00The behaviors which are shown by a textile material when it is subjected to a torsional force is called torsional property. 1.    Torsional rigidity 2.    Breaking twist 3.    Shear modulus 1.Torsional rigidity: Torsional rigidity can be defined as the torque required against twisting is done for which torque is termed as torsional rigidity. Mathematically, torsional …
