Section coloured yarn and its spinning device and spinning method

Abstract

A segmentally colored yarn is disclosed, which features that in has different colors longitudinally. Its spinning apparatus features that a feed roller behind the third roller, a controller and a driver are additionally used. Its spinning method features that the draft in the primary draft region for the first group of fibres is formed by the fourth roller, the third roller, and the first and the second apron rollers of spinning frame, and the draft in the primary draft region for the second group of fibres is formed by the fourth roller, the third roller, and the first roller and the second apron roller of spinning frame.

Description

technical field [0001] The invention relates to the technical field of spinning. Background technique [0002] For a long time, with the continuous improvement of people's demand for clothing, various colorful clothing fabrics have emerged, from pure spinning of single fiber in the past to blending of multiple fibers, from pure color spinning in the past to blending of multi-color fibers now, and then Coupled with the further development of the dyeing and finishing process, the color, color and layering of the fabric have been greatly improved. Up to now, the spinning process is still based on three-roller underdrawing and ring spinning, and multi-color mixing is still studied in the horizontal combination of fibers. To achieve different colors in the vertical direction of the yarn is the current differentiated fiber. , the research problem of multi-color blended simulation yarn. [0003] There are two types of broken color yarn currently pr...
