Twist in yarns

This test determines the direction of twist in yarns, the amount of twist in turns per unit length and the change in length on untwisting by a direct counting method. The method cannot be used to yarns which stretch more than 0.5% when the tension increases from 0.5 cN to 1.0 cN or yarns with linear density over 2000 tex. Products with open-end spinning and interlaced multifilament yarns cannot be tested with this method.
