Electrospinning of Fibres Using Mixed Compositions Based on Polyetherurethane and Hydrophylic Polymers for the Production of Membrane Materials

摘要

In this paper, the possibility of obtaining micro- and nanofibres, as well as nonwoven materials from polyether-urethane solutions using the method of electrospinning, was studied. The conditions and formulation-technological factors for the production of nonwaven fibrous webs from polyetherurethane (PUR) solutions modified with hydrophilic polymers: polyvinyl alcohol (PVA) and polyactylic acid (PAA) were studied. The effect of hydrophilic polymers on the structure and average fibre diameter is shown. An increase in the indicators of hygienic properties of modified nonwoven materials was revealed with the aim of their further use in membrane bags for clothes and shoes.
