Power consumption in Spinning Mills
Since the unit price of energy and labor change independently from spinning mill conditions, reducing these costs depends on minimizing energy usage and labor wages. Since twisting is accomplished by the rotation of the spindle and bobbin, the energy consumption of ring spinning is higher than the other spinning systems.
