The yarn path 22 is provided with an injection hole 25 for discharging a compressed fluid. The yarn M enters the entrance 23 of the yarn path 22 and the exit 24 of the yarn path 22. By injecting the compressed fluid from the injection holes 25 in a more protruded state, the yarn M traveling in the yarn path 22 is entangled.

ことが難しいものであった。By the way, in order to impart confounding to the yarn M, the yarn M running in the yarn path 22 can be sufficiently vibrated by the action of the compressed fluid ejected from the injection holes 25. In such a state, that is, it is necessary to keep the yarn tension sufficiently low. In the yarn entanglement processing apparatus shown in FIGS. 5 to 8, the yarn tension of the yarn M entering the entrance 23 and the exit 24 No consideration was given to the relationship between the yarn M and the yarn tension of the yarn M run from the yarn, and it was difficult to stably impart confounding.

ることができず、交絡加工が不安定であった。That is, according to the study of the present inventor, the yarn M
In order to stably impart entanglement to the yarn, the yarn M running on the yarn path 22 must have a sufficiently low thread tension,
It has been found that it is necessary to make the yarn tension running into the yarn and the yarn tension running out from the yarn path 22 equal or approximate, but the conventional yarn shown in FIGS. In the entanglement processing device 30, the cross-sectional area of the run-in port 23 of the yarn path 22 is equal to the cross-sectional area of the run-out port 24, and the compressed fluid ejected from the injection hole 25 moves the yarn M at the center of the yarn path 22. Since the jet is ejected at right angles to the direction, the flow rate discharged from the run-in port 23 of the yarn path 22 is equal to the flow rate discharged from the run-out port 24 of the yarn path 22, but the yarn traveling on the yarn path 22 M has a running resistance due to sliding with the inner wall of the yarn path 22 due to the compressed fluid ejected from the injection hole 25, so that the yarn tension of the yarn M entering the entrance 23 is low, and The yarn M running from the outlet 24 has a higher yarn tension, and It is impossible to approximate the yarn tension of the preparative run outlet 24 side, intermingling process was unstable.

定となり、交絡に悪影響を及ぼす恐れがあった。Therefore, in order to lower the increased yarn tension on the run-out port 24 side, the running speed of the yarn M on the run-in port 23 side must be increased or the running speed of the yarn M on the run-out port 24 side must be increased. However, under such high overfeed processing conditions, the yarn tension of the yarn M entering the entrance 23 at the same time becomes extremely low, and the yarn M on the entrance 23 side has excessive yarn tension. Looseness occurs, running of the yarn M becomes unstable, and there is a possibility that the confounding may be adversely affected.

して交絡を付与することができなかった。On the other hand, in the yarn entanglement processing device 30 shown in FIGS. 6 to 8, the discharge flow rate at the run-out port 24 side due to the compressed fluid ejected from the injection holes 25 can be made larger than the discharge flow rate at the run-in port 23 side. Therefore, although the occurrence of excessive slack of the yarn M at the entrance 23 can be reduced, the yarn tension at the exit 24 is looser (smaller) than the yarn tension at the entrance 23, so that the yarn M is unbalanced. In this state, a phenomenon in which the yarn M running in the yarn path 22 moves at once in a lump state by the propulsion effect of the compressed fluid ejected from the injection hole 25, that is, a so-called jumping phenomenon occurs. It was easy to occur, and this suddenly moved portion resulted in lack of confounding, and confounding could not be stably provided.

いなかった。In particular, in recent years, the variety and characteristics of the yarn M have been diversified, and confounding conditions have to be individually set accordingly. In addition, the processing speed of the yarn M has been increased, and accordingly, the chances of performing the entanglement processing under the processing conditions of high overfeed have increased. For this reason, it is required that stable entanglement can be obtained by changing the injection pressure with respect to various types, characteristics, and processing conditions of various yarns M. No material capable of imparting stable confounding to M has been obtained.

ある。The object of the present invention is to provide a variety of yarn types, characteristics and processing conditions of 0.1 to 0.4 MPa.
Within the range of the injection pressure, a stable entanglement process can be performed without causing a jumping phenomenon even when the injection pressure is varied, and the flow rate of the compressed fluid is reduced, and the yarn is less damaged. It is to provide a confounding processing device.

