2. Description of the Related Art Conventionally, a liquid, for example, water is applied to a filament yarn as required by a liquid application means, and a compressed fluid processing nozzle is used to perform a compressed fluid processing process so that a uniform loop or a continuous loop is formed in the longitudinal direction of the filament yarn. As a method for obtaining a bulky yarn having entanglement, slack, and the like, and a compressed fluid treatment nozzle used in the method, JP-B-34-8969 and JP-B-Sho 3-9
JP-A-5-6684 is known.

[0003]

In the meantime, the above-mentioned conventional means for applying water to obtain a bulky yarn includes a raw oil agent, a raw monomer or oligomer applied to a filament yarn, a calcium salt and a magnesium salt in the applied water. Deposits such as deposits accumulate in the yarn passage of the jet core constituting the compressed fluid processing nozzle, especially inside the entrance side of the jet core, and the traveling tension of the filament yarn during the compressed fluid processing in a relaxed state gradually increases. As a result, loop unevenness and entanglement unevenness in the longitudinal direction of the bulky yarn occur, and processing stability and yarn quality stability decrease. Therefore, it was necessary to remove the nozzle once every 1 to 1.5 days to clean the jet core in particular.
Therefore, there has been a problem that productivity cannot be improved.

[0004] Further, since the deposits adhere to the yarn passage of the jet core and the yarn in the jet core always generates non-uniform vibration, thereby causing loop unevenness and confounding unevenness.
In particular, there was a problem that high-speed processing at 600 m / min or more could not be performed.

The cleaning cycle of the compressed fluid processing nozzle is longer than before, so that the productivity is improved and the quality of the yarn is stabilized. Further, since the yarn cleaning member is provided in contact with the yarn guiding hole path portion of the jet core so as to reach near the air injection hole, vibration is not generated in the yarn in the jet core. Thus, stable machining is performed and high-speed machining is performed.

A feed roller (relax roller) 29 for sending the yarn (fluid processed yarn) Y to a take-up roller (not shown) is provided below and to the left of the compressed fluid processing nozzle 3.

With the above configuration, for example, water as a liquid is discharged from a fluid supply source (not shown) by a pump, and
Is heated to, for example, 35 to 45 ° C. by a heating means provided in the middle of the process, and is sent from the pipe 15 to the watering nozzle 9. The heated water is applied to the core filament yarn C by the watering nozzle 9.

Compressed air is discharged from a compressed air supply source (not shown), and is supplied through a pipe 23 to the compressed fluid processing nozzle 3.
After being sent from the compressed air supply port 21 to the compressed fluid chamber 19, the compressed air is supplied from the air injection hole 17 into the jet core 7, and the core filament yarn C and the sheath filament yarn E are subjected to the compressed fluid treatment to increase the bulkiness. Yarn Y is obtained.

Accordingly, the core filament yarn C and the sheath filament yarn E are pulled out from a supply package (not shown), respectively, and sent out by the supply rollers 25 and 27. The core filament yarn C sent out by the supply roller 25 is sent to the jet core 7 of the compressed fluid processing nozzle 3 via the yarn guide 11.

On the other hand, the sheath filament yarn E is
7 and is sent to the jet core 7 of the compressed fluid processing nozzle 3 through the yarn guide 13. The core filament yarn C and the sheath filament yarn E sent to the jet core 7 are subjected to a compression fluid treatment to obtain a bulky yarn Y having loops, entanglements, and slacks uniformly in the longitudinal direction. It is taken up by a take-up roller (not shown) via a relax roller 29.

A gear 31 is fitted around the outer periphery of the protrusion (flange) 7T of the jet core 7, and another gear 33 is meshed with the gear 31. An output shaft 37 of a drive motor 35 fixed on a gear box is mounted on the gear 33, for example.

With the above configuration, when the drive motor 35 is driven, the gear 33 is rotated via the output shaft 37, and the jet core 7 is rotated with respect to the nozzle housing 5 via the gear 31. Become.

As shown in FIGS. 2A and 2B, the yarn guiding hole path portion 7A of the jet core 7 reaches the vicinity of the air injection hole 17 and serves as a yarn cleaning member. A wire 39 which is a linear member is provided in contact with the yarn introduction path portion 7A, and is provided at one end of the wire 39 so as to be detachably attached to a fixing member (not shown).

With the above configuration, when compressed air is sent from the compressed air supply port 21 to the compressed fluid chamber 19 through the pipe 23,

And bulky yarn Y such as entanglement and sagging can be obtained.

When the core filament yarn C and the sheath filament yarn E are supplied into the jet core 7 and the bulky yarn Y is obtained by the compressed fluid, the jet core 7 rotates as shown in FIG. 2 (B), the core filament yarn C, the sheath filament yarn E and the wire 39 are fixedly traveling in the yarn introduction path 7A of the jet core 7 at a certain place. Instead, the jet core 7 is always in contact with and running along the inner circumference of the yarn introduction path 7A of the jet core 7.

