Effect of Twist Factor and Filament Tension on Properties of Egyptian Core Spun Yarns

Summary

Filament tension and twist factor are important parameters that control filament central position and, consequently, properties of core spun yarns.
What is the expected interaction between them is a question that is answered in this article . Core spun yarns of Ne 60 were produced at two levels of core tension and five levels of twist factors. The core was continuous multi-filament polyester of 50 denier and the sheath was cotton Giza 70 . The experiments were carried out on a modified ring spinning frame that contains grooved tension rollers and additional dead weight tension devices. Yarn samples were obtained, tested and results were represented and discussed .
