付与するようになっている。This yarn entanglement treatment device 30 has a block body 2 having a through hole having a circular cross-section as the yarn path 22.
1, the yarn path 22 is provided with an injection hole 25 for ejecting a compressed fluid, and the yarn M is introduced into the run-in port 23 of the yarn path 22 and the run-out port 24 of the yarn path 22. The compressed fluid is ejected from the ejection holes 25 in a state where the yarn M is running further, so that the yarn M running 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 the entanglement 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 ejection holes 25. Although it is necessary to keep such a state, that is, the state in which the yarn tension is sufficiently loose, in the yarn confounding processing device shown in FIGS. Since no consideration was given to the relationship with the yarn tension of the yarn M run from the fiber, it was difficult to stably provide the entanglement.

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 by the present inventor, the yarn M
In order to stably apply the entanglement to the yarn, the yarn tension of the yarn M traveling in the yarn passage 22 is, of course, sufficiently low.
It has been found that it is necessary to equalize or approximate the yarn tension that runs into the yarn and the yarn tension that runs from the yarn path 22. However, the conventional yarn shown in FIGS. In the entanglement treatment device 30, the cross-sectional area of the run-in port 23 of the yarn path 22 and the cross-sectional area of the run-out port 24 are equal, and the compressed fluid ejected from the injection hole 25 runs the yarn M at the center of the yarn path 22. Since it is jetted at a right angle to the direction, the flow rate discharged from the running port 23 of the yarn path 22 and the flow rate discharged from the running port 24 of the yarn path 22 are equal, but the yarn running in the yarn path 22 Since a running resistance is exerted on M by sliding on the inner wall of the yarn path 22 by the compressed fluid jetted from the jet holes 25, the yarn tension of the yarn M entering the runner port 23 is gentle, The thread tension of the yarn M run from the exit 24 becomes high, and the runway 23 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 reduce the yarn tension on the side of the running outlet 24, which is increased, the running speed of the yarn M on the running port 23 side is increased, or the running speed of the yarn M on the running port 24 side is increased. However, under such high overfeed processing conditions, the yarn tension of the yarn M that enters the runner port 23 at the same time becomes extremely low, and the yarn M on the runner port 23 side becomes excessive. There is a possibility that loosening may occur, the running of the yarn M may become unstable, and entanglement 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 treatment device 30 shown in FIGS. 6 to 8, the discharge flow rate of the compressed fluid ejected from the injection holes 25 on the side of the running port 24 can be made larger than the discharge flow rate on the side of the running port 23. Therefore, although it is possible to reduce the occurrence of excessive slack in the yarn M on the runner entrance 23 side, the thread tension on the runner exit 24 side is looser (smaller) than the thread tension on the runner entrance 23 side and is unbalanced. In this state, a so-called jumping phenomenon occurs in which the yarn M running in the yarn path 22 moves at once in a lump state due to the propelling effect of the compressed fluid ejected from the ejection holes 25. The entanglement is likely to occur, and the entanglement cannot be stably applied because the entanglement is lost at the locations where the entanglement is performed all at once.

いなかった。In recent years, in particular, the types and characteristics of the yarn M have been diversified, and the entanglement processing conditions have to be individually set accordingly. In addition, the processing speed of the yarn M is also increasing, and accordingly, the chances of performing the entanglement treatment under the high overfeed processing conditions are increasing. Therefore, it is required that stable entanglement can be obtained by varying the injection pressure with respect to various types, characteristics, and processing conditions of various yarns M. However, one yarn entanglement processing device can be used for various yarns. No material capable of imparting a stable entanglement to M has been obtained.

Within the range of the injection pressure, stable entangling processing is possible without causing a jumping phenomenon even if the injection pressure is changed, and the flow rate consumption of the compressed fluid is small and the yarn is not damaged.

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 treatment device 10 of FIGS. 1 (a) and 1 (b), the cross-sectional area (Sout) of the running outlet 4 is made larger than the cross-sectional area (Sin) of the running inlet 3 and the injection hole 5 is formed. Since the opening is inclined and the opening is directed toward the running outlet 4, the discharge flow rate (Qout) from the running exit 4 can be made larger than the discharge flow rate (Qin) from the running entrance 3,
It is possible to prevent the occurrence of excessive looseness of the yarn M on the side, and to adjust the yarn tension of the yarn M entering the run-in port 3 to 0.5 to 5 g.
Therefore, since the yarn tension of the yarn M traveling in the yarn path 2 is small and has an appropriate bending, the yarn M vibrates in the yarn path 2 by the action of the compressed fluid ejected from the injection hole 5. Can be made. And runway 3 and runway 4
The ratio of the discharge flow rate of the runway 3 to the total discharge flow rate (Qin + Qout) of 25 to 45%, and the ratio of the discharge flow rate of the runway 4 to the total discharge flow rate of the runway 3 and the runway 4 (Qin + Qout) is 55 to 55%. The yarn tension of the yarn 4 on the side of the running port 4 and the yarn tension on the side of the running port 3 are set to 75% and due to the relationship with the yarn tension (0.5 to 5 g) at which the yarn M runs into the running port 3 in advance. The difference can be approximated to 4 g or less.

にすれば良い。The yarn tension at which the yarn M runs into the inlet 3 is set to 0.5 to 5 g. The yarn tension of the yarn M is too loose when the yarn tension is less than 0.5 g. This is because the running of the yarn M on the side of the run-in port 3 becomes unstable and a drop in the entanglement occurs. Conversely, when the yarn tension exceeds 5 g, the yarn running in the yarn path 2 is This is because the yarn tension of the yarn M becomes too large, so that a large vibration movement of the yarn M cannot be obtained in the yarn path 2, and the entanglement process becomes unstable. In addition,
The traveling speed of the yarn M entering the running inlet 3 or the traveling speed of the yarn M running through the running outlet 4 is set so that the yarn tension of the yarn M entering the running inlet 3 is 0.5 to 5 g. Is adjusted so that the value of the tension meter is 0.5 to 5 g, for example.

This is because, when the discharge flow rate of the running outlet 4 exceeds 75%, the propulsion effect of pushing out the yarn M becomes excessive and a jumping phenomenon occurs, and conversely, the discharging of the running inlet 3 and the running outlet 4 occurs.

条Ｍにダメージを与える恐れがあるからである。1 (a) and 1 (b) show an example in which a yarn guide is not provided in the vicinity of the running inlet 3 and the running outlet 4 of the yarn path 2, but in order to regulate the running of the yarn M. A thread guide may be provided in the vicinity of the running inlet 3 side and the running outlet 4 side of the yarn entanglement processing device. However, when providing a thread guide,
It is preferable that the thread guide on the runner entrance 3 side and the thread guide on the runner exit 4 side are installed at the same height, and the guide surface of each thread guide is within a region extending from the opening of the yarn path 2. . This is because if the heights of the yarn guides are different, the yarn M is bent on the guide surface and the running resistance increases, which may damage the running yarn M.
