Effect of spinning conditions on characteristics of polyester-viscose MJS core yarns

Abstract

The effect of processing conditions in air-jet spinning on the characteristics of polyester-viscose core-spun yarns has been studied. It is observed that the increase in main draft leads to a significant increase almost in all mechanical characteristics. Reduced yarn linear density also has a potential for an appreciable increase in these characteristics. Increased spinning speed also provides a noticeable increase in yarn tenacity, breaking extension, initial modulus, energy-to-break, flexural rigidity, elastic recovery and abrasion resistance.
