Staple Fiber Geotextile Lightweight and Easy to Transport and Lay
for Construction
Product Introduction
Short fiber geotechnical fabric mainly uses polyester fibers as raw
materials, and is produced through processes such as loosening,
combing, tangling, spreading, needling, etc., using non-woven
production equipment. This allows different fibers to interweave
and entangle with each other, forming a non-woven geotechnical
fabric with specific specifications.
Physical characteristics
Strength and elongation:Short fiber geotechnical fabric maintains sufficient strength and
elongation in both dry and wet conditions, with high tensile
strength and tear resistance.
Corrosion resistance:This material can withstand corrosion for a long time in soil and
water with different acidity and alkalinity, suitable for various
harsh environments.
Permeability:Due to the presence of gaps between fibers, short fiber
geotechnical fabric has good water permeability, which helps in the
discharge of moisture.
Lightweight:Short fiber geotechnical fabric is light and soft, making it easy
to transport, lay and construct.
Product Application
Staple fiber geotextile is widely used in many fields because of
its unique properties. It can be used as an isolation material to
deal with surfaces with complex terrain or large curvature. In
water conservancy projects, staple fiber geotextile can be used for
seawall, river embankment, river embankment, lake embankment
projects and reservoir reinforcement projects. In highway, railway
and airport engineering, it can be used in soft foundation
reinforcement treatment, slope protection, road remote reflection,
fracture structure bumble, drainage system and green isolation
belt. In addition, the staple fiber geotextile is also suitable for
environmental protection engineering, power plant engineering and
port waterway engineering and other fields.
