Abstract
In order to prepare PAN nano fiber web, PAN/DMF solution was prepared and electrospun. The diameter of fiber was depended on the polymer concentration (7.5-15wt%) and the applied voltage (10-16kV). The average diameter of fiber increased with an increase of the polymer concentration and decreased with the applied voltage. At 7.5wt% concentration, many beads were found. So, we prepared a nano PAN fiber by electrospinning at concentration of 10wt% and 16kV. PAN fibers were reduced with litium aluminium hydride and the dyeability to acid dye was checked. The reduced nano PAN fiber showed much better dyeability compared with the reduced ordinary PAN fiber. It was considered that the increase of specific surface area have an important role in dyeing with acid dye.
