2.1.1 SEFAR Fabrics Offering
2.1.1 SEFAR Fabric OfferingHumidity Influence on Polyamide fabrics
Polyamide absorbs up to
3.5 - 4.4% humidity
We can use this capacity
to achieve more tension
or compensation if the
humidity changes
Humidify the mesh either by:
1) Store the rolls or cut panels in a room or cupboard with
high humidity (+60%)
2) Leave the cut panel in a bucket of cold water for ½ an hour
-> Take it out and leave it hanging for ½ - 1h
Then continue to stretch the
mesh with the stretcher PN2

PET Grit Gauze
Hardly affected by humidity
Resistant to temperature changes
Keeps constant tension.
The rough fabric surface makes the
product remain longer on the sieve.
This leads to: better separation.

Vibro / Turbo sifters are used to sift the products
from the filters and bran finishers.
They are highly efficient, but they need frequent
controls.
