摘要： A card wire (110) is comprising an elongated rib portion (112) and teeth. The teeth are having a front portion (114) and a back portion (116). The teeth are hanging over towards their front portion (1 14). The front portion (114) and back portion (116) are merging at the tip (118) of the tooth. The front portion (114) comprises at least three sections: a first section (120) extends from the tip (118) of the tooth in the direction of the rib portion (112), a second section extends below the first section (120) in the direction of the rib portion (112) and a third section (126) extends from the end of the second section in the direction of the rib portion (112). The second section comprises a straight part (122) and a curved segment (124), wherein the straight part (122) is having a minimum length of 0.10 mm and the straight part (122) is having an angle between 10 and 30 degrees relative to the length direction of the card wire. The straight part (122) is followed by the curved segment (124) wherein the curved segment (124) is having a radius (R) of at least 0.18 mm.
