PET Nonwoven Geotextile
PET Nonwoven geotextile is non-woven needle punched geotextile, It is made of polyester or polypropylene fibers. It is a kind of insdustrial fabric.
Product Description
Description of PET Nonwoven Geotextile
1. PET Nonwoven Geotextile has good air and water permeability to let water flow through it so as to effectively control sandrock running-down.
2. Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
3. Geotextile helps to enhance the soil mass’ tensile strength and non-deformability and structural stability so as to improve soil mass quality.
4. It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
5. It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
6. Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
7. High water permeability-it can keep good water permeability even in the pressure of soil and water.
8. Corrosion resistant-it is made from polypropylene fiber or terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
9. Easy construction-low weight, easy operation, simple construction.

Application of PET Nonwoven Geotextile
Geotextiles are permeable nonwoven fabrics used to separate,filter,reinforce, protect or drain.Geotextiles allow filtration or separation of granular layers in roads and rail applications,used to protect membranes in landfill applications,used in coastal defence applications and used in landscaping to protect surfaces and structures from weeds and root growth.
Geotextiles are availabel as woven and non-woven .As liner protection, against physical damage, the non wovens are normally the answer.They are made up of fibers of polyester or polypropylene in random directions and punched together by needles during the manufacturing process.Geotextiles are commenly used to separate layers like clay and drainage and to protect liner from damage.
