Abstract
Exhaust dyeing method was used for the eco-friendly dyeing of cotton fabrics by using biodegradable salts such as potassium acetate(CH3CO2K) along with sodium bicarbonate. The experimental work carried out in the ratio of any biodegradable salts two grams and for obtaining pH (<10) of the solution sodium bicarbonate (NaHCO3) was used,salts and four different reactive dyes were mixed separately in distilled water. Sodium bicarbonate was used to make the pH alkaline and for the completion of reaction. The cotton that was used (Twill weave cotton with the ends per Inchof 140 and pick per Inch 60).At last TDS value of the left effluents were taken through seven conductivity meter, by using biodegradable salts (potassium acetate) 25-30 % effluent were reduced. The color fastness to laundering, color fastness to crocking and color fastness to light of all fabric specimensdyed with all reactive dyes was found at good level. In replacement of sodium chloride, potassium acetate have been successfully employed to make the process environment friendly.
