S twist

noun

a direction of the twist in yarns, from top left to bottom right, resembling the long stroke of the letter S.

The average quantity of yarn turned off in a week of 69 hours is about 24 hanks per spindle of 30′s twist.

The spirals formed by twisting may extend upward to the left (the S-twist) or to the right (the Z-twist).

In one specimen (4-4056) the separate plies have an S twist, but the final yarn is untwisted.

Single-ply S-twist warps crossed by single-ply S-twist and Z-twist wefts (1 fine-texture specimen).
