ABSTRACT:
A method for interlacing or entangling continuous multifilament synthetic yarn wherein the yarn to be interlaced is fed along a feed path through a yarn feed bore to a jet nozzle member defining with a surrounding housing and an outlet tube member a shaped turbulence chamber within the housing at the exit of the yarn feed bore in the nozzle member. The jet nozzle member has one or more jet passages directing fluid from a pressurized air chamber into the turbulence chamber along jet axes inclined to the yarn feed axis and offset sidewise in non-intersecting relation thereto to produce interlocking entanglements of filaments of the yarn during passage therethrough.
