发明名称 FLOOR MATTING/CARPETING
摘要 A mat/carpet (1) comprises an upper layer (3) having a soil-removing outer surface (7) for contacting traffic passing over the mat, and a lower layer (5) located below the upper layer. The upper layer comprises textile fibers (9, 11) and is water-permeable whereby water can drain from the upper layer (3) into the lower layer (5). The lower layer (5) is arranged to collect, for subsequent removal, water that is received from the upper layer (3), and may comprise channels (50) through which water can flow in a direction generally parallel to the soil-removing outer surface (7) of the mat.
