Introduction
Dressing made of materials that have both protective, antimicrobial and sorption properties are most effective in the treatment of postoperative wounds in surgical practice. The developed dressing material consists of fiber components of various chemical nature with one of the layers being treated with antimicrobial drugs [1].

Optimal ratios of raw components and structural parameters of multilayer nonwoven materials were developed based on the results of the research of the kinetics of sorption and desorption of liquid environments imitating exudate, as well as the diffusion of antimicrobial drugs from one structural component of the material to others and into the surrounding space [2]. It was established that the main impact on the absorbing ability of a multilayer nonwoven material is made by the raw material composition of the inner layer. To a lesser degree - the thickness of the material, its surface density and the number of layers [3-6].

There are two stages of the treatment of postoperative wounds, in particular, in oral and maxillofacial surgery: the first (1-5 day) with intensive exudate secretion and the second one (6-9 day) - with moderate exudate secretion. Based on this, two types of nonwoven material (type A, type B), which differ from each other by their surface density, thickness, number of layers and the raw material composition of the inner layer, were developed
