Problems solved by technology

However, because the dye used in dyeing is not an ideal dye, that is to say, the ideal yellow dye should completely reflect the visible light of 500-700 nanometers and completely absorb the visible light of 400-500 nanometers, but the act

Embodiment 1

[0046] A method based on CMYKW five-primary-color roving coupling drafting to realize mixed-color spinning, specifically comprising:

[0047] 1) The drafting and twisting system includes front rollers, middle rollers and combined rear rollers arranged front and rear; the combined rear rollers have five rotational degrees of freedom, which include the first rear roller and the second rear roller arranged side by side on the same rear roller shaft. roller, the third rear roller, the fourth rear roller and the fifth rear roller; the first rear roller, the second rear roller, the third rear roller, the fourth rear roller and the fifth rear roller respectively at speed V h1 , V h2 , V h3 , V h4 and V h5 Movement; front roller at speed V q sports;

[0048] 2) The first rear roller, the second rear roller, the third rear roller, the fourth rear roller and the fifth rear roller are respectively drafting five basic color yarns of yellow, magenta, cyan, black and white; keep the fr...

Embodiment 2

[0067] A device for mixed-color spinning based on CMYKW five-color roving coupling drafting, which includes a control system and an actuator. The actuator includes a five-component split-and-combine type synchronous two-stage drafting mechanism, a twisting mechanism, and a winding forming mechanism. ; The secondary drafting mechanism includes a primary drafting unit and a secondary drafting unit.

[0068] Such as figure 1 and 2 As shown, the first-stage drafting unit includes a combined rear roller 15 and a middle roller 3; the combined rear roller 15 has five rotational degrees of freedom, and includes the first rear roller 6 and the second rear roller arranged side by side on the same rear roller shaft 20 8. The third rear roller 10, the fourth rear roller 12 and the fifth rear roller 14; the five rear rollers are arranged adjacently in sequence, and their driving mechanisms are arranged on both sides of the five rear rollers; the secondary drafting unit includes the front ...

Abstract

The invention discloses a mixed color spinning achievement method and device based on five primary color CMYKW rough yarn coupling drafting. The method and device specifically comprise that a drafting and twisting system includes a front roller, a middle roller and a post-combination roller arranged front and back; a first rear roller, a second rear roller, a third rear roller, a fourth rear roller and a fifth rear roller arranged in parallel on the same rear roller shaft of the post-combination roller draft yarn of the colors of yellow, magenta, cyan, black and white respectively; the speed V[q] of the front roller is kept constant, the speeds of the first rear roller, the second rear roller, the third rear roller, the fourth rear roller and the fifth rear roller are adjusted, and then the color matching of the yarn is achieved; during color mixing, the black yarn is used for adjusting the color depth or saturation of colored spun yarn, the white yarn is used for adjusting the color density or brightness of the colored spun yarn, and different proportions of white and black are used for obtaining a variety of different hues. According to the mixed color spinning achievement method and device based on the five primary color CMYKW rough yarn coupling drafting, the color defect of the colored spun yarn in an existing technology is overcome by introducing black and white, so that the ideal color effect is further obtained.

Description

technical field [0001] The invention relates to the field of spinning in textile engineering, in particular to a method and a device for realizing mixed-color spinning based on CMYKW five-primary-color roving coupling drafting. Background technique [0002] Color spinning is to selectively mix colored fibers (dyed fibers or liquid dyed fibers), and then spin them into colored yarns with a certain color. Use this colored yarn for yarn-dyed weaving, and form color distribution on the fabric by mixing colors, such as grid fabric, jacquard fabric and other cloth surface effects. [0003] There are two traditional color spinning processes, one is to make slivers of different colors by pre-spinning mixed colors, and then the spun yarn is drawn and twisted to form melange yarns; the other is to draw two different colored rovings by drafting The middle and rear rollers of the mechanism are fed separately, and one of the rovings is unevenly drafted, and then merged and twisted to fo...
