What is Geotextile?
Needle-punched PET filament geotextile is a specific type of geotextile made from polyester (PET) filaments through a needle-punching process. In this manufacturing technique, continuous PET filaments are mechanically entangled with one another using barbed needles, forming a non-woven fabric structure.
Here are some key characteristics and features of needle-punched PET filament geotextiles:
1.Non-Woven Structure: Unlike woven geotextiles, needle-punched geotextiles have a non-woven structure, which means the filaments are not interlaced in a traditional weaving pattern but rather entangled through mechanical processes.
2.High Strength: Despite being non-woven, needle-punched PET filament geotextiles offer high tensile strength and puncture resistance, making them suitable for applications requiring reinforcement and stabilization of soil.
3.Permeability: Needle-punched geotextiles maintain permeability, allowing water to pass through while providing effective filtration to prevent soil erosion and clogging of drainage systems.
4.Dimensional Stability: These geotextiles exhibit good dimensional stability, maintaining their shape and structure under various environmental conditions.
5.Chemical Resistance: PET filaments provide resistance to chemical degradation, enhancing the durability and longevity of the geotextile in harsh environments.
6.Versatility: Needle-punched PET filament geotextiles find applications in a wide range of civil engineering projects, including road construction, embankment stabilization, erosion control, landscaping, and drainage systems.

Production Process & Package
DXD is dedicated to an objective of continuous commitment to quality. This dedication begins with the manufacture of the geosynthetic material and ends only when our customer has accepted our products. The employees of DXD, therefore, endorse and require a policy of Total Quality. This policy is based on the principle that quality is the fundamental responsibility of every department and is carried out by each person in that department.
Programs and procedures designed to implement this quality principle are developed by the Quality Control Department and are utilized by every employee of the Company. DXD Manufacturing processes are ISO 9001:2015 registered.
..................................
Geotechnical Engineering:
Geotextiles are applied in various geotechnical engineering projects, including embankment construction, soil reinforcement, foundation stabilization, and ground improvement techniques such as soil nailing and geotextile tubes.
Agriculture:
Geotextiles are utilized in agriculture for soil stabilization, weed control, and moisture management. They are used in landscaping, horticulture, and geotextile bags for erosion control, drainage, and protection of crops and soil.
Vegetated Reinforcement:
Geotextiles are combined with vegetation in applications such as green roofs, vegetated slopes, and erosion control blankets. They provide structural support for plant growth, enhance soil stability, and promote ecological restoration in urban and natural environments.
Landfills:
Geotextiles are employed in landfill engineering to line waste containment cells, provide drainage and filtration layers, and prevent soil erosion and contamination of groundwater.
Erosion Control:
Geotextiles are used in erosion control applications such as slope stabilization, shoreline protection, and riverbank reinforcement. They help prevent soil erosion caused by water and wind, thereby protecting vulnerable landscapes and infrastructure.
