The Soiling Propensity of Open-End and Ring-Spun Yarns in Jersey Knit Fabrics

Abstract

Jersey knit fabrics of all cotton and 50/50 cotton-polyester representative of two yarn sizes of open-end and ring-spun yarns were evaluated with regard to their soiling propensity. An oily soil was applied to each fabric in the initial state, after 25 periods of laundering, and after 25 wcar-taundering periods, and subsequently the soiled specimens were exposed to five 45-minute laundering periods in a Launder-Ometer. Reflectance values taken before and after soiling and after laundering served as the basis for findings, which revealed that the condition of the fabric at the time of soiling was related to the amount of soil accepted and released by the fabrics. Additional findings generally pointed to the superior per formance of the ring-spun yarns, the cotton fibers, and the 37s yarns in repelling and releasing the oily soil.
