NON-WOVEN GEOTEXTILE WITH HIGH PERMEABILTY COEFFICIENT

摘要

This is designed weight per unit area is 1,000 ~ 2,000g / and 30 to 1,000 denier fibers horizontal stacking or pre- punched non-woven fabric and the inner fiber layer consisting of one ; Weight per unit area is 300 ~ 1,000g / and a 3 to 15 denier fiber is made with a pre- punched non-woven fabric , it characterized in that it comprises a pair of outer fiber layer bonded by needle punching on both sides of the inner fiber layer to provide a nonwoven geotextile with a high transmission factor .
