[0002] Cotton yarn is a continuous fiber bundle made of cotton as raw material through a spinning process, is a basic material of the textile industry, and is widely used in the fields of clothing, home textiles and industrial cloth. Cotton yarn is called cotton thread after plying. According to different spinning processes, cotton yarn can be divided into carded yarn and combed yarn. 1. Carded yarn: the yarn is spun from cotton fibers through a normal spinning system. 2. Combed yarn: the yarn is spun from cotton fibers through a combed spinning system. Combed yarn selects high-quality raw materials, and the fibers in the yarn are straight and parallel, have few impurities, good luster, uniform evenness and high strength. Such cotton yarn is mostly used for weaving high-grade fabrics. In the cotton yarn processing process, drying treatment can remove excess moisture in the cotton yarn, reduce the risk of mold in the storage and transportation process of the yarn, improve the strength and stability of the yarn, reduce the broken ends and hairiness, and thus improve the quality of the yarn. Therefore, a drying device is needed. In the related art, a drying machine for cotton yarn processing is disclosed in Chinese patent application No. CN112556348A. The drying machine includes a bottom plate, four rectangularly distributed support columns fixed to the bottom outer wall of the bottom plate, a fixed box fixed to one side of the top outer wall of the bottom plate, an opening formed in one side of the outer wall of the fixed box, equidistantly distributed drying boxes fixed to the bottom inner wall of the fixed box, an electric sliding rail fixed to the middle of the bottom inner wall of the drying box, a placement plate fixed to the top outer wall of the sliding part of the electric sliding rail, and a placement component fixed to the top outer wall of the placement plate. The above scheme can utilize the heat generated during drying. The water vapor can be discharged into the L-shaped fixed pipe through the single exhaust valve, and then the L-shaped fixed pipe can discharge the water vapor into the heat collecting box. The heat carried by the water vapor can be absorbed by the multiple temperature guide plates and transferred to the water tank to heat the water in the water tank. The heat generated during the entire drying process is fully utilized, and energy is saved.
