Development of new materials is still growing up. The relatively new materials are nanofibers membranes. These fabrics are very popular due to their properties, which primarily depend on the structure of the material. This structure may be affected by several parameters. Setting of production parameters of the spinning device have a major impact on the structure of the fabric. The analysis of this effect is the main goal of this work.In this paper nanofiber textiles were manufactured by using the device NanospiderTM NS LAB 500 S (Elmarco, CR). As the main spinning polymer was used polyvinyl alcohol (PVA). We created 15 types of textile where technological parameters were changed. This work contains two experimental parts. In the first one, we analyzed the effect of voltage, distance of the electrodes and the solution concentration. There were not achieved fundamental changes in the structure of the fabric. In the second experiment, we tested the effect of changes of the electric field to change the structure of the resulting nanofiber membranes. The structure was analyzed using a scanning electron microscope Tescan Maia 3. In this experiment, we achieved significant changes in structure and thus we demonstrated the significant influence of adjustment of the electric field on the final fabric structure.Keywords: Nanospider, nanofiber membrane, structure, production parameters
