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. ]]></termNote><termCreatedDate>2026-03-30 20:53:44</termCreatedDate><relation><relationType>UF</relationType><termId>31422138</termId><termName>twist tester</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31421990</termId><termName>fabric testers</termName><termType>PT</termType></relation></term>  </Zthes>
