Methods of making pigmented filaments

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