    • The present invention relates to a nozzle suitable for jetting high pressure and high temperature steam, and a method and an apparatus for producing an entangled nonwoven fabric using the nozzle. According to the apparatus, a steam inlet side main conduit and a steam outlet side conduit are connected with both end parts of a tubular nozzle holder in a longitudinal direction provided integrally with nozzle members having a plurality of nozzle holes. A steam outlet side conduit is provided with an opening/closing valve and a trap conduit is branched from a conduit at an upstream side from the opening/closing valve. By opening the opening/closing valve, a rapid temperature rise of the nozzle holder can be enabled at a time of starting a production of a nonwoven fabric. Furthermore, even in the opening/closing valve is closed in a regular operation, drainage generated inside the nozzle holder can always be discharged to outside so that steam can be jetted stably and continuously, and thus a high quality entangled fiber nonwoven fabric can be produced continuously from the fiber web by the steam.
    • 本发明涉及适用于喷射高压高温蒸汽的喷嘴,以及使用该喷嘴生产缠结无纺布的方法和装置。 根据该装置,蒸气入口侧主管道和蒸汽出口侧管道与管状喷嘴保持器的两个端部沿长度方向连接,与具有多个喷嘴孔的喷嘴构件一体地设置。 蒸汽出口侧管道设置有开/关阀,并且捕集管道从开/关阀的上游侧的导管分支。 通过打开开关阀,可以在开始制造无纺织物时能够使喷嘴保持器快速升温。 此外,即使在正常操作中关闭开闭阀时,也能够始终将喷嘴保持架内部产生的排水排出到外部,从而可以稳定且连续地喷射蒸汽,能够制造高品质的缠结纤维无纺布 通过蒸汽连续地从纤维网。

    • The present invention relates to a nozzle suitable for jetting high pressure and high temperature steam, and a method and an apparatus for producing an entangled nonwoven fabric using the nozzle. According to the apparatus, a steam inlet side main conduit (c1) and a steam outlet side conduit (c3) are connected with both end parts of a tubular nozzle holder (11) in a longitudinal direction provided integrally with nozzle members (15, 16, 23) having a plurality of nozzle holes (16a, 26). A steam outlet side conduit (c2) is provided with an opening/closing valve (55) and a trap conduit (57) is branched from a conduit at an upstream side from the opening/closing valve (55). By opening the opening/closing valve (55), a rapid temperature rise of the nozzle holder (11) can be enabled at a time of starting a production of a nonwoven fabric. Furthermore, even in the opening/closing valve (55) is closed in a regular operation, drainage generated inside the nozzle holder (11) can always be discharged to outside so that steam can be jetted stably and continuously, and thus a high quality entangled fiber nonwoven fabric can be produced continuously from the fiber web by the steam.
