An instrument has been designed to measure the minimum twist of cohesion (MTC) of ring-spun yarn. The influence of spindle speed, traveller mass, and twist multiplier on the MTC has been studied using three-factor Box and Behnken factorial design. A very high coefficient of determination between the experimental values and the calculated values is obtained from the response-surface equation. The selected factors have significant contribution in determining the fibre cohesion in yarn. The optimum value of MTC is observed at higher level of spindle speed, traveller mass, and twist multiplier within the experimental zone explored. Spindle speed has the greatest influence on MTC, followed by twist multiplier and the traveller mass with the current experimental set-up.
