IMPACT OF TUBE WEIGHT ON RING FRAME POWER CONSUMPTION

In ring spinning mill 40% to 45 % energy is consumed by ring spin department alone, of which 70% to 80% energy is consumed by spindle motor. Saving energy has become an area of great importance in the textile industry as in every field. The aim of this study is to evaluate the impact of ring tube (yarn carrier) weight with respect to energy consumption in ring yarn manufacturing systems. This study also elaborates energy saving possibilities with respect to selection of yarn carriers. This study compared energy consumption with 3 different tube weight (40 g, 25 g and 17 g) with and without yarn formation keeping the same yarn content. Results indicated that the energy consumption (kWh) for bare tube running (without yarn) is 0.74% to 2.52% higher compared to the bare machine running without any tubes on the spindle. But the energy consumption difference increased from 2.85% to 5.2% when yarn produced. With the lower tube weight higher difference in energy consumption was observed. The slim tube (17 g and 25 g) produced by using lower density composites provided significant energy saving. Compared to 40 g standard tubes 25 g and 17 g tubes showing approx. INR 20 Lakhs and INR 36 Lakhs and above saving per year respectively for a 25536-spindle plant. This project study will help textile spinning industry leaders to choose slim tubes a better choice for optimising performance, minimising cost of yarn production per kg.
