Abstract
It has been a universal method to obtain better-property yarns by blending different kinds of fibers together. This study, was aimed to investigate the mechanical and physical properties of far-infrared tencel/acrylic (FIT/A) and far-infrared tencel/cotton (FIT/C) blended ring-spun yarns. Yarn samples with five different blend ratios (100/0, 65/35, 50/50, 35/65, 0/100) were spun as 19.7 tex on a ring spinning system. The elongation, breaking strength, yarn irregularity, and hairiness of the two sets of blended yarns were analyzed using the simple rule of mixtures (ROM) and generalized rule of mixtures (GROM). The results show that acrylic blended yarns show higher elongation values, similar breaking strength, lower yarn irregularity values, and higher hairiness values compared to cotton blended ones. In addition, the interactions between the two fibers in both the two sets of yarns have a positive effect on yarn elongation, breaking strength, and yarn irregularity; but a negative effect on the hairiness with a different degree.
