Spinning is the process of drawing out and twisting a mass of cleaned, prepared fibres. Filament yarns generally require less twist than do staple yarns.
通过分析，认为PTT弹性长丝包芯纱线及短纤维混纺纱线的筒子染色关键，是使其充分收缩，以达到适宜弹性；
This paper introduces the key step of fully shrinking for suitable elasticity in cheese dyeing of PTT filament core-spun elastic yarn and staple blended yarn.
梳棉工序继续进行除杂工作，除去不宜纺纱的短纤维。
Carding continues the cleaning of the fibers. It removes fibers too short for use in yarns.
醋酯短纤维可以通过切断连续长丝而获得。短纤维的长度应能适于与其它纤维混纺制成混纺纱线。
Acetate staple is now produced by cutting the continuous filaments into short lengths. The staple length is chosen to blend suitably with other fibers in making mixed yarns.
