(First embodiment)
An embodiment of the present invention will be illustrated and described with reference to reference numerals attached to elements in the drawing.
FIG. 1 is a plan view of a first embodiment of a ladder-like fabric according to the present invention.
In FIG. 1, a ladder-shaped fabric A is arranged in a bridging manner at appropriate intervals between two strip portions A ′ having a predetermined width and these left and right strip portions A ′, and an opening a is formed therebetween. And a crosslinked portion A ″.

FIG. 2 is an enlarged view showing a circled portion in FIG. 1 in order to explain the structure of the ladder-like fabric A.
Further, FIG. 3 is an enlarged view showing a main part of FIG.

The band portion A ′ is woven from the warp 1 and the weft 2.
The warp 1 and the weft 2 are filament yarns. For example, it is preferable to use a bundle of a plurality of filaments excellent in tensile strength such as polyester fibers.
Here, FIG. 4 is a sectional view taken along line IV-IV in FIG.
5 is a cross-sectional view taken along line VV in FIG.
As is apparent from FIGS. 4 and 5, the structure of the band portion A ′ is a structure woven into the warp yarn 1 in a state where two weft yarns 2 are fed together by a needle.
In the loom in which the weft yarns 2 are sent by the shuttle, it is possible to weave one warp yarn and one warp yarn.

6 is a cross-sectional view taken along line VI-VI in FIG.
In the bridging portion A ″, the wefts 2 of the band portion A ″ are squeezed by eight (four sets), and a hole (opening) a is formed therebetween.
7 is a cross-sectional view taken along line VII-VII in FIG.

3 and FIG. 7, the narrowing of the weft 2 is woven so as to be entangled with the four warp yarns 3 woven along the inside of the band portion A ′. Is performed.
Reference numerals 31, 32, 33, and 34 are attached to the drawing warp 3 in order from the innermost one.
Of the four warp yarns 3 for drawing, the middle two yarns 32 and 33 are woven into the weft yarn 2 so as to straddle eight (four sets) of weft yarns 2 as a unit.
In other words, after eight (four sets) of continuous wefts 2 have passed over (or below) the warp yarns 32, 33, the upper and lower sides of the warp yarns 32, 33 are recombined to form eight (four sets) of continuous warps. The weft 2 extends under (or above) the warp 3 for drawing.

Of the four warp yarns 3 for drawing, the two yarns 31 and 34 at both ends are woven into the weft yarn 2 so as to straddle four (two sets) of the weft yarns 2 as a unit.
In other words, after four (two sets) of continuous wefts 2 have passed over (or below) the warp yarns 31, 34, the upper and lower sides of the warp yarns 31, 34 are recombined to form four (two sets) of continuous warps. The weft 2 extends under (or above) the warp 3 for drawing.

The kite thread 4 is a leno weave with respect to these four warp threads 3 for drawing.
The kite thread 4 intersects the four warp threads 3 on the left and right, with eight (four sets) of wefts 2 as a unit.
Referring to FIG. 3, the kite yarn 4 runs on the right side of the four warp yarns 3 over the eight continuous weft yarns (four sets), and then passes through the back of the four warp yarns 3. Next, on the left side of the four warp yarns 3 for drawing, the yarn runs over the eight continuous weft yarns (four sets). By inserting the kite thread 4 in this way, the continuous eight (four sets) wefts 2 constituting the bridging portion are converged to widen the hole a in the vertical direction so that the hole a is sufficiently expanded. (The moving direction of the weft 2 is indicated by the white arrow in FIG. 3.) Also, the continuous four wefts 2 (four sets) are kept firmly by the kite thread 4, and the hole is not blocked. Like that. Furthermore, the warp yarn 4 prevents the four warp yarns 3 from shifting in the lateral direction.

The reed weave is used for restricting the lateral displacement of the four drawing warps 3.
By placing the kite thread 4 in a leno weave, the drawing warp thread 3 is laterally displaced and the hole is blocked.

The kite string 4 is preferably a monofilament.
The kite thread 4 has a role of binding the weft threads 2 so as to widen the hole. If the kite yarn 4 is the same filament yarn as the weft yarn 2, a large friction acts between them, and the weft yarn 2 does not move smoothly. Then, there arises a problem that the hole a does not sufficiently expand in the vertical direction. Filament yarns are flattened at the intersections and their mutual contact areas increase, and a large amount of friction occurs between them. This property is important for the fabric to maintain the structure, but considering the special role of the kite thread 4 to widen the holes in the ladder-like fabric, the weft thread 2 needs to slide easily with respect to the kite thread 4. is there.
Therefore, it is preferable that the kite yarn 4 is not a filament yarn but a monofilament so that a large friction does not work with the weft 2 which is a filament yarn.

  Furthermore, in order to reduce friction, it is preferable to make the cross-sectional shape of the kite string 4 circular so that the contact area is as small as possible.

