Abstract

The invention discloses a full-process circulation dyeing system, which comprises a dyeing unit, a cleaning unit and a regeneration circulation unit; wherein the regeneration circulation unit comprises a dye capture separator, a salt concentration separator, a dyeing pool and a cleaning pool; based on the dyeing system, a textile is dyed by adopting a conventional dyeing process, and the wastewater in the dyeing process is captured and separated by the dye to obtain circulating water for dyeing, so that the circulating water is circularly used for next dyeing process; the wastewater in the processes of soaping, reduction cleaning, water washing and the like sequentially passes through a dye capture separator and a salt concentration separator respectively to obtain salt-free or low-salt-content colorless clear water, which is circularly used for next water washing process respectively. In the invention, all procedures are treated and circulated respectively from the source, so that themethod has the advantages of being simple, low in comprehensive cost, good in dyeing reproducibility, high in wastewater circulation rate, suitable for industrial application and the like.

Description

technical field

[0001] The present invention relates to the field of printing and dyeing energy-saving emission reduction technology and process technology, and more specifically relates to a full-process cycle dyeing system and its process and application. Background technique

[0002] The printing and dyeing industry is an important part of the textile industry. It is not only a key industry to improve product quality and increase product added value, but also an industry that consumes a lot of water, energy, and pollutants. In recent years, driven by the steady and rapid growth of the textile industry, printing and dyeing The industry has developed rapidly, but at the same time, it is increasingly restricted by resources and the environment. Energy conservation and emission reduction is an important measure to alleviate resource and environmental constraints, and an inevitable way to achieve sustainable development of the industry and transform the economic growth mode of...
