Scouring of 100% Cotton Knitted Fabric with Soap-nut: A Sustainable & Economic Approach Towards Textile Pre-Treatment

Abstract

Commercial detergent contains a higher amount of amphiphilic molecules, which helps to neutralize the surface tension of water and are mostly used in the pretreatment of fabric at industrial level. But the industrial waste water containing detergent in it, can be disastrous to the aquatic domain out there. This study is focused on the comparative study of natural detergent (Soap-nut/reetha) & synthetic detergent in case of 100% cotton knitted (S.J) fabric. Mainly I focus on the pre-treatment, shade differences, wash and rubbing fastness of following cotton fabric pre-treated & dyed with both conventional and with the use of soap-nut. After completing, the quality parameters such as shade differences, spectrophotometric evaluation, rubbing, and wash fastness of both type of dyed samples have been compared. From the comparison, found that the sample pretreated with soap-nut & then dyed are lighter in shade but the other quality parameters are somewhat satisfactory.
