Nylon fixative (fixation treatment for acid dyes)
Our "water-soluble phenolic resin" strongly bonds and adheres to nylon fibers and acidic dyes.
As an example of the applications of our water-soluble phenolic resin, we would like to introduce the "Nylon Fixing Agent." Our water-soluble phenolic resin is a resol resin made from dihydroxydiphenylsulfone (DHDPS) and phenolsulfonic acid. DHDPS has an electron-withdrawing sulfonyl group at its center, which gives it a much stronger hydrogen bonding capability at both ends compared to ordinary compounds like phenol, cresol, or tannic acid, allowing it to form strong hydrogen bonds with the azo groups of acidic dyes. By utilizing the ionic bonding strength between the terminal amino groups of nylon fibers and the sulfonic acid groups of the water-soluble phenolic resin, as well as the hydrogen bonding strength between the azo groups of acidic dyes and the hydroxyl groups of the water-soluble phenolic resin, the dye is fixed onto the fibers. *For more details, please refer to the PDF document or feel free to contact us.*
