The most popular sport practiced worldwide is football. Everyone has, more or less, played it at some point or another, whether they are young people living in the richest countries or those growing up on the streets of a third-world country. Despite this, the majority of regular people are unaware of how footballs are made or the materials that are employed.
In this article, we examine the materials used in football production as well as the manufacturing method.
Over time, footballs have evolved in terms of size, shape, and appearance. Today’s footballs are produced after months of research on designing and material selections to maximize their efficacy on the game, as “The Beautiful Game” incorporates more and more technology. Large centers for research and development have been established by companies like sportswear tycoons Adidas, Nike, Puma, and others in order to continually improve and produce results to match the changing demands of the game.
A lovely history
Since the time of their original production, footballs have advanced significantly. In those days, the finished product was made by wrapping inflated pig bladders in leather. Compared to the balls we see or play with now, they used to be tied up with laces and were much heavier. Modern-day balls were first produced using the patented vulcanized rubber developed by self-taught chemist and manufacturing engineer Charles Goodyear. The spherical shape is produced by manufacturers using leather patches that have hexagonal and pentagonal shapes.
The term “buckyball” refers to the most popular type of ball in use today. It was given to honor renowned architect Richard Buckminster Fuller, but its official shape name is “spherical polyhedron.”
The characteristics of modern football
Modern footballs contain a lot of geometrical elements. A total of 32 panels, made up of 20 hexagons and 12 pentagons, are used to create the ball’s necessary spherical shape. These panels are firmly sewn together and made of leather or synthetic plastic.
International regulations specify the proportions of the ball. It should have a spherical shape, measure between 27 and 28 inches, weigh between 0.39 and 0.44 kilograms and be filled to a pressure of 6.8 kilograms per square centimeter.
To enhance the overall durability and a better playing experience for the user, the ball also contains numerous layers constructed of various materials. Since no material has been used to make a football that is flawless, each football created of a particular material has its own combination of benefits and drawbacks. Each of them also has disadvantages, which we are exploring more in this post.
The topmost layer
The synthetic outer covering improves water resistance and adds to its attractiveness while reducing wear and tear by shielding it from scuffs and scratches. Football of the highest caliber uses polyurethane because it provides the ball with the best feel.
Although PVC increases durability, it also reduces the ball’s feel and the enjoyment of the game as a whole. Additionally, PVC hardens the outside covers, making them unsuitable for use as playthings. Footballs are given a felt outer covering for use in indoor games because felt improves ball control on smooth surfaces and is also used to coat tennis balls.
Inside lining
Between the outer layer and the inner bladder, there is an inner lining. The substance in this layer affects how springy the ball is. The footballs used in premier leagues and other elite sports have many inner lining layers.
This layer is made of materials like cotton and polyester. Cotton provides the necessary softness, while polyester offers the ball the necessary responsiveness and durability. Cheaper footballs are tougher and more difficult to manage since they include less cotton and more polyester, but they are still strong.
The Bladder
The bladder, which keeps the air inside the ball, is its most crucial component. The most used bladder material is butyl because it is strong and effectively retains the air. One disadvantage of employing butyl as the bladder material is that it quickly deforms when kicked, which reduces its responsiveness.
Professional football players choose latex over butyl because it is more responsive. The disadvantages of butyl are that it is less durable and loses air more rapidly. To lessen bouncing, indoor football balls’ bladders are filled with foam rather than air.
Stitching
The stitching comes next. The panels of the ball are held together by this, therefore it needs to be done very carefully. Due to its durability and lack of absorption, polyester is the most widely used material for stitching. Kevlar, which offers improved durability and water resistance, is another material employed.
The Adidas Jabulani ball from the 2010 World Cup was manufactured by thermally gluing the panels together, which made it smoother than typical balls because there were no seams, but it also garnered harsh criticism from many players and coaches due to its unpredictable behavior in the air.
The valve
The valve is the area of the ball through which air is blown to inflate it. It is a needle-like structure that, from the outside, appears to be a tiny hole. They are often constructed of rubber or butyl. When the air pump needle is placed into the ball, it opens without difficulty. Its elastic nature causes it to close fast when the pump is taken out. Since silicone valves retain air better, they are also widely used.
There is little potential for invention by the makers because the shape, size, and weight of the ball are governed by international regulations.
To improve gaming, manufacturers are working to make the ball softer while keeping it sturdy. Additionally, they are working to advance sewing technology so that all types of balls can be stitched by machines, minimizing the need for human labor.
Football is commonly made of FAQs
1) What animal is a football often made of?
Despite the fact that the ball is not constructed from pig skin, players and spectators have been calling it a “pigskin” for decades. Why? These days, cowhide is used to make footballs.
2) Where are most footballs produced?
Footballs are made by numerous businesses all around the world. Wherever the game was played, local manufacturers produced the first balls. In addition to China and India, Sialkot, Pakistan, is thought to generate 40% of the world’s footballs.
3) What kind of material is ideal for football?
Artificial leather
The greatest footballs are typically made with synthetic leather, giving players the best feel and control. The majority of training balls are made of tough, quality PU material, however, some less expensive ones still use PVC.
4) What material does a football have?
Spheroid Prolate Shape
A football, on the other hand, has a prolate spheroid form with a polar axis that is larger than its equatorial diameter and owes its two-dimensional genesis to the ellipse rather than the circle. A football will spiral when thrown properly due to its lengthy shape.
