摘要：
the object of the application is the way of dressing hydro\u017celowego with polymer matrix hydro\u017celow\u0105 containing poly (vinyl alcohol) (pva), which in the matrix hydro\u017celowej introduces active substances, characterized by that the matrix is prepared in hydro\u017celow\u0105 processin which: to an aqueous solution of silver nanoparticles with average particle size of 1 to 100 nm and a temperature from 80 to 90\u00b0c, in quantities to obtain the concentration of silver in the dressing hydro\u017celowym range 2,00 to 3.00 mg \/ kg (ppm) for all components of the dressing hy dro\u017celowego is pva in quantities of from 5 to 15% by weight.for all components of the dressing hydro\u017celowego and mixed solution by time from 9 to 12 hours producing aqueous silver nanoparticles in pva aqueous solution then decreases temperature silver nanoparticles in pva to temperature range from 68 to 72\u00b0c, after the aqueous solution of silver nanoparticles in pva is 14.2% solution in the solvent mixture of glycerine and eozyny forming water by weight ratio of 1: 5 in quantity to obtain concentration eozyny in dressing hydro\u017celowym in the range from 1 to 3% by weight.for all components of the dressing hydro\u017celowego and mixed composition obtained by time from 1 to 2 hours then decreases temperature obtained composition to temperature ranging from 62 to 67\u00b0c, after which the composition is to 24% solution in a solvent mixture which is allantoin propylene glycol and water, by weight, of 1: 3 in quantities to obtain the concentration of allantoin in dressing hydro\u017celowym range from 0.1 to 0.3% by weight.for all components of the dressing hydro\u017celowego and mixed composition by time from 1 to 2 hours then lowers the temperature of the temperature in the range from 58 to 62\u00b0c, then introduces the composition of preservative in quantities of from 0.5 to 1.0 wt%.for all components of the dressing hydro\u017celowego, stirring constantly compositi
