Winding machine is a special equipment in textile industry. Winding, as the last process of spinning and the first process of weaving, plays the role of "bridge" connecting the preceding and the following, so it occupies an important position in the textile field.
Main tasks of winder:
1. Change the package and increase the volume of yarn: Connect the less capacity yarns (or hanks) through winding, and make the bigger package. The capacity of one package is equal to more than twenty tubes. The bobbin can be used for warping, twisting, weft winding, dyeing, weft on shuttleless looms and knitting yarns. If these processes use the yarn directly, it will cause too much stop time, affect the improvement of production efficiency, but also affect the improvement of product quality. Therefore, increasing the volume of package is a necessary condition to improve the productivity and quality of the later process.
2. Eliminate yarn defects and improve yarn quality: There are some defects and impurities in the yarns produced by cotton spinning mills, such as slubs, details, double yarns, weak twist yarns, neps and so on. When winding, yarn clearing device is used to check the yarn, remove the defects and impurities that affect the quality of the fabric, improve the uniformity and finish of the yarn, so as to reduce yarn breakage in the later process and improve the appearance quality of the fabric. It is most reasonable that defects and impurities in yarn are removed in winding process, because the work of each cylinder is carried out independently in winding process, and other cylinders can continue to work unaffected in dealing with broken ends in one cylinder.
Process requirements for winding:
1. Proper winding tension does not damage the original physical and mechanical properties of the yarn.
2. The drum has large volume and good shape, so it is easy to unwind.
3. Yarn joints are small and firm, forming knotless yarns as far as possible.
4. The tube used for warping should be fixed length, and the tube used for dyeing should be uniform in structure (even rolling).
