Abstract
Dyeing formulations for Nylon/Cotton blends very difficult and can involve a different dye class for each component in one or two baths. The dyeing process is complicated by the difference in reactivates of these two fibers. When dyeing Nylon and Cotton in the same bath there is preferential dye uptake by nylon, in the final, color correction may be required for union shades. These difficulties in wet processing of Nylon /cotton blends including dyeing to union shades impeded their constant market share many investigations are achieved to concede the cotton chemically modifying with amino or quaternary ammonIUm groups functionality which make the cotton dye similarly to nylon in a nylon dye bath. This system suggests easy processing with one dye in one bath provided Nylon and cotton an equally competitive for the anionic nylon dyes under acidic condition.
The implementation of UnIon dyeing should help promote Nylon /cotton. and lead ultimately to more favorable marked position.
In this work union dyeing for Nylon /cotton blend fabric was achieved using one dye (acid dye or direct dye) and one bath through a chemical modification of the cotton via a one of the cationizing agent.
