A method of treating filament yarn includes supplying a plurality of yarn filaments through a yarn channel of a nozzle in a yarn travel direction and introducing a blowing medium into the yarn channel substantially in a direction of the yarn travel direction and at an angle of introduction of more than about 15&deg; and less than about 45&deg; from a direction perpendicular to the yarn travel direction. The plurality of yarn filaments are mixed within the yarn channel so as to produce a filament yarn substantially free of knits.

Method and device for processing filament yarn, and use of said device

The invention relates to a pin assembly which keeps single-piece, two-piece or multi-pieced yarn processing elements, especially yarn interlacing spinnerets or thermal treatment elements, in an exact position during an entire service life, despite the extreme effects of preparations used. Instead of a traditional soldered joint or an adhesive connection, mechanical clamping means are used to fix the dowel pins to one part of the spinneret. Fixation of the dowel pins is not affected by heat or chemical preparations. The clamping means consists of a simple clamping ring holding the dowel pin in position directly inside the body of the spinneret between the clamping pin and an after-body. The novel positioning solution can be used with individual parts of spinnerets, parts of spinnerets in machines or multiple parts of spinnerets. The dowel pins enable the entire spinneret to be substantially miniaturized and allow narrow separation between various yarn runs, which was previously impossible. The invention can be used advantageously in interlacing spinnerets or in stream treatment elements.
