circular and sustainable textile industry.

Valérius 360 was founded in Portugal in 2017 The team from Valérius 360 wanted to find ways of
improving the processes for yarns made from 50 %
recycled and 50 % virgin cotton (Ne30). In particular,
it was seeking ways to reduce thick and thin spots,
which disturb the appearance of the textile surface.
At the Trützschler Technical Center in
Mönchengladbach, special trials were conducted
that showed that using a direct spinning process for
this application delivers much better results than a
process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly
