Abstract
A face of a tennis racket includes a plain weave structure including a plurality of longitudinal threads, a plurality of high-tension transverse threads 36, and a plurality of low-tension transverse threads 38. The tennis racket includes a spin facilitating zone 46. The spin facilitating zone 46 includes: (1) a first high-tension transverse thread 36; (2) a second high-tension transverse thread 36; and (3) an odd number of low-tension transverse threads 38 positioned between the first high-tension transverse thread 36 and the second high-tension transverse thread 36. The spin facilitating zone includes no other high-tension transverse thread 36 positioned between the first high-tension transverse thread 36 and the second high-tension transverse thread 36.
