Clean dyeing (microcapsule dyeing) technology and equipment
With the clean dyeing technology, no additive is needed on dyeing and the waste water can be directly discharged or recycled. Therefore, it solves the problem of waste water treatment through the pollution root, and thus achieves non-polluting dyeing. It is a significant technology breakthrough to realize the clean production in the dyeing and finishing industry.
Fabrics don’t need to be rinsed after dyeing. This saves a lot of water and heat required by the traditional dyeing process.
Clean dyeing can be implemented on the traditional high temperature high pressure dyeing machine with only slight modification, i.e., the installation of a dye extraction machine. It is easy to master and apply.
Dyeing Quality Indexes such as levelness and color fastness are the same as or better than those of the traditional dyeing process.
