Comparison of Effectiveness Between Conventional Scouring & Bio-Scouring On Cotton Fabrics

A. M. K. Bahrum Prang Rocky Abstract-This study attempted to evaluate the eco-friendly bio-scouring and the conventional chemical (mainly NaOH) scouring processes of cotton & comparison between the effectiveness of both types of scouring process on cotton fibres and fabrics in the Textile industries. Less developed countries, like Bangladesh, do not set strict rules and regulations to discharge waste water from textile mills after wet processing fibres, yarns or fabrics which contains large amount of harsh and hazardous chemicals. As a result, environmental pollutions (like water, air pollution) are becoming the worst problem over the country. Common peoples are suffering from water-borne diseases, lack of drinkable water. Animals and plants lives are also destroyed gradually. Here, Effluent Treatment Plant (ETP) may be the good solution: which is used to purify waste-water from Hazardous chemicals. But, since textile processing needs lot of water (to produce one kg of textile fabrication approximately 200 liters of water is used) they had to pay lot of money which cuts their profit. In this intricacy, bio-scouring process may be a good substitute for chemical scouring which reduces ETP cost. But we can not ensure it as an only substitute since it does not give desired result in some cases.Still conventional scouring of cotton is the most widespread process for removing the fibres impurities to make the fibre absorbent for textile wet processing in commercial world. Though both have some restriction in the textile sector, they can be properly utilized by evaluating their respective advantages and disadvantages.This study provides a set of experimental results, discussion and comparison between the two processes.
