Linear abrasive brush member, method for preparing linear abrasive brush member, and abrasive brush

摘要

To provide a linear abrasive brush member, in which filament parts are hardly broken, a substrate part is excellent in deformability, and also, abrasion ability is excellent. A linear abrasive brush member comprising: an embedded core material (9); a rod-shaped substrate part (7) having opposite long-narrow upper and bottom faces; and a plurality of filament parts (8) present on the upper surface along the longitudinal direction; and the substrate part and the filament parts being integrally molded from a resin composition.
