Abstract
Theζ-potentials of anionic polystyrene latex particles and Nylon fiber were measured as a function of concentration of NaCl, Na2SO4, Na3PO4 and CaCl2, and the deposition of the latex onto Nylon fiber was considered. In the range of ionic strength from 5×10−4 to 5×10−2 where the rate of deposition was measured, the increase of electrolyte concentration resulted in the slight increase due to the adsorption of negative ion in the negativeζ-potentials of the latex particles. However, the rate of deposition increased with increasing concentration of electrolyte because of the decrease due to compression of the electrical double layer in the negativeζ-potentials of Nylon fiber. This result was supported by the fact that the maximum repulsive energy between electrical double layers of a latex particle and Nylon fiber decreased, as predicted theoretically, with decreasing ratio of theζ-potential of the fiber to that of the latex particle.
