Abstract
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 (VT) 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 VT 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.
