Open-end jet spinning is a new spinning method, which works in such a way that a high-speed air current forms the open end with the aid of roller drafting, while a high-speed rotating air current inserts twist to the sliver.
This paper proposes a new spinning method by using electromagnetic suspension theory to solve the problem in high-speed spinning process,and introduces the components and basic work principle of traveler electromagnetic suspension system,and also establishes a systematic mechanical model by linearization method.
Knitting yarn thin places are reduced and the yarn quality can reach Uster 5%~25% by adopting the measures such as cotton assorting reasonably,optimizing processing parameters & new type spinning accessories,strengthen operation & equipment maintenance and so on.
In this article, the covered-spun yarn which makes up of polyester and spandex is processed by the principle of parallel spinning, its another name is hollow spindle spinning, which is one of the new type spinning, the main use of parallel spinning is on the procession of fancy yarn.
Compact spinning is a new spinning technology based on traditional ring spinning.
