2. Description of the Related Art Conventionally, a device for obtaining a fiber sheet by entanglement of fibers by applying a fluid flow such as a high-pressure water flow to a fiber web has been known. Because of the action, vertical streaks due to the fluid flow were conspicuous in the direction of flow of the conveyor, and a fiber sheet that was favorable in appearance could not be obtained.

In the nozzle device for entanglement treatment of the present invention, a plurality of rows of fluid injection holes having the same hole diameter are arranged, and adjacent fluid injection hole rows have different hole diameters. It is in a position where it cannot be. Therefore, even a portion that cannot be entangled by the fluid flow of the fluid ejection hole array in the front row can be entangled by the fluid flow of the fluid injection hole array in the rear row, so that the entanglement processing can be performed over the entire fiber web. Further, the diameters of the adjacent fluid ejection hole rows are different, and in particular, the ratio of the fluid ejection hole diameter to the rear row of the front row satisfies the relationship of 0.7 to 0.9 or the relationship of 1.1 to 1.4. When there is a row of adjacent fluid ejection holes that fills, the fluid flow ejected from the fluid ejection hole row in the rear row is the same as the fluid flow ejected from the fluid ejection hole row in the front row. Since the impacts of the fluids are different, there is a difference in the time that the fluid flow ejected from each fluid ejection hole array acts on the fiber web, but it is possible to obtain a fiber sheet in which the vertical stripes are inconspicuous as a whole. I found it.

In the case of two rows of fluid ejection holes of this entanglement treatment nozzle device as shown in FIGS. 1 (a) and 1 (b), the fluid in the first row with respect to the flow direction of the fibrous web. Since the fluid ejection hole arrays 2 of the second row do not overlap with each other, preferably at an intermediate position between the fluid ejection holes of the first row, between the ejection hole rows 1, the entire fibrous web is covered. Entanglement processing can be performed. In the case of three rows as shown in FIGS. 2A and 2B, the second fluid ejection hole row 2 is positioned so as not to overlap the first fluid ejection hole row 1, Furthermore, the third fluid ejection hole array 3 may be positioned so as not to overlap between the second fluid ejection hole array 2. In this case, the third fluid ejecting hole array 3 may be located at a position overlapping the first fluid ejecting hole array 1, but it is more preferred that the third fluid ejecting hole array 3 is not located so that the vertical stripes are not conspicuous.

It is preferable that the same relationship as above holds even in the case of four or more rows of holes.

The diameter of the fluid injection holes in the same row is
It is designed to have the same hole diameter so that the entanglement action by the fluid flow in the same row acts in the same way. If the diameter of the fluid injection hole is smaller than 0.05 mm, the energy of the injected fluid flow will be small, and the confounding process cannot be performed efficiently. On the other hand, if it is larger than 0.2 mm, the fibers will become entangled. Since it is difficult, 0.05 to 0.2 mm is suitable, and more preferably 0.08 to 0.15 mm.

Further, since the diameters of the adjacent fluid ejection hole rows are not the same but different, fluid streams having different states such as the width of the fluid flow, the amount of fluid, the position of the fluid, and the impact due to the fluid can be obtained in each row. Therefore, it becomes possible to obtain a fiber sheet in which vertical streaks are inconspicuous. Particularly, in the case of two rows as shown in FIGS. 1A and 1B, the fluid injection hole diameter (d 1 ) of the first row is 2
A remarkable effect can be obtained when the ratio (d 1 / d 2 ) to the fluid ejection hole diameter (d 2 ) in the row is 0.7 to 0.9 or 1.1 to 1.4. This fluid injection hole diameter ratio (d 1 / d 2 ) is 0.
If it is less than 7, vertical streaks due to the fluid flow in the second row are conspicuous,
When it exceeds 1.4, the vertical streaks due to the fluid flow in the first row are conspicuous,
Further, if it is 0.9 to 1.1, the vertical streaks due to the fluid flow are conspicuous. This fluid injection hole diameter ratio (d 1 / d 2 )
Is 0.7 to 0.9 and 1.1 to 1.4 in some cases because the fluid flow in the first row is weaker than the fluid flow in the second row due to the fiber web to be entangled. Is preferable, and it may be preferable that the fluid flow in the first row is stronger than the fluid flow in the second row. In the former case, the fibrous webs are not entangled or the degree of entanglement is low, and if the fluid flow in the first row is made stronger than the fluid flow in the second row, the entanglement action is too strong. Because it is easy for vertical streaks and unevenness,
In the latter case, the degree of entanglement of the fibrous web is high, and if the fluid flow in the second row is made to act more strongly than the fluid flow in the first row, the vertical streaks are easily noticeable.

In the case where there are three rows of fluid ejection hole arrays as shown in FIGS. 2A and 2B, similarly, the fluid ejection hole diameter of the second row of the fluid ejection hole diameter (d 1 ) of the first row is the same. (d 2) the ratio (d 1 / d 2) is 0.7 to 0.9 or 1.1 to 1.4, the third column of fluid jet in the second column of fluid ejection hole diameter (d 2) pore size ratio (d 3) (d 2 / d 3) is preferably a 0.7 to 0.9 or 1.1 to 1.4. The ratio for the three row of fluid ejection hole diameter of the first column of fluid ejection hole diameter (d 1) (d 3) (d 1 / d 3) need not satisfy the above relationship. Even when the number of rows of fluid ejection holes is four or more, the same effect can be obtained if the same relationship as above holds.

Further, the distance between the fluid injection hole rows is 0.5 mm.
If it is less than 2, the adjacent fluid flows interfere with each other, while if it exceeds 2 mm, the time difference between the entanglement treatment by the fluid flows in the front row and the back row becomes too large and the vertical streaks stand out, so it is 0.5 mm to 2 mm. Is preferred. More preferably, it is 0.5 to 1 mm. The inter-row distance of the fluid ejection hole row is the distance between the straight line passing through the center of the fluid ejection hole in the front row and the straight line passing through the center of the fluid ejection hole in the rear row.

As described above, the entanglement treatment nozzle device of the present invention, in which a plurality of fluid injection hole arrays are arranged, may be applied to the fiber web not only once but twice or more. . In this case, the diameter of the fluid ejection holes in the first row at the time of the first treatment is reduced so that vertical streaks and wrinkles are less likely to occur,
It is more preferable to reduce the diameter of the fluid injection hole in the last row of the last time so that vertical streaks and wrinkles are less likely to occur.
