Dyeing method of cloth and dyeing machine

Abstract

The invention discloses a dyeing method of cloth, namely, dyeing the cloth by utilizing the atomized dye in a static electric field; the invention further discloses a dyeing machine which is used for dyeing the cloth and the dyeing machine comprises a rack, a cloth rolling delivery system and a dyeing system, wherein, the cloth rolling delivery system delivers the cloth to pass through the dyeingsystem; the dyeing system is an anion static electricity dyeing system which comprises a dye jar, a dye delivery mechanism and a dye atomization dyeing mechanism; wherein, the dye atomization dyeing mechanism is composed of the atomized elements and a static electricity generator; the anode and the cathode of the static electricity constitute the static electricity field; the atomized elements are close to the cathode of the static electricity generator; the dye jar is connected with the atomized elements of the dye atomization dyeing mechanism through a dye delivery mechanism; the cloth delivered by the cloth rolling delivery system attaches to the anode of the static electricity generator and passes through the static electricity field. The invention can dramatically improve the uniformity and color yield rate of the cloth dyeing, reduces production cost substantially and reduces the great pressure brought about on the environment.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing, in particular to a cloth dyeing method and dyeing equipment. Background technique [0002] At present, most of the cloth dyeing in the prior art adopts the padding method, that is, the cloth roll is sent to the dipping tank equipped with dye solution, and the cloth is dipped in the dipping tank under the open width, and then the excess dyeing solution is dried by rollers and then dipped. color. This method belongs to the passive dyeing method, that is, the cloth is immersed in the dye solution, and the dye molecules freely penetrate into the cloth fibers and then complex with the fibers. The dyeing mechanism is: reactive dyes are complex dyes and have anionic molecular bonds, while the fabric fibers after boiling and bleaching have cationic molecular bonds. The cloth is immersed in the dipping tank containing the dye solution, the dye freely penetrates into the cloth fiber, and the anionic...

Problems solved by technology

Therefore, there are often color differences between different pieces of the same batch of cloth, and even the color of the cloth head and cloth tail of the same cloth is also different.

[0005] 3. In the process of exhaust dyeing, since the dye molecules are freely infiltrated and complexed to the fabric fibers, the complexation arrangement is not neat, and the complexation ratio of the dye is low (only 60% to 70%), and many complexes are poor. The dye molecules become floating colors, which not only wastes the dyes, but also consumes a lot of water and energy in the subsequent washing process to clean the floating colors, resulting in a large amount of printing and dyeing sewage, which is not only not conducive to environmental protection, but also increases production costs. and sewage treatment costs

[0006] 4. It needs to consume a large amount of soda ash, salt or sodium bicarbonate as color fixation and accelerator, which not only increases the production cost, but also produces a lot of waste, which puts a lot of pressure on the environment
