The term "Nonwoven
Fabrics" was created in the United States to designate the whole group of
textiles produced by unconventional method.
i.e. mechanically bound and chemically bonded nonwoven fabrics may be
considered, from the viewpoint of their structure, as fibrous systems reinforced
with either of the two existing binding or bonding systems.
used for producing NON-WOVEN GEOTEXTILES are exclusively the synthetic fibers.
The non-woven will have the best properties as optimum conformity can be
achieved with wide choice of production methods, fiber type, fineness and staple

mechanical and chemical bonding.
ensures high tensile strength and high extensibility in the meantime. Reasonable
mechanical bonding gives the required tensile strength while chemical bonding
integrates the same effect and leads to high extensibility. Also, chemical
bonding produces a fabric of higher resistance to mechanical abrasion due to
creation of heat and thus more adhesive forces.
Moreover a fully isotropic can be produced with
nonwovens which have enormous advantage over woven fabrics. They separate the
parent soil from the drainage media. They are also used in other civil
applications such as drainage, reinforcement between soil to soil to stone or
aggregate and asphalt to asphalt in road and railway works, erosion control and
The three major sub-divisions of non-woven GEOTEXTILES based upon the way in
which the non-woven GEOTEXTILE fibers are bonded together are : Thermally
Bonded, Chemically bonded and Mechanically Bonded, or combination of the last
