Effect of Experimental Parameters on the Morphology of Electrospun Nylon 6 fibres

Electrospinning is a unique way to producing novel polymer nano fibres with diameter typically in the range from 10 nm to 1500nm. Large length to diameter ratio and small mass to volume ratio of these nanosizes fibres widens the areas of their application to many industrial uses. Nylon 6 nanofibres with diameter ranging from 150nm to 1300 nm were produced by the electrospinning process. The fibre diameter was varied by adjusting the concentration of the polymer solution between 15wt%-25wt.% in formic acid. The fibres were obtained by electrospinning from solutions in formic acid at various concentrations. Polymer concentration, viscosity, surface tension, electrical conductivity of the solution was found as the dominant parameter to control the fibre formation. The morphology of the processed fibres has been examined by microscopic techniques (SEM) and optimized by changing process parameters. Index Term-Electrospinning, nanofibres, process
