SINGLE LAYER NON-WOVEN FABRIC GEOTEXTILES WITH HIGH PERMEABILITY UNDER HIGH LOAD

摘要

The present invention, in the non-woven geotextile, forms a web of at least one of polypropylene fibers and polyester fibers having a thickness of 80 to 300 denier, the fibers of the web is randomly arranged with respect to the longitudinal direction of the web Carded to be stacked obliquely at a predetermined angle, and provides a single layer non-woven geotextile having a high transmission coefficient under high load pressure, characterized in that the web is needle-punched three-dimensional arrangement.
