leading the world in the bonding of nonwovens.
Directed high-pressure water jets interweave the
manufacture of eco-friendly individual fibers together solely through the
momentum of the water. The material thus obtains a
high tensile strength and the desired textile feel

In Albaad’s WLS plant, Trützschler’s innovative
high-performance Streamliner dryer carries out the
bulk of the drying of the nonwoven material. The
spiral dryer section significantly increases the air
speed and thereby achieves optimal drying
performance. With the second drying step comes
another component of the system by Voith, the
contactless MCB drying system. Its uniform and
stable web run ensures the efficient residual drying
of the nonwoven material.

Moreover, Voith has equipped the WLM1 with a
comprehensive process and quality control system.
It monitors all the relevant parameters of production
and thus reliably ensures a high product quality.
