Abstract
A false-twist nozzle with an improved structure is provided herein. The false-twist nozzle according to the invention comprises a housing having a large-diameter yarn passage portion and an insert member having a small-diameter yarn passage portion and a fluid conduit hole. When the insert member is within the housing, a complete yarn passage hole is formed through the nozzle. Because the insert member is separable from the housing, drilling of the very small diameter fluid conduit hole can be made easily and accurately prior to insertion within the housing. Furthermore, the fluid conduit opening is disposed both annularly and angularly in the downstream direction with respect to the yarn passage hole, thereby increasing the twisting action induced by the flow of jetted fluid while preventing damage to the yarn.
