ABSTRACT

According to the cost structure of the spinning mill given by Rieter, ring frame holds 60% share. As per the bifurcation of production costs in a spinning mill, 20% of the total falls under the heading “energy”. Out of total energy cost of spinning about two thirds are incurred only in the ring spinning section. The power consumption of ring frame is mainly utilized in drive given to drafting arrangement, spindles and builder mechanism. Hence the major share of about 65-70% energy utilized by ring frame is absorbed for driving spindles only. Thereby proper utilization of this larger energy share for getting

desired quality product at an economical rate becomes an utmost important. Technological problems associated with machine drive need to be resolved by identifying the variables influencing yarn tension during spinning.
