Embodiment Construction

[0012] like figure 1 and figure 2 Shown, a kind of yak cashmere wraps core-spun yarn, comprises inner core yarn layer and outer wrapping layer, and inner core yarn layer comprises core layer yarn 12 and wrapping layer 1, and core layer yarn is filament or short fiber spun yarn, and wrapping layer For the staple fiber strands with weak twist, the staple strands are yak wool strands, the twist of the staple spun yarn of the core layer is far greater than the twist of the staple strands of the wrapping layer, and the outer wrapping layer wraps the first yarn 2, The second yarn 3, the third yarn 4 and the fourth yarn 5, the first yarn, the second yarn, the third yarn and the fourth yarn are identical yarns, the first yarn, the second yarn, the third yarn and the fourth yarn The yarn is filament or staple spun yarn, the first yarn is twisted in S direction and the second yarn is twisted in Z twist direction first to go around the rear side of the inner core yarn layer and intertw...

Abstract

The invention provides a yakwool-wrapped core-spun yarn and a production method thereof. The yarn comprises an inner core yarn layer and an outer wrapping layer, the inner core yarn layer comprise core layer yarns and short fiber coating yarns with weak twists, and the outer wrapping layer is crossly wrapped by utilizing four yarns; during yarn spinning, two layers of arranged yarn cones are additionally mounted on a hollow spindle, thereby achieving cross wrapping of the four yarns to the inner core yarn layer. By utilizing the production method provided by the invention, the cross wrapping of the four yarns of the inner core yarn layer can be achieved, thereby improving the yarn formation quality, enriching the appearance styles of the yarns, and improving the product additional value.

Description

technical field [0001] The invention relates to the field of spinning new technology, in particular to a yak cashmere wrapped core-spun yarn and a production method thereof. Background technique [0002] Parallel spinning, also known as wrapping spinning, uses a hollow spindle for spinning, and the yarn produced by a parallel spinning machine is called parallel yarn, also known as P.L yarn. In parallel spinning, a non-twisted parallel fiber strip is used as the core yarn, and the outsourcing filament or spun staple yarn is wound on the bobbin after being wrapped into yarn. Since the fibers of the core yarn are not twisted, it is called Parallel spinning. When the yarn is stretched, the filament exerts radial pressure on the short fiber sliver, which causes friction between the short fibers and makes the parallel yarn have a certain strength. [0003] Parallel yarn can replace thread, and it is suitable for untwisted, weak twist and pile products with its unique yarn struct...
