Capillary imbibitions were of practical importance in many industrial processes such as textile, ceramic, and pharmaceutical industries. In earlier studies, it had been found that the resistivity of terylene or polypropylene fabrics decreased via water penetration, but little work has been done on imbibitions process which is essential to reveal the interrelation between water penetration and conductivity of terylene or polypropylene fabrics. The study was inspired by the requirement to investigate more details about these interrelations. The results showed that drop spreading existed in imbibitions experiments when the hydrophobic fabrics were contacted with water. Five different physical stages occurred successively during the imbibitions behavior experiments, namely solid-liquid contact(A), imbibition(B), steady balance(C), solid-liquid separation(D) and evaporation of external liquids(E) stages. The phase of solid-liquid contact reflects the equilibrium relationship between the wetting tension and the buoyancy of the liquid. The resistivity of polypropylene fibrous decreased to 2.4×105Ω•cm when WHC was 0.01Lm-2, thus would be enough to meet a demand or requirement for collectors. The discharge current by polypropylene collection electrode was 5~20 percent higher than that by FRP. The spontaneous immersion for water into hydrophobic fabric collectors would be of practical importance for the purpose of uniform water film distribution via capillary flow, thus would allow lower water addition rate and non-interrupted operation for industrial use.
