A spinning device and spinning method with full control of fibers in the drafting zone

Abstract

The invention provides a whole-process control spinning device for fibers in a drafting area and a spinning method. The spinning device comprises a rear drafting roller pair composed of a rear rollerand a rear rubber roller, a middle drafting roller pair composed of a middle roller and a middle rubber roller and a front drafting roller pair composed of a front roller and a front rubber roller. Rotating rollers are additionally installed at the front portion of the rear roller, the front and rear portions of the middle roller and the rear portion of the front roller, wherein the left and rightends of each rotating roller and the corresponding roller keep rotating synchronously; the rotating rollers or the rollers are connected with the adjacent rotating rollers through leather rings, extension friction force boundaries for effectively controlling the fibers in strands from jaws between the rollers and the rubber rollers are formed on the corresponding leather rings located on the rotating rollers accordingly, then the whole process control over the fibers from the low-speed movement during the control of the rear-side friction force boundary to the high-speed movement during the control of the front-side friction force boundary is achieved, the whole speed change process of the fibers can be controlled, the distribution of speed change points is more reasonably controlled accordingly, and dry yarn strips are improved.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a spinning device and a spinning method for full-range control of fibers in a drafting zone. Background technique [0002] Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. Therefore, the improvement of ring spinning technology, especially its twisting process, has always been a hot topic in spinning research, and a series of fruitful research results have been achieved in engineering practice and theoretical research, such as compact spinning, cable spinning , dislocation spinning, etc. In particular, compact spinning technology, which adds a fiber accumulation area in front of the ring spinning frame traction device, enables fibers to be twisted in a parallel and compact state, which is an important reform in the field ...
