A double-wrapped parallel yarn spinning device and spinning method

Abstract

The invention provides a double-wrapped parallel yarn spinning device. The spinning device comprises an upper hollow spindle and a lower hollow spindle, the upper hollow spindle and the lower hollow spindle are connected through gears in a communicated mode, upper yarn drums and lower yarn drums are installed on the upper hollow spindle and the lower hollow spindle through trays respectively, the upper yarn drums and the lower yarn drums are winded around upper outer wrapping yarn and lower outer wrapping yarn, and a belt disc is fixedly connected to the lower hollow spindle and is driven to rotate by a motor. When spinning, a gear is selected as a reversing gear or a same-direction gear or a reversing speed-varying gear, outer wrapping of yarn at the upper part and the lower part is achieved and at the same time wrapping directions and wrapping screw distances are adjusted during the wrapping. According to the double-wrapped parallel yarn spinning device and a spinning method, the double wrapping for core yarn can be achieved, at the same time the two wrapping directions and wrapping density can be adjusted, and therefore the appearance effect of the yarn is enriched, and the added value of the yarn is increased.

Description

technical field [0001] The invention relates to the field of new spinning technology, in particular to a double-wrapped parallel yarn spinning device and a spinning method. Background technique [0002] Parallel spinning, also known as wrapping spinning, uses hollow spindles for spinning, and the yarn produced by parallel spinning machine is called parallel yarn, also known as P.L yarn. In parallel spinning, an untwisted parallel fiber strip is used as the core yarn, and the filament or spun spun yarn is wrapped. Parallel spinning. When the yarn is stretched, the filament exerts radial pressure on the short fiber strands, causing friction between the short fibers and making the parallel yarn have a certain strength. [0003] The parallel yarn can replace the yarn, and is suitable for no twist, weak twist and pile products with a unique yarn structure, giving people a high-end feeling. However, the current parallel spinning devices all use a single filament or spun yarn fo...

AI Technical Summary

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.
