nature : the polymer solution is above the boiling point solvent and the temperature under high pressure by the spinneret extrusion pressure to achieve the spinning method. When spinning out of silk when spinneret, due to a sudden pressure drop, the rapid evaporation of solvent, the resultant fine silk. This method can also be used for producing superfine fiber. This process, in an instant, therefore, also known as transient spinning (instataneous spinning). Fiber orientation is derived from the micro-fiber structure, tensile, after the high intensity. For example, polyethylene used for three chlorine solvents can apply this spinning.
