A reinforced matting of melt-spun, interlooped, substantially amorphous and continuous synthetic thermoplastic filaments of which one set of filaments is applied with random penetration to a flat, latticed structure such as a fabric mesh or wire screen while another set of filaments may be added to form at least one and preferably several additional rows of interlooped filaments adhered to the first set of filaments carried by the latticed structure as a reinforcing member. This matting is made in a specific process requiring the first set of filaments to be melt spun at an angle inclined from the vertical onto the reinforcing member as a vertically conducted continuous band while the second set of filaments may be waterlaid on the surface of a liquid cooling medium, and the resulting filaments are then collected at or just below the liquid surface for adherent interlooping contact with each other and are carried on the reinforcing member through the bath as the filaments are completely solidified into a coherent self-bonded matting of high longitudinal and transverse strength.
