Evaluation of Diluted Cellulose Solutions for Nanofiber Production using the Electrospinning Method
Journal Title: Fibres and Textiles in Eastern Europe - Year 2017, Vol 25, Issue 6
Abstract
This paper discusses the possibility of nanofibre formation in an electrostatic field from cellulose solutions in different solvent systems. Additionally when investigating solutions of various cellulose content, an attempt was made to evaluate these solutions from the viewpoint of their usability for nanofibre formation. The spinnability of the solutions examined was assessed based on observation of the stability of nanofibre formation by the simplest single needle spinning device. The morphology of the samples obtained by electrospinning was studied by Scanning Electron Microscopy (SEM). Spinning dopes were obtained using well-known technologies for cellulose solution preparation applied in the cellulose fibre industry, namely N-Methylmorpholine N-oxide (NMMO) and viscose methods, as well as a mixture of phosphoric acids, which is relatively cheap, easily available and yet not used in industry. Based on the research conducted, it may be concluded that the cellulose solutions in NMMO proved to be the best system for exceptionally stable formation of nanofibres in an electrostatic field.
