Technical guide
S Twist and Z Twist in Yarn
S and Z identify yarn twist direction, helping buyers and production teams describe construction more clearly.
What yarn twist means
Twist describes the directional arrangement introduced into a yarn. S twist and Z twist are standard labels for that direction; the terminology supports precise communication, not a universal product recommendation.
Twist direction is considered with yarn construction, TPM, product category and intended application. A machine-specific recommendation is not assumed on this page.

Yarn Construction connects direction to the full yarn brief.
Application and sample review
When twist direction is relevant to an enquiry, include it with the intended application, construction information and any sample reference. The requirement can then be reviewed rather than inferred from a general rule.

Why does twist direction matter?
