Layer-by-layer self-assembly deposition of polyelectrolytes on textile materials might provide a new approach to endue different functions to textiles. Two simple characterization methods for electrostatic self-assembly deposition of two typical polyelectrolytes, poly(sodium 4-styrenesulfonate) (PSS) and poly(diallyldimethylammonium chloride) (PDDA) on cotton fabrics were investigated in this paper. Dyeing of the PSS/PDDA assembled cotton fabrics with anionic Direct Red 80 and cationic Methylene Blue shows regular and observable "odd-even" oscillations in terms of color depth (K/S value), which could be utilized for the assessment of the variation of surface electric property of the cotton substrate due to the alternate fabrication of PSS and PDDA on it. A linear increase in UV absorbance at 226 and 261 nm of treated cotton fabrics further revealed that the growth of these layer-by-layer multilayers could be recorded by monitoring UV spectra of assembled cotton specimens. ATR FT-IR spectra did not show any identifiable differences between cotton substrates with and without deposition of PSS/PDDA multilayers.
