Hercosett resin was applied to untreated wool samples using dispersions made with a cationic Hercosett resin and different optical brightener agents in order to improve both brightness and shrinkproofing properties. The brighteners used in this work were Blankophor BA liq B, Uvitex CF-200, Univtex NFW, and Uvitex WGS. The physi cochemical properties of the dispersion systems were also investigated.
