Monofilamentous string

Monofilament racquet string, comprising a core material and a covering material that serves as a matrix in which the core material is embedded in the form of an ‘island in the sea structure’ and accordingly contains island components and a sea component, wherein the island components largely comprise a non-elastomeric thermoplastic polymer and are arranged in a geometrical pattern relative to each other and/or the longitudinal axis of the string, and at least three of said island components have a cross-section that has a multi-angular shape, with one side adjoining a surface of the string and wherein said at least one side has a curvature that closely follows the curvature of the string surface, and the other islands are circular or oval in form and are disposed in alternating relationship with the multi-angular shaped components circumferentially of the longitudinal axis in the sea and wherein the sea component largely comprises a thermoplastic elastomer.
