ABSTRACT:
This invention relates to an apparatus and a process involving fluid jet devices for intermingling filaments of a continuous filament yarn or yarns, including combining a plurality of yarns to produce a larger coherent yarn. More particularly, the invention relates to fluid jets having a passageway through which yarn moves, where the yarn is positioned and maintained along one wall as it passes through the passageway and where the fluid-directing orifice in the jet is offset with respect to the passageway in the direction of the wall. The apparatus and the process are useful in producing heather yarns with superior yarn blending and along-end uniformity.
