1. A tubular geotextile including implementing hydrophobic cellulose based threads, wherein the cellulose based threads include lyocell threads and the geotextile is knitted, and wherein the lyocell threads are at least one of i) comprising a fiber length between 10 mm to 40 mm, ii) comprising single ply within the range of 3-1 to 12-1, iii) comprising double ply within the range of 6-2 to 24-2, and iv) comprising triple ply within the range of 9-3 to 36-3, and v) treated to be hydrophobic, and are treated with food grade mineral oil.
