Abstract: A zipper of the disclosure includes a pair of opposite tapes. A plurality of teeth are positioned at a bonding area of each tape. Each of the plurality of teeth 100 defines a positioning groove, and includes a post located in the positioning groove. A portion of the bonding area of the tape corresponding to each tooth defines at least one positioning hole. The post of each tooth passes through a corresponding positioning hole to fix the tooth on the tape firmly.

Abstract: A tape for derlin zipper comprises a plurality of warp yarns and a plurality of weft yarns interwoven with the warp yarns, the weft yarns are divided into a plurality of groups of weft yarns. The tape for derlin zipper includes two groups of clamping warp yarns, each group of clamping warp yarns includes a first clamping warp yarn and at least one second clamping warp yarn. The first clamping warp yarn and the second clamping warp yarn wriggle along a length of the tape to exchange positions with each other, and to form a plurality of clamping spaces. Each group of weft yarns passes through the clamping space with the first clamping warp yarns locate upon the group of weft yarns and the second clamping warp yarns locate under the group of weft yarns. A hollow area is formed between each two neighboring groups of weft yarns.