Accordingly, dirt such as the raw filament oligomer of the core filament yarn C and the sheath filament yarn E tends to adhere to the yarn introduction hole path portion 7A of the jet core 7, but the rotation of the jet core 7 causes the core filament yarn C, The sheath filament yarn E and the wire 39 are not always fixed at a fixed position of the jet core 7, and the yarn introduction hole path portion 7A of the jet core 7
Is moved along the circumference of the jet core 9 even if the dirt adheres to the inner wall of the jet core 9. The dirt can be removed when the sheath filament yarn E and the wire 39 pass again. Thus, since dirt does not adhere to the yarn introduction hole path portion 7A of the jet core 7, the cleaning cycle of the compressed fluid processing nozzle 3 can be made longer than before, so that productivity can be improved. . In addition, since the stain does not adhere to the yarn introduction hole path portion 7A of the jet core 7, the fluctuation of the running tension of the core filament yarn C and the sheath filament yarn E becomes smaller than before, so that stable processing can be obtained. Good bulky yarn with stable quality can be obtained. In addition, since the wire 39 other than the core filament yarn C and the sheath filament yarn E is positively brought into contact with the yarn introduction hole path portion 7A of the jet core 7, the core filament yarn C and the sheath filament yarn E
The dirt (adhered matter) that cannot be completely removed by the contact of the toner can be easily cleaned.

Further, since the wire 39 is provided in contact with the yarn introduction path 7A of the jet core 7 so as to reach near the air injection hole 17, the compressed air injected from the air injection hole 17 flows backward. You won't have to. As a result, the vibration of the core filament yarn C and the sheath filament yarn E is reduced as compared with the conventional case, so that stable processing can be performed, and high-speed processing of, for example, 600 m / min or more can be performed.

FIG. 3 shows another air processing machine 1 instead of FIG. In FIG. 4, the same components as those in FIG. 1 are denoted by the same reference numerals, and redundant description will be omitted. In FIG. 4, a nozzle housing 5 is rotatably mounted on a bracket 41 fixed to, for example, a gear box (not shown). The bracket 41 is provided with another compressed air supply port 43 communicating with the compression supply port 21.

With the above configuration, when compressed air is sent from the pipe 45 to the compressed fluid chamber 19 through the compressed air supply ports 45 and 21, the compressed air is injected from the plurality of air injection holes 17 into the jet core 7 and jetted. Compressed fluid treatment is performed on the core filament yarn C and the sheath filament yarn E supplied into the core 7, so that a bulky yarn Y having a uniform loop in the longitudinal direction, entanglement, sagging, and the like can be obtained.

When the nozzle housing 5 is rotated,
The jet core 7 is also rotated in the same direction. Further, since a wire 39 as a yarn cleaning member is provided in the yarn introduction hole path portion 7A of the jet core 7 as shown in FIG. 1, detailed description is omitted, but it is described in FIG. It has the same function and effect as described above.

As shown in FIG. 4A, instead of the wire 39, a half-split arc member 63 is used as the yarn cleaning member, and the jet core 7 is covered with the sheath filament yarn E. May be used by being provided in contact with the yarn introduction hole path portion 7A. Further, as shown in FIG. 4 (B), the half-split arc member 63 is brought into contact with the introduction hole path portion 7A of the jet core 7 while covering both the core filament yarn C and the sheath filament yarn E. It may be used by providing it at least. In this case, the jet core 7 or the nozzle housing 5 may be rotated only by reciprocating at the angle indicated by the arrow in FIG. 5B.

The material of the wire 39 or the half-arc member 63, which is a rod-like material as the thread cleaning member, may be any material as long as it is a metal or material softer than ceramic. The diameters of the wire 39 and the half-arc shaped member 63 are appropriately determined according to the diameter of the jet core 7.

The rotation of the jet core 7 or the nozzle housing 5 is not limited to rotation in one direction, but may be rotation in another direction. Further, normal rotation may be performed. The jet core 7 or the nozzle housing 5 may not be continuously rotated in one direction or the other direction, but may be reciprocated using a rack and a pinion. The rotation or reciprocating rotation of the jet core 7 or the nozzle housing 5 may be temporarily stopped and intermittently rotated or rotated instead of being continuously performed. The point is that the jet core 7 or the nozzle housing 5 is not fixed but rotated by any means.

The compressed fluid processing was performed by the air processing machine 1 shown in FIG. 1 or FIG. 4 under the condition of overfeed + 35%, the jet core 7 or the nozzle housing 5 for one rotation of 27 seconds.

As a result, the conventional nozzle cleaning time is changed from one day to
What was performed once every 1.5 days, but in this embodiment, from 4 days to
We only need to change once every five days. That is, the cleaning time of the compressed fluid processing nozzle 3 that is three to four times as long as that in the related art can be delayed. Therefore, the productivity was able to be greatly improved compared with the conventional case. In addition, the stability of processing and the stability of yarn quality were almost the same as those of the prior art, and uniform bulky yarn was obtained. Further, the vibration of the core filament yarn C and the sheath filament yarn E in the jet core 7 is reduced as compared with the conventional one, so that stable processing can be performed, and high-speed processing of 600 m / min or more is possible.
