Zipper Tape: Zipper Tape (布带)
The woven or knitted fabric strip that carries the teeth and provides the sewing margin for garment attachment. Tape density, yarn quality, width and shrinkage control dimensional stability, seam appearance and pull strength. Polyester tape is standard because it resists washing and drying. Tape must be pre-stabilised so that the finished zipper does not shrink differently from the shell fabric and cause waviness at the seam.
