Problems solved by technology

[0002] According to the search, there are many production processes and products related to wrapped yarn, each with its own characteristics. For example, the silk-wrapped composite yarn with the application number of 93205179.0 is a composite silk wrapped with elastic chemical fiber, and elastic fiber is used as the core. There is a silk wrapping layer on its surface, and the core silk does not leak out. The yarn only shows one color of the outer wrapping yarn, and the color tone is single; Twisted yarn is processed by a special device and a double-twisted spindle. After the outer wrapped yarn is wrapped on the core yarn, the two yarns need to be twisted together, and the color of the yarn is not rich enough.
