摘要

Process for the production of a composite yarn, of novelty or effect, characterized by comprising the phases of: A) conducting a continuous multifilament base yarn with just a continuous multifilament fancy yarn through the fabric blowing nozzle under an adjustable pressure of a fluid medium capable of causing an interlacing action and a suction action when applied to said yarns, at least said base yarn consisting essentially of textured filaments; B) varying the pressure of the fluid jet applied to said wires, between a low value above atmospheric pressure and a clearly higher value; C) maintaining a relatively high tension on said base yarn so that it follows a substantially linear path through the blowing nozzle; D) maintaining a fancy yarn tension clearly low compared to the tension on the yarn base, by a slight brake of said fancy yarn during the application of said low value of the nozzle pressure; y E) keeping the fancy yarn practically free of tension and without brake, during the application of said high value of the pressure in the nozzle.
