Abstract Filament yarn (50) is intermingled, relaxed or heat set at melt spinning by passing it through a chamber (80) supplied with at elevated temperature and pressure, e.g. steam. The gas escapes through the entry (83) and exit (84) holes for the yarn. The h are 01 to 1 mm<2> in section compared with the much larger section, e.g. 10 to 30 mm<2>, of the chamber Independent claims are also included for intermingling, relaxing or heat setting yarn at melt spinning with such an arrange and for an intermingled yarn which does not lose more than 50% of its intermingling points at a tension of 0.5 cN/dtex.
