m-Aramid dissolved in N,N-dimethylacetamide (DMAc), were coagulated in different coagulants such as water,
methanol, ethanol, propanol and butanol. Various concentrations and temperatures of the coagulants were also used to evaluate dyeing
properties of coagulated m-aramid films. Field emission scanning electron microscopy (FE-SEM) was employed to investigate the
surface morphology of m-aramid films. Wide angle X-ray diffraction (WAXD) was conducted in order to measure crystallinity
change of m-aramid fibers and films. WAXD patterns showed that crystallinity of m-aramid fibers was reduced after film formation.
In addition, color depth (K/S value) was measured and the results revealed that the film coagulated in water possessed fairly
enhanced color depth. |
