Problems solved by technology

[0003] The color water on the market has differences in color luster and poor color uniformity. It is easy to oxidize and fade when exposed to the air for a long time, so it is not suitable for washing gradient dyeing process
[0004] When the existing finished shoes and parts or materials such as TPU and acrylic (PMMA) are used as products, to achieve different color effects, we can only purchase fabrics or plates of different colors in large quantities, and the colors cannot achieve gradual and multi-color effects, resulting in a large number of The inventory pressure increases a lot of production costs for the production plant

Embodiment 1

[0029] The stain of the present embodiment, as a percentage by weight, comprises the following components:

[0030] RO pure water 98%, potassium aluminum sulfate decadecahydrate 0.1%, benzyl alcohol 0.9%, 50g / L na 2 SO 4 0.6%, pigment 0.4%. For the choice of pigments, they can be blended according to the needs.

[0031] Staining method of the stain of the present embodiment, comprising the following steps:

[0032] S1: Put the above stain into the staining cell and heat it up to 65 °C and keep it at a constant temperature;

[0033]S2: Step by step slowly sink and move the dye at a speed of 3mm gradient per second, the dyeing time is 60s, and when it reaches the set position, it automatically stops sinking and puts away the product to get the dyeing product. Because of the need to appear gradient color in the dyeing process, so the time to be immersed in the dyeing tank at different heights of the dyeing is not the same, according to the degree of dyeing, the dyeing to be contamin...

Embodiment 2

[0040] The stain of the present embodiment, as a percentage by weight, comprises the following components:

[0041] RO pure water 98.2%, sodium chloride 0.2%, benzyl alcohol 0.8%, 50g / L of Na 2 SO 4 0.5%, pigment 0.3%.

[0042] Staining method of the stain of the present embodiment, comprising the following steps:

[0043] S1: Put the above stain into the staining cell and heat it up to 70 °C and keep it at a constant temperature;

[0044] S2: Step by step slowly sink and move the dye at a gradient of 4 mm per second, the dyeing time is 75s, and when it reaches the set position, it automatically stops sinking and puts away the product to get the stained product.

[0045] S3: Automatically move the stained product to the ultrasonic cleaning cell for cleaning for 1.5 minutes, the power of the ultrasonic cleaning cell is 10kW, and the frequency is 20kHz.

[0046] S4: Dehydrate and dry the washed dyeing product.

[0047] S5: Put the dried dyeing product into the baking room or baking ...

Embodiment 3

[0050] The stain of the present embodiment, as a percentage by weight, comprises the following components:

[0051] RO pure water 98.4%, magnesium chloride 0.3%, benzyl alcohol 0.7%, 20g / L NaCl 0.4%, pigment 0.2%.

[0052] Staining method of the stain of the present embodiment, comprising the following steps:

[0053] S1: Put the above stain into the staining cell and heat it up to 75 °C and keep it at a constant temperature;

[0054] S2: Step by step slowly sink and move the dye at a speed of 5mm per second gradient, the dyeing time is 90s, and when it reaches the set position, it automatically stops sinking and puts away the product to get the dyeing product.

[0055] S3: Automatically move the stained product to the ultrasonic cleaning cell for cleaning for 2 minutes, the power of the ultrasonic cleaning cell is 10kW, and the frequency is 20kHz.

[0056] S4: Dehydrate and dry the washed dyeing product.

[0057] S5: Put the dried dyeing product into the baking room or baking lin...

Abstract

The invention discloses a dyeing agent and a dyeing method thereof. The coloring agent provided by the invention is prepared from the following components in percentage by weight: 98 to 98.4 percent of water, 0.1 to 0.3 percent of color fixing agent, 0.7 to 0.9 percent of benzyl alcohol, 0.4 to 0.6 percent of brightening agent and 0.2 to 0.4 percent of pigment. The coloring agent disclosed by the invention has the characteristics of uniform dyeing, good visual effect, high color stability and the like. The dyeing method of the dyeing agent comprises the following steps: heating any one of the dyeing agents in a dyeing pool, and keeping the temperature constant; gradually and slowly sinking the to-be-dyed object at the speed of 3-5mm gradient per second and inching, dyeing for 60-90s, automatically stopping sinking when the to-be-dyed object reaches a set position, and collecting the product to obtain a dyed product; sequentially carrying out ultrasonic cleaning, dewatering, spin-drying, drying and cooling on the dyed product to obtain a finished product. The dyeing method of the dyeing agent can dye gradient colors, and is more environment-friendly compared with traditional paint spraying.

Description

Technical field [0001] The present invention relates to the technical field of dyeing methods, in particular to a staining agent and a dyeing method thereof. Background [0002] At present, the water washing gradient dyeing process is a kind of color attached to the surface of the product object, it is dissolved by the water-soluble chromosomet solvent and the water-based potion (white, black, yellow) in order to play the role of color attachment, the chemical composition of the chromosome in the water-based environment, the water-based medicinal water (deionization, propanol dispersion, pigment) are water-soluble, the attachment of the surface color of the object, is achieved by the chemical reaction between the pigment in the chromosome and the water-based potion. [0003] There are differences in color gloss in the color water on the market, the uniformity of the color is poor, and it is easy to oxidize and fade after being exposed to the air for a long time, and it is not su...
