Technical Field

The invention belongs to the field of textile yarn preparation, and particularly relates to a method for preparing segment-color slub yarn.

Background

With the improvement of living standard, people are no longer limited to the attention of basic functions of clothes (such as warm keeping, sun protection, shading, protection and the like), and begin to pay more attention to the dimensions of style, color, function, health care and the like. Based on such a large background, the basic yarns (mainly, conventional plain yarns) constituting the clothes cannot meet the requirements of people, and various fancy yarns are produced at the same time. The fancy yarn can be made into products with different performances, styles and appearances according to the characteristics of the performances, the structures, the appearances and the like of the respective raw materials.

Fancy yarns can be generally classified into fancy yarns and fancy yarns. The common fancy yarn emphasizes that the fibers of various colors are mixed uniformly, and the fiber distribution of various colors of each section of the yarn is basically consistent. The biggest difference between the segment-color slub yarn and the common fancy yarn is that new fibers are embedded into the yarn in the longitudinal direction, so that the yarn is rich in color change in the longitudinal direction, and the area of the longitudinal yarn is increased, namely slubs. Because the segment-color slub yarn on the market at present has the defects of single color and component, the segment-color slub yarn has great limitation in popularization, can only be used for common textile fabrics and cannot weave high-grade textile fabrics with various styles. Aiming at the problems, the patent provides a preparation method of segment-color slub yarns.

The appearance of the segment-color slub yarn presents nubs with equal or unequal pitches and has regular colors. The preparation method of the segment-colored slub yarn mainly comprises the following steps: 1) a digital slub yarn production device is additionally arranged on a ring spinning frame, the speed of a middle roller is controlled by a main servo motor to change, the speed of a rear roller is independently controlled by a segment color servo motor to change, the segment color slub yarn is spun by a method of controlling the middle roller and the rear roller to change speed and overfeed, and the total draft multiple required by the spinning frame is the front zone draft multiple of the spinning frame before modification. The production of the segment-color slub yarn is mainly realized by reforming a transmission system of a ring spinning frame; 2) the digital spinning machine adopts a nested design, the jaw of a back roller for controlling the original fiber feeding is changed into 3 jaws from a single jaw, and 3 back rollers are driven by servo motors controlled by respective programs, so that a plurality of pieces of roving are fed at different speeds. 3 rear rollers controlled independently feed 3 strands of rough yarns at different speeds, and the rough yarns are subjected to independent rear zone drafting and common front zone drafting and then are converged and twisted to form yarns. Due to the lack of segment-color slub yarns with variable colors and styles in the market, a preparation method of a novel segment-color slub yarn is urgently needed.
