INVESTIGATION OF PARAMETERS OF NONWOVEN FILTER USED IN WHITE CELLS REMOVING

摘要

This paper is concerned with the relation between the parameters of nonwoven filter and removing of white cells. Melt-blown polypropylene nonwovens are used as filtration materials of white cells filter. According to the combination of different fiber diameter, different product density and different weight, optimized combination of parameters of nonwoven filter with more effective removing of white cells is obtained. The result is that removing of white cells is 96.90 percent; recovery of red cells is 92.27 percent.
