Coloring Fabrication of Self-assembly Multilayers on the Synthetic Fabrics with Polyelectrolyte and Various Dyes

Abstract

Recently developed electrostatic layer-by-layer deposition has been shown to be a simple and versatile method for assembling thin layer films. This technique provides a way to control the construction of ultrathin films at nano-scale ranges and can be easily obtained. However, there have been few studies on applying it to textile processing. In this context, alternate multilayer films of diazonium resin and coupling compound are prepared by self-assembly electrostatic attractions between oppositely charged ions. In addition to multilayer fabrication, the diazo coupling reaction proceeded at the same time to form nano-scale azo dye layer. The build up of the multilayer films has been discussed on the level of color strength (K/S) achieved. The growth of multi-layers formed by the sequential alternative adsorption and coupling reaction of diazonium resin and coupling compound was observed and determined.
