Description
Introduction:
Dongkai Needle-punched nonwoven geotextiles are made from polypropylene fibres that are tangled together in a needle-punching process. The fibres may be made in continuous or short lengths and achieve their strength by interlocking. Needle-punched nonwoven geotextiles have excellent water flow rates and are used for filtration of soil fines.
Features:
- A continuous felt mat of polypropylene fibers
- Consistent filtration properties
- Consistent water flow properties
- Provides light-weight, low cost protection for geomembranes
Applications:
- Prevent the loss of soil fines when wrapped around drains
- Allows high water flow rates
- Heavier fabrics can provide drainage in plane
- Used as a protective cushion for geomembranes
