Abstract
A yarn entangling jet has a yarn passageway extending therethrough and an air inlet passageway communicating with an outlet portion of the yarn passageway adjacent the junction with an inlet portion thereof. The outlet portion is preferably of triangular cross-section, comprising a base wall opposite the air inlet passageway and two converging side walls. The inlet portion has one wall coplanar with the base wall and an inlet surface which converges towards the base wall in the direction towards the junction with the outlet portion. An inlet yarn guide is positioned to ensure that the yarn approaches the base wall at the desired angle less than 180.degree.. The jet is in two parts secured together with a threading slot therebetween at one side of the yarn passageway spaced from the base wall towards the apex of the outlet portion.
