Dyeing system

Abstract

The invention relates to a dyeing system and belongs to printing and dyeing textile equipment. The dyeing system is composed of a dyeing machine, a vacuumizer and a distillation recovery device, wherein the vacuumizer and the distillation recovery device are arranged at the tail end of the dyeing machine, an air guide port is arranged on a channel cover of the dyeing machine and connected to an air inlet of the vacuumizer through a pipeline, an air outlet of the vacuumizer is connected to a distillation still of the distillation recovery device through the pipeline, a liquid discharge port is arranged on an organic solvent storage of the distillation recovery device and connected to a material feed pipe arranged on the dyeing machine through the pipeline, and an organic solvent circulating pump is arranged at the liquid discharge port. The dyeing system is reasonable in design, concise in structure, capable of meeting dyeing process requirements of dye liquid in which organic solvents and a little water are mutually soluble for objects to be dyed under a vacuum state and recycling the organic solvents, suitable for to-be-dyed objects made of different textile materials, safe, reliable and stable in dyeing processes, good in dyeing effect and environment-friendly.

Description

technical field [0001] The invention relates to a dyeing system, specifically a system for dyeing objects to be dyed in a vacuum state using organic solvent and a small amount of water-miscible dye liquor, which belongs to the category of textile printing and dyeing equipment. Background technique [0002] Traditional dyeing methods mostly use water as the carrier of the dye to dye the object to be dyed under normal pressure. However, on the one hand, the dyeing process not only needs to consume a large amount of water resources, but also a large amount of waste water seriously pollutes the environment and is difficult to recycle, which seriously restricts economic development. On the other hand, since the dyeing is carried out under normal pressure, it takes a long time for the gas adsorbed on the object to be dyed to be discharged after the dyeing solution is input and the dyeing starts. The air in the air often hinders the infiltration of the dye solution, so the dyeing ...

AI Technical Summary

Problems solved by technology

Although the vacuum process it uses can indeed improve the dyeing effect, its disadvantage is that the vacuum dyeing machine needs to use water as the carrier of the dye when dyeing the fabric, which consumes a lot of water resources and pollutes the environment. Moreover, the vacuum dyeing machine is not equipped with a recovery system, which cannot meet the recovery and recycling of dye liquor
