Dope dyed yarn special dyeing method
Like fabrics, yarns are also partially dyed, such as knots, segment dyeing, tie dyeing, printing, discharge, and grading.
1, the festival
According to the design requirements, a small section (such as 0.5 ~ 1cm) color is printed on the spread skein at a set distance, which can be the same color, but most of them are five colors. It must be noted that the spacing must be irregular and not equidistant, otherwise "turtle" or "landscape painting" will appear on the cloth surface.
2, segment dye
A plurality of dyes are simultaneously dripped on different parts of the spread skein, and after vacuum suction or rolling, the color is fixed and washed. Compared with the printed sections, the color segments are longer, the white yarn spacing is smaller, and even the adjacent two colors will appear "color matching" on the yarn. Segment dyed yarns are used more on knitted fabrics.
3, tie dye
The part of the skein is tied with a rope (or a plastic film), and then dip-dyed. As a result, it is left white at the tightness, and the part of the tying has a deep to light bleed, and the unbundled portion is uniformly colored. Have a charm.
4, printing (printing)
This method is generally used to produce a printing machine fabric. The pattern is printed on the warp yarn (not printed on the weft yarn), and the product style is ambiguous. When printing, the weaving can be faked first (the knitting method is first printing and then warping, the weaving method is warping - fake weaving - printing), and it can also be printed directly on the warp yarn. For example, the synthetic fiber warp yarn can be printed on the transfer printing machine.
5, gradient dyeing (seven colors)
Different parts of the skein (silk) are dipped in the dyeing liquid for different times, so that each frame yarn has a gradual color with no obvious boundary from shallow to deep, such as Chinese traditional embroidered seven-color silk thread. In addition, there are half-side dyeing, spot dyeing, continuous dyeing of single yarns, and the like.
