Modification of Polyurethane Solutions by Means of a Hard Depositor for Fibre Production by the Electrospinning Method

The article is devoted to fundamental and applied research in the field of the processing of polymer solutions. The purpose of this work was to identify the possibility of using modified solutions of polyurethanes for processing by electrospinning, and also to study the impact of the composition of the moulding solution on the structure and properties of fibrous materials. Nonwoven materials were obtained by electrospinning fibers from PUR solutions using NanospiderTM technology. The transfer of solutions into a metastable state, both in the case of film systems and fibres, leads to a change in the structure of the material: porosity and fiber diameter.
