This not only reduces efficiency but also increase the hard wastes. High breakages on looms also lead to increased rejection of fabrics.

A very high elongation leads to bumping of fabric on loom. Impact of yarn features at customer’s end ● ● ● ● ● ● Winding quality: Winding defects result in breakages while unwinding on warping machines and in weft in shuttle less looms.
