the influence of raw material quality and processing factors on the incidence of yarn faults has been studied by using the uster classimat system. factors like the quality of raw material, degree of opening and cleaning in the blowroom, type of carding and amount of waste removed during combing significantly influenced the number of faults in spun yarns. tandem or double carding at low production rates and combing are the surest ways of reducing the incidence of yarn faults. the use of overhead cleaners during spinning reduced the fault level appreciably. increase in spinning draft and spindle speeds increased the number of faults due to the irregularities and end breaks produced during spinning. the setting of the cradle opening during spinning is of extreme importance not only in terms of irregularity, but also in terms of the number of disturbing faults in yarn. 5 refs
