Abstract (en)

[origin: WO2011039482A1] This core (2) for a racket string, in particular for a tennis racket string, comprises a thermoplastic matrix (24) in which filaments (22) are embedded, at least one of these filaments being of natural origin and the thermoplastic matrix (24) being made of a material which, at a temperature lower than a threshold temperature, at which the filaments (22) are not substantially damaged, has a viscosity making it suitable for an extrusion process. The matrix (24) comprises a plurality of strands that are helically twisted in a first direction, each of the strands comprising a plurality of filaments (22) of natural origin that are helically twisted in a second direction, which is or is not opposite to the first direction.
