SPINNING A Yarn is usually of substantial length & of a small cross-section. In the cross-section of yarn, there are usually multiple numbers of Staple fibers (short fibers) or Filaments (long fibers) of unlimited length. Spinning is the process of creating yarn (or thread, rope, cable) from various raw fiber materials. Several fibers are twisted […]
Classification of winding machines broadly based on package, winding, drive, and type of yarn used.Also, the various faults of the winding are specified. Some common causes of the faulty winding are also discussed.
How to determine winding calculation and what is the objective of winding?The entire parameters along with the winding requirements and objectives.
The cop which is prepared in the ring frame is not suitable for further processing. So the yarn is converted into the shape of a cone which is prepared in the winding. Practical experience shows that winding process alters the yarn structure. The factors which affect the yarn structure during winding are bobbin geometry, bobbin unwinding behavior, and binding speed. This phenomenon does not affect the evenness of the yarn but it affects the properties of the yarn such as thick and thin places.
