Prepare polymer solution by dissolving polystyrene plastic food containers, polystyrene, poly (Oriented Polystyrene), cut into small pieces. The concentration of poly styrene, 15, 20, 25 and 30 percent by weight (% w / w) in a solvent type include 1,2-Dichloroethane, Dimethyacetamide (DMA) and Methylethylketone (MEK) at. respectively, at room temperature Then stir until a homogeneous solution. ** When the roller striped poly styrene homogeneous make injection molded fiber immediately.
