Core yarn neatening entwisting parallel spinning device

Abstract

The invention provides a twisted parallel spinning device for core yarn finishing, which includes an upper hollow spindle and a lower hollow spindle. The upper and lower hollow spindles are interconnected through bearings. The hollow spindle is equipped with a yarn bobbin through a tray, and the outsourcing yarn is wound on the yarn bobbin, and the lower hollow spindle is driven by a motor through a fixedly connected belt pulley. During spinning, the staple fibers after drafting pass through the yarn guide wheels of each yarn guide device in an S-shaped route. By controlling the opening and closing of the bearings, the upper hollow spindle follows or does not rotate with the lower hollow spindle, and then Realize the finishing or twisting of staple fiber strands. The invention can realize finishing before the core yarn is wrapped by the outer covering yarn, or realize twisting of the core yarn before being wrapped by the outer covering yarn, thereby improving the yarn quality.

Description

technical field [0001] The invention relates to the new technology field of spinning, in particular to a core yarn finishing twisted parallel spinning device. 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 structure, giving peo...

Problems solved by technology

However, the current parallel spinning devices are all outsourced with single filament or spun yarn, which limits the variety of spinning and yarn quality.
