A term that applies to the number of turns and the direction that two yarns are turned during the manufacturing process. The yarn twist brings the fibers close together and makes them compact. It helps the fibers adhere to one another, increasing yarn strength. The direction and amount of yarn twist helps determine appearance, performance, durability of both yarns and the subsequent fabric or textile product. Single yarns may be twisted to the right (S twist) or to the left (Z twist). Generally, woolen and worsted yarns are S-twist, while cotton and flax yarns are typically Z-twist. Twist is generally expressed as turns per inch (tpi), turns per meter (tpm), or turns per centimeter (tpc).

The number of turns about its axis per unit of length of a yarn or other textile strand.

The winding of yarn around itself. More twist improves carpet performance, especially in a cut pile carpet.
