Cost Comparison of Ring Spun Yarn of China Hui Hong Polyester Fiber and Blended Yarn of Khalis and PSL Polyesters Fiber

Redistribution of Fibers in the Structure of Hollow Ring Spun Yarn

Core yarn was spun by introducing a PVA multifilament as the core through the yarn forming zone of a ring spinning frame and viscose fibers as the sheath containing tracer fibers. The water soluble PVA multifilament was extracted from the yarn structure. Then internal structure and properties of the hollow ring yarn was assessed and compared with those of typical ring yarns. Also, two plain fab...

Production of Core Spun Yarn with Ring & Siro Spinning System

A common problem in production of core–spun yarns on the Ring spinning frame is the slippage of the staple fibers as sheath fibers relative to the core. This effect is known as ‘strip-back’ or barberpole. This problem may lead to an incomplete core coverage and results in end–breaks in subsequent processing. In order to avoid this problem, in the present work, core spun yarns (acrylic sheath fi...
