The specific requirements imposed on dressings for the treatment of these wounds depend fundamentally on the type of lesion; moreover, they are based on the creation of an optimal environment that allows epithelial cells to move easily to facilitate regeneration. The objective of the research is to provide a multilayer medical device with composite characteristics, usable for basic medical interventions on superficial burns with thermal origin (flame and melts) occurred on anatomical regions protected by clothes (so except face and eyes). The outer, second and interfacing layers have specific characteristics. Regarding this aspect, 5 variants of woven textile structures were designed and made that differed in the nature of the raw material, the density of the length/fineness of the threads in the weft, the density in the weft and the binding. To characterize the populations of flat structures used to make the first layer of the matrix, methods specific to descriptive statistics were used. The following fundamental statistical indicators were calculated for each of the 3 variables considered defining (mass, thickness and absorption capacity): mean, dispersion and standard deviation; median and quartiles; eccentricity (skewness) and vaulting (kurtosis) for asymmetry and highlighting the cases in which interventions should be performed (on the technological flow or on the programming scheme). The results obtained by the statistical analysis of the groups of results allowed the findings to be generalized to larger populations, so for the whole set from which the respective sample was extracted. Depending on location and the severity of wounds resulting from shooting, explosions or fire (wounds that result in bleeding, impaired vital functions, the impotence of an anatomical segment, celsiene signs, etc.), the first layer of the matrix can be made of woven textile materials. After correlating the physico-mechanical characteristics of the textile structures with the subsequent processes (realization of layer II, layer III and functionalization), the technical and physico-mechanical characteristics of the multilayer matrix will be determined, and the location areas and the field of use (for haemostasis, regeneration of connective tissues or their simultaneous combination) will be established.
