Abstract

This study investigated the effects of processing parameters on the fiber morphology of electreospun cellulose acetate from Musa textilis Nee. Cellulose acetate was produced using processes. The cellulose acetate was characterized using FTIR spectroscopy. The degree of substitution was also determined. Nanofibers were produced using a fixed mixture of dicholomethane (4:1 volume ratio). Processing parameters e.g. concentration, voltage, flowrate and tip to collector distance were altered to determine the optimal conditions. The results of the study revealed the amount of cellulose acetate produced id dependent on the process used. The yield were 20.22 and 127.78%, respectively. The IR spectra proved that indeed cellulose acetate was produced and the average degree of substitution was 2.60. Electrospinning of abaca cellulose acetate can best be done at of 7.5% w/v polymer concentration, 20kV voltage, 7mL/h flow rate, 15cm distance. The fiber diameter ranged from 393 to 1180 nanometers with an average of 741.5 nanometers.
