A Review of Ring Staple Yarn Spinning Method Development and Its Trend Prediction

In this article, ring staple single yarn spinning method development has been reviewed after an introductory background about ring spinning principle and ring staple yarn defect problems. The review concludes that previous novel ring staple spinning methods have been developed mainly on a basis of staple spinning strand control enhancements by means of separating single strands into two or several subones, concentrating triangular ring spinning strand, rewrapping protruding fiber ends, and improving online twisting density distribution. Reputed novel ring spinning technologies are included in this review such as siro-spinning, solo-spinning, compact spinning, air-jet spinning, air-suction spinning, and Nu-torque yarn spinning. The inadequacy of some reviewed novel spinning methods is considered as a motility of ring spinning method further development. It is predicted that ring staple spinning can be further developed via increasing spinning efficiency and improving online spinning strand properties.
