Ball designs for sports games encompass a series of basic principles that support players. In general terms, lManufacturers seek to improve aerodynamics depending on the type of sport.
For example, the orientation of the seams in a Baseball ball, generates some changes in the trajectory when coming into contact with the air. The cracks of a Golf ball, decrease air resistance promoting longer and longer casts.
The design of paddle or tennis balls: Why are they rough?
When it comes to balls for padel or tennis games, the design focuses mainly on materials. The rough surfaces they are necessary to limit the speed, allowing the players to manage it. Otherwise, the balls would reach speeds too high to control, and easily cause wounds or injuries.
Why paddle balls are made with felt
Originally, tennis balls were made of flannel fabric, which offered good resistance and prevented speeds that were too high. Over time, the material was replaced by the felt nylon.
The aforementioned material is characterized by being a highly resistant synthetic fabric, this is especially true when it comes to abrasion. In this framework, the felt nylon extended the life time of these balls. Likewise, it has the necessary characteristics to oppose sufficient resistance, avoiding inadequate speeds.
Do you know what the fuzz effect of tennis balls is?
The fuzz effect is one of the attributes of felt nylon, it is the fluff that protrudes from the material, a product of wear. This fluff is capable of generating a drag force on the ball. In this way, it is possible to slow down a little the impulse of the ball into the air, controlling the speed.
The fuzz effect does not necessarily negatively affect the game
Although the fuzzy effect it is an indicator of attrition, it is not necessarily a factor that negatively affects the game. Taking into account that the balls with smooth surfaces are not suitable for playing paddle tennis or tennis, the fuzzy effect can be seen as something natural.
As for when to change the ball for wear, the main element is usually the level of pressure. In general, as long as it is not a question of competitions or tournaments, the balls are replaced by loss of pressure.
Ball Rescuer and the pressure of the balls
We remind you that the tennis balls or padel They start to lose pressure from the moment you take them out of their pot. Even after a day of practice they may have lost most of their internal pressure. However, this does not mean that you should replace them immediately. With the Ball Rescuer pressurizer, it is possible to restore its initial internal pressure several times.
