Nonwovens produced through electrospinning technique have been successfully used in various fi elds due to their unique properties. It is essential to investigate the impact of the parameters in the manufacturing process on the resulting properties of these materials. This research focuses on nonwovens made from fl uoroplast P(VDF-TFE) using a horizontal spraying system with a vertically positioned collector. The parameters studied include the interelectrode distance, the electric fi eld strength, and the viscosity of the molding solution.

A comparative evaluation of the sorption capacity of synthetic and natural sorbents with respect to phenol and some of its derivatives has been carried out. Electrospun nanofi bers based on polyamide-6 (PA-6) were obtained under optimal conditions from a spinning solution of a polymer dissolved in a mixture of formic and acetic acids. The preparation of the clay mineral by the sieve method has been carried out, while the enriched fraction of glauconite (200–500 microns) has been isolated.
