In this study, we used an experimental design to investigate the influence of the total draft, break draft, the distance between the aprons (Clips) and production roller pressure on yarn quality in order to obtain optimum drafting conditions for polyester and viscose (PES/CV) blend yarns in ring spinning frame. We used PES fibres (1.4 dtex × 38 mm long) and CV fibres (1.6 dtex × 38 mm long) to spin a 20 Tex blend yarn of PES (70%)/CV (30%) blend ratio.

When the break draft, adjustment of distance between of aprons and roller pressure is not reasonable, controlling and leading of the fibres is not sufficient for proper orientation of the fibres in the yarn structure to produce a high-quality yarn. Experimental results and statistical analysis show that the best yarn quality will be obtained under drafting conditions total draft of 38, 1.2 break draft, 2.8 mm distance between of aprons and maximum pressure of the production top roller (18daN).

Arrangement and Schemtics of Ring Spinning

Ring-Spinning, Yarn / / / 1 Comment

The traveller speed in a ring frame is the main limitation in achieving higher spindle speed because of the frictional resistance of traveller over the ring flange. The design, metallurgy, surface finish and breaking-in of the rings decide the speed at which a ring frame can be run without excessive end breaks. It is important to understand the schematics of the ring travellers in order to achieve maximum productivity from the ring spinning machines.

Types of Yarn Winding

Ring-Spinning, Yarn / / / 2 Comments

There are two types of winding machines: precision winders and drum winders. Precision winders, used primarily for filament yarn, have a traverse driven by a cam that is synchronized with the spindle and produces 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.

The chief function of the simplex frame is the attenuation of sliver. Insertion of protective twist in order to hold the fine strand of silver. Winding of roving into a package that can be transported, sorted, donned on ring spinning machine.After carding the cotton is passed through draw frames. The draw frame draws the cotton into thick strands.These are then spun into thinner strands on the simplex frame spindles. The output of the simples frame is fed to the ring frame spindles which complete t
