Needle-punched non-woven Geotextiles are made from polypropylene
fibres that are tangled together by a needle-punching process. The
fibres may be made in continuous or short lengths (the short length
fibres are called staple fibres) and achieve their strength by
interlocking. Needle-punched non-woven Geotextiles have excellent
water flow rates and are used for filtration of soil fines for
drainage applications including trench drains, as a wrapping for
perforated pipe, for erosion protection, and combined with
three-dimensional structures to create prefabricated drains. They
are also commonly used with geomembranes to provide a protective
cushion. Needle-punched non-woven primary functions: filtration;
separation; protection; drainage. Secondary functions:
reinforcement.
Performance
- PP Non Woven Geotextiles are designed in such a way to perform
the following 4 criteria
- Retention, Permeability, Clogging and Survivability
- Retention : This is a very important criteria. It prevents
excessive migration of soil
- Permeability : Permeable enough so that liquids are allowed to
flow without disturbing the flow rate
- Clogging : Enough pore openings to help filteration even if a few
pores are clogged
- Survivability: Must show strength, chemical resistance,
environmental resistance and maintain sustainability throughout the
usage life
Geotextile Functions :
- Separation function: Separation of two layers of soil with
different soil physical properties, such as road gravel from soft
sub-base materials.
- Filteration function: Retaining fine particles when water passes
from a fine-grained to a coarse grained layer, such as when water
flows from a sandy soil into a Geotextile wrapped gravel drain.
- Drainage function: To drain liquid or gas in the plane of the
fabric which results in draining or venting of the soil, such as a
gas vent layer in a landfill cap.
- Reinforcement function: Improving the load bearing capacity of a
soil structure, such as a high strength Geotextiles to reinforce a
retaining wall.
- Protection function: Mechanical protection of geomembranes
against perforation and abrasion, such as a liner protective layer
when only gravel fills are available.
