The small yellow ball is often covered with small hairs which are not really, the explanations.
Are you a big tennis fan, do you never miss Roland-Garros or do you handle the racket just like that from time to time, for fun, with friends on Sundays? Whatever your affinity with this sport, you have certainly already noticed a few hairs on your little yellow ball. In addition to feeling a strange sensation in your hands, know that it is not actually “hair”. the small yellow ball is actually covered with a rough surface, the “felt”. This surface is made up of nylon or wool fibers that are woven onto the ball, improving its characteristics for playing tennis.
The felt of the tennis ball is simply essential to provide grip, especially for professional players (but also amateurs) who play with a lot of effects such as the slice (effect given to the ball when hitting it laterally from top to bottom). This extra grip from the felt fibers allows the ball to grip the court surface and bounce more predictably, providing a more dynamic and therefore more enjoyable game for spectators and/or viewers.
This layer that covers the ball also protects the core of the ball, which is usually made of rubber, providing additional protection of durability and resistance. It is also for this reason that all the players take the time to choose the balls, they evaluate the quality of the latter. If damaged, spin or bounce will not be the same as a new ball.
