Abstract (en)
[origin: WO9405848A1] Method for imparting stain resistance to fibers, especially wool, which is adaptable to current wool processing methods. Steps comprise: A) treating fibers with a mordant; B) treatment with a combination of sulfonated or disulphonated surfactant together with a stain resist (e.g., syntan); and C) providing treatment with a fluorochemical in either step A, or B, in an amount sufficient to improve stain resistant properties. The improved method may be undertaken in the liquor remaining in a dye bath after dyeing fiber (spent bath process). Process pH is acid - 1.5 - 3.0 percent. Advantage: lowers the proportion of stain resist chemical to wool necessary to impart stain resistance. Tip sealing, using polymethacrylic resin and fluorochemical, may be an added step.
