The technology of applying a silver coating on fabric is presented. Tissue is wetted with a solution of copper sulphate, which is then reduced to metal-phosphide by phosphine treatment. Wetting can be carried out by immersing the fabric in a copper sulphate solution or spraying the solution onto the fabric using a sprayer. The subsequent processing step is the immersion of the fabric in a solution of silver nitrate, during this copper phosphide is transformed to a silver coating. The developed technology allows achieving a good grip of the fabric with a continuous silver films with a thickness from 40 to 600 nm. Using copper sulphate spray, coatings consisting of individual dots or clusters of silver were obtained. The silver coated tissues exhibited antimicrobial activity even after 10 washing.

Metallization of dielectrics a new physicochemical, mechanical and decorative properties is give to them 1-7. Depending on the type of dielectric material and on the aims to be coated, have been proposed various methods of metallization, among which was the largest use of chemical-electrolytic metallization 3,4. For create a conductive layer in this process the dielectric surface is activated by formation of a catalytic centers, which are then coated by chemical means. At that the active centers consisting of easily reduce metals atoms (copper, silver, palladium), through reduction of metal ions (adsorbed on the surface of dielectric material) by water-soluble or gaseous reducing agent are formed 1-7. As gaseous reducing agent most commonly used hydrogen, and the reduction reaction at high order of several hundred degrees temperature is carried out.
