MAIN FEATURES

The non-woven geotextile is one of the fabrics, and as the name implies these products are characterized by technical and not aesthetic parameters, such as for textiles from clothing or furniture. The main parameters to consider are the following, generally in order of importance:

MECHANICAL CHARACTERISTCS

tensile strength (value in kN / m "kilo Newton meter) and relative elongation rate
reference standard UNI EN ISO 10319

Static puncture (N value in "Newton")
reference standard UNI EN ISO 12236

Dynamic indentation (value expressed in mm)
reference standard UNI EN ISO 13433

HYDRAULIC CHARACTERISTICS

permeability perpendicular to the plane (value in m ^ 3 / m ^ 2s "cubic meters of water per square meter per second)
reference standard UNI EN ISO 11058

opening size (value expressed in um Micron)
reference standard UNI EN ISO 12956

Other features to be considered by designers and project managers depending on the specificjob.
