ABSTRACT:
Method to provide a novel false twisted slub yarn by combining a core yarn and an effect yarn in a fluid tangling zone. The linear velocity of the effect yarn is raised to allow slubs to be produced in the combined yarn in an air jet apparatus. The slub yarn is then run through a commingling air jet after formation of the slubs to commingle the lean portion of the yarn between the slubs formed to prevent a strip back of the yarn during weaving and/or knitting.
