The study reported in this paper concerns the influences of front top roll eccentricity in ring spinning machine), loading the top arm, pressure distribution on top arm through changing pin position and delivery speed on yarn irregularity and imperfections (thin, thick places and neps). The results show that: roll eccentricity has a positive effect on yarn irregularity and imperfections. This effect increases by increasing delivery speed. Loading the top arm of 2.3 bar with first pin position or 1.7 bar at third pin position reduced thin, thick places and neps at the higher delivery speed. Also pressure distribution (or pin position) influences yarn irregularity and imperfections at the higher delivery speed.
