Geosynthetic Fabric Flat Yarn PP Woven Geotextile Use Prevent Grass Grow
Flat Yarn PP Woven Geotextile Description
PP Woven Geotextile Made from PP ( polypropylene ) or PE flat yarn on circle weave machine .The Flat strip woven geotextile, high tenacity woven geotextile made of Polypropylene and polythene flat strip as raw material, by two sets of parallel yarn (Its shape is flat wire), a set of longitudinal yarn along the loop warp marching direction, another set of horizontal layout called weft. Using different weaving equipment and processes interweave together woven cloth, according to the different using range woven into different thickness compactness. The woven geotextile has quite a strong tensile strength , has good stability, low elongation and light weight.
Flat Yarn PP Woven Geotextile Function
1. Reinforcement: used in highway, railwau, airport, dam, breakwater slope, retaining wall backfill soil, slope rock engineering, dispersive soil stress, increase soil modulus and limit soil slip, improve stability.
2. Protection: prevent the bank from wind, weave, tide and rain erosion, and used for bank protection, slope protection, bottom protection, prevent water loss and soil erosion.
3. Filtration: used in filter layer of dam, dyke, the river and coastal rocks, slope, retaining wall, prevent sand grains through, and allow the water or free air to pass through.
Flat Yarn PP Woven Geotextile Property
1. Light weight , high strength , low elongation , easy to construct
2. Separation , Reinforcment , Draginage , Filtration , Protection , Fencing function and so on .
Flat Yarn PP Woven Geotextile Application
