A cost minimization process of heat and energy consumption for direct dyeing of cotton fabric coloration with triethanolamine

Abstract

A cost minimization concept of heat and and energy consumption for direct dyeing process of cotton fabric coloration was experimented with triethanolamine instead of sodium carbonate in the dyebath of direct dyeing with low temperature at C medium temperature at Cand high temperature at Cand compared with the conventional method of direct dyeing with high temperature at Cwhere an acceptable range of increasing color strength K S and color difference were observed for low temperature dyeing with triethanolamine TEA method comparing to the conventional dyeing process of high temperature with sodium carbonate SC method Considering heat and energy consumption in direct dyeing of cotton fabric coloration with triethanolamine method the low temperature dyeing cost was minimized Rs comparing to high temperature sodium carbonate method dyeing cost
