Abstract

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.

Claims

exact text as granted — not AI-modified
1 - 14 . (canceled) 
     
     
         15 . Carpet comprising an upper layer having a soil-removing outer surface for contacting traffic passing over the carpet, and a coextensive lower layer located below the upper layer and secured thereto, the upper layer comprising textile fibers;
 wherein the upper layer is water-permeable whereby water can drain from the upper layer into the lower layer; and the lower layer is arranged to collect, for subsequent removal, water that is received from the upper layer.   
     
     
         16 . Carpet as defined in  claim 15 , in which the upper layer comprises a textile pile layer that provides the soil-removing outer surface. 
     
     
         17 . Carpet as defined in  claim 16 , in which the pile comprises at least one of cut pile fibers and loop pile fibers. 
     
     
         18 . Carpet as defined in  claim 17 , in which the pile layer is a tufted layer. 
     
     
         19 . Carpet as defined in  claim 17 , in which the pile layer has a backing that comprises an impervious material, the backing being perforated to permit the passage of water therethrough. 
     
     
         20 . Carpet as defined in  claim 15 , in which the lower layer comprises channels through which water can flow in a direction generally parallel to the soil-removing outer surface of the carpet. 
     
     
         21 . Carpet as defined in  claim 20 , in which the channels are defined by extruded polymeric material. 
     
     
         22 . Carpet as defined in  claim 20 , in which the channels are provided by a layer of non-woven material or coiled web material. 
     
     
         23 . Carpet as defined in  claim 15 , including a base layer located below the lower layer for containing water that is collected by the lower layer. 
     
     
         24 . Carpet as defined in  claim 23 , in which the base layer is water impermeable. 
     
     
         25 . Carpet as defined in  claim 15 , in which the lower layer has a water-impermeable lower surface for containing water that is collected by the lower layer. 
     
     
         26 . Carpet as defined in  claim 25 , comprising an edging at the periphery of the carpet for containing water that is collected by the lower layer. 
     
     
         27 . Carpet as defined in  claim 15 , the carpet being located in a recess in a floor for containing water that is collected by the lower layer. 
     
     
         28 . Carpet as defined in  claim 15 , in which the upper layer is removably-secured to the lower layer.
