“Over the last 10 years, CO2 technologies have been proven to be a game changer in technology development and innovation within many industrial sectors, but particularly the textile industry.
The first chapter was written by FeyeCon together with its joint venture DyeCoo, which implemented a unique new supercritical dyeing process that saves 100 kg of water per 1 kg textile.
With its dry-dye technology for textile dyeing, DyeCoo uses no water in the process, as it has been replaced by high pressure CO2. Aside from eliminating the waste water, the use of CO2 reduces the amount of dyestuff needed. The dyestuff can also be recycled and reused in the process, which means that there is almost no waste whatsoever.
It is for these reasons that CO2-dyeing has gained its well-deserved reputation as a game changer for textile industries.
What is interesting is that CO2-dyeing is not a new process, and it took 20 years for its eventual scale-up and industrial implementation. This was the amount of time needed to fully appreciate the value of this technology. This time frame was not only necessary to understand the technical challenges, but to overcome the economic and market acceptance barriers associated with the novelty of the technology. Changes in the market and increased environmental awareness regarding the amount of waste water produced during conventional dyeing, made this technology a successful sustainable solution for better controlling the chemicals and resources used in textile dyeing.

Now, what would you say if FeyeCon states that it may only require a few more years to complete the next chapter and achieve a circular fashion economy by implementing CO2 technologies?
FeyeCon has already clear perspectives on the horizon on how innovative CO2 solutions can benefit woven and non-woven materials as well as fibers in the future. Such perspectives for the use of CO2 technologies include:
– Textile recycling (dyeing, discoloration and cleaning).
– Expanding the use of natural resources (upgrading the forestry and/or agricultural wastes or by-products) for creating sustainable fiber solutions.
– Textile finishing processes (coating, impregnating, surface modification etc.).
Such processes allow for the development of disruptive innovation textile concepts for new and expanding markets.
Implementing such recycled fibers in different fiber and textile concepts also allows the fiber industry to move from commodity towards an on-demand and a more flexible customer-oriented product development.
These are not only ideas but concrete concepts that are ready to be scaled up and implemented on an industrial level. However, these innovations can only be sustainable when supported by a new technical solution–and CO2 has already proven to be one of these sustainable solutions.”
