Thread bundling and tip twisting based spinning method and spinning device

Abstract

The invention relates to a thread bundling and tip twisting based spinning method and spinning device. A first gathering device and a second gathering device are pressed on a rotary rubber roller device; thread tooth tips on the surfaces of gathering grooved wheels of the first gathering device and the second gathering device penetrate into input loose fibers and split fibers; meanwhile, right-hand threads and left-hand threads which are arranged in a left-right manner push the loose fibers to be sequentially gathered towards a gathering groove and a U-shaped groove in the middle respectively; the bundled fibers are driven by surface friction of a tip twisting device rotating at a high speed in the U-shaped groove to be twisted and entangled; and the fibers are arranged to be inclined and mutually twisted and entangled; the bundled fibers with the twisting strength are formed at the twisting tip and are collected on a winding device after being drafted by an output roller device, so that the loose fibers are axially pushed by the threads to form bundles, and the bundled fibers are directly twisted and formed into yarns through friction of high-speed rotation. The spinning efficiency is high, the pre-spinning procedure is greatly shortened, the operation is easy, and the popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning method and a spinning device with thread bundle and tip twisting. Background technique [0002] Ring spinning technology belongs to grip-end spinning. During the ring spinning process, when the bobbin winds the yarn, the traveler is driven to rotate around the steel ring to twist the sliver. The traditional ring spinning twist During the process, the twist is generated by the movement of the traveler, and the twist is transmitted from bottom to top to the twisting point. Ring spinning technology is widely used because of its strong adaptability of raw materials, wide range of production varieties, and high yarn quality. However, it also has disadvantages such as low spinning efficiency, complicated production process, difficult quality control, and high quality requirements for pre-spinning. [0003] New spinning is a new spinning technology that is different from tr...

Problems solved by technology

[0006] Although these new spinning technologies have overcome the low efficiency of ring spinning and the difficulty of achieving large packages, they still need to be spun through strands. The spinning process is not significantly shortened, and high-quality strands are required. Spinning with sliver, which has great requirements on the pre-spinning process, it is difficult to realize the revolutionary breakthrough of direct spinning of loose fiber
