| Summary: | 碩士 === 逢甲大學 === 紡織工程所 === 95 === Electro-spun technical principles had been studied and applied at present. Some problems need to surmount for industrialization, such as low throughput, variation of fiber diameter and base weight etc.
This study included three steps for industrialization of electro-spun process to solve above problems for nano-fiber film. The condition of 5% wt of PEO solution (Mw：300,000 g/mole) was used in this study．First, the suitable collector and supporting media were established through full-factorial experiments and images analysis. An non-embossed spun-bond nonwoven was used as a supporting media and a flat metal plate was selected as a collector in this study. Second, the optimum electro-spun parameters were found by using a full-factorial experiment for varied paraments of working voltage/ throughout/ distance between spinneret and collector (CSD) by a SEM analysis. Results showed that the average fiber diameter was 578.69 nm and variation CV% of fiber diameter was 13.405% at the condition of 42 cm CSD and 41 kV working voltage and 0.3573 ml/min throughput. Thirdly, trial-run with the results of first and second steps, the filtration efficiency was 91.2% with a pressure drop 13.8 mm-H2O by TSI 8130(32LPM, NaCl) analysis.
