D2 – Advanced dyes and process chemicals

Partner: CHT, HN-FTB

Objective
The amount of water and energy consumed during conventional dyeing is tremendous. Reducing the water and energy consumption as well as the amount of chemicals released into our ecosystems are global challenges. The degree to which current generation can master these challenges will have a decisive influence on the well-being of future generations.

Current Results
In recent years, vigorous attempts have been made to save water and energy in textile finishing processes, especially by reducing the number and temperature of the rinsing baths.

This approach has been furthered consistently with the development of special auxiliaries like COTOBLANC SEL, SARABID MIP and VARIOBLEACH 3E and the BEZAKTIV GO dyes combined in the 4SUCCESS concept of system provider CHT Germany/Switzerland. These new dyes and the auxiliary technology enable a process with even lower temperatures during dyeing and rinsing. At the same time the process time is considerably decreased as fewer rinsing baths are required.

Expected Outcomes
Energy can be saved by reducing the number of required baths as well as lowering the temperature required for textile processing. By decreasing the amount of process water, waste water production is significantly reduced. Furthermore, the release of hazardous chemicals is lowered.
