1. Change the package to increase the yarn capacity of the yarn package: Connect the bobbins (or hanks) with a smaller capacity through the winding to form a bobbin with a larger capacity. The capacity of one bobbin is equivalent to more than twenty Only bobbin. The package can be used for warping, twisting, weft rolling, dyeing, weft yarn on shuttleless looms and knitting yarn. If the bobbins are directly used in these processes, it will cause excessive downtime, which will affect the improvement of production efficiency and also affect the improvement of product quality. Therefore, increasing the package capacity is a necessary condition for improving the productivity and quality of the subsequent processes. 2. Remove the defects on the yarn and improve the quality of the yarn: There are some defects and impurities in the yarn produced by the cotton spinning mill, such as thick knots, details, double yarn, weak twist yarn, neps, etc. During winding, the yarn clearing device is used to inspect the yarn to remove defects and impurities on the yarn that affect the quality of the fabric, improve the uniformity and smoothness of the yarn, and help reduce yarn breakage in the subsequent process , Improve the appearance quality of the fabric. It is reasonable for the defects and impurities on the yarn to be removed in the winding process, because the work of each package is carried out independently during the winding process. When a certain package is broken, the other packages can continue to work without being affected. Process requirements for winding: 1. The winding tension is appropriate and does not damage the original physical and mechanical properties of the yarn. 2. The bobbin package has a large capacity, good shape, and easy unwinding. 3. The yarn joints are small and strong, and try to form knotless yarns. 4. The bobbin used for warping should be of fixed length, and the bobbin used for dyeing should have a uniform structure (even roll density). 1.
