Polyester cleanroom fabrics were prepared by wet coating process using polyvinylidene fluoride. The effects of process conditions on the coated fabric properties were studied. It was found that the optimum process conditions were as fol-lows: PVDF mass fraction 14%, LiCI 3%, pre-evaporating time 30 s, the composition of coagulation bath NaCI: H_2O =5 :95,coating amounts 5 ～ 7 g/m~2. The particle filtration of the dustproof fabric was as high as 90%; the moisture and air permeabili-ty were excellent meanwhile.
