ABSTRACT The invention relates to supporting fabric, such as a woven fabric, a knitted fabric, a web or a deposition made up of prac- tically rightangularly crossing, substantially synthetic yarns and having a width of at least 30 cm, preferably more than 1 m, and a length of at least 3 m, more particularly for geotextile uses, such as for bearing one or more layers of sand, gravel, stones, clay, loam, asphalt, mortar or like bulk or other material, the fabric having a tensile strength in one or more directions of at least 50 kN/m. The yarns of the fabric are entirely or partly in the form of tapes or threads, the material of each of the tapes or threads chiefly being formed of a matrix of polypropylene incorporating a polyester, preferably poly- ethylene terephthalate. The matrix is used in an amount of 75 to 85 per cent by weight, based on the total weight of the tapes or threads, and the polyester is used in an amount of 25 to 15% by weight, based on the total weight of the tapes or threads.
