Spunbond for Geotextile Applications
topic
Geotextile spunbond production uses heavy polypropylene or polyester spunbond at 80 to 500 grams per square metre with needle punch or through-air bonding reinforcing the thermally bonded web for the tensile strength and hydraulic conductivity requirements of separation, filtration, drainage, and erosion control geotextile applications, with UV stabiliser addition providing the outdoor durability needed for typical 25 to 50 year geotextile service life.
Role
Produces the dominant geotextile material type worldwide through spunbond continuous filament web formation that provides the combination of high tensile strength, controlled porosity for filtration, and UV stability for outdoor service that woven geotextiles cannot match at the production cost achievable by high-speed continuous filament spunbond processes for the high-volume civil engineering geotextile market segment.
