Abstract
In this work, Polyurethane (PU) fine fiber nonwoven mats are generated using the Forcespinning® method. A detailed study focusing on the effect of PU concentration within solutions of N, N Dimethylformamide and the effect of relative humidity (RH) on fiber average diameter and fiber yield is presented. Solutions were prepared with 4 different concentrations, 14, 15, 16 and 17 wt% of PU. It was observed that as concentration of PU increases, average diameter shows a tendency to increase. Production of fibers with RH varying from X to X was analyzed. It was shown that higher RH is convenient for PU fiber production. Fibers were characterized under a scanning electron microscope to evaluate fiber size and surface features. Contact Angle measurements were also performed.as expected a dependency with fiber size was observed.
