Abstract:

Polyelectrolytes such as poly(4-vinylpyridine) and poly(acrylic acid) with opposite charges have been deposited on a polyester fabric by the layer-by-layer technique. The first acidic layer with carboxylic groups were produced by grafting acrylic acid onto the polyester fabric according to the previously established grafting conditions. Selected fibre properties connected with the character of the deposited nanolayer of polyelectrolyte were tested. It has been found that the content of methylene blue dye in fibre and water retention depend on the character of the deposited nanolayer, as they are always considerably higher when the top nanolayer consists of poly(acrylic acid). Electron microscope photographs show that the fibre surface in the fabric becomes smoother after polyanion and polycation nanolayers are deposited.
