Problems solved by technology

The existing hanging dyeing makes the fabric appear multi-color superimposed level changes along the warp direction, which increases the waste when the fabric is used as clothing, curtains, home furnishing, and bedding, which is not conducive to the actual use of the fabric
However, the multi-color superposition effect of spray dyeing has the problems of long dyeing time and low color fastness, which increases the cost of fabric dyeing.
[0003] In the prior art, although there is the idea of ​​overlapping multiple dyed areas, there are the following difficulties in actual operation: firstly, the area of ​​the dyed area is difficult to control, resulting in the difference in the area of ​​the dyed area between different batches of the actually obtained fabric. differences, it is difficult to meet customer needs
Secondly, the existing multi-color superimposed dyeing usually has an obvious band-like distribution, and the color difference between adjacent dyed areas is obvious, and there is no excessive color effect
Finally, in the prior art, when multiple dyed areas are superimposed, the repeatedly superimposed dyed areas are dyed with different colors for multiple times, and the colors of the finally repeatedly superimposed dyed areas are mostly dark black, dark brown, and dark gray. Affects the overall color effect of the fabric

Embodiment 1

[0065] Embodiments 1 to 5 are specific implementations of the multi-color superposition dyeing process using a dyeing jigger in the present invention. Wherein embodiment 1 is the best embodiment. In order to reduce the variables of the process operation, so as to perform performance comparison, the fabrics used in Examples 1 to 5 are wide-width silk-cotton fabrics interwoven with silk fibers and cotton fibers and a width of 330 cm. The fabrics used in Examples 6 to 8 are wide-width silk-cotton fabrics interwoven with silk fibers and cotton fibers and a width of 300 cm. The reactive dyes used in Examples and Comparative Examples are all vinyl sulfone type reactive dyes.

[0066] Example 1

[0067] This embodiment is the dyeing effect of multi-color gradient color: use the first dye solution to dye light pink, use the second dye solution to dye pink; The area of ​​the dyeing area of ​​the second dyeing solution gradually decreases; the width ratio of the first dyeing area a...

Embodiment 2

[0087]This embodiment shows the dyeing effect of multi-color gradient colors: use the first dye solution to dye light pink, use the second dye solution to dye pink, use the third dye solution to dye rose red, and use the fourth dye solution to dye bright red; There are four gradual changes from light to dark; the width ratio of the dyeing area of ​​the first dyeing liquid, the second dyeing liquid, the third dyeing liquid and the fourth dyeing liquid in the width direction of the fabric is 4:3:2:1; The dyed area of ​​a dye liquor covers the entire fabric width in the fabric width direction. The process steps in this embodiment include sorting and winding, marking the liquid level, preparing the first dye solution and dyeing, cleaning, preparing the second dye solution and dyeing, cleaning, preparing the third dye solution and dyeing, cleaning, preparing the fourth dye solution and Dyeing, cleaning; specific operations are as follows:

[0088] Finishing and rolling: Finish and...

Embodiment 3

[0105] This embodiment is the dyeing effect of multi-color gradient colors: the dyeing effect of evening red-pink-pink-evening red is presented in the width direction of the fabric. The first dyeing solution is used to dye pink, and the second dyeing solution is used to dye evening red, with a symmetrical two-stage gradient effect from light to dark. The gradient effect is symmetrical to the center line of the fabric width, and the center line of the fabric width is parallel to the warp direction of the fabric. . The width ratio of the dyed region of the first dye solution to the dyed region of the second dye solution in the width direction of the fabric is 2:1.

[0106] The process steps in this embodiment include sorting the rolls, marking the liquid level, preparing the first dye solution and dyeing, cleaning, preparing the second dye solution and dyeing, cleaning, rearranging the rolls, preparing the first dye solution and dyeing, cleaning, and preparing The second dye so...

Abstract

The invention relates to a multi-color overlay dyeing process of a wide-width silk-cotton fabric, which belongs to the technical field of fabric dyeing. A pad (5) is placed on one end of the bottom of the machine base (1), and the dyeing tank (4) is inclined at an angle of 5°~35° with the horizontal direction; the outside of the dyeing tank (4) is equipped with a batching bucket (6). The dyeing jigger can be used for wide-width silk-cotton fabric rolls to form multi-color superposition effects, and the waste water discharge is significantly reduced. The multi-color superposition dyeing process of wide-width silk cotton fabric can realize multi-color gradient dyeing, multi-color gradient dyeing with symmetrical effect, and multi-color superposition without gradient effect. The superimposed area can maintain bright colors and can obtain Novelty visual effects; the jigger can significantly reduce waste water discharge.

Description

technical field [0001] The invention relates to a multi-color overlay dyeing process of a wide-width silk-cotton fabric, which belongs to the technical field of fabric dyeing. Background technique [0002] Since different colors can be superimposed and dyed to form a new color, a third different color can be obtained after dyeing a fabric of one color with another color dye, for example, yellow and blue are superimposed to form green, Red and blue are superimposed to form purple, and superimposed and multiple colors can be obtained on the fabric through the superposition of colors. In the prior art, the jigger can only be used to dye the fabric into a single color, and it is impossible to use the jigger to dye multiple colors. It is even more impossible to realize the change of the dyeing area. At present, when multiple colors are superimposed, hang dyeing or spray dyeing is often used. The dyeing efficiency of these two types is low, and both hang dyeing and spray dyeing ...
