To calculate this measurement, these devices work to remove the twist by mechanically rotating a yarn sample held between two moveable clamps with a defined tension rate. The number of rotations needed to untwist the yarn's fibers are then calculated. The higher the twist measurement, the stronger the yarn is determined to be. ]]></note></mads>
