METHOD FOR PRODUCING A TEXTILE MATERIAL CONTAINING NANO- AND MICROENCAPSULATED BIOLOGICALLY ACTIVE SUBSTANCES WITH DELAYED RELEASE Russian patent published in 2021 - IPC D06M23/12 A61K9/10 A61K9/107 A61K36/06 B82B1/00 

FIELD: textiles.

SUBSTANCE: invention relates to a method for producing a textile material containing nano- and microencapsulated BAS with delayed release. In the proposed method, a textile material is treated with nano- and microemulsion containing nanocapsules and microcapsules with encapsulated biologically active substances included therein, followed by pressing and securing of the nano- and microcapsules on the surface of the material, final draining and drying. The nano- and microemulsion is prepared as follows: 100 ml of a 1% aqueous solution of polyelectrolyte I 10 g/l is added to 0.5 g of calcium carbonate, stirred for 20 minutes at 20°C, followed by centrifuging the solution at a rate of 2,000 to 4,000 rpm for 10 to 20 minutes, washing the resulting particles with water three times at a temperature of 20°C, adding 100 ml of a 1% aqueous solution of polyelectrolyte II 10 g/l, stirring for 20 minutes at 20°C, introducing a solution of a biologically active substance 5 to 15 g/l, adding the equivalent amount of ethanol and stirring for 20 minutes. Then the textile material if lowered into an impregnation bath with the prepared nano- and micro emulsion, sustained for 1 to 10 min, drained, impregnated with a solution of polyelectrolyte I 10 g/l, washed with water at a temperature of 20°C, drained, impregnated with a 1% solution of sodium polyelectrolyte II 10 g/l, washed with water at a temperature of 20°C, drained and dried at a temperature of 110 to 130°C. A preparation based on the strain of the Pleurotus ostreatus fungus RNCIM F-819 is used as a biologically active substance. Chitosan is used as polyelectrolyte I. Xanthan gum, guar gum, or sodium alginate are used as polyelectrolyte II.

EFFECT: enhanced therapeutic effect and increased duration of the effect on the skin of the patient in the affected areas when used for bedridden patients, as well as the maintained therapeutic effect even after 10 washes.
