The effect yarn is drawn at no higher than a normal drawing ratio for material from which the effect yarn is made and the effect yarn is softened by sufficient heating, in order to prevent rupturing of the effect yarn during drawing.

The core yarn can also be drawn at or below its normal drawing ratio in order to aid in developing thread tenacity and ensure an acceptable elongation at break after dyeing or subsequent wet processing.

Abstract: A method and apparatus for producing novelty yarn with an unusual configuration. An effect yarn is fed to a novelty yarn jet, and a core yarn is fed to a different yarn port in the same jet, the core yarn being maintained substantially taut. The combined core and effect novelty yarn is taken up from the jet and periodically (preferably pseudo-randomly) a pronounced variation in linear density is provided in the combined yarn. This linear density variation is accomplished by introducing a first fluid pulse into the jet at a first position to form a loop in the effect yarn, which loop extends substantially coincident with a portion of the core yarn, and then utilizing a second fluid pulse at a spaced position from the first pulse to impart a spiraling and/or rotating action to the loop of effect yarn to wind the effect yarn around the core yarn.
