8. S is used to denote one of the two directions of twist (see quot.1935); so S-spun etc.

1935 Proc. Amer. Soc. Testing Materials 35 i. 448 A yard or cord has ‘S’ twist if, when held in a vertical position, the spirals conform in slope to the central portion of the letter ‘S’, and ‘Z’ twist if the spirals conform in slope to the central portion of the letter ‘Z’.

1950 A. V. Pringle Theory of Flax Spinning xiii. 45 Because the outer fibrils in flax ultimates are arranged in ‘S’ twist spirals it is considered that a stronger yarn or thread can be spun when the final twist is inserted ‘Z’-wise. Hence yarns for weaving are always spun Z-wise, but yarns for twisting are commonly spun S-wise.

1964 H. Hodges Artifacts ix. 129 Thus, if the threads are S-spun the ply will normally be Z-spun.
