Résumé
A wet type solution blow spinning system with a water-mist coagulation chamber was developed to spin fine regenerated cellulose fibers from the non-volatile ionic liquid solvent 1-ethyl-3-methylimidazolium diethyl phosphate. The molecular weight distribution of cellulose, and the rheological properties and spinnability of its spinning solution were evaluated. Scanning electron microscope observations indicated that the fine water mist/vapor was important for efficient coagulation of the stretched solution jets. Under optimized spinning parameters, a non-woven fabric was obtained consisting of fine fibers with an average diameter of 0.98 ± 0.62 μm. The tensile strength of the samples was greatly influenced by the fabric structure formed upon regeneration of cellulose from solution. X-ray diffraction and polarized optical microscopy measurements revealed that the prepared cellulosic non-woven fabric was highly crystalline and had a well-defined molecular orientation, respectively, which might have contributed to the increased tensile strength.
