New dyes refer to innovations in textile dyeing technologies that aim to reduce the use of resources, toxic substances as well as the pollution and health hazards caused by current industrial dyes and processes. Examples include an advanced dyeing technology for cotton developed by the US company ColorZen® or EarthColors® by the Swiss company Archroma. The ColorZen® technology alters the structure of the cotton fiber on molecular level to increase the efficiency of the dyeing process. ColorZen® treatment prepares cotton fibers to accept dyes without the need for heavy chemicals, and has proven to significantly reduce water and energy use. EarthColors® are a commercially viable method of creating new dyestuff from natural non-edible by-products of the agricultural or herbal industries. EarthColor® dyes can be used for cellulose-based fibers such as cotton, lyocell, modal and viscose, and they are available in a range of shades. Achroma’s production cycle is traceable and transparent from the raw material to the final product in a closed-loop system, where it makes use of 100% of the raw material it acquires.(1-4)
