  • Patent number: 5139859
    Abstract: The invention relates to a woven mat for humid spaces. The warp system comprises textile yarns (3a, 3b), which are preferably of a water-repellent synthetic material, and the weft system comprises at least an elastic, water-impermeable circular ribbon (1), such as a plastic or rubber circular ribbon. Thus water absorption is prevented in the mat, which does not feel wet. The mat is agreeable to stand on, owing to the elastic circular ribbon wefts, and the mat has an easy maintenance and dries rapidly. In addition to the circular ribbon wefts, the mat can comprise textile wefts, for example a ribbon and a textile yarn alternating in every second weft.The borders of the mat in the direction of the weft are bordered with a cleaved plastic hose (4), which is fixed by a listing seam (5) and on the borders in the direction of the warp simply a listing seam (5) is provided.
