The work presented in this paper is related to using textile materials as fabric filter bags for fly ash retention from a power station. An experimental study has been performed on the effects of antistatic liquid treatment on the deposition of fresh fly ash onto fibres. It was observed that a thin crust of very fine particles was deposited on the treated fibres and that this crust was not influenced by the material from which the fibres were made. In contrast, on untreated fibres, medium and large particles, distinctly deposited, were seen instead. The adhesion of the encrusted fine particles on the treated fibres was so strong that the particles could not be dislodged by removal accelerations as high as 105 g. In contrast, the larger particles which adhered to the untreated fibres were dislodged at much lower accelerations. The possible causes of the observed deposition and adhesion behaviour due to antistatic treatment are discussed.
