Developments on twist spinning (siro-spun) technology and hybrid spinning technologies

Recently, there has been an increasing focus on yarn spinning system as an economic alternative for conventional ring spinning as well as to produce yarns in better quality. In the literature, it is seen that most of the studies about these topics generally based on some developments on conventional spinning systems. To add to that, there are also some studies that aim to produce more economic and better quality yarn by combining conventional and modern systems. In this study, it was aimed to summarize the recent studies about siro-spun spinning that developed from conventional spinning, modifications on siro-spun spinning as well as the hybrid systems that also developed by combining different technologies and characteristics of yarns that produced on these systems.
