DORNIER type EcoMerc® Tubular Mercerising Machine: a world beater:

The essential technical features of the circular expander system are as follows:
Reproducible values thanks to controlled tension throughout the treatment cycle.
With the fabric in its tubular state, optimum length and width control is
ensured for every diameter. Uniformity of stitches and wales throughout the
entire length and width of the fabric.

This ensures the avoidance of selvedge build-up and selvedge-tocentre shading
during dyeing.

Full mercerisation free from selvedge marks and stitch distortion.

Uniform fabric appearance, weights and shrinkage values as well as improved
dimensional stability and a permanent, high lustre. Technical details:

Circular expander with patented ratchet system. This means that various
spreading tension values can be applied with virtually constant traction force
while avoiding marks and stripes.

Drastically reduced set-up times thanks to powered adjustment of the circular
and flat tube expanders even while the machine is still running.

Crease-free fabric run thanks to ring expanders both in the impregnating and in
the washing sections.

Self-cleaning filters for lye and washing water.

25% higher washing capacity with the same low water consumption thanks to
counterflow system.

Lye cooling system and heat exchangers guarantee uniform, precise temperatures
in the impregnating and individual washing troughs.

Heat recovery system for the waste water.

Automatic control via PC of all variable machine parameters.

Visualisation of all processes and functions on colour monitor.

Prepared for the installation of a turntable and untwister at the fabric infeed.
