DEPOSITION OF POLYSTYRENE LATEX ONTO FABRICS

In order to study the deposition of polystyrene latex onto the fabrics, viz, polyamide (Nylon 6), polyacrylonitrile (Vonnel), polyester (Tetoron), and cotton, ζ-potentials of latex and fabrics were measured, and heterocagulation theory was applied to explain the results obtained. The relation between the energy of interaction and the amount of latex deposited on the fabrics was investigated. The total interaction energy increased and the amount of latex deposited decreased with increasing pH for all the fabrics tested. In spite of the larger total interaction energy of Vonnel and cotton than that of Nylon and Tetoron, more amount of latex deposited on the above fabrics than that on the latter ones. From the observation of the state of deposition of latex particles in terms of scanning electron microscope, it was found that latex particles deposited on Nylon and Tetoron in a single particle layer, while those on Vonnel in a multiple or blocky layer. It is likely that the more amount of latex deposited on Vonnel than that on Nylon and Tetoron. © 1979, The Chemical Society of Japan. All rights reserved.
