Fastness properties are adequate and quite comparable with conventionally dyed samples. The wrinkle resistance of the dyed fabric also improves. The dyeing of cotton with reactive dyes using polyacrylamide in the dye bath improves the dye ability of cellulosic fabrics with reactive dyes and reducing effluent discharge.

When dyeing the modified substrates, reactive dyes can be much more efficiently exhausted and fixed onto cellulosic fabrics under neutral conditions in the absence of salt. The modifications show an overall suitability for different reactive dyes. The modified dyeing do not suffer either from a significant drop in light fastness, wash fastness or from duller shades.
