A kind of thread multi-color processing device

Abstract

The invention discloses a processing device for one yarn with multiple colors. The processing device comprises a yarn feeding mechanism, a preprocessing mechanism, a drawing and stretching mechanism and a take-up mechanism, wherein an etching device is arranged between the yarn feeding mechanism and the preprocessing mechanism; the etching device consists of two or more etching grooves which accommodate etching solutions of different concentrations; yarn guide rolls are mounted at two ends of each etching groove; yarn pressing rotary drums are arranged under the yarn guide rollers and in the etching grooves; the drawing and stretching mechanism comprises two drawing and stretching structures which are first drawing and stretching structures or second drawing and stretching structures, and each drawing and stretching structure comprises a drawing and stretching roller and a pressing wheel which are mutually matched; the drawing and stretching rollers of the first drawing and stretching structures, or the drawing and stretching rollers of the second drawing and stretching structures generate intermittent tension through moving up and down. The drawing and stretching rollers of the upper and lower drawing and stretching structures generate the intermittent tension through moving up and down, so that a part of fibers of the yarns are snapped or generate stress rupture, the color staining capacity of the part of the fibers of the yarns is changed, and the color effect of different shades is presented during follow-up color dyeing, so that the purpose that one yarn has multiple colors can be realized.

Description

technical field [0001] The invention relates to a yarn processing device, in particular to a yarn multi-color processing device. Background technique [0002] Textiles should show multi-color effects. Generally, yarns of different materials are woven and dyed. Because of the different colors of the yarns, the dyed colors are different, showing multi-color effects on textiles, but on a single yarn. It is a uniform color. At present, there is no trace of dyeing that can have a variety of shades of color. [0003] At the same time, the color fastness of textiles refers to the degree of firmness of textiles subjected to external factors during use or processing, and the color may become darker, lighter or change in hue; in the current textile dyeing technology, the color fastness of textiles It is mainly related to the selected dye and dyeing process. The color fastness of textile dyeing mainly depends on the choice of dye, and there is a lack of direct treatment of yarn to inc...

[0003] At the same time, the color fastness of textiles refers to the degree of firmness of textiles subjected to external factors during use or processing, and the color may become darker, lighter or change in hue; in the current textile dyeing technology, the color fastness of textiles It is mainly related to the selected dye and dyeing process. The color fastness of textile dyeing mainly depends on the choice of dye, and there is a lack of direct treatment of yarn to increase the color fastness of textiles.