与することができる。To impart confounding to the yarn M by the yarn confounding processing device 10, the yarn M is run on the yarn path 2 and an injection pressure of 0.1 to 0.4 MPa is applied to the injection hole 5. While supplying the compressed fluid, the traveling speed of the yarn M on the entrance 3 side is adjusted, and the yarn tension of the yarn M entering the entrance 3 is set to 0.5 to 5 g. Since the difference between the yarn tension of the yarn M entering the yarn and the yarn tension of the yarn M exiting from the exit 4 can be set to 4 g or less, preferably 3.5 g or less, and more preferably 3 g or less, jumping is performed. Stable entanglement can be provided with little flow of the compressed fluid without causing a phenomenon or the like and without damaging the yarn M.

との差を４ｇ以下に近似させることができる。That is, in the yarn entanglement processing device 10 shown in FIGS. 1A and 1B, the cross-sectional area (Sout) of the run-out port 4 is made larger than the cross-sectional area (Sin) of the run-in port 3 and the injection hole 5 is formed. Since it is inclined and its opening is directed to the runway 4 side, the discharge flow rate (Qout) from the runway port 4 can be made larger than the discharge flow rate (Qin) from the runway port 3.
The excessive slack of the yarn M on the side can be prevented, and the yarn tension at which the yarn M enters the entrance 3 is 0.5 to 5 g.
Therefore, the yarn M traveling in the yarn path 2 has a small yarn tension and has an appropriate bending, so that the yarn M is vibrated in the yarn path 2 by the action of the compressed fluid ejected from the injection hole 5. Can be done. And run entrance 3 and run exit 4
The ratio of the discharge flow rate of the outlet 3 to the sum of the discharge flow rates of the entrance 3 and the exit 4 is 25 to 45% with respect to the sum (Qin + Qout) of the discharge flow of the intake port 55 to 55%. 75%, and the relationship between the yarn tension on the run-out port 4 side and the yarn tension on the run-in port 3 side depends on the relationship between the yarn tension (0.5 to 5 g) at which the preset yarn M enters the run entrance 3. The difference can be approximated to 4 g or less.

にすれば良い。Here, the reason why the yarn tension at which the yarn M enters the entrance 3 is 0.5 to 5 g is that if the yarn tension is less than 0.5 g, the yarn tension of the yarn M is too low. In this state, the running of the yarn M on the side of the entrance 3 becomes unstable, and the entanglement is lost. Conversely, when the yarn tension exceeds 5 g, the yarn traveling in the yarn path 2 Because the yarn tension of the yarn M becomes too large, a large vibrational motion of the yarn M in the yarn path 2 cannot be obtained, and the confounding processing becomes unstable. In addition,
In order to set the yarn tension at which the yarn M enters the entrance 3 to 0.5 to 5 g, the traveling speed of the yarn M entering the entrance 3 or the traveling speed of the yarn M exiting from the exit 4 May be adjusted so that, for example, the value of the tension meter becomes 0.5 to 5 g.

の調整ができなくなるからである。The ratio of the discharge flow rate of the entrance 3 to the total (Qin + Qout) of the discharge flow rates of the entrance 3 and the exit 4 is less than 25% (to the total (Qin + Qout) of the discharge flow rates of the entrance 3 and the exit 4). If the discharge flow rate of the run-out 4 exceeds 75%), the effect of pushing out the yarn M becomes excessive and a jumping phenomenon occurs, and conversely, the discharge of the run-in 3 and the run-out 4 Sum of flow rate (Qin
+ Qout) is 45%
Exceeds the sum (Qin
+ Qout) is 55%
This is because the effect of pushing out the yarn M is small, and the adjustment of the yarn tension becomes impossible.

The ratio of the discharge flow rate of the entrance 3 to the sum of the discharge flow rates (Qin + Qout) is 30 to 40%, and the ratio of the discharge flow rate of the exit port 4 to the sum (Qin + Qout) of the discharge flow rates of the entrance 3 and the exit 4 is It is good to be 60 to 70%.
