Abstract: Various ways of characterising the captured particle by filter fabric of different constructions are presented for plain, twill and satin cloth. With increase in filtration time, the volume and surface mean diameter decrease gradually for normal and below 53µ dust. With the increase in picks/cm for plain, twill and satin, the volume mean diameter and surface mean diameter show a reduction. Twill weave shows maximum volume and surface mean diameter followed by satin and plain of same cover at different durations of filtration. 90% volume percentile [D(V,0.9)] and 50% volume percentile [D(V,0.5)] decrease, whereas 10% volume percentile [D(V,0.1)] increases with the increase in picks/cm for all types of fabric. Plain fabric of same cover shows maximum value of [D(V,0.9)], [D(V,0.5)] and [D(V,0.1)]. During filtration of dust of particle size <53µ, decrease in [D(V,0.9)] and [D(V,0.5)] is less as compared to that in case of normal cement dust. The captured particle characteristics are influenced by unstable cake formation as confirmed by Malvern particle size analyser.
