Minimizing pollution during dyeing of bio-polished cotton fabric using eco-friendly microwave technique

Abstract

Minimizing pollution in textile industry is gaining much attention nowadays. Microwave irradiation technique is one of the best techniques used recently to reduce environmental pollution via saving time, energy, as well as cost. The present work concerned with comparison between two dyeing techniques; conventional and microwave irradiation; of bio-polished cotton fabric with reactive dyeing process. The effect of dye concentration, temperature, liquor ratio, as well as auxiliaries added on the dyability of bio-polished cotton fabrics, was studied. The optimal irradiation parameters were chosen with respect to the colour strength and wash fastness. Physico-mechanical and fastness properties as well as durability of the two techniques were evaluated. Microwave techniques showed the best results as the fabric thickness, crease recovery angle, the warp set the weft sett and wettability increased after enzymatical treatment and microwave dyeing.
