In summer, especially in the Mediterranean Region, basic T-shirts produced of cotton fibers in daily wear are frequently used. Consumers wash these products by detergents to perform cleaning, maintenance and soften them by softeners to fulfill the expectations of softening, freshness and nice odor. In this study, the odor durabilities of softeners over t-shirts with the blends of 5 % elasthane and 95 % cotton, a popular blend for spring-summer wear, was searched. Softeners were chosen as one of them included microcapsules and the other one did not. After various keeping durations treated with home type of washing by an odorless detergent and the softener, 18 panelists wore them during a work day and evaluated the scents by a determined scale. As a result, during a busy work day, softener that contained microcapsules had more durable scents and was found superior by the panelists.
