The color matching of the invention is different from the color matching in the conventional dyeing methods such as dip dyeing, pad dyeing and the like. The color matching of the invention is that in the dyeing process, the diameter of the cheese is increased along with the rotation of the cheese, and the yarn supporting roller can rotate under the driving of the cheese due to the powerful action between the cheese and the yarn supporting roller; the distance between adjacent touch pens and the liquid supply speed of the dye solution are adjusted, the dye solutions with different colors simultaneously and respectively dye different parts of the cheese through the adjacent touch pens, so that the dyeing areas of the adjacent two dye solutions with different colors on the cheese are increased more and more, and finally the dyeing areas of the adjacent two dye solutions with different colors are gradually overlapped to form a transitional composite color, thereby realizing on-line color matching.
The color matching of the invention is not to dye the yarns after mixing and matching the color of the dye solutions with different colors, but the color matching is formed by the dye solutions with two adjacent colors meeting each other and mutually permeating and mixing the dye solutions in the migration process through the migration of the dye solutions in the yarns during the rotation process of the cheese.
The invention relates to an on-line color matching and dyeing method of nylon cheese, which comprises the following steps:
(1) Preparation of dye liquor

(2) Online color matching and dyeing of nylon cheese
During dyeing, the touch pen is contacted with the yarn supporting roller, and the yarn supporting roller is contacted with the cheese. The distance between two adjacent touch pens is adjusted by moving the touch pens left and right, the liquid supply speed is controlled by adjusting the peristaltic pump, and then the width of the color bars on the cheese can be changed, so that two adjacent dye solutions with different colors are gradually overlapped on the cheese in the winding process to form a transitional composite color, and finally, the online color matching is realized, so that the single yarn has a unique style that the colors are alternately presented and have transitional colors.
The dyeing style of the nylon cheese is shown as follows: (1) the dyed cheese has a plurality of groups of colors, including a dye liquor color group and a transition composite color group, wherein the colors of the plurality of groups are alternately distributed; the dye liquor color group is a single color group, the dye liquor color group adopts one of 2-5 different dye liquor colors, the transition composite color group has 1-4 groups, and the color of the transition composite color group is obtained by color matching of two different colors. (2) The color positions of the dye liquor color group and the transition composite color group can be adjusted at will, and the width of the color strip on the cheese (namely the color strip formed by dyeing the cheese with the dye liquor) is respectively as follows: the width of the single dye solution color strip is 0.6-5.0cm, and the width of the transition composite color strip is 0.6-4.5cm. (3) The dyed cheese is unwound and the dyed parts of the yarn, one section of which is formed on a single yarn, are called color sections. The dyed yarn color knots are circularly changed according to the sequence of the dye liquor color, the transition composite color and the dye liquor color, and the width of the color knots can be adjusted. The widths of the dyed yarn color sections are respectively as follows: the dye liquor color pitch width is 5.0-15.0cm, and the transition composite color pitch width is 2.0-12.0cm.
(3) Nylon cheese aftertreatment
And (3) putting the dyed cheese into a high-temperature high-pressure solid type shaping pot, and carrying out color fixing treatment under the high-temperature high-pressure condition by using saturated steam.

Under the same other conditions, the smaller the distance between two adjacent touch pens is, the smaller the width of the color bar of the single dye solution is, and the larger the width of the transition composite color bar is; under the same other conditions, the larger the liquid supply speed, the larger the color bar width.
The invention has the following beneficial effects:
(1) The nylon cheese is directly dyed without pretreatment during dyeing; heating and salt addition for dyeing promotion are not needed in the dyeing process, and the normal-temperature salt-free dyeing of the nylon cheese is realized. The dye liquor can be fully utilized, no dye liquor residue exists at the bottom of the dye liquor tank and at the bottom of the temporary liquid storage device, the dyeing water consumption and the auxiliary agent consumption are greatly reduced, and the wastewater treatment cost is greatly reduced; the method has the advantages of simple operation, short dyeing process, high dye-uptake, low production cost, green and environment-friendly dyeing process and the like;
(2) The invention can realize that the same single yarn is dyed with at most 5 different colors and 4 groups of transitional composite colors, and has the style of gradual transition and alternate presentation of color sections with different colors, which cannot be realized by the conventional space dyeing and dip dyeing modes.
