In order to apply pressurized steam to the running yarn, it is necessary to form an atmosphere system in which the steam leaks as little as possible and allow the yarn to run therein. For this reason, generally, a pressure steam processing apparatus having labyrinth nozzles provided before and after the pressure steam processing chamber is used. The yarn enters from the labyrinth nozzle portion on the inlet side, is stretched in the pressure steam processing chamber, and exits through the labyrinth nozzle portion on the outlet side.

The pressure steam b flows into the pressure chamber 3 from the steam inlet 2, passes through the perforated plate 4 and reaches the pressure steam processing chamber 1. Here, the yarn a is subjected to a drawing treatment and leaks to the outside through the front and rear labyrinth nozzle portions 5 ′ and 6 ′.

At this time, the yarn a vibrates due to the steam b leaking to the outside, and the yarn a comes into contact with the inner wall of the labyrinth nozzle 10 to cause damage or fluff on the yarn a. If the inner diameter of the labyrinth nozzle 10 is reduced to suppress the vibration of the yarn a, steam leak can be reduced, but the chances of contact between the yarn a and the inner wall of the labyrinth nozzle 10 increase. Also,
When the inner diameter is increased, the vibration of the yarn a becomes extremely large due to the turbulent air flow when steam leaks, and the leaking steam deteriorates the work safety.

As described above, the steam supplied into the pressure steam processing chamber often leaks from the labyrinth nozzle portions at the front and rear, which disturbs the running of the yarn. This yarn disorder is so great that steam leaks out so much that a part of the yarn comes into contact with the inner wall of the nozzle, damaging the fiber surface, and causing yarn breakage and fluff. For this reason, the filling rate of the yarn in the nozzle is reduced, that is, the nozzle diameter is increased in order to avoid this, but the amount of steam leakage increases, and the disorder of the yarn due to the turbulent air flow becomes rather severe. On the contrary, if the filling rate of the yarn is increased, that is, the nozzle diameter is reduced to suppress the leakage amount, the possibility of contact with the inner wall becomes large, and the yarn breakage and the fluffing also increase. In addition, the large amount of high-temperature steam leaking also poses a problem in terms of work safety.

On the other hand, in the threading operation, air sucker used for ordinary fiber operation is applied to the yarn outlet to perform the suction operation, but the suction efficiency is poor and the filling rate of the yarn must be lowered. Also, when using multiple threads,

When the gas is injected from the gas inlet on the downstream side of the steam, a part of the gas leaks from the outlet of the labyrinth nozzle. The other gas flows toward the upstream side of the steam, balances the steam flowing out from the pressurized steam processing chamber, and is discharged from the gas outlet as a mixed gas of steam and gas. Therefore, leakage of steam from the labyrinth nozzle outlet is suppressed. Further, by providing an air ejector at the yarn outlet, it is possible to perform a suction operation of the yarn only by temporarily circulating compressed air during the threading.
