Synthetic yarn draw-twisting - uses a two-for-one twister together with drawing and thermal treatment stages

摘要

Yarn is draw-twisted using a two-for-one twisting machine to give high twisting and winding, at the same time as or immediately after the drawing and thermal treatment stages. Designed for use with high polymer mono- or multi-filament yarns, the process allows a continuous feed of yarn to a two-for-one twisting machine.
