Abstract
The invention provides a double-layer wrapped yarn and a production method therefor. The double-layer wrapped yarn comprises an inner core yarn layer and outer wrapping layers, wherein the inner core yarn layer is a staple fiber yarn with a weak twist; the outer wrapping layers include a first wrapping yarn and a second wrapping yarn, wherein the first wrapping yarn is wrapped around the outer side of the inner core yarn layer in a Z twist direction to obtain a single layer wrapped yarn, and the second wrapping yarn is wrapped around the outer side of the single layer wrapped yarn in an S twist direction. During spinning, a staple fiber rough yarn is feed to pass through an upper layer parallel spinning device to realize the wrapping of the first wrapping yarn, and thus the single layer wrapped yarn is obtained; then the single layer wrapped yarn passes through a lower layer parallel spinning device to realize the wrapping of the second wrapping yarn, so that the double-layer wrapped yarn is obtained. With the method, double wrapping of the inner core yarn layer can be realized and further the yarn forming quality is improved; the outer wrapping layers can be of different colors and materials, so that the appearance styles of the yarn can be added and the added value of the product is increased.
