ABSTRACT:
A process for producing a composite novelty or effect yarn comprising a base thread and a fancy thread combined therewith in a texturizing jet nozzle having both an interlacing effect and a suction effect and operated between a low jet pressure and a high jet pressure, the low pressure being applied while the fancy thread is conducted through the jet nozzle under a lightly braked, lower tension than that applied to the base thread, and the high pressure being applied while the fancy thread is conducted through the jet nozzle under practically unbraked, tension-free conditions. The resulting product is useful as a doupion-type novelty yarn which provides commercially valuable effects in woven fabrics.
