Double-layer nylon tooth zipper

Abstract

The invention relates to a double-layer nylon tooth zipper. The double-layer nylon tooth zipper comprises a pair of first chain belts, a pair of first nylon teeth, a pair of second chain belts and a pair of second nylon teeth. Each of the first nylon teeth is provided with a first meshing end, and each of the second nylon teeth is provided with a second meshing end aligned with a corresponding first meshing end. A pair of fixing ends is arranged between the pair of second chain belts and the pair of first chain belts, and the pair of fixing ends makes the pair of second chain belts connected with the pair of first chain belts to gain a certain tension and prevent a sharp tool from squeezing downward and pushing apart the meshing joint of each first meshing end or the meshing joint of each second meshing end. No connection is arranged between from the pair of fixing ends to the pair of second chain belts and the pair of first chain belts sewn with the second nylon teeth and the first nylon teeth for the purpose of improving the moving space of a puller. By means of the pair of first chain belts and the pair of second chain belts, it is effectively prevented that a sharp tool pierces into the meshing joint of each second meshing end at the lower layer.
