Needle-punched non-woven geotextile

Home Geotextile Nonwoven Geotextile Needle-punched non-woven geotextile

Categories: Geotextile, Nonwoven Geotextile
  • Description

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
