PET Non-Woven Geotextile
PET non-woven geotextile is a geotextile type made from polyester fibers using a non-woven manufacturing process. These geotextiles can be modified to enhance certain properties like resistance to ultraviolet degradation.
Composition and Structure
PET non-woven geotextiles are composed of polyester fibers made by mechanically bonding the fibers without weaving or knitting. The fibers in this geotextile are made from continuous filaments extruded in a long, continuous form devoid of breaks.
The result is a strong and stable material with a fabric-like interlocking structure. The fibers have a random fiber orientation that assigns isotropic properties to the geotextile.
Advantages
Some notable advantages of the PET non-woven geotextiles are captured below:
- They display considerable tensile strength useful in helping the geotextile withstand installation stresses and providing stability.
- Using this non-woven geotextile type improves load distribution and minimizes differential settlement enhancing overall soil stability.
- Their performance effectiveness over an extended life-time reduces need for frequent maintenance and thus overall cost needs.
- Their contribution to environmental protection is undeniable as they prevent soil erosion and promote effective drainage.
Application
Some of the applications of PET non-woven geotextiles are mentioned below:
Separation/Protective Barrier – In landfill engineering, waste containment, and environmental protection projects, these geotextiles are utilized in the separation of layers and as protective barriers.
Improve Soil Stability – Applications like embankments, mechanically stabilized earth walls and retaining walls use PET non-woven geotextiles for soil reinforcement. This improves soil stability by controlling soil movement and distributing loads.
Prevent Soil Erosion – Reservoirs and ponds utilize PET non-woven geotextiles as linings useful in containing water and preventing soil erosion.
Improve Filtration and Drainage – They are used in road and pavement construction to separate base material layers preventing intermixing which maintains structural integrity. Their use also enhances filtration and drainage reducing the potential for water damage.
