dc.description.abstractThis study primarily focused on the reduction of salt based pollutants during the dyeing of fabrics by using a biodegradable salt. Optimal process conditions have been achieved regarding quantity of biodegradable salt and color fastness of the dyed fabrics. The dyeing method used was pad steam dyeing and dye strength used was 20 g/L. Fabric samples were dyed by padding. After padding steaming was done in a steamer for around 60 seconds. After dyeing, washing off was carried out to remove any un-reacted dye. To remove any unfixed dye which might have been left after washing, the fabric was further boiled with dim ethyl form amide solution to strip off any unfixed dye on it. Good results have been obtained by using pad steam dyeing of fabric using bio-degradable salt such as Tri-sodium nitrilotriacetate which reduced the amount of salt in effluents to about 30%. The method for dyeing has been improved and tested on a pilot plant in a textile industry to check large scale useful uses of the salt and method at the same time. The study showed that the selected bio-degradable salt can be used for pad-steam dyeing of cotton with reactive dyes to take the place of conventional salt. Tri-sodium nitrilotriacetate gave better dye fixation and color fastness as compared to the conventional salts.en_US
