A kind of two-for-one twist spinning method

Abstract

The invention relates to a two-for-one twist spinning method, which belongs to the technical field of textiles. In the present invention, a two-for-one twisting winding mechanism is arranged in front of the drafting system of the spinning frame. The two-for-one twisting and winding mechanism is composed of a two-for-one twisting mechanism and a winding mechanism. The winding mechanism is located in the yarn storage tank of the two-for-one twisting mechanism. After being output by the front roller nip, the yarn is twisted to form a yarn sliver. The yarn passes through the yarn guide hook, enters the yarn inlet pipe, the yarn running channel, and the yarn outlet tube, and runs to the tensioner. Under the action of the rotation of the twist disc, the sliver running from the nip of the front roller to the tensioner section obtains 2n twists per minute. Under the action of the tensioner, the sliver is drawn out from the yarn outlet bobbin with equal tension, and then passes through the winding groove The bobbin is wound to form a bobbin package. The present invention changes the ring twisting and bobbin winding methods of ordinary spinning frames, adopts two-for-one twisting spinning, greatly improves twisting efficiency, spinning quality and uniformity; adopts bobbin winding method, increases spun yarn packages, Increase productivity.

Description

technical field [0001] The invention relates to a spinning method, in particular to a two-for-one twist spinning method, which belongs to the technical field of textiles. [0002] technical background [0003] Spinning is the process of orderly arranging the messy loose fibers in sequence, such as opening, carding, drafting, etc., and then performing linear convergence and twisting. Different twisting methods directly determine the structure and efficiency of the yarn produced by spinning. Usually, the twist spinning forms are divided into two types: holding end twisting and free end twisting. Twisting at the holding end can limit the control of fiber strands for mandatory cohesion and twisting, and has the advantages of high cohesion between fibers, high yarn strength and good wear resistance, such as ring spinning technology with large quantity and wide range twisted form. However, the speed of ring spinning is low, generally more than ten meters per minute. The main rea...

AI Technical Summary

Problems solved by technology

The technology of this device is essentially to add a drafting mechanism and a roving hanging mechanism to the yarn storage tank on the stationary spindle of the two-for-one twisting mechanism; because the roving package is long and the drafting system is complicated, the device is difficult to operate when spinning. The large yarn balloon affects the yarn quality, resulting in poor practicability and low application and promotion value of this technical device

Therefore, there is currently no technology to solve the contradiction between high-speed spinning and twisting of spun yarn and high-quality production, and the technical problem that the spinning frame cannot be packaged.
