J. Wilson, in Textile Design, 2011. Ring spinning. Ring spinning is a system of spinning that uses a ring spinning frame that drafts rovings (fibres prepared into loose strands ready for spinning where the fibres have been laid parallel to some extent), twists the yarn, and winds it on the bobbin continuously and simultaneously in one operation. Ring-spun yarns have a higher proportion of.

At present ring slub carded yarn is very popular to produce value added product for ornamentation purpose in the apparel industry. During spinning different parameters influenced the spinning performance. The main aim of this study was to investigate the effect of spindle speed as well as traveller weight on yarn quality. The Ne 28, Ne 30 and Ne 34 carded slub yarns were produced at the.
The ring spinning system is the oldest spinning system that remains dominant because of the high-quality yarns it produces. Ring spinning has various advantages besides disadvantages.It is the most flexible system from the viewpoints of fibers which can be used and the extent of the yarn counts which can be produced.
The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts.
In the ring spinning process of staple yarn, spinning triangle is a critical zone, whose geometry influences the mechanical properties of fiber in the spinning triangle directly. In the practical spinning, especially in some modified ring spinning systems, the spinning triangle is often asymmetric, in which the horizontal deviation of the twisting point is existed and lead to an obvious angle.
Ring spinning is a method of spinning fibres, such as cotton, flax or wool, to make a yarn.The ring frame developed from the throstle frame, which in its turn was a descendant of Arkwright's water frame. Ring spinning is a continuous process, unlike mule spinning which uses an intermittent action. In ring spinning, the roving is first attenuated by using drawing rollers, then spun and wound.
