Magnetic winding type two-for-one twisting spinning method

Abstract

The invention relates to a magnetic winding type two-for-one twisting spinning method, and belongs to the technical field of spinning. A two-for-one twisting winding mechanism composed of a two-for-one twisting mechanism and a magnetic winding mechanism is arranged in front of a drafting system of a spinning frame, and permanent magnets evenly distributed in the circumferential direction are embedded in the outer end faces of a driving rotary disc of an external motor of the magnetic winding mechanism and driven rotary discs at two ends of a winding groove drum correspondingly, the driving rotary disc drives the driven rotary discs to rotate by means of magnetic force, drafted and output fiber strips are subjected to two-for-one twisting under the twisting action of the two-for-one twisting mechanism to be spun into a sliver, and the sliver sequentially enters a yarn inlet pipeline and a yarn channel through a yarn guide hook, is led out of a yarn outlet pipeline through a tensioner and then is wound into cone yarn to be packaged under the winding action of the magnetic winding mechanism. A built-in electric mechanism winding spinning mode of existing two-for-one twisting spinningis changed, the problems that a built-in electric mechanism is low in winding spinning speed and cannot last for a long time are solved, and high-speed and lasting large-package two-for-one twisting spinning production is achieved.

Description

technical field [0001] The invention relates to a two-for-one-twisting spinning method, in particular to a magnetic winding type two-for-one-twisting 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...
