Experiment Research on Effect of Moving Flat Speed on Carding Force in Carding Machine

In order to research the influence of moving flat speed on carding force between cylinder and flat, the carding force test was carried out under the condition of seven level speeds of the flat with a specially developed dynamometer. Experimental results show that the flat speed has an obvious effect on the carding force, which on the first to tenth flats have been more influenced. The carding force increases as the flat speed rises. When the flat speed is 650 mm/min, the carding force is the largest. Raising the flat speed is equivalent to reducing load on the flat clothing surface. Therefore, average carding force increase on single fiber explains the basic reason that incremental flat speed results in the carding force raising. Cotton fibre carding process has been basically completed between the 14th and 20th flats.
