METHOD OF PRODUCING MATERIALS WITH ANTI-BACTERIAL PROPERTIES BASED ON COTTON FABRIC MODIFIED BY NANOPARTICLES OF ZINC OXIDE Russian patent published in 2017 - IPC D06M11/44 C01G9/02 A61L15/18 B82Y30/00 

FIELD: biotechnology.

SUBSTANCE: using the method of producing a material with anti-bacterial properties the cotton fabric is modified by nanoparticles of zinc oxide in the amount of 0.1-1.0 mg/cm² or -0.8-8% of weight. The modification is carried out by repeated wetting of the surface stretched to needle holders of cotton fabric dispersing zinc oxide nanoparticles in water or ethanol with a concentration of 0.1-0.6 g/l obtained by laser ablation. Wetting is followed by drying at a temperature of up to 100°C. The size of zinc oxide nanoparticles in a dispersion of 5-100 nm with an average value of 10-20 nm.

EFFECT: simple and inexpensive method of producing a material with anti-bacterial properties and with the specified content of zinc oxide particles on the surface.
