[0036] Pretreatment: Before use, soak the metal powder in acetone solution for cleaning. Shake to wash more than 5 times, then filter and dry. Put in a desiccator for later use.
[0037] Implementation steps: fill metal powder such as metal titanium aluminum alloy powder into the dye crucible and fill it to a certain height. The fabric cloth is loaded on a cloth take-up and take-up system. Close the door of the vacuum chamber and turn on the vacuum pump to make the vacuum value lower than 5x10 -2 Then put an appropriate amount of oxygen and nitrogen into Pa, the ratio can be 1:9, or 9:1, or an intermediate value between 1:9 and 9:1, such as 1:6, the ratio depends on the needs of different colors, Different amounts of oxygen and nitrogen give color development from yellow to blue. Adjust the vacuum value to about 3x10 -1 P...

[0039] metallic color staining
[0040] Dyeing material: zirconium powder
[0041] Assistant gas: nitrogen
[0042] Cloth Material: Cloth of any material
[0043] Color: gold
[0044] Implementation steps: fill metal powder such as zirconium powder into the dye crucible and fill it to a certain height. The fabric cloth is loaded on a cloth take-up and take-up system. Close the door of the vacuum chamber and turn on the vacuum pump to make the vacuum value lower than 5x10 -2 Then put an appropriate amount of nitrogen into the Pa, and the amount of nitrogen filling depends on the needs of different colors. Adjust the vacuum value to about 3x10 -1 Pa. Turn on the power supply of the electron gun and adjust the current to 0.5A to 1A. Turn on the winding device, and the fabric starts continuous dyeing operation. When finished dyeing, release the vacuum chamber, open the door, and remove the fabric.
Embodiment 3
[0046] Dyeing material: disperse dye
[0047] Fabric: Polyester
[0048] color: red
[0049] Implementation steps: In this example, fill the disperse dye into the dye crucible to a certain height, and put the polyester into the winding device. Close the door of the vacuum chamber and turn on the vacuum pump to make the vacuum value lower than 5x10 -0 Pa, then turn on the power of the electric heater, adjust the current to 1A to 10A, the current depends on the evaporation rate and the depth of dyeing. Turn on the winding device, and the fabric starts continuous dyeing operation. When finished dyeing, release the vacuum chamber, open the door, and remove the fabric.

Abstract
The invention relates to a low-pressure dyeing device for cloths and dyeing method thereof. The device comprises: a sealed low-pressure chamber, a vacuum pumping device, a dye evaporating device and a winding device, wherein the vacuum pumping device is communicated with the low-pressure chamber and used for carrying out vacuum pumping on the low-pressure chamber; the dye evaporating device is placed in the low-pressure chamber; and the winding device is used for driving the cloths to move in the low-pressure chamber. The dyeing method of the low-pressure dyeing device for cloths comprises the steps of: carrying out vacuum pumping on a sealed box so as to form low pressure; filling in the dye evaporating device with dyes, wherein the dyes are heated by a heater and evaporated and the evaporated dyes enters into the sealed box through a dye inlet under the action of the low pressure; and driving the cloths to continuously pass through a position corresponding to the dye inlet. Anhydrous dyeing is realized through the device and the dyeing method; the device and the dyeing method are suitable for various synthetic fiber, natural fiber and blend fiber cloths; and the method can also be used for dyeing various cloths by utilizing inorganic dyes or organic dyes.
Description
technical field [0001] The patent of the present invention relates to the field of textile dyeing, and more specifically, relates to a low-pressure dyeing device for cloth and a dyeing method thereof. Background technique [0002] Most of the traditional fabric dyeing adopts wet dyeing process. For a long time, the wet dyeing process needs dyes and various auxiliaries. The dyeing process needs to consume a lot of water and energy, and the generated wastewater and discharge cause serious environmental pollution. . Although the dyeing and finishing industry has taken a lot of measures to save water and reduce emissions, none of them can fundamentally improve the problem of environmental pollution. Therefore, in the dyeing and finishing industry, the cost of chemicals and waste water treatment is extremely high. In order to reduce the pollution problems mentioned, there is an urgent need to establish a water-free dyeing process. [0003] In the prior art, there are two anhyd...
