Babar Shahbaz Assad Farooq Muhammad Asif 102003310The effect of beater speed, grid bar setting and cotton trash percentage upon Uniclean (B 11) and Giant cleaner setup were studied for quality characteristics of cotton. The results in respect of fibre length and uniformity ratio showed highly significant differences in the mean values for different combination of settings as well as cleaning segments. Uniclean exert swift gentle but firm action of less stress on fibres whereas the action of Giant cleaner is very aggressive and severe during its cleaning action, which is detrimental to fibre staple.]]>Anonymous,20002000Behery, H.M.,19921992Bel, P.D., C.L.
