Abstract: Torsional properties of eighteen different commercial cotton hosiery yarns in the count range of 16s-40s Ne have been studied on a Torsiometer. The mean torsional rigidity, derived from the slopes of torque-twist hysteresis loop, relates very well with relevant fibre and yarn variables. It is observed that the increase in fibre span length and maturity leads to rise in mean torsional rigidity of cotton hosiery yarns while the finer fibres yield lower yarn rigidity. Moreover, the coarser yarns exhibit greater mean torsional rigidity while the yarns of higher tensile modulus show lower values.
