Colour woven goods

This combination is comparably milder combination than that of caustic soda and hence ideally suitable for more delicate cloths and colour woven goods compensating for the slower action of the milder alkali by the addition of a detergent. Anionic products like sodium alkyl sulphates and alkyl aromatic sulphonates and non-ionics like polyethoxylated compounds are used as detergent. Sometimes mixtures of anionic and non-ionic products are used. It is possible to obtain a synergistic effect between a detergent and alkali, so that the two agents when combined increase their total activities rather than inhibit each other. Fig. 4-2 shows the syn-...
