Influence of Tencel/cotton blends on knitted fabric performance

The requirements in terms of wearing comfort with sportswear, underwear and outerwear are widely linked to the use of new fibers. Today, Tencel fiber is one of the most important developments in regenerated cellulosic fiber. However, the relation between Tencel fiber properties and fabric characteristics has not been enough studied in the literature especially the influence of fiber materials on mechanical, Ultraviolet Protection Factor (UPF) and absorption properties. Therefore, in this study, knitted fabric samples were manufactured with eight different yarns with two fabric types (single jersey and single jersey with Lycra). 30/1-Ne yarns from natural and regenerated cellulosic fibers: 50% Tencel-LF/50% cotton, 67% Tencel-LF/33% cotton, 67% Tencel-STD/33% cotton, 70% bamboo/30% cotton, 100% bamboo, 100% Modal, 100% Micro-Modal and 100% cotton were employed. Then, all the produced fabrics were subjected to five cycles laundering and then flat dried. The results show that 67% Tencel-LF/33% cotton has more flexural rigidity and withdrawing handle force than 67% Tencel-STD/33% cotton fabric, while 67% Tencel-STD/33% cotton has a merit of durability during bursting test. Blending Egyptian cotton fibers with bamboo and Tencel as in 70/30% bamboo/cotton and 50/50% Tencel-LF/cotton improve UPF of the produced fabric
