Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a cotton yarn plying device for textile yarns. Background Art

[0002] Cotton yarn is a yarn made from cotton fiber through spinning technology, and is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn is yarn spun from cotton fiber through ordinary spinning system. Combed yarn is yarn spun from cotton fiber through combed spinning system. Combed yarn uses high-quality raw materials. The fibers in the finished yarn are straight and parallel, with few knots, good luster, uniform yarn and high strength. This type of cotton yarn is mostly used to weave high-end fabrics. A plying device is required in the processing of cotton yarn. Before plying, the cotton yarn needs to be unwound from the wire roller, and then wound on the winding device after plying. During the unwinding process, the coarseness of the wire roller will gradually decrease, resulting in changes in the tension of the yarn when unwinding, resulting in inconsistent tension of the subsequent yarns involved in plying, which greatly affects the quality of the cotton thread.
