ABSTRACT:
Additives are introduced into a thermoplastic melt by feeding at least one additive in an aqueous vehicle containing a dispersant to form an aqueous additive stream to a vented extruder which is extruding a thermoplastic followed by volatilizing an aqueous portion of the aqueous additive stream and removing substantially all the volatilized aqueous portion through the extruder vent to achieve a substantially homogeneous system containing the thermoplastic and at least one additive and forming a fiber from the homogeneous system by extrusion of the system through a spinneret.
