| Abstract | The melamine fiber has been widely used because of its excellent flame retardancy. We tried to fabricate melamine fibers using ionic liquids (ILs) as solvents, melamine formaldehyde resin prepolymer (pre-MF) as flame-retardant material, and cellulose as the supporter. The best ILs for dissolving water-insoluble pre-MF were screened by COSMO-RS, in view of the richness of ILs and the complexity of pre-MF. The logarithmic activity coefficients (ln gamma) of three models were calculated to evaluate the dissolution ability of pre-MF in 432 ILs. According to the results of ln gamma and excess enthalpies, anions play a leading role in the dissolution process of pre-MF in ILs, while cations have little effect on it. The solubility experiments of pre-MF in 8 ILs were determined, which are consistent with the trend of ln gamma predicted. It is important that the ILs composed of OAc-, Dec(-), HCOO-, DEP-, DBP-, DMP-, Ben(-), Cl-, and Br- and different cations studied in this work have good dissolution ability for pre-MF. Besides, MF/cellulose composite flame-retardant fibers were prepared finally using EmimDEP as the solvent and cellulose as the supporter with good mechanical properties and flame retardancy: the breaking strength and limiting oxygen index are 2.24 cN/dtex and 31%, respectively. |
