摘要

Yarn structure influences the configuration of the constituent fibers in the yarn and the comfort properties of the fabrics to a great extent. The fiber arrangement in the yarn has a major influence on the comfort-related properties such as thermal conductivity, air permeability, wickability, and moisture vapor permeability. This study dealt with the influence of process and material variables namely, polyvinyl alcohol (PVA) proportion, twist multiplier (TM), and spindle speed on microporous viscose yarn properties. Three-variable three-factor Box and Behnken method was used to investigate the individual and interaction effects of selected variables on yarn properties. The selected variables have a significant influence on all the yarn properties. The increase in PVA%, spindle speed, and TM reduces the specific volume and wickability of yarns and increases the tenacity and packing factor of yarns before dissolving the PVA fibers. With increase in spindle speed and TM, same trend was noticed after dissolving the PVA also. But the trend reverses with increase in PVA percentage after dissolution of PVA fiber. The increase in PVA percentage increases the specific volume and wickability of yarns and decreases the tenacity and packing factor of yarns after dissolution of PVA fiber. The optimized process parameters were obtained, and yarn was spun with the optimized parameters to validate the model.
