KNITTED GEOTEXTILE, AND GEOTEXTILE TUBE CONSTRUCTED THREOF

摘要

A geotextile for sediment dewatering and containment has a pattern of oriented warp fibers positioned substantially parallel to each other, a pattern of oriented weft inserted fibers positioned substantially parallel to each other and substantially perpendicular to the oriented warp fibers, a nonwoven fleece, and oriented knitting fibers that interconnect the warp fibers, the weft fibers, and the nonwoven fleece as a knitted structure. Because of the knitted configuration, the load bearing warp fibers and weft fibers remain substantially straight rather than interlaced asin a woven product. Consequently, the load bearing warp fibers and weft fibers take up stress immediately, thereby giving higher performance at lower strain. Because the load bearing warp fibers and weft fibers are substantially straight, they also retain their permeability under loading. Since more water flows through and from the geotextile, even when fully loaded, the dewatering process is both faster and safer to complete
