Today, many scientists study properties of nanofiber textiles. These properties are determined by the unique structure of nanotextiles and, therefore, it is necessary to know exactly how the structure of the fabric looks like. Nowadays, a few models are used, but they are inaccurate. The lack of an appropriate model of nanofiber textile was the main motivation of this research.For our study we have chosen nanotextiles made of two polymers: PVDF (polyvinylidene fluoride) and PUR (polyurethane). The nanotextiles were produced at Czech Technical University in Liberec by NS 4S1000U device using Nanospider technology.In this research, the structure of the fabrics was analyzed using an electron scanning microscope Tescan Maia 3. Two sets of the experiments have been carried out. In the first experiment the surface structure of the samples was studied. Photos created by SEM were analyzed using program Atlas and image editor GIMP. In this set of the experiments the initial parameters for the creation of a digital 2D model of a single layer have been determined (fiber size distribution, pore size and curvature of the fibers). In the second set of the experiments cross sections of nanofiber textiles were made in order to study the inner structure of the fabric. This information allows evaluation of the total number of 2D layers in the model and, thus, is very important for future creation of a 3D model of the fabric.Keywords: Polymer, SEM photography.
