Abstract: This textile support is intended for the preparation of a tufted product such as an artificial grass or a carpet. It comprises at least one woven or non-woven lay. Technical yarns extend in one or two directions and are joined to the said lay for reinforcing it by knitting on a warp knitting machine, the said technical yams extending on the one hand in the warp direction and on the other in the weft direction on all or part of the width of the said lay.

Abstract: A composite geotextile or construction product for reinforcing a stratum of concrete or of bitumen comprises at least one reinforcing grid consisting of yarns which are mechanically strong in the warp and/or weft directions. It further comprises at least one layer of an openwork textile produced by weaving or knitting, the openwork textile having openings that are smaller than those of the meshes of the grid, the openwork textile being knitted with the grid by means of at least one knitting yarn, in order to obtain a substantial miscibility of the concrete or the bitumen in the composite textile product.
