Ring Spinning

spinning spun-yarn yarn The Ring Spinning is the most widely used form of spinning machine due to significant advantages in comparison with the new spinning processes. The ring spinning machine is used in the textile industry to simultaneously twist staple fibres into yarn and then wind it onto bobbins for storage. The yarn loop rotating rapidly about a fixed axis generates a surface referred to as "balloon". Ring frame settings are chosen to reduce yarn hairiness and the risk of glazing or melting the fibre.

Sizing

fabric spun-yarn weaving Sizing is a complementary operation which is carried out on warps formed by spun yarns with insufficient tenacity or by continuous filament yarns with zero twist. It is done with an aim of improving yarn smoothness and tenacity during the subsequent weaving stage. The sizing methods change depending on the type of weaving machine used, on the yarn type and count, on the technician's experience and skill, on the kind of material in progress.

Ring Spinning Pros and Cons

spinning yarn 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 view points of fibres which can be used and the extent of the yarn counts which can be produced.

Winding

yarn The cop which is prepared in the ring frame is not suitable for further processing. So the yarn is converted into the shape of 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, binding speed. This phenomenon does not affect the evenness of the yarn but it affects the properties of the yarn such as thick places, thin places, nep

Winding Calculation and objective

yarn How to do the winding calcutaions is described here .And also the objective of winding is specified.

Types of Winding

yarn Basically, there are two types of winding machines: precision winders and drum winders. Precision widers, used primarily for filament yarn, have a traverse driven by acam that is synchronized with the spindle and produce packages with a diamond-patterned wind. Drum winders are used principally for spun yarns; the package is driven by frictional contact between the surface of the package and the drum.
