(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a fancy yarn processed by the nozzle of the present invention, FIG. 2 is a schematic perspective view illustrating a part of the process, FIG. 3 is a vertical sectional view of a nozzle assembly of the present invention, and FIG. It is an enlarged sectional view around a throttle hole and a ventilation hole.

The nozzle 3 for producing the fancy yarns 1 and 2 by the pressure fluid has a gas introduction hole 6 communicating with the gas chamber hole 5 in the cylinder on the side surface of the cylinder body 4 and a screw threaded on the edge of the body part. Part 7
Is provided, and is threadedly engaged with the threaded portion and a stopper 7'for adjusting the setting of an inner 9 described later, and threadedly engaged with the threaded portion 7, and is fitted into the gas chamber hole, and a thread guide hole 8 is formed at the center. Inner 9 to set
And the ejection hole 10 fitted into the gas chamber hole 5 on the outlet side of the thread guiding hole.
And a baffle plate 12 attached to the outlet side of the ejection hole. A venturi-shaped throttle hole 13 is provided in the middle of the thread guide hole 8, and the vent hole 11 is provided on the outlet side of the thread guide hole 8. A ventilation hole 14 that is inclined toward and communicates with the throttle hole 13 is formed,
The inclination angle θ of the ventilation hole is preferably about 15 °, and the diameter of the tip portion of the ventilation hole 14, that is, the restriction hole 13 side is narrowed by giving a restriction, and the direction of the center line is slightly smaller than the center line of the restriction hole 13. The size may be such that it can be removed, that is, about a processing error, and a swirling flow in the throttle hole 13 described later is generated by the size.

The venturi 11 for forming the ejection hole 10 is fitted in the cylinder of the body portion 4 by shifting the center of the ejection hole and the center line of the thread guide hole 8 by about 0.5 to 0.7 mm. 11
It is sufficient to superimpose the screw hole formed on the collar portion of the body and the screw hole formed on the end face of the body portion 4 and tighten the set bolt 15 to form the ejection hole.
A baffle plate 12 having an opening 16 on the outlet side of 10 is fixed to the body 4.

The venturi 11 and the outlet of the thread guide hole 8, that is, the tip of the inner 9 forms an eccentric annular path portion 17, but the gap can be adjusted by tightening the inner 9 in any way. The amount of pressure fluid injected from 14 is adjusted.

The gas introduction hole 6 is connected to, for example, a compressed air source by a hose (not shown), and when high-pressure air is injected, it becomes a nozzle 3 for processing the fancy yarns 1 and 2, and a strand 18 is inserted into the inlet of the thread guide hole 8 to generate the high pressure. The fancy yarn is discharged from the opening 16 between the venturi 11 and the baffle plate 12 by the action of air.

As an accessory to the nozzle 3 , rolls 19 and 20 for supplying the strands 18 are arranged at the inlet side of the yarn guide hole 8. When a single strand 18 is supplied at the same speed as the rolls, as shown in FIG. As shown, it is possible to manufacture a fancy yarn 1 in which bulky parts 21 and entangled parts 22 are alternately arranged and one or two loop-shaped twisted balls 23 are attached to the entangled parts in a random direction. .

Hereinafter, the operation of the nozzle 3 in the present invention will be described.

The single strand 18 which is sandwiched between the supply rolls 19 and 20 arranged on the inlet side of the yarn introducing hole 8 and is supplied to the yarn introducing hole is supplied by the high pressure air injected from the gas introducing hole 6 to the gas chamber hole 5. It is discharged from the opening 16 together with air, and part of the air is a vent hole.
A high-speed spiral turn is made in the throttle hole 13 via the thread guide hole 8
The remaining air is discharged from the outlet of the ventilator, passes through the passage 17 from the gas chamber hole 5, diffuses turbulently from the ejection hole 10 of the venturi 11, collides with the baffle plate 12 and is discharged from the opening 16. The swirling flow in the throttle hole 13 imparts S or Z twist to the strand 18 at the injection point of the ventilation hole 14, and when the twist moves to the exit side of the yarn guide hole 8, the S or Z is applied after the injection point. The Z twist is untwisted by false twisting with false twist, and the high-pressure air passing through the throttle hole 13 acts on the untwisted strand 18 to move to the entanglement route portion 17, which is the route. Due to the eccentric annulus of the part, a swirling flow slower than the swirling is generated also in this part, and from the difference between the number of rotations of the strand 18 in the yarn introducing hole 8 and the number of rotations of different strands 18 in the route part 17, The resulting loop-shaped bump, or twist ball 23, And, due to the repeated phenomenon of untwisting and entanglement due to the movement of the strand, the bulky portion 21, the entangled portion 22, and the loop-shaped twisted ball 23 are formed, but the twisted ball twists in the path portion 17. A new entanglement is also generated at the base of the twisted ball 23 due to the diffused turbulent flow of the air flow discharged from the ejection hole 10 without returning it, and the entanglement causes the entanglement to discharge from the opening 16 while maintaining a loop shape.

In the nozzle 3 in which the inner diameter of the thread guiding hole 8 is 3 mmφ, the inner diameter of the throttle hole 13 is 2 mmφ, and the ejection port diameter of the vent hole 14 is 1.5 mmφ, 3
150m / at 300 tex using high pressure air up to 4 atmospheres
It is possible to secure a production rate of 120 m / min for 500 tex and 90 m / min for 1000 tex, and the pitch between the twisted ball 23, the entangled portion 22 and the bulky portion 21 formed alternately is 3 to 10 mm. 20
The fancy yarn 1 has a high fluffability of up to 60 mm and a small amount of fluff and a very small elongation, and it is possible to provide a fabric having a ground pattern in textile processing and having a good interior property.

If the strands 18 of Tweweed are combined with different materials, for example, if one strand is aramid fiber and the other strand is glass fiber, or glass fiber and carbon fiber, the characteristics of both are utilized, and its application is further expanded. It is a thing.

(Effects of the Invention) From the nozzle of the present invention, it is possible to form a novel bulky system that is rich in fashionability and interior properties and has very little fuzz and elongation due to the swirling flow in two places, and as a cloth for high-end products. Its utility is remarkable, such as the fact that it can be woven.
