Overview of Winding

Ring spinning produces yarn in a package form called cops. Since cops from ringframes are not suitable for further processing, the winding process serves to achieve additional objectives made necessary by the requirements of the subsequent processing stages.

Following are the Tasks of Winding Process

• Extraction of all disturbing yarn faults such as the short, long thick ,long thin, spinners doubles, etc

• Manufacture of cones having good drawing - off properties and with as long a length of yarn as possible

• Paraffin waxing of the yarn during the winding process

• Introduction into the yarn of a minimum number of knots

• Achievement of a high machine efficiency i.e high produciton level 

The winding process therefore has the basic function of obtaining a larger package from several small ring bobbins. This conversion process provides one with the possibility of cutting out unwanted and problematic objectionable faults. The process of removing such objectionable faults is called as yarn ‘ clearing'
Practical experience has proven that winding alters the yarn structure.This phenomenon does not affect yarn evenness, but affect the following yarn properties

• Thick Places

• Thin Places

• Neps

• Hairiness

• Standard Deviation of Hairiness
