For clarification of the deposition mechanism of dispersed particles onto textile fibers in sodium carboxymethylcellulose (Na-CMC) aqueous solution, the influence of Na-CMC on the deposition of polystyrene (PS) latex particles onto cotton and Nylon-6 fibers was studied from the standpoint of interaction energy between latex particles and fibers. Deposited amounts and the rate of deposition of PS latex particles onto cotton and Nylon-6 fibers in the presence of Na-CMC were less than when Na-CMC was absent. Elimination of the effect of Na-CMC for deposition may thus possibly be due primarily to electrostatic repulsive interactions, since total interaction energy (V<SUB>T</SUB>) due to electrostatic and van der Waals forces between latex particles and fibers increases greatly with the addition of Na-CMC. The addition of Na-CMC had virtually no effect on V<SUB>T</SUB> for Nylon-6 fiber, and thus possibly steric repulsive interactions due to Na-CMC adsorbed on Nylon-6 fiber may be essential to the deposition of PS latex particles.
