Origin of Z twist
Examples from the Web for z twist
This sewing element, which serves as the weft, consists of 2-ply Z-twist cord with a medium-to-hard twist.
Cordage is of the 2-ply Z-twist type with each single S-twisted.
Single-ply S-twist warps crossed by single-ply S-twist and Z-twist wefts (1 fine-texture specimen).
The spirals formed by twisting may extend upward to the left (the S-twist) or to the right (the Z-twist).
The cord on these specimens is invariably of the common 2-ply Z-twist agave fiber.
