If เว็บแทงบอลออนไลน์ were used to inflate soccer balls the process would be more complicated and add an unnecessary expense to playing soccer. A good referee should check the soccer ball before each game to make sure it is suitable for playing a game. Weather and field conditions and the age of the soccer players may affect the referees judgement on the exact pressure she feels is best for all concerned. The standard soccer ball is made of synthetic leather, usually polyurethane or polyvinyl chloride, stitched around an inflated rubber or rubber-like bladder. Older balls were made of genuine leather and held shut with cotton laces. The synthetic leather panels are backed with cloth, usually polyester or a poly-cotton blend.
Under a barrage of negative publicity, reputable soccer ball manufacturers vowed to centralize their manufacturing under one roof, and not sub-contract to outside stitchers. Many of the largest manufacturers instituted human rights departments in order to guarantee that their balls were not being assembled by child or prison labor. Some athletes refused to endorse soccer products unless they had a guarantee that balls were produced under humane conditions. With high consumer awareness of the child labor problem, it is in the best interest of ball makers to monitor working conditions at their foreign plants. Some manufacturers are investing in technology that will eliminate hand stitching altogether. In the late 1990s, automatic stitching machines were able to produce low quality balls, suitable for non-professional play.

While early soccer balls were constructed in a number of ways, a fairly stadard 32-panel ball was designed by Danish national team goalkeeer Eigil Nielsen in 1962. This was followed by the introduction of the Adidas Telstar ball in 1970 based on a truncated icosahedron with white hexagons surrounding black pentagons.

I think any leather from 4-6 ounce would work (1.6mm-2.2mm). You don’t want to use leather from the stretchy portions of the hide like the belly as it can cause your panels to skew a little. The leather I used was a softer chrome tan leather similar to Horween’s Chromexcel.
The ball is also extremely durable, so you can enjoy playing with it for years to come. Working with our impact partners, PARK passes the donated ball to a kid or community in need. We support refugees, at-risk youth, abandoned children and girls, helping them play football.
