After treating the fibers with our "water-soluble phenolic resin" and carrying an antibacterial agent, it imparts excellent wash durability and antibacterial properties to the fiber products!
Our water-soluble phenolic resin demonstrates high adhesion even to substrates without bonding agents, such as polyester and cellulose. In addition to the hydrogen bonding strength between the hydroxyl groups of DHDPS and the carbonyl or hydroxyl groups of the substrate, the crosslinking (thermosetting) using the methylol groups at the ends of the resol-type water-soluble phenolic resin results in high durability. After surface treatment with the water-soluble phenolic resin, if substances with antibacterial properties (such as amine hydrochlorides) are supported, the strong interaction between the antibacterial agent and the water-soluble phenolic resin can impart excellent wash durability and antibacterial properties to textile products. *Please feel free to download detailed materials or contact us for inquiries.*
