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

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.
