In this paper, we present a fiber modification technique based on Polymer PL. The treatment shows commercial potential for improving the dyeability of cotton and re ducing the effluent discharge from dyeing processes. By examining the dyeing behavior of a wide range of reactive dyes, we have found that the modified substrates can be dyed more efficiently, even under neutral to slightly acidic conditions and in the ab sence of salt, with satisfactory dyeing quality.
