Abstract

The metallic card wire (100) comprises a rib portion (110) and a plurality of teeth (115). The teeth have a tip segment (117), a front portion (120), a back portion (130), two sides (141, 142) and an interconnection section (150). The interconnection section connects the back portion of a tooth to the front portion of the previous tooth. The tip segment is where the front portion and the back portion merge. The teeth are leaning in the longitudinal direction of the card wire. The front portion is where the teeth are leaning towards the longitudinal direction of the teeth. The front portion comprises an undercut segment (160), which is a segment of the front portion of the card wire where the included angles of the tangents to the front portion with the longitudinal direction of the card wire are smaller than the included angles of the tangents to the front portion with the longitudinal direction of the card wire in a zone between the undercut segment and the tip segment of the card wire. At least one side of the teeth comprises at least one structural element (174) for increasing the frictional force of fibers relative to the side of the teeth. The at least one structural element is positioned closer to the tip segment compared to the position of the undercut segment.
