The report describes pilot scale and laboratory tests of U.S. and Polish woven baghouse fabrics. Cotton, polyester, aramid, and glass fabrics were tested using cement, flyash, coal, and talc dusts at loadings of about 10 g/cu m, filtration velocities of 60 and 80 cu m/sq m, and ambient temperature and humidity. General conclusions reached were: (1) air permeability is a poor predictor of fabric performance, (2) fabric construction parameters do not correlate well with the resistance coefficient for fabrics Kl, (3) a critical value of pressure drop exists above which fissures are formed in the dust cake, (4) there is a maximum in the efficiency versus air-to-cloth-ratio curve which is related to fissure formation, and (5) cleaning properties of the fabric depend primarily on its chemical composition, the dust being filtered, and the superficial structure of the dust cake and fabric (they do not depend on air-to-cloth ratio).
