A three-filament wrapping parallel spinning yarn, spinning device and spinning method

Abstract

The invention provides three-filament twisting parallel spun yarn, a spinning device and a spinning method. The yarn comprises an inner core yarn layer and an outer twisting layer, wherein the inner core yarn layer comprises weakly twisted staple fiber yarn or combination of staple fiber yarn and core yarn; the outer twisting layer comprises three strands of twisting yarn and two strands of twisting yarn; the inner core yarn layer is subjected to twisting processing by the outer twisting layer to finally obtain the needed yarn. When in spinning, three yarn cylinders arranged up and down are additionally mounted on a hollow spindle, and the yarn cylinders and the hollow spindle are connected through controllable gears, so that the controllable feeding of the three strands of twisting yarn can be realized. Through the adoption of the method, the controllable twisting of the three strands of yarn of the inner core yarn layer can be realized, so that the resultant yarn quality can be improved, the appearance style of the yarn can be enriched, and the added value of the product can be improved.

Description

technical field [0001] The invention relates to the field of spinning new technology, in particular to a three-filament wrapping parallel spinning yarn, a spinning device and a spinning method. 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 it...

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.
