Figures 1 to 3 show examples in which a false twisting nozzle with a sound reduction chamber according to the present invention is implemented in a binding spinning machine. In this case, FIG. 3 is a side sectional view of a binding spinning device in which two false twisting nozzles are successively provided for spinning. Also, Figures 4 to 8 show relevant parts of the conventional device. Figures 4 and 5 are side sectional views when two false-twisting nozzles are provided, and Figure 6 is a side sectional view when two false-twisting nozzles are installed. FIGS. 7 and 8 are front sectional views showing the opening state of the air injection holes taken along the AA cross section and the BB cross section in FIG. 5, respectively. 1: Front roller, 2: False twist nozzle, {3,

撚ノズル。[Scope of Claim for Utility Model Registration] (1) In a binding spinning device that twists fiber bundles using a false twisting nozzle, there is a cut-off at the outlet of the false twisting nozzle for binding and spinning, which is disposed behind a pair of front rollers. A false twisting nozzle for bundled spinning, characterized by having a sound reduction part whose area has been rapidly expanded. (2) At the yarn passage outlet of the false twisting nozzle, the distance l from the rear end of the yarn passage large-diameter hole where the injection hole is opened to the front end of the sound reduction part is 2 to 8 times the diameter d of the large-diameter hole. The first claim for utility model registration characterized by
False twisting nozzle for bundled spinning as described in . (3) At the yarn passage outlet of the false twisting nozzle, the depth t in the axial direction of the sound reduction part is 1.
The false twisting nozzle for bundled spinning according to claim 1, which is configured to provide a step that suddenly expands from the front end entrance of the sound reduction part when the ratio is 5 times or less and 0.5 times or more.
