Abstract
In this research, the B/A/S composite yarns were fabricated using the stainless steel wires as core yarn, antibacterial nylon and bamboo charcoal polyester filaments as inner wrapped yarn and outer wrapped yarn, respectively. The composite yarns with a wrapping number of 8, 11, 14 turns/cm were fabricated on a hollow spindle spinning machine. Furthermore, the composite fabrics were woven with the B/A/S composite yarns as weft yarns and the PET as the warp yarns. These fabrics were evaluated in terms of far infrared (FIR) emissivity and the air permeability. The presence of the bamboo charcoal was found to increase the FIR emissivity. The highest of the FIR emissivity was obtained when the weft yarns with a wrapping number of 11 turns/cm. The lamination numbers of the woven fabrics varied from 1-5 layers. The far infrared emissivity and air permeability of the woven fabrics was 0.94 and 268 cm3/cm2/s when the lamination numbers was 2 layers and the wrapping number was 11 turns/cm.
