Spinning. Spinning is the single most costly step in converting cotton fibres to yarn. Currently, over 85% of the world's yarn is produced on ring-spinning frames, which are designed to draft the roving into the desired yarn size, or count, and to impart the desired amount of twist. The amount of twist is proportional to the strength of the yarn.
