ANALYSIS OF THE PROCESS SIZING OF WARP YARN

The surface of some fibers, especially spun yarns, is fluffy because the ends of the fibers protrude from the core. During weaving, the yarns are subjected to various mechanical effects. As a result of the formation of the humus, the tension of the threads increases, they are rubbed, stretched and bent under the influence of the scales, lamellae, flowers and the movement of the blade. As a result of these effects, the fibers that make up the yarn shrink, some of the fibers fall off, resulting in a decrease in the abrasion resistance of the yarn in the body, which increases the likelihood of its breakage.
