Mist spraying dyeing machine

Abstract

The invention discloses a mist spraying dyeing machine. The mist spraying dyeing machine comprises a U-shaped fabric storage tube and a dyeing tube which is horizontally arranged above the fabric storage tube, the two ends of the dyeing tube extend upward in an inclined mode relative to the horizontal direction and are communicated with the two ends of the U-shaped fabric storage tube respectively, and the communication positions between the two ends of the U-shaped fabric storage tube and the two ends of the dyeing tube are provided with a first rotating roller and a second rotating roller respectively, wherein the first rotating roller is used for driving a fabric out of the fabric storage tube to enter the dyeing tube, the second rotating roller is used for driving the fabric out of the dyeing tube to enter the fabric storage tube, and an aerosol spray head which vertically sprays dye liquor to the fabric is arranged on the upper portion of a horizontal section of the dyeing tube. By means of the mist spraying dyeing machine, the fabric is dyed more uniformly, meanwhile, the bath ratio is lowered, and dye liquor sewage is remarkably reduced.

Description

technical field [0001] The invention belongs to printing and dyeing equipment, in particular to a spray dyeing machine. Background technique [0002] There are generally two types of fabric dyeing techniques known in the industry, one is dip-dyeing and the other is spray-dyeing. [0003] In exhaust dyeing, a large amount of dyeing liquor is first placed in a large dyeing tank, and the cloth to be dyed is put into the large dyeing tank, and then the cloth to be dyed is dyed through dip dyeing. Although dip-dyeing can improve the washing fastness, since dip-dyeing is to put the whole piece of fabric to be dyed into a large dyeing tank, there will definitely be stacking of fabrics, and there will be problems of uneven dyeing. In the tank, all the fabrics to be dyed need to be submerged in it, and the amount of dyeing solution required is also large. When it is not used up, it is easy to cause waste, and the resulting discharge of sewage, waste gas and waste residue is also ser...

Problems solved by technology

Although dip-dyeing can improve the washing fastness, since dip-dyeing is to put the whole piece of fabric to be dyed into a large dyeing tank, there will definitely be stacking of fabrics, and there will be problems of uneven dyeing. In the tank, all the fabrics to be dyed need to be submerged in it, and the amount of dyeing solution required is also large. When it is not used up, it is easy to cause waste, and the resulting discharge of sewage, waste gas and waste residue is also serious, which is not conducive to environmental protection. Increase the production cost of the enterprise, leading to the decline of the competitiveness of the enterprise

[0004] Spray dyeing is to spray dye into the fabric to be dyed. Although it can solve the problem of dye waste, the effect of spray dyeing is not very good. There are poor washing fastness, different light fastness, and uneven spray dyeing, resulting in The dye cannot penetrate into the fibers of the inner layer, resulting in uneven dyeing
