Abstract:

A polyelectrolyte layer-by-layer technique for textiles has been examined. A nonwoven polypropylene fabric was grafted with acrylic acid, and films from poly(allylamine hydrochloride) PAH and poly(acrylic acid) PAA were deposited using the layer-by-layer procedure. It was found that the thickness of the deposited layers amounts to several nanometers, and the dyeing technique allows the type of external layer deposited to be identified.
