene risks. A single antibacterial solution is unable to meet all requirements:

The rubber and plastic products have been upgraded with antibacterial functions. The stability, safety and processing compatibility of the core raw materials directly determine the quality of the finished products. Many rubber and plastic processing factories and product enterprises, when producing antibacterial plastics, will look for reliable and well-coordinated plastic antibacterial masterbatch brands. Dalian Tianwei , which has been deeply engaged in the field of microbial control additives for many years

Fully polyester fabric is widely used in printed home textiles, sportswear, outdoor luggage, industrial filter cloth, etc. Polyester itself does not mold, but the residues of sizing, dyes, and oils left from printing and dyeing will cause mold growth in the fabric during high-temperature and high-humidity storage, ocean transportation, and rainy seasons, resulting in mold spots on the fabric surface, color bleeding on the printing, fabric odor, and decreased color fastness, leading to batch returns and losses.

Water-based anti-corrosion coatings use water as the solvent, and have a high organic content of emulsions and additives. After storage in the tank and formation of the coating film, they are prone to bacterial, yeast, mold, and sulfate-reducing bacteria growth. They are a high-risk category in the coatings industry, presenting four prominent production and usage pain points:

The paper-faced gypsum board mold inhibitor is a specialized functional additive tailored for the characteristics of gypsum board substrates. It is mainly used to address the mold growth problems caused by moisture, closed environment, and suitable temperature and humidity during the production, storage, installation, and use of paper-faced gypsum boards. It can effectively prevent the occurrence of blackening, mold growth, powdering, delamination, and odors on the boards, ensuring the structural stability and indoor decoration effect of gypsum boards, and is widely applicable to gypsum board decoration projects in humid residential and commercial spaces.

The spinning oil agent preservative is a functional additive specifically designed for the textile and chemical fiber industry. It is mainly developed for spinning oil agent systems of polyester, nylon, polypropylene, etc.

The paper pulp contains cellulose, hemicellulose and water. In the production environment with a pH of 4-8 and a temperature of 25-45℃, it is highly prone to the growth of bacteria, molds, yeasts and algae and other microorganisms. The metabolic activities of these microorganisms will decompose the fibers and produce mucus, leading to problems such as rotten pulp, paper holes/black spots/ruptures, equipment sludge blockage,
