Abstract
To satisfy the many requirements of our daily life, complex textiles that are both functional and beneficial have been successfully designed and developed. This research investigates the design of bamboo charcoal/spandex (BC/S) complex yarns, fabricated with a blend of spandex and bamboo charcoal polyester textured yarn, which possess superior elastic recovery. The expansion multiples of the spandex was 1.5–3.5, the wrap counts are 2 −4.5 turns/cm, and the speed of the rotor twister was 4000-12000 rpm. When the speed of the rotor twister was between 4000 and 12000 rpm, the expansion multiple was 1.5 and the elastic recovery rate was maintained at 93% or above. Furthermore, the far infrared emissivity of BC/S complex knitted fabric was over 0.9, but descended with the lamination number. The BC/S complex knitted fabric also contained an anion count of 356 anions/cc.
