Comparative analysis between conventional pre-treatment and bio - pre-treatment of cotton fabric

摘要

The textile is a growing sector which traditionally requires huge amount of water, energy, harsh chemicals, starting from pesticides for growing cotton to a variety of finishing chemicals. This results in high amounts of wash water in waste streams causing environmental burden. This paper attempts to evaluate the eco-friendly bio scouring and conventional chemical scouring process of cotton. The comparison between the effectiveness on both types of scouring process on cotton fabric and textile industry has been presented. Water, cellulosic enzyme and chemicals are selected. Cotton fabric is treated with selected bio-processing agents. The finished fabric is evaluated for column test, absorbency test and drop test. Since use of the gentle enzyme process replaces the need for harsh processing with sodium hydroxide and other harmful chemicals, there is less contribution to the textile effluent and gives a softer textile.
