5 Steps to Gradient Dyeing of Yarn
No.1 Seal Festival
According to the design requirements, a small section (such as 0.5-1cm) of color is printed at every set distance on the spread hank, which can be the same color, but most of them are five colors. It must be noted that the spacing must be irregular and unequal, otherwise “turtle back” or “landscape painting” will appear on the canvas.
No.2 segment dyeing
A number of dyes are dripped on different parts of the spread skein at the same time, and after vacuum suction or rolling, the color is fixed and washed. Compared with the knuckle, the color segment is longer, the white yarn spacing is smaller, and even two adjacent colors will appear “color-blocking” on the yarn. Space dyed yarn is used more in knitted fabrics.
No.3 Tie Dyeing
Tie the part of the skein tightly with a rope (or wrap it with plastic film), and then carry out dip dyeing. As a result, the tightly tied part is left blank, and there is some bleeding from deep to light in the bundled part. The unbundled part is uniformly colored, and the product is different. There is flavor.
No.4 Printing (Printing)
This method is generally used to produce warp woven fabrics. The pattern is printed on the warp yarn (not on the weft yarn), and the product style is hazy, like a flower but not a flower. When printing the warp, you can first fake weave (knitting method is first printing and then warping, weaving method is warping – fake weaving – printing), basf af 32 pe wax tds, or you can directly print on the warp yarn, such as synthetic fiber warp yarn can be printed on the transfer printing machine.
No.5 Gradient dyeing
Gradient dyeing (colorful silk) dips different parts of the skein (silk) in the dye solution for different times, so that each frame of yarn presents a gradient color from light to dark without obvious boundaries, such as traditional Chinese embroidery seven-color silk thread. In addition, there are half-edge dyeing, jet dyeing, single yarn continuous dip dyeing, etc.
