In a dry spinning process for producing an elastane multifilament yarn, in which an elastane solution is dry-spun to form the yarn, the improvement comprises reducing or preventing interfilamentary adhesion by: using at least one multihole spinning jet whose individual capillaries are located on one plate, whereby the distance between the capillaries is specified; laminarizing the gas flow in the dry spinning apparatus to prevent entangling of the individual filaments from adjacent multihole jets; passing the elastane yarns through a first yarn guide with one opening per individual filament and then through a second yarn guide which gathers the filaments together; and winding up the multifilament yarn. The resulting elastane filaments do not adhere to each other. IPC D01D D01F.
