To provide a fluid-jetting nozzle not necessitating a special patterning treatment after an interlacing treatment, and to provide a method for producing an interlaced non-woven fabric by the use of the nozzle.

A fluid-jetting nozzle wherein plural different nozzle holes a, b, c are arranged, or a fluid-jetting nozzle wherein plural fluid nozzle holes having the same nozzle diameter are disposed at different distances. The method for producing an interlaced non-woven fabric comprises jetting a high pressure fluid on a fiber web by the use of either of the nozzles. Interlaced non-woven fabrics having various kinds of patterns are obtained only by the interlacing treatment process.
