Abstract

Denim is one of the most popular choice for garments industry in today’s world, so the production process of denim requires swift method for faster production cycle. Moreover, the vogue of denim depends on its outlook which is accomplished by different washing techniques. In this study one of such quotidian washing method is used but main motive is to find out the minimum time and temperature in which stone washed denim fabric provide satisfactory results. Here denim samples are washed with pumice stone rather than using any kind of enzyme. Washing is done in two ways such as at fixed temperature (28 0C) with various time duration (30,35,40,45minutes) and at fixed time cycle (25minutes) in different temperature (40,45, 50 and 55 0C). After washing, different color fastness values such as color fastness to wash, water, perspiration and rubbing are determined along with tear strength value and pH value to measure the strength and comfortability of the washed denim.
