Although reactive, direct, sulphur, vat or naphthol dyestuffs can all be used for cotton dyeing, recently cotton has been being dyed with reactive dyes for the most parts due to their bright shades and high wet fastness property. However as the labor, dyestuff, and chemical cost are increasing, direct dyes can be a good choice for cotton dyers.
Direct dyes can be used economically and simply for the dyeing of cellulosic fibre with practical level of colour fastness. The application of direct dyes to cotton dyeing will bring economical benefits as it can reduce dyeing-cost in terms of time and money.
