    As competition intensifies and textile exports increase, textile companies are increasingly concerned about product quality, especially yarn and fabric properties. For a long time, fabric defects have been plagued by the process of weaving, knitting and dyeing. During the weaving process, the appearance of wool and breakage will not only greatly affect the efficiency of weaving, but also greatly increase the weaving of the fabric, which will affect some of the main fabrics. Performance, such as surface smoothness, feel and friction.
     
    Main factors:
     
    1. The physical and mechanical properties of raw materials are not ideal, the fiber breaking strength is low, the elongation at break is small, and the CV value of the unevenness is too high. Although the sizing process can not make up the defects of the raw materials itself after sizing, the warp cohesion is poor. In the weaving process, it can not withstand the repeated friction of the steel shovel and the heald, which causes the warp yarn to fluff or break.
     
    2. Warping, pulping, and shaft process yarn guides are grooved, damaged or warp yarns are shaken and entangled, so that the fiber strength and elongation are damaged, the mechanical properties are deteriorated, and the production and processing tension exceeds its strength. When the yield value of elongation is increased, the single fiber is broken and broken.
     
    3. The looms of the looms, the healds of the healds, the damage, the warp yarns can not withstand repeated high frequency friction and the hair breaks. The faster the speed of the loom, the more severe the warp.
     
    4. The warping machine's hairline monitor fails, so that the raw material's own wool, long knots escape or the blocker is too large and too long when the joint is broken. When the weaving, the warp yarns are entangled, resulting in unclear openings. Pull the broken head.
