Tape for Derlin Zipper

摘要

A tape of the disclosure includes a plurality of warp yarns and a plurality of weft yarns interwoven with the warp yarns, the weft yarns divided into a plurality of groups of weft yarns. The tape includes two groups of clamping warp yarns each including a first clamping warp yarn and a 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 weft yarns passes through the clamping space with the first clamping warp yarn located upon the group of weft yarns and the second clamping warp yarn located under the group of weft yarns. A hollow area is formed between each two neighboring groups of weft yarns.
