AI Technical Summary
Traditional waterproof zippers have insufficient waterproof performance at the meshing point, resulting in a low waterproof rating and limited use.
A nylon airtight zipper is designed by setting first and second waterproof layers on the zipper tape and providing first and second waterproof strips on the outside of the zipper teeth. The sealing is achieved by using the interlocking structure of the first protrusion and the groove, thereby enhancing the waterproof effect.
When the zipper is closed, the two waterproof strips adhere tightly to and cover the zipper teeth, and the protrusions are embedded in the grooves to cover the gaps, significantly improving the waterproof rating and enhancing the overall waterproof performance.
