Effect of Heat-Treated Process on Tensile Property of PLA Plied-Yarn

Abstract:

Polylactic acid (PLA) fiber, as a biodegradable synthetic aliphatic polyester fiber, has properties of biocompatibility, biodegradability and processing. Therefore, this study used PLA multifilament to prepare numerous plied yarns, respectively 75D, 75D×2, 75D×3, 75D×4 and 75D×5. Afterwards, these yarns were twisted with 3, 5, 7 twist/inch and then heat-treated respectively. The resulting yarns were tested for their tensile property tensile tenacity and tensile elongation. Moreover, the heat-treated effect was discussed on influencing tensile property.
