Abstract
Rotary forcespinning (RFS) is a method to produce fiber. This method is very efficient, low cost and very produtive compared to other method. It has high rate production than electrospinnig. This study focused on the synthesis of mixture polyvinyl pyrolidone (PVP) and Polyethylene glycol (PEG) fibers using RFS with varying rotating speed. The Fiber produced using RFS and solutions of PVP/PEG in distilled water and ethanol with concentrations 14 wt.%. The RFS process was performed at different rotational speed starting from 6.000, 8.000, 10.000, 12.000 and 14.000 rpm. The morphology and average diameter of PVP/PEG fibers was investigated using optical microscopy. Beaded fibers were at rotating speed 6.000 dan 8.000. The results showed that diameter of fibers decreased as rotating speed of RFS increased. The diameter of the PVP/PEG fibers was uniform
