    • PROBLEM TO BE SOLVED: To provide a compressed fluid processing nozzle for removing particular monomers deposited on the inner circumferential surface of the yarn inlet hole of a jet core and the front and rear vertical surfaces adjacent to the inner circumferential surface, and for accomplishing its longer service life.
      SOLUTION: The compressed fluid processing nozzle 5 comprises a nozzle housing 7 and the jet core 9 provided in the nozzle housing 7 and having the yarn inlet hole 11 for feeding yarns C1 and E1 to be processed and an air jet hole 29 for feeding air. This nozzle 5 has such a mechanism as to feed yarns into the yarn inlet hole 11 and subject the yarns to textured processing so as to give slacks and/or loops in the longitudinal direction of the yarns by feeding air into the air jet hole 29. This nozzle 5 is characterized in that the inner circumferential surface 11A of the yarn inlet hole 11 of the jet core 9 and the front and rear vertical surfaces 11B and 11C adjacent to the inner circumferential surface 11A are coated with diamond-like film 41, diamond film 43 or the like as carbon-containing film, or titanium carbide or titanium carbonitride 45.
