ABSTRACT:
A multiplate spin pack receives metered molten polymer and metered amounts of additive components selectively proportioned to produce desired characteristics in extruded fiber. The additive components are mixed together and blended with the polymer by passage through a pattern of mixer channels formed in opposed faces of spin pack mix plates immediately upstream of the spinning orifices of a spinneret. Mixing is produced by splitting the fluids into multiple paths and repeatedly converging the paths into boundary layer contact. Short flow paths of mixed polymer minimizes time and waste in change over procedures.
