Sea water for reactive dyeing of cotton fabrics

Abstract

In this research work, trials have been taken up with sea water, as an alternative, for dyeing of cotton with different shades of reactive dye and different salt level contents. Dyeing has been carried out with hot brand reactive dye Red H8B using normal water, RO water and sea water (with and without salt). It is inferred that the exhaustion and fixation of the dye are better in case of sea water dyeing. The wash, rub and perspiration fastness are good for sea water dyeing and in some cases the ratings are comparable and in most case the ratings are similar to that of the ground water and RO water dyeing.
