Spandex coated yarn winding process and method

The invention relates to the technical field of spandex coated yarns, and provides a spandex coated yarn winding process and method, and the method comprises the following steps: firstly, arranging polyester fibers and spandex yarns in parallel; then guiding the gas jet to the polyester fibers, and separating filaments in the polyester fibers; then, filaments in the polyester fibers and filaments in the spandex filaments are mixed through gas jet, and mechanical friction points are formed; then filament yarns in the polyester fibers are wound into the moving spandex yarns, and finally, the wound spandex coated yarns are subjected to heating treatment. The gas jet technology adopted by the invention not only can effectively separate the filaments in the polyester fibers, but also can maintain the original characteristics and quality of the fibers, and meanwhile, more uniform coverage and better fiber distribution can be realized by winding the filaments in the polyester fibers into the moving spandex yarns, so
