WebIn melt spinning, the polymer pellets or granules are fed into an extruder consisting of a screw for melting by means of heat, and then the polymer melt is pumped through a spinneret under pressure. The extruded polymer is then quenched with cold air and the molten mass is solidified into filaments. WebAs the web fluid exits the spinneret holes, it is attracted to itself electrostatically, and thus can form complex shapes. The spinneret holes have three sets of adjustable, staggered openings around the turbine which permit a single, incredibly strong line; a more complex, spreading spray; and a thick, tremendously adhesive liquid.
