Product Description
Product Introduction:
Using ultra-high-strength polypropylene staple fiber or ES fiber as
the main raw material, it is produced by non-woven technology and
has the functions of isolation, reinforcement, protection,
filtration, drainage, and buffering.
Product specifications: PP100~PP1200, width 2m~6m., length
according to user requirements.
Features:
The physical and mechanical properties are 2 to 3 times higher than
that of conventional products. The proportion of products with the
same gram weight is low; the acid and alkali resistance is
excellent, the hot melt adhesion is good, and the wear resistance
is strong. It is more suitable for CRTS/ slab ballastless track
sliding layer system, which can reduce the interaction between the
track system and the bridge surface.
Applications:
Polypropylene needle-punched non-woven geotextile is mainly used
for the sliding layer between CRTS slab ballastless track and beam
surface of passenger dedicated railway, and the isolation layer
between CRTS slab ballastless track and friction. It can also be
widely used Hydropower, highways, railways, ports, airports, sports
venues, tunnels, beaches, reclamation, environmental protection and
other fields play the role of isolation, filtration, drainage,
reinforcement, protection, etc.

Pro
Product Application
1. Road Work
Geotextiles are widely used in the construction of the road. It
reinforces the soil by adding tensile strength to it. It is used as
a rapid de-watering layer in the roadbed, the geotextiles need to
preserve its permeability without losing its separating functions.
2. Railway Works
The woven fabrics or the non-woven ones are used to separate the
soil from the sub-soil without impeding the groundwater circulation
where the ground is unstable. Enveloping individual layers with
fabric prevents the material from wandering off sideways due to
shocks and vibrations from running trains.
3. Agriculture
It is used for mud control. For the improvement of muddy paths and
trails those used by cattle or light traffic, nonwoven fabrics are
used and are folded by overlapping to include the pipe or a mass of
grit.
4. Drainage
The use of geotextiles to filter the soil and a more or less single
size granular material to transport water is increasingly seen as a
technically and commerc
