Abstract

Polymer cationic agent was prepared by the initial polymerisation of epichlorohydrin followed by amination with diethylamine. Cotton fibre treated with the polymer (6~8% o.w.f.) is highly cationic and exhibit increased substantivity for reactive dyes under neutral to weakly acid conditions. The modified substrate could be dyed with reactive 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 Reactive dye can be attributed to both van der waals force and electrostatic attraction.
