In today’s technology, many spinning systems are used commercially to produce spun yarns with a wide range of values of characteristics. Among these systems, ring spinning enjoys the greatest diversity and the highest quality levels. Ring spinning has been able to supplant almost all other conventional spinning methods and has proved very resistant to inroads by the newcomers. This can be attributed mainly to its flexibility, universal applicability, and yarn quality.
Other new spinning systems such as rotor spinning, air-jet spinning, and friction spinning suffer inherent limitations that make them suitable for only narrow ranges of yarn count and twist levels. However, the major limiting factor in ring spinning is their low production rate in comparison with all new spinning technologies. Typically, ring-spinning can only operate at a production speed of up to 30 m/min, while other systems producing comparable yarns (such as rotor spinning and air-jet spinning) can operate at production speeds of up to 250 m/min. The low production rate in ring spinning is primarily attributed to the use of the ring/traveller system for twisting and winding.
