摘要： A barbed monofilament and a method for making the same is provided. The barbed monofilament has a substantially triangular primary cross-section defined by a periphery including first, second and third points of said triangle, and further has a plurality of barbs formed therein. Successive barbs are staggered around the periphery of the monofilament, and extend inwardly into the monofilament to a predetermined depth from the first, second and third points respectively.
