ʷ Polymer cationic agent was prepared by the initial polymerization of epichlorohydrin followed by amination with diethyl-amine. Cotton fibre treated with the polymer (68% o.w.f.) is highly cationic and exhibit increased substantivity for anionic dyes. The modified substrate could be dyed with direct dyes without salt or a little salt from dye bath. The increased concentration of cationic agents resulted in an increase the colour yield. Futhermore, treated cotton has an electropositive surface charge. Adsorption of direct dye can be attributed to both van der waals force and electrostatic attraction.
