To eliminate the usage of salt, salt-free reactive dyeing using CHPTAC (3-Chloro-2-hydroxypropyl trimethylammonium chloride) has been proposed. Studies have shown promising results, such as better dye shade attainment and less effluent load compared to conventional methods. In this work, to improve the effective utilisation of CHPTAC, the cotton fabric has been treated with cellulase enzyme and the application of CHPTAC is carried out using the ultrasonication technique. The samples are then characterised for colour parameters and it is found that the enzymatic treatment and ultrasonication lead to improve the dye uptake, as the interaction of CHPTAC with the fabric becomes better.

Abstract


To eliminate the usage of salt, salt-free reactive dyeing using CHPTAC (3-Chloro-2-hydroxypropyl trimethylammonium chloride) has been proposed. Studies have shown promising results, such as better dye shade attainment and less effluent load compared to conventional methods. In this work, to improve the effective utilisation of CHPTAC, the cotton fabric has been treated with cellulase enzyme and the application of CHPTAC is carried out using the ultrasonication technique. The samples are then characterised for colour parameters and it is found that the enzymatic treatment and ultrasonication lead to improve the dye uptake, as the interaction of CHPTAC with the fabric becomes better.
