Description
技术领域technical field
本发明涉及体育器材制作技术领域，尤其涉及一种足球材料及制作工艺。The invention relates to the technical field of sports equipment production, in particular to a football material and a production process.
背景技术Background technique
足球，有“世界第一运动”的美誉，是全球体育界最具影响力的单项体育运动。标准的足球比赛由两队各派10名球员与1名守门员，共11人，在长方形的草地球场上对抗、进攻。比赛目的是尽量将足球射入对方的球门内，每射入一球就可以得到一分，当比赛完毕后，得分最多的一队则胜出。如果在比赛规定时间内得分相同，则须看比赛章则而定，可以抽签、加时再赛或互射点球等形式比赛分高下。足球比赛中除了守门员可以在己方禁区内利用手部接触足球外，球场上每名球员只可以利用手以外的身体其他部分控制足球（开界外球例外）。现有技术中，足球大多不够耐磨，而且大多采用真皮皮革制作，不环保，因此，需要一种新材料诞生。Football, known as "the world's number one sport", is the most influential individual sport in the global sports world. A standard football match consists of two teams consisting of 10 players and 1 goalkeeper, a total of 11 people, fighting and attacking on a rectangular grass field. The purpose of the game is to shoot the football into the opponent's goal as much as possible. Every time a ball is scored, one point can be scored. When the game is over, the team with the most points wins. If the score is the same within the specified time of the game, it depends on the rules of the game, and the game can be divided in the form of drawing lots, overtime rematch or mutual penalty kicks. In football matches, except that the goalkeeper can use his hands to touch the football in his own penalty area, each player on the field can only use other parts of his body other than his hands to control the football (except for throw-ins). In the prior art, footballs are mostly not wear-resistant enough, and most of them are made of real leather, which is not environmentally friendly. Therefore, a new material needs to be born.
