Manual Verses Electronic Spindle Ring Alignment and its effect on Ring and Compact Yarn Properties

For studying the effect of spindle ring alignment that is eccentricity of spindle, the spindles are set at different eccentric gauges. Starting from perfectly centred at the gauge of0 to the gauges of 3 and 6away from the centre, with the help of electronic spindle centring gauge. The effect of these eccentricities on the properties of ring and compact yarn of different counts have been observed. Similarly the comparative study between the manually centred spindle set by using mechanical gauge and spindle centred by using electronic gauge have been carried out.The unevenness (U%), imperfection index (IPI)are significantly affected by ring eccentricity and no effect on to the hairiness and CSP value of ring yarn. In case of compact yarn there in no effect of ring eccentricity on to the hairiness, U% and IPI of yarn. The results also state that the manual ring centring by skilled technician is similar to electronic ring centring
