[0033] Embodiments of the present invention Figure 1 As shown in the embodiment 1, a stretch zipper includes at least two opposite chain cloth bodies 100 and chain teeth 200, the chain cloth body 100 includes at least one horizontally arranged weft unit 110 and a plurality of vertically arranged warp threads 120, the weft unit 110 includes elastic weft threads 111, the elastic weft threads 111 meander along the length direction of the warp threads 120 and are alternately woven with the top and bottom of the warp threads 120, the chain teeth 200 are arranged on the elastic weft threads 111, and further, the present invention gives the chain cloth a stretchable structure by the presence of the elastic weft threads 111. The excellent elasticity of the main body 100 enables the zipper to maintain the stability of its shape and structure when subjected to external forces, such as stretching or compression, and will not be damaged due to excessive deformation. The elastic characteristics of the elastic zipper allow users to open and close the zipper more easily, avoiding the zipper head sliding to a corner or a special shape due to the zipper cloth being too tight, which will limit the sliding of the zipper head, making it less smooth, or even causing the teeth to come off. The alternating weaving method of the elastic weft threads 111 and the warp threads 120 makes the structure of the chain cloth main body 100 tighter and stronger.

[0034] See also Figure 2In the second embodiment, the weft unit 110 includes at least one inelastic weft 112 arranged between the elastic weft 111 and the sprocket 200. The inelastic weft 112 meanders along the length direction of the warp 120 and is alternately woven with the top and bottom of the warp 120, while being alternately connected with the turning bend of the elastic weft 111 and the sprocket 200. Furthermore, by connecting the inelastic weft 112 with the sprocket 200 and the elastic weft, the presence of the elastic weft avoids the zipper head from being restricted from sliding when the zipper head slides to a corner or a special shape. The presence of the inelastic weft provides a more secure fixing point for the sprocket 200, which helps to reduce the risk of loosening or falling off of the sprocket 200 when subjected to force, thereby improving The reliability and service life of the zipper are improved, and the alignment between the sprockets 200 is ensured. In the present embodiment, the sprockets 200 can be connected to the inelastic weft thread 112 by sewing. In the present embodiment, the inelastic weft thread 112 alternately passes through a plurality of warp threads 120 and forms an inelastic left convolute 113 and an inelastic right convolute 114 on the left and right sides respectively. The inelastic left convolute 113 is interwoven and hooked with the inelastic right convolute 114, and the sprockets 200 are sewn into the inelastic right convolute 114, so that the elastic zipper can be more stable and durable. The sprockets 200 are sewn into the inelastic right convolute 114. This connection method makes the sprockets 200 more firmly fixed on the chain cloth body 100 to avoid tooth disengagement.

[0035] See also Figure 3 In the third embodiment, a non-elastic edge strip 300 is arranged between the elastic weft thread 111 and the chain tooth 200, one side of the non-elastic edge strip 300 is connected to the chain tooth 200, and the other side of the non-elastic edge strip 300 is connected to the elastic weft thread 111. Furthermore, the non-elastic edge strip 300 is also called a non-elastic edging strip, and the chain tooth 200 is embedded in the side of the non-elastic edge strip 300 away from the elastic weft thread 111. The elastic weft thread 111 and the non-elastic edge strip 300 are connected to each other by sewing. The non-elastic edge strip 300 provides additional support for the chain tooth 200, enhances the connection strength between the chain tooth 200 and the chain cloth body 100, and helps prevent the chain tooth 200 from loosening or falling off when subjected to force, thereby improving the overall stability of the zipper.

[0036] In the present invention, the elastic weft thread 111 includes a spandex thread and a double-strand polyester thread wrapped around the outer peripheral wall of the spandex thread.
