Multi-layer substrates comprising top and bottom surface layers comprised of synthetic nonwoven fibers, and a melted thermoplastic material layer between the top and bottom layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100 F. to 350 F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the top and bottom surface layers that are in contact with the thermoplastic material as it melts.

Methods for forming multi-layer substrates comprising top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100 F.-350 F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may finally be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.

A decorative sheet includes a substrate and a surface protective layer formed on the substrate. A decorative plate is formed by laminating the decorative sheet on a base. The surface protective layer includes a first surface protective layer formed on the substrate and a second surface protective layer formed on part of the first surface protective layer. The first surface protective layer contains a curable resin and has a surface kinetic friction coefficient of 0.11 or more and 0.30 or less. The second surface protective layer contains at least one of resin beads and an inorganic compound filler. The first surface protective layer is glossier than the second surface protective layer.
