| Abstract | ||||
| Producing a valuable nanofibers can occurs by electrospinning, as it consider one of advanced spinning techniques that can obtain functionalized fibers for smart application. The current work demonstrated for new exploration of electrospinning process of cellulose acetate (CA) from trisolvent mixtures. 5% water added to stable CA Electrospinning solution that contains DMAc/AC (1:2). Five different speeds 6, 12, 22, 32 and 40 ml/hr were applied to CA solution. The reflectance of water addition on electrospun fiber properties on fiber diameter and homogeneity was visualized using SEM and Mechanical properties also Contact angles of the preformed nanofibers were characterized. In addition to air permeability test were also evaluated. The obtained fibers showed different morphology against spinning rate. Surface behavior of spun fibers is nearly similar to pristine cellulose acetate (CA) fiber spanned from di-solvent. Spinning rate affects positively on tensile properties and negatively on elongation modulus. The spinning rates indirectly proportional to fiber diameter that reflected on the air permeability. Spinning rate 22ml/hr showed the optimum velocity for spinning from tri-solvent CA solution. Conclusionally, the obtained results open the door for high speed electrospinning process saving time and cost achieving the research target. | ||||
