The cost of electrical energy to power spinning machines and looms accounts for 15 to 20 percent of textile production costs. Currently, this power costs between 2 and 2.5 Rs per unit. Power consumption depends on the following factors: speeds and weights of moving parts, machine condition, and operating paratices. Of the total mill power consumption, 75 percent occurs in the spinning department. Efficient use of power in the spinning department depends upon the selection of the proper motor, selection of the proper spindle, the use of nylon sandwich tape, replacement for the V-belt set when a belt breaks, selection of the proper cam for the building mechanism, reduction of the weight of the ring rail, selection of the proper tin drum pulley in the ring frame, the proper V-belt tension and pulley alignment, operation of machines at their optimum speed, and good maintenance. Of the total mill power consumption, 25 pecent occurs in the weaving department. Efficient use of power in the weaving department depends upon the releasing mechanism during picking, using a polymeric cam, selecting the proper loom for the type of yarn, selecting the proper motor, and maintaining proper belt tensions and pulley alignments.
