Arc zipper and manufacturing method thereof

Abstract

The invention discloses an arc zipper and a manufacturing method thereof. The manufacturing method of the arc zipper comprises the steps that straps are woven, wherein the outer arc cloth strap and the inner arc cloth strap are woven, and first high-temperature contraction lines are embedded into the tooth forming side of the inner arc cloth strap in the weaving process; teeth are formed, wherein the tooth injection molding is carried out on the tooth forming side of the outer arc cloth strap and the tooth forming side of the inner arc cloth strap, and the position between every two adjacent teeth on the inner arc cloth strap is provided with one high-temperature contraction line; the teeth are meshed, wherein the multiple teeth on the outer arc cloth strap and the multiple teeth on the inner arc cloth strap are meshed together; high-temperature contraction is carried out, wherein the outer arc cloth strap and the inner arc cloth strap with the meshed teeth are placed into a heating device to be heated to preset temperature, the preset period of time is kept, and each first high-temperature contraction line between the two corresponding teeth on the inner arc cloth strap contracts by the first length. The manufacturing method of the arc zipper can effectively solve the problem that stress of the teeth on the outer arc cloth strap of the arc zipper and the teeth on the inner arc cloth strap of the arc zipper is uneven.

Description

technical field [0001] The invention relates to the technical field of daily necessities, more specifically, to an arc-shaped zipper and a manufacturing method thereof. Background technique [0002] With the rapid development of clothing design, people have higher and higher requirements for every detail of clothing. In order to show personality, many clothes are designed with curved zippers. The curved zipper in the prior art includes an outer arc cloth belt and an inner arc cloth belt, and a plurality of teeth are arranged on one side of the outer arc cloth belt, and a plurality of teeth are arranged on one side of the inner arc cloth belt, The width of the teeth on the outer arc cloth belt is greater than the width of the teeth on the inner arc cloth belt, so that when the teeth on the outer arc cloth belt and the teeth on the inner arc cloth belt are engaged with each other, the zipper forms an arc-shaped zipper. However, since the width of the teeth on the outer arc c...
