A Study of the Structural and Physical Properties of Cotton-covered Nylon Filament Core-spun Yarns

TLDR: In this paper, structural and mechanical properties of core-spun yarns produced with a 2.2 tex monofilament core and a cotton wrap on a modified ring spinning frame are discussed and compared with the equivalent 100% cotton ring-spuns yarns.

Abstract: The spinning of core-spun yarn on the ring frame is a technique used to upgrade the cotton yarn properties. In a core-spun yarn, a filament is covered by a staple fibre. In the current paper the structural and mechanical properties of core-spun yarns produced with a 2.2 tex monofilament core and a cotton wrap on a modified ring spinning frame are discussed and compared with the equivalent 100% cotton ring-spun yarns. The tracer fibre technique which was used showed that there is no significant difference between the internal structure of the core- and ring-spun yarns. The investigation of twist and pretension of filament on the core-spun yarns showed that, in some cases, the optimum structural and mechanical properties of core-spun yarns could be achieved compared with the equivalent ring-spun yarn.
