The invention relates to supporting fabric, made of practically rightangularly crossing, synthetic yarns and having a width of at least 30 cm, preferably more than 1 m, and a length of at least 3 m, for geotextile uses, such as for bearing one or more layers of sand, gravel, stones, clay, loam, asph
The invention relates to supporting fabric, made of practically rightangularly crossing, synthetic yarns and having a width of at least 30 cm, preferably more than 1 m, and a length of at least 3 m, for geotextile uses, such as for bearing one or more layers of sand, gravel, stones, clay, loam, asphalt, mortar or like bulk materials. The fabric has a tensile strength in one or more directions of at least 50 kN/m. The yarns of the fabric are in the form of tapes or threads, the material of the yarn chiefly being formed of polypropylene incorporating a polyester, and preferably polyethylene terephthalate. As determined by the total weight of the yarn, the polypropylene composes 75%-85% of the yarn, by weight, and the polyester composes 15%-25% of the yarn, by weight.

A supporting woven fabric, having a warp axis and a orthogonal weft axis, for stationary geotextile uses, such as for bearing one or more layers of sand, gravel, stones, clay, loam, asphalt, mortar or the like bulk or other material, to a height of at least 5-10 mm, the fabric having a tensile stren
A supporting woven fabric, having a warp axis and a orthogonal weft axis, for stationary geotextile uses, such as for bearing one or more layers of sand, gravel, stones, clay, loam, asphalt, mortar or the like bulk or other material, to a height of at least 5-10 mm, the fabric having a tensile strength along at least one of the warp axis or weft axis of at least 50 kN/m, comprises of synthetic yarns having a weight, the yarn being composed of polypropylene incorporating polyester, and the polypropylene is used in an amount of 75 to 85 percent by weight, and the polyester is used in an amount of 25 to 15% by weight, based on the total weight of the synthetic yarn.
