“…Up to now, only Badische Anilin‐und‐Soda‐Fabrik (BASF) has achieved the industrial production of MF fibers by adopting the centrifugal spinning method to produce short fibers (named Basfil) 5–7 . Owing to Basfil's dispersed diameters and poor mechanical properties, which limits its development and application, Basfil can just be used for blending with other chemical fibers 8–10 …”

In order to address the poor spinnability of melamine formaldehyde (MF) resin spinning dope, 1-ethyl-3-methylimidazolium diethylphosphate ([Emim]DEP)/H 2 O solution is first used as the solvent to synthesize MF resin prepolymer (pre-MF) solution. The pre-MF solution can be directly spun into fibers without any fiberforming agent. The influence of synthetic parameters, such as reaction time and temperature, the mass ratio of [Emim]DEP to H 2 O, and solid content, on the fiber properties are investigated systematically. The results show that [Emim] DEP demonstrates a key role in regulating the molecular weight and distribution of pre-MF solution, which plays transfer catalyst effect during the synthesis process. Furthermore, programmed heating is the most helpful for the linear growth of the molecular in the initial stage of curing and the formation of the final cross-linked structure. The fibers obtained under optimal conditions have excellent mechanical properties, with fracture strength of 323.8 MPa and elongation at break of 7.2%. This work provides a novel synthesis method of pre-MF solution to prepare high-performance MF fibers.
