ABSTRACT: Pressure applied on the top roller of drafting zone is a vital factor on which the quality of ultimate yarn depends. Drafting zone is needed to reduce the mass per unit length of input material. Appropriate contact of top rollers with bottom rollers is necessary to ensure proper drafting. In this paper, the effects of different front top roller pressure of drafting zone on the quality of 20Ne cotton-flax blended yarns (C:L = 45:55) were studied. It was observed that a higher pressure value gives a lower co-efficient of mass variation, imperfections, hairiness and higher evenness, tenacity, elongation properties.
