Evaluation of Diluted Cellulose Solutions for Nanofiber Production using the Electrospinning Method

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.

Hybrid Fiber Materials according to the Manufacturing Technology Methods and IOT Materials: A Systematic Review

“…The samples obtained through electrospinning were observed via SEM, and the spinning dope was obtained using N-methylmorpholine, N-oxide, and viscose methods. Based on studies conducted with phosphoric acid mixtures not commonly used in the industry, Laszkiewicz et al argued that the cellulose solution of NMMO(N-Methylmorpholine N-oxide) could be demonstrated to be a good system for the stable formation of nanofibers using static electricity [ 3 ].…”

“…Consequently, smart wear is becoming an item that will dominate the fiber material industry in the future. Hybrid fiber composites can have various applications, such as in healthcare, defense, fashion and entertainment, sportswear, purpose clothing, and transportation, as well as integration with advanced technology [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. To date, research on cutting-edge hybrid fiber materials is being conducted [ 4 , 5 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ].…”
