Please refer to FIG. 2 , the present application provides a uniform dyeing method, including: step S210-step S230. The uniform dyeing method provided by the present application can use the dyeing device 2 in FIG. 3 to achieve dyeing.

Step S210: Continuously conveying the substrate 21 along the conveying direction.

The conveying direction corresponding to the substrate 21 may be a horizontal direction, a vertical direction, or an oblique direction. In some preferred embodiments, the conveying direction is oblique, from bottom to top.

Wherein, the base material 21 is fabric, but not limited to cloth. Examples of fibers contained in the substrate 21 include natural fibers such as cotton, silk, hemp, mohair, wool, and cashmere; recycled fibers such as rayon and cupro; synthetic fibers such as nylon, polyester, and polyurethane; bi-plied yarns or blended yarn. The base material 21 is obtained by processing the aforementioned fibers into woven or non-woven fabrics. Substrate 21 may be pretreated.

Step S220 : controlling the coloring liquid to be sprayed on at least one surface of the substrate 21 so that the coloring liquid is slightly saturated in the substrate 21 .

As for the coloring liquid, the coloring liquid can be a liquid used for coloring such as dye liquid, ink, pigment or paint. Dyes may include direct dyes, reactive dyes, acid dyes, acid mordant dyes, vat dyes, soluble vat dyes, sulfur dyes, sulfur vat dyes, insoluble azo dyes, cationic dyes, disperse dyes, and the like.

Wherein, spraying can be spraying, spraying or other spraying methods.

The slightly saturated state can be obtained based on the following method: after the base material 21 is fully colored by cylinder dyeing, the ratio of the coloring liquid and the fabric in the saturated state can be determined; based on the ratio of the coloring liquid and the fabric in the saturated state, Determine the numerical range of the ratio of the coloring liquid to the fabric in the slightly saturated state. Wherein, the numerical range in the slightly saturated state may be smaller than the numerical range in the saturated state. Depending on the material of the substrate, the numerical range of the slightly saturated state can be set differently. That is to say, in the slightly saturated state, the coloring liquid has fluidity in the base material 21 , and the coloring liquid does not reach a fully saturated state in the base material 21 . In this case, the coloring liquid can be fully utilized, reducing loss and being more environmentally friendly. In some embodiments, step S320 may include: atomizing the coloring liquid, spraying the coloring liquid based on the first axis, forming a corresponding spraying area 222 on the substrate 21, and taking the length direction of the spraying area 222 as The second axis, the first axis and the second axis have a first preset angle, and the projections of adjacent spraying areas 222 in the direction of the first axis partially overlap.

By treating the coloring liquid, the coloring liquid can be formed into particles, sprayed on at least one surface of the substrate 21, and a corresponding spraying area 222 is formed on the substrate 21, and the spraying area 222 can be understood as the coloring liquid in the form of particles The formation of the formation of the base material 21 distribution range or area. Exemplarily, the spraying of the coloring liquid can be arranged according to the direction of the first axis through the spraying assembly 22 in the form of a spray head, nozzle, etc., and the coloring liquid is atomized by controlling the pressure of the spraying assembly 22, and forming on the substrate 21 The spraying area 222, the length direction of the spraying area 222 is used as the second axis direction, the first axis and the second axis have a first preset angle, so that the projection of the adjacent spraying area 222 on the first axis direction has partially overlapped.

In one embodiment, the first preset angle is 5°˜45°, preferably, the first preset angle is 15°.

Taking the spraying direction of the coloring liquid as the third axis, the third axis has a second preset angle with the gravity method, and the second preset angle is a non-zero included angle. When the conveying mechanism 20 transports the base material 21, it is transported at an angle of 5°-45° to the injection direction of the coloring liquid. The coloring liquid can be in a slightly saturated state, and under the action of gravity, it flows and penetrates toward the cloth feeding end.

Further, the conveying direction of the conveying mechanism 20 and the direction of gravity have a third preset angle, and the third preset angle is greater than or equal to 0° and less than 90°.

In some embodiments, step S320 may include: rolling the slightly saturated substrate 21 through a roll provided with a diffusion structure 243 .

In order to allow the coloring liquid to fully penetrate into the base material 21, in this embodiment, the base material 21 of the coloring liquid in a slightly saturated state on the surface is further rolled by setting a roller with a diffusion structure 243, so that the coloring liquid is in the roller. Under pressure, it can diffuse along the diffusion structure 243 and gradually penetrate to the surface of the substrate 21 .

Further, as mentioned above, when the conveying direction is inclined, from top to bottom, the coloring liquid on the base material 21 will flow to the lower part of the base material 21 under the effect of gravity, and under the pressure of the rollers, The coloring liquid can diffuse along with the diffusion structure 243 and penetrate into the substrate 21 .

Step S230 : Apply pressure to the substrate 21 in slightly saturated state, so that the coloring liquid penetrates into the substrate 21 and the coloring liquid diffuses with the diffusion structure 243 .

In this step, in order to further fully infiltrate the coloring liquid, a certain pressure can be applied to the base material 21 through structures such as rolls, so that the coloring liquid can diffuse more quickly and fully under the action of pressure extrusion. At the same time, setting the diffusion structure 243 on the surface of the roll to guide the distribution and diffusion of the coloring liquid can further improve the penetration uniformity of the coloring liquid.

Please refer to FIG. 3 , which is a schematic structural diagram of a dyeing device 2 provided by an embodiment of the present application. The dyeing device 2 comprises: a conveying mechanism 20 , a spray assembly 22 , a control device 23 and at least one redistribution mechanism 24 .

The conveying speed of the conveying mechanism 20 can be set according to actual needs, such as conveying at a constant speed all the time, accelerating conveying first and then conveying at a constant speed, or decelerating conveying and then conveying at a constant speed. In this embodiment, the conveying mechanism 20 conveys the substrate 21 in the form of a combination of rolls.

Referring to FIG. 4 , the spraying assembly 22 is used to spray the coloring liquid on at least one surface of the substrate 21 .

In this embodiment, since the spraying assemblies 22 are arranged on a beam 2201 according to the same first axis direction, the spraying distances between the nozzles 221 on the spraying assemblies 22 and the base material 21 are all the same. The spraying assemblies 22 are installed on the beam 2201 of the main frame body 220 at equal intervals, so that the spraying intervals of the spraying assemblies 22 are the same. The number of jetting assemblies 22 can be set according to the width of the substrate 21 .

By opening or closing valve 2211 at a particular pulse rate or frequency, the pulse rate or frequency is selected as a function of the desired amount of colorant fluid and the velocity of substrate 21 through jetting assembly 22 . The control device 23 is set to a pulse rate such that the valves 2211 on the nozzles 221 are opened or closed in a synchronized manner. In other embodiments, when flow control is not required, the colorant fluid may be injected in a continuous flow and not subject to pulses.
