Torsion can be a valuable measurement to evaluate cuticle integrity and damage to the hair. The cuticle layers of the fibre contribute more to the fibre torsional stiffness than tensile and bending deformations, making this a valuable assessment if you wish to study cuticle damage.

Our FTT950 systems allows torsion force, torsion/shear modulus (with dimensional data), torsion stress relaxation and other parameters to be calculated, as well as being fully automated for a high throughput and efficient workflow.
