The relationship was studied between the quality of. the sliver and the acting angle of the metallic wire using by a carding machine equipped with a doffer wound by wire fillet card clothing. The acting angle of the doffer on this experiment was 40°. The acting angle of the metallic wire was changed from 75° to 60° and its point density was 356/ (25.4mm) 2. Also, the angle of the flat was changed from 75° to 95° to study the corelation between the angle of the cylinder and the flat. The results were as follows : 1) By lowering the angle of the metallic wire from 75° to 65°, the amount of the nep in the sliver was decreased. However, at 60° in the acting angle of the metallic wire, the neps were much more decreased than at 65° under the angle of the flat of 95°. 2) The neps in the sliver was decreased in propotion with the increase of the flat angle. 3) The trush in the sliver was unchanged with the change of the angle of th metallic wire. But, it increased by increasing the flat angle. 4) The mean length of the fiber in the sliver was not affected by the angle of the metallic wire. The same results summarized above will be obtained even if the fiber transfer ratio of the doffer wound by the metallic wire is same.
