Fiber diameter of recycled polymers and blends (50/50 and 33/33/33 wt %) at 10,000 rpm rotation speed. Polymers were melt-spun at the following temperatures: polypropylene (PP) = 230 °C, polystyrene (PS) = 260 °C, polyethylene terephthalate (PET) = 300 °C, blends = 270 °C. Error bars correspond to the standard deviation calculated from three to five replicates of each polymer.
