A combined anti-slip floor mat, including a mat body and a little mat, the mat body includes a leather, a PU self-skinning layer, and an anti-slip layer stacked together m that order. A recess is disposed in the middle of the top of the mat body, and the area of the recess is slightly less than the top area of the mat body; the little mat is matched to the recess in size. At least one opening is disposed on the middle of each side of the recess; wherein the opening passes through the floor mat; a cross notch is made on the bottom of the floor mat, by connecting each two opponent openings; the size of the little mat matches the recess on the mat body, and is separably embedded in the recess.

This invention provides an anti-slip floor mat with transparent top surface mainly includes a top surface, a PU self-skinning layer and an anti-slip layer stacked together in that order. The top surface is made of a transparent material. The PU self-skinning layer comprises foaming polyurethane and mainly formed by foaming an isocyanate with a polyether polyols intermixture, and the mass ratio of the isocyanate to the polyether polyols intermixture is 100:2050. A plurality of through holes passing through said anti-slip layer are defined in the anti-slip layer. A surface of said PU self-skinning layer adjacent to said anti-slip layer further comprises a plurality of rivets, said rivets pass through said through holes and extend to a surface of said anti-slip layer away from said PU self-skinning layer.

A layered composite includes an insulation sheet and at least one scrim layer secured thereto. The at least one scrim layer may be embedded within the thickness of the insulation sheet, or bonded to a corresponding face of the insulation sheet, and have a tensile strength greater than that of the insulation sheet. As such, the scrim layer provides structural support to the insulation sheet as well as a trap for fibers or particles that may separate from the insulation sheet.

Described are materials for a shoe upper, in particular for soccer shoes, with a particularly low weight. The material includes an inner polyurethane layer, an outer polyurethane layer, and a textile reinforcing layer. The textile reinforcing layer is arranged between the inner polyurethane layer and the outer polyurethane layer. The inner polyurethane layer and the outer polyurethane layer comprise thermoset polyurethane. The textile reinforcing layer comprises apertures through which the inner polyurethane layer and the outer polyurethane layer are connected to each other.
