FIELD: textile.
SUBSTANCE: invention relates to the chemical engineering of fibrous materials and relates to a method for producing cellulose fibres impregnated with metal nanoparticles, particularly silver nanoparticles. Method comprises swelling cellulose fibres in an aqueous alkali solution. Swollen cellulose fibres are removed from the aqueous alkali solution and mixed with an aqueous solution of a silver salt and a polymer solution so as to impregnate the fibres with metal nanoparticles. Swollen cellulose fibres impregnated with metal nanoparticles are then removed from the solution. Invention further relates to the composition of cellulose fibres impregnated with metal nanoparticles and an absorbent material, in particular wound dressing, comprising a blend of cellulose fibres impregnated with metal nanoparticles with at least one other type of fibre.
EFFECT: invention enables to produce cellulose fibres for producing wound dressings having excellent antimicrobial properties.
