Weft winding is a process of rewinding tube yarn, bobbin yarn or skein into a knitting suitable for filling the shuttle chamber.
When winding, yarn tension should be uniform, winding tightly and forming well, so as to avoid weft breakage and weft shrinkage during weaving and increase weft breakage and loom stop time, which will affect the production efficiency of looms.
Weft yarns for weaving are divided into direct weft yarn and indirect weft yarn. The knitted yarn directly spun on the spinning frame is called direct weft yarn. The process flow can be shortened without warp and weft winding. Direct weft yarn is often used to weave general fabrics in cotton and wool textile combined factories. The knitting of warp and weft is called indirect weft. This kind of knitting has good shape, compact winding and larger yarn capacity than direct weft yarn. It is often used in wool, silk, linen and single weaving factories. Cotton textile joint factories are often used to weave high-grade fabrics.
