The invention concerns a yarn treatment device, in particular by air turbulence of continuous yarns. Said device comprises at least a yarn channel (4) whereof the inner wall has a yarn guiding zone with which the yarn (7) is in contact when it passes through the channel (4). The invention aims at using such a yarn treatment device to reduce adherence effects to the wall between the yarn (7) and the yarn guiding zone of the channel (4). Therefor, the inner wall of the channel (4) is provided, in the yarn guiding zone, with at least two protuberances (8) projecting in the channel cross-section. The yarn travelling through (7) is in contact with said protuberances at a short distance from inner wall of the channel (4). |
