Waterproof and dustproof machine-sewn football and processing process thereof

Abstract

The invention discloses a waterproof and dustproof machine-sewn football and a processing process thereof. The football comprises ball skin and an inner container, wherein the ball skin comprises a plurality of ball skin pieces, the adjacent ball skin pieces are connected through sewing, the inner sides of the sewing joints of the ball skin pieces are coated with sealants, and gaskets are adheredto the inner surfaces of the ball skin pieces. The ball skin pieces are sewn through a machine, and the joints are coated with the sealants, so that primary waterproof and dustproof effects are achieved; after the inner container is inflated, the gaskets are extruded to be deformed so as to extrude and seal the joints of the ball skin pieces, so that secondary waterproof and dustproof effects areachieved; meanwhile, the machine-sewn joints are coated with the sealants, and the machine-sewing lines can be hidden on the inner sides of the joints through the extrusion of the gaskets at machine-sewn sites and cannot be observed from the appearance, so that the attractiveness is achieved; and the machine-sewn sites are sealed in two manners, so that the situation that dust and water enter thefootball is prevented, the waterproof and dustproof effects of the football are improved, and the service life of the football is greatly improved.

Description

technical field [0001] The invention relates to the technical field of soccer balls, in particular to a waterproof and dustproof machine-sewn soccer ball and its processing technology. Background technique [0002] 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 with 10 players and 1 goalkeeper, a total of 22 people, fighting, defending 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 shooting of penalty kicks (12 yards). In football matches, except that the goalkeeper can u...

Problems solved by technology

[0004] However, the dust-proof and waterproof effect of the existing machine-sewn soccer balls is not ideal. The sutures machine-sewn between the ball skins are squeezed and easily exposed to the outside of the ball skin after the inner tank is inflated. It will enter the inside of the football from the machine seam of the ball skin, affecting the use of the football, and the exposed machine stitching will affect the appearance of the football
