The price of football is the cheapest, and it is more expensive to sew by hand. As for gluing, it should refer to seamless thermal bonding technology, which should also be more expensive. In addition to price, their differences are also reflected in appearance and service life.
First, in terms of appearance,
1, the difference between hand sewing and machine sewing is not particularly big, but the naked eye can still easily tell the difference between them, and the machine sewing line is thinner and denser. But the hand-sewn lines are thicker and tighter. In the case of insufficient football inflation, the polygonal leather surface will bulge one by one.
2, seamless thermal bonding ball, as the name implies, the appearance is integrated, the seam is formed by thermal bonding, so there is no need to sew.
Second, in terms of use,
1, the machine-sewn ball is easy to bulge at the leather seam, so it is easy to wear in daily use, thus affecting the service life.
2. Hand-sewn football is hand-sewn, so the workmanship should be more detailed, and the quality is relatively better than machine-sewn football.
3. Hot-bonded football has no such worries.

Football (rugby)
Known as "the first sport in the world", it is the most influential single sport in the global sports world. In a standard football match, the two teams each sent 10 players and 1 0 goalkeepers, a total of 22 people, to fight, defend and attack on a rectangular grass court.
The purpose of the game is to shoot the football into the opponent's goal as much as possible, and you can get one point for each goal. When the game is over, the team with more points wins. If the score is the same within the specified time, it depends on the rules of the game. You can draw lots, play overtime or shoot each other. In the football match, except the goalkeeper can touch the ball with his hand in his own restricted area, each player can only control the football with other parts of his body except his hand (except the foul ball). ?
