Title: COMPOSITION FOR IMPARTING ANTIMICROBIAL AND FUNGICIDAL PROPERTIES TO FIBROUS MATERIALS AND PROCESS FOR PREPARING SAME
Abstract:
A composition for imparting antimicrobial and fungicidal properties to a fibrous material by impregnation and thermal processing thereof, which composition comprises silver nanoparticles, polyvinyl pyrrolidone and water, characterized in that the composition additionally comprises a modifying additive, a nonionic surfactant and a рН regulator, with the following ratio of components in % by mass: silver nanoparticles 0.001 - 0.06; poly(1-ethenylpyrrolid-2-one) 0.01 - 0.6; modifying additive 0.5 - 3.5; nonionic surfactant 0.1 - 0.5; рН regulator 0.1-1.0; water - remainder. The application of said aqueous composition to fibrous materials imparts a wider spectrum of antimicrobial and fungicidal activity to said materials without the use of organic solvents.
