ABSTRACT:
Nonaqueous additive systems which includes dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier are added directly to a melt flow of a polymeric host material prior to spinning. The additive system is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymeric material, melt-spun filaments having different additive attributes may be produced on a continuous basis (i.e., without shutting down the spinning operation).
