The report describes laboratory and pilot scale testing of filter fabrics. Tests were made on flat specimens and on bags. Fifteen styles of fabrics (made from cotton, polyester, aramid, or glass) were tested, using cement, coal, or talc dusts. Collection efficiencies and pressure drop data are presented for inlet dust concentrations of 10-11g/cu m, filtration velocities of 60 and 80 cu m/sq m-hr, temperatures of 20-30C, and relative humidities of 55-60%. Conclusions reached were: (1) fabrics which performed well on bench scale apparatus also performed well on large scale apparatus; (2) free area calculations for characterizing fabrics are useful for staple fiber fabrics, but not for continuous filament fabrics; (3) smooth fiber fabrics with low coefficients of friction may have poor collection efficiency at high filtration velocities; and (4) cleaning properties of fabrics depend on the fabric composition and structure, and on dust properties, but not on filtration velocity. Collateral tests are described.
