Spinning factory consumes the highest amount of electrical power compared to weaving, knitting, dyeing, and garment factories of the textile industry. A typical spinning unit of 20000 spindles requires about 2 megawatts (MW) of connected power to run the process machinery. Power is also a major cost component of yarn production after raw materials, and thereby the reduction of power cost is a paramount concern of the management of the spinning unit. This investigation aims to reduce power consumption of the ring frame using a plastic T-in cylinder. 2850 meters of 30 Ne yarn fineness was spun in a ring frame with a plastic T-in cylinder, and the same length of that yarn fineness was produced by the ring frame with a metallic T-in cylinder from the same feed material (roving). Power consumption was measured by a digital power meter during the production of the yarn at different set lengths. The power consumption was 39.5 kWh and 37.3 kWh, corresponding to metallic and plastic T-in cylinders. The reduced power consumption suggests that the setting up of a new spinning factory can be considered to be designed by ring frames with plastic T-in cylinders.
