Description of the Related Art In order to impart effective entanglement to a yarn using the above-mentioned entanglement processing nozzle and to impart reproducible and stable convergence or bulkiness, it is necessary to perform yarn treatment from an injection nozzle. The delicate state of the gas flow ejected to the cylinder has a great effect. If the gas flow condition is not appropriate, even if there is a slight difference, satisfactory entanglement processing cannot be performed, or the yarn gets stuck in the yarn insertion port or jumps out from the yarn insertion port, making it impossible to operate. . For this reason, various devices have been added to the positions of the injection nozzle and the yarn insertion port. JP-A-58-6

FIG. 1 is a schematic cross-sectional view showing a preferable example of a yarn entanglement processing nozzle of the present invention in which the cross-sectional shape of the yarn processing cylinder 1 is a circle. FIG. 2 is a sectional view taken along line AA ′ of FIG. In the present invention, the center of gravity axis of the yarn processing cylinder 1 refers to a cylinder axis passing through the center of gravity P of each cross section with respect to the axial direction of the yarn processing cylinder 1. The yarn entanglement processing nozzle of the present invention performs entanglement processing by running the yarn in the cylinder axis direction a in the yarn processing cylinder 1. The entanglement processing nozzle is normally used by being joined to a flow path member (not shown) having a flow path for supplying pressurized gas to the injection nozzles 2 and 2 ′. In order to blow gas into the yarn processing cylinder 1, the yarn processing cylinder 1 is provided with openings 3 and 3 ′ of two opposing injection nozzles 2 facing each other. These two injection nozzles 2 and 2 ′ are axes passing through the respective centers of gravity P (in the case of a cross-sectional shape of a circle, coincide with the center) of a plurality of arbitrary cross-sections of the yarn processing cylinder 1, A straight line b perpendicular to the axis of the cylinder center of gravity is arranged as a common central axis.

Can be For convenience of explanation, the slit gap of the yarn insertion port 4 is indicated by G.
In the present invention, the position where the yarn insertion port 4 is provided is important. First of all, the openings 3, 3 'must not overlap. Then, a plane (c, c ′) separated by G / 2 from both sides of the plane q passing through the center of gravity P within a range of G / 2 from the plane q passing through the center of gravity P and orthogonal to the straight line b. It must not be inside. Thread insertion opening 4 and openings 3, 3 '
By avoiding the overlap, that is, by separating the positions of the two, excellent entanglement can be imparted to the yarn with good reproducibility and stability. The reason is that in the entanglement processing nozzle (see FIG. 4) which has been widely used, the fluid injected from the injection nozzle 42 toward the inside of the yarn processing cylinder 41 is disturbed by the presence of the yarn insertion port 44. Is considered to be the cause. Further, when the yarn is provided outside the range of G / 2 from the plane passing through the center of gravity P and orthogonal to the straight line b, the yarn may fly out of the yarn processing cylinder 1 or be caught in the yarn insertion port 4 within the range. Because it is easy to do. The reason is that the opposing injection nozzle 2
It is considered that the fluid ejected from the nozzle collides at the center of gravity P and its vicinity, flows along the inside or near the surfaces c and c ', and the yarn is swept away by the flow. on the other hand,
The slit-shaped thread insertion path 5 communicating with the thread insertion port 4 does not need to be provided so that the center plane passes through the center of gravity of the cylinder.

が得られる。In manufacturing the yarn entanglement nozzle of the present invention, the cross section of the yarn processing cylinder 1 is particularly preferably a circle or a missing circle. In the case of a circle, the center of gravity P of the cross section of the yarn processing cylinder 1 coincides with the center of the circle. In the present invention, the missing circle means a closed region in which a chord is an arc of 180 degrees or more and a straight line orthogonal to a straight line passing through the center of the arc. FIG. 3 shows an example in the case of a missing circle. In this case, the center axis of the injection nozzle 32 is located on the symmetric center line b3 of the cross section of the yarn processing cylinder 31. The yarn insertion port 34 is provided at the opening 3 of the injection nozzle 32.
3 and is outside the range of G / 2 from a plane passing through the center P3 of the original circle of the missing circle of the cross-sectional shape of the yarn processing cylinder 31 and orthogonal to the straight line b3, thereby providing high entanglement. Performance is obtained.
