Sustainability in textiles is now a day’s key demand of consumers and traders, where the process with zero effluent emission or less emission has been considered for aim to utilize the ecofriendly process in direct dyeing of cotton to minimize effluent load. For this purpose, variable amount of Table salt and Glauber salt has been used to achieve maximum exhaustion during direct cotton dyeing. Different dyeing variables have been employed, shade made at the optimum conditions were assessed according to ISO standards. It has been found that 3g/100mL of table salt for Direct dyeing of cotton using 40mL of DR 28 (8pH) at 65oC for 45 min, whereas using 40mL of DB 15 (8pH) for dyeing of cotton at 65 °C for 45min containing 3g/100mL of Glauber slat has given acceptable color characteristics. The reduction in dyeing variable using low salt amount has proved that this method is cost, time and energy efficient process, which can be utilized for dyeing of natural fabrics using various classes of dyes to obtain sustainable textile products.
