The current paper aims at determining the effect of rinse cycle softener treatment on water transmission behavior of fabrics made with 100% cotton and polyester.  The research work was conducted at Nishat Mills Limited (Dyeing and Finishing Unit). Two groups of samples were formulated. One group was given rinse cycle softener treatment and the other group was not treated with any softener treatment. Both groups were evaluated for their water vapour transmission by following test standard given by American Society for Testing and Materials ASTM E-96 at various washing intervals. The results depicted that rinse cycle treated fabrics had significantly decreased the water vapour transmission through their structure in cotton fabrics with increasing washing intervals. Whereas, no significant difference was observed for polyester fabrics. Moreover, fabrics treated with no softener treatment had increased the water transmission values for both groups. Findings of the study can be beneficial for the consumers to make a decision about the use of fabric softeners in hot climate by considering their change in structure or appearance of fabrics.
