ABSTRACTThis article concerns the process of obtaining fibers made of sodium alginate containing nanosilver. The general objective was to select the proper forming parameters in order to obtain possibly high rates of tensile properties. The specific objective of this investigation was to determine the effect of basic forming parameters on the macroscopic structure, as well as the determination of the tensile, sorption, and resistivity properties of the obtained fibers. The porous structure and morphology studies were carried out by X‐ray diffraction WAXS. Cross‐sectional and surface analysis was carried out by SEM (scanning electron microscope) and AFM method (atomic force microscopy). SEM (Scanning electron microscope) + EDS (energy‐dispersive X‐ray spectroscopy) analysis was applied to assess the uniformity of distribution of nanoadditives on the fibers’ surface, and FTIR spectroscopy was applied to confirm the chemical structure of fibers. Within the framework of this article, the impact of specific nanoadditives on the properties of the obtained fibers was also examined.
