CA 2214771

The present invention concerns a composite for producing sports balls and shoe upper material from a multilayer composite, the outermost layer being an abrasionproof plastics layer which is connected to a second layer of a spun fibre non-woven fabric which has uniform expansion and resistance to tearing in all directions and is optionally connected to an innermost layer of a staple fibre non-woven material.

La présente invention concerne un matériau composite permettant de fabriquer des ballons de sport et un matériau destiné à la partie supérieure de chaussures. Ledit matériau composite est constitué de plusieurs couches, la couche extérieure étant une couche de plastique résistante à l'abrasion, reliée à une deuxième couche en non tissé de fibres discontinues, présentant un allongement et une résistance à la déchirure homogènes dans toutes les directions. Cette deuxième couche est le cas échéant reliée à une couche intérieure de matériau non tissé en fibres discontinues.
