In this study, the effects of vacuum steaming process parameters on the physical properties of chenille yarns and fabrics were studied For this purpose chenille yarns were produced with viscose and acrylic pile and core yarns in different yarns counts. The chenille yarns were subjected to vacuum steaming at varying process parameters for example the steaming temperature (60, 80 and 110 degrees C) and steaming period (20, 40 and 60 minutes). According to the results of statistical analyses performed using experimental values obtained before and after vacuum steaming, physical parameters, like yarn count, twist, tenacity, elongation and work-of-break values were affected by the vacuum steaming process. An increase in fabric abrasion resistance was observed when the vacuum steamed chenille yarns were used as filling in the woven fabric construction. Process parameters are significant regarding change in yarn count and twist, but are insignificant regarding change in work-of-break values. Temperature is not a significant factor during any change in the tenacity of viscose chenille yarn, but is a significant factor in any change in the elongation values of acrylic chenille yarns.
