Abstract

A yarn texturing nozzle is disclosed which comprises a yarn feeding inlet portion wherein a yarn is subjected to a heated and pressurized treatment fluid to heat the yarn and also advance the yarn therethrough. The nozzle also includes a stuffer box located downstream of the inlet portion. The inlet portion comprises a rectangular block which is divided into two parts along a plane extending coaxially through the yarn passageway to facilitate yarn threadup, and the stuffer box includes a slot through the side wall thereof which further facilitates yarn threadup.
