Material
Flagged Polyester Filament
Flagged Polyester Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Material name alone is not enough to set stiffness; we also need filament diameter, free trim, density, grade, and working conditions.
Material Overview
Flagged Polyester Filament is a flagged polyester filament used as brush fill or a cleaning-contact element.
In a finished brush, Flagged Polyester Filament does not create a fixed stiffness by itself. Filament size, exposed length, density, tuft layout, and contact setting control the brush feel, while grade and service conditions control long-term behavior.
