CLASSIFICATION OF GEOTEXTILES
Previously to the classification we must clarify the meaning of some terms used frequently for geotextiles:
NON WOVEN
The fibers that make up the geotextile are placed randomly (Do not have two directions of fiber).
WOVEN
The fibers have two directions (warp and weft)
CONTINUOUS FIBER
Non woven geotextile fibers belonging to the final product are infinite.
CUT FIBER
Belonging to the finished fibers have a certain length.
NEEDLEPUNCH
The union between the fibers of the non woven geotextile is a mechanical bond by means of needles that go in and out at high speed.
CALENDERING
The union between the fibers of the non woven geotextile is a thermal bonding where the fibers pass through two calenders.
NEEDLEPUNCH + THERMOTREATED
The union between the fibers of the non woven geotextile is a mechanical bond by means of needles that go in and out at high speed, with a subsequent thermofusing creating the continous fiber in the final product.
