Abstract

See full text

A racquet string includes a core component whose principal component is a synthetic fiber, and a surface resin component, wherein fullerenes or by-product carbon particles derived from manufacture of fullerenes are blended into the surface resin component, and wherein the blended percentage content is in a range of at least 0.01 wt % and at most 5.0 wt % of the entire string. The surface resin component may be formed as a sheath component by coating or by composite spinning. It is preferable that the amount of fullerenes or by-product carbon particles derived from the manufacture of fullerenes that is included in the surface resin component is in a range of at least 0.1 wt % and at most 25 wt %. Thus, the durability of the racquet string is improved without substantially changing its physical properties.
