Abstract (en)

[origin: WO2022034051A1] The invention relates to an interlacing jet (100) for producing yarns with nodes, interlaced yarns, DTY or flat yarns with nodes. The interlacing jet (100) comprises a yarn channel (1) with a air spin chamber (2). The air spin chamber (2) comprises an in-flow opening (4) for introducing air into the air spin chamber (2). A channel axis (M) extends in a thread guiding direction (F). The yarn channel (1) comprises a channel width (21) transverse to the channel axis (M). The air spin chamber (2) comprises a chamber length (29) in the thread guiding direction (F) and a chamber extension (28) transverse to said length. The chamber length (29) is at least 180% of the chamber extension (28), preferably at least 200% of the chamber extension (28), and the chamber length (29) is preferably at least 1.5 mm longer than the chamber extension (28).
