Chang, F. C., Chan, K. K., and Chang, C. Y. (2016). "The effect of processing parameters on formation of lignosulfonate fibers produced using electrospinning technology," BioRes. 11(2), 4705-4717.


Lignosulfonate fibers were produced using electrospinning technology, a method of manufacturing fibrous materials using polymeric solutions, by adding traces of polyethylene oxide to lignosulfonate solutions. Continuous and uniform fibers were obtained under appropriate processing conditions. Solution concentration, applied voltage, flow rate, and syringe-to-collector distance all had effects on fiber formation and diameter. Certain interactive effects among these processing parameters were also observed. Solution concentration was the most significant parameter influencing the diameters of the resulting lignosulfonate fibers. Higher solution concentrations resulted in greater fiber diameters. A broader distribution of fibers was observed as the solution concentration increased. Applied voltage, flow rate, and syringe-to-collector distance had moderate effects on the fiber diameters, and needle gauge had a minor impact on the fiber diameters.
