A laminar material suitable for use in the manufacture of shoes comprising an extruded thermoplastic sheet core (10) having laminated thereto on at least one side a first fibre fabric layer (12), wherein the melting point of said first fibre layer (12) is similar to the melting point of the thermoplastic sheet core (10), and the thermoplastic sheet core (10) comprises: (1) recycled scrap laminar material comprising an extruded thermoplastic material having laminated thereto on at least one side a second fibre fabric layer, wherein the melting points of the extruded thermoplastic material and the second fibre fabric layer are similar to the melting point of the first fibre layer (12); or (2) virgin extrudable thermoplastic material having a melting point similar to the melting point of said first fibre layer (12); or (3) a mixture of both of these materials (1) and (2).
A laminar material suitable for use in the manufacture of shoes comprising an extruded thermoplastic sheet core having laminated thereto on at least one side a first fibre fabric layer, wherein the melting point of said first fibre layer is similar to the melting point of the thermoplastic sheet core, and the thermoplastic sheet core comprises:
A laminar material according to any one of the preceding claims wherein the thermoplastic material of the scrap laminar material has substantially the same melting point as the second fibre fabric layer.
A laminar material according to any one of the preceding claims wherein the melting point of the first fibre fabric layer has substantially the same melting point as the virgin extrudable thermoplastics material and/or the thermoplastic material of the scrap laminar material.
A laminar material according to any one of the preceding claims wherein the first and/or the second fibre fabric layer is a non-woven fabric.
A laminar material according to any one of the preceding claims wherein the first fibre fabric layer is constructed from the same material as the second fibre fabric layer and/or the thermoplastic material of the scrap laminar material and/or the virgin extrudable thermoplastic material.
A laminar material according to any one of the preceding claims wherein the first and second fibre fabric layer are each independently selected from polypropylene and polypropylene-polyethylene copolymer.
A laminar material according to any one of the preceding claims wherein the extrudable thermoplastic material is polypropylene.
A laminar material according to any one of the preceding claims having a fibre fabric layer laminated to both sides of the thermoplastic core.
A laminar material according to any one of the preceding claims wherein the recycled scrap laminar material is the same as the laminar material as defined in any one of the preceding claims.
A laminar material constructed arranged and adapted to operate substantially as hereinbefore described with reference to the accompanying drawings.
