Abstract
A method for forming a slub yarn uses conventional false-twist texturing apparatus in combination with one or more air jets to impart striations and/or neps and slubs to continuous filament yarns. Three process configurations are disclosed; each configuration uses one air jet through which yarn passes and which directs turbulent air in a direction opposite to the direction of travel of the yarn.
