Monofilamentous string

Abstract

Monofilamentous string suited for use in tennis rackets and the like, consisting of a core material and a covering material that serves as a matrix, in which the core material is embedded in the covering material in accordance with the ‘island in the sea structure’ and that therefore contains island components and a sea component, therefore characterised in that the island components largely but not exclusively consist of a thermoplastic plastic, that they are arranged in a geometrical and preferably symmetrical pattern relative to each other and/or the longitudinal axis of the string, that at least three of these island components have a cross-section that has a multi-angular shape and with one side leaning close against the surface of the string, and that this side displays a curvature that closely lines the curve of this surface, and that the sea component largely but not exclusively consists of a thermoplastic elastomer.
