TFO (Two-for-One) Twisting Explained

27 July 2026 by

When a spec calls for two-fold yarn like 60s/2, it has usually been through a TFO. Here is what that means.

What TFO does

Two-for-One (TFO) twisting combines two single yarns into one plied yarn, inserting two turns of twist per spindle revolution — efficiently producing a balanced, two-fold yarn.

Why two-fold

Plying two singles (usually in the opposite twist direction) gives a yarn that is stronger, smoother and more even than a single of the same count — ideal for high-strength warps, fine shirting and sewing threads. See single vs double (TFO) yarn.

Specifying it

Quote the count with the fold, e.g. 60s/2. Convert and compare counts with the count converter. We supply single and two-fold yarn in cotton and blends.
