Saving water and energy with the
world’s leader in dyeing and finishing.
Wet finishing with air- the THEN-AIRFLOW ® technology reduces
the liquor ratio (an indication of the water consumption) by 50%
Water consumption in the textile production
To grow 1 kg of cotton, approximately 30.000 litres of water is needed. As we’re running
short on water, every measurement has to be taken to save this resource. Particularly in
sectors with a traditional high water consumption.
Focus on dyeing and finishing
For dyeing and finishing, about 150 litres water per kg of fabric are needed. Mainly the
impregnation of the fabric and the washing during the intersectional processes (like
scouring, bleaching and dyeing) are responsible for the usage of primarily fresh water in
the discontinuous applications. In the course of dyeing, the fabric is transported by a jet
nozzle, which is circulating the dyeing liquor. Afterwards the fabric is plaited for dwelling
in the dye bath as the second step of this cycle. This procedure is repeated constantly

until the dyeing is completed.
Water saving, best of class: THEN-AIRFLOW®
®
The patented THEN-AIRFLOW nozzle produces a mix of dye liquor and air, which
helps not only to achieve a better penetration of the fabric; it also reduces the necessary
water for this process by half. Consequently, the fabric does not need dwelling time in
the dye bath, like the traditional hydraulic systems. Above all that, less energy is needed
to heat up the water and the overall dyeing time will be reduced.
As far as the washing is concerned, “Direct” and “Power Rinse” together with the
opportunity to drain the water already at temperatures over 95°C also helps to save
energy and time. During the rinsing pre-heated water matching the exact requirements
of every single process is provided just in time to further shorten the cycle times and to
save energy.
Benefits

®
The best part of the THEN-AIRFLOW technology is the substantial reduction of the
liquor ratio. It comes together with savings in time and energy, too. The consequence is
a better effect- ecologically and economically. Reliable and reproducible.

The history of THEN-AIRFLOW®
Innovation starts with a simple thought. The thought of the R&D department of THEN
was related to the huge volumes of water used during the process of dyeing and
finishing. With the special design of the nozzle this volume now is created by an
aerosol- a mix of air and dye liquor. With this special application, the engineers of THEN
could reduce the volume of water for this process substantially.
