Abstract |
The report identifies a semi-empirical relationship for fabric air filters between clean cloth fabric structural parameters, dust parameters, and filtration performance. High outlet concentration caused by bleeding or seepage of dust is a function of the pore size distribution of the fabric vs. size properties of the dust. A significant number of pores with a characteristic dimension roughly 10 times the mass mean particle diameter of the dust being filtered leads to bleeding and seepage of dust. This conclusion results from studies with three dusts (fly ash, limestone, and silica), a number of fiber types, and a range of fabric construction variables. Pressure-related filtration performance can be correlated with clean fabric free area if yarn boundaries are well defined. Since many yarn boundaries are not well defined, clean cloth Frazier permeability may be used as an alternative method of correlating pressure-related filtration performance. (Author) |