Moreover, it is preferable that the diameter φ of the kite string 4 is about 0.25 mm.
This is 0.5 times or more that the diameter φ of the multifilament yarn is, for example, about 0.32 mm.
The kite thread 4 is required to have a strength for bundling the weft threads 2 so as to widen the hole and maintaining the weft threads 2 in a converged state.
Therefore, the kite string 4 is preferably a monofilament such as polyester and thick so as to have sufficient strength.
(By the way, simply using ordinary filament yarn does not provide the force to bundle a plurality of weft yarns 2)
The strength with which the continuous eight (four sets) wefts 2 can be kept firmly constrains the lower limit of the diameter of the kite yarn 4.

  However, since the kite thread 4 is woven by Leno weaving, the upper limit of the diameter of the kite thread 4 is regulated by the limit thickness that can be Leno weaved. In order to weave the kite thread 4 with Leno weave, the kite thread must be rolled (twisted) to the left and right while hanging in the air. If the monofilament becomes thicker, the strength of the loom will be stronger than that of the metal that makes up the loom. Therefore, the loom will be overwhelmed, and if the yarn (monofilament) is not sent well, the loom will be damaged. Empirically, it is impossible to reno weave monofilaments with a diameter of more than 1 mm.

There are a lower limit and an upper limit on the diameter of the kite thread 4 depending on two conditions, that is, the weft thread 2 has sufficient strength to be bundled and can be reno-woven.
Therefore, the kite string 4 is a monofilament such as polyester and preferably has a diameter of 0.1 mm to 1.0 mm, more preferably 0.2 mm to 0.7 mm, More preferably, it is 0.2 mm to 0.4 mm.

  With such a configuration, it is possible to obtain a ladder-like fabric that forms a sufficiently wide hole and further maintains the hole.

(Usage example of ladder-like fabric)
An example of using a ladder-like fabric will be briefly described.
Here, the structure which fixes the cloth sheet S, such as a tent, to the pole P using the attachment cloth T, the ladder-like fabric A, and the fastening tool B will be described.

  First, as shown in FIG. 8, the boss B2 of the fastening tool B is passed through the opening a near the one end of the ladder-shaped fabric A. Next, as shown in FIG. 9, the one end portion of the ladder-like fabric A is passed through the hole T ″ of the attachment fabric T, then bent, and further fixed to the opening a at the end of the ladder-like fabric A. The boss B2 of the tool B is passed through, and a fastening ring B3 is fitted and fixed to the boss B2.

  Next, the other side of the ladder-like fabric A is passed through the hole T ″ of the attachment fabric T (see FIG. 9), and then the ladder-like fabric A is folded back and overlapped on the outside of the one end and narrowed down. 10, the boss B2 of the fastening device B is inserted into the opening a at the other end of the ladder-shaped fabric A. Finally, the boss B2 is inserted into the boss B2 as shown in FIG. The other fastening ring B4 is fitted and fixed, and when the boss B2 is passed through the opening a of the ladder-shaped fabric A, the end of the ladder-shaped fabric A is folded back as shown in FIG. It is preferable from the viewpoint of binding strength.

(Modification 1)
As illustrated in FIG. 12, the kite thread 4 may be put on both sides of the four drawing warp threads 3.
The effect of restricting the lateral displacement of the drawing warp yarn 3 and the effect of converging the weft yarn are twice as large.
Further, if the string 4 is put on both sides of the drawing warp 3, the strength of one string 4 may be weakened.
In this case, the single kite string 4 is a monofilament such as polyester, and the diameter thereof may be about 0.15 mm to 0.25 mm.
It is a great merit to reduce the size of the kite thread 4 because it is a heavy burden on the loom to make the thick kite thread 4 reno weave.
However, the reno weaving increases, so the weaving work itself is slightly more complicated, but it is still very beneficial to reduce the load on the loom.

(Modification 2)
The holes a are not limited to a single row. For example, as shown in FIG. 13, two or more holes a may be provided.

As a method of using such a ladder-like fabric, in addition to the above-described fixing structure, use as a hanging tool is also conceivable. For example, the ladder-like woven fabric is hung on a wall or the like, and hooks or hangers are hung on the holes of the ladder-like woven fabric to suspend small items or laundry.
Conventional ladder-shaped fabrics are slightly difficult to use as a hanging tool because the holes are small or the holes gradually become smaller with time. (With the above fixing structure, there is no problem even if the hole is closed once fixed.) In this respect, according to the present invention, the hole is sufficiently opened, and the hole is maintained for a long time. Therefore, it can withstand repeated use such as hooking and removing.

Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
The kite yarn 4 may be a multifilament yarn instead of a monofilament.
In this case, it is desirable to apply a strong twist to make it difficult to be crushed.
The diameter of the multifilament yarn is preferably 0.2 mm to 0.6 mm, and the twist is preferably about 80 to 240 turns / m. More preferably, it is 100 to 150 turns / m, and more preferably about 120 turns / m.

  The bridging portion A ″ is configured by squeezing the eight wefts 2 (four sets) of the band portion A ″, but the numbers are merely examples, and the bridging portions are 20 (10 sets) or 30 (15 sets). A pair of weft yarns 2.

In the first embodiment, when weaving the warp 3 (31, 32, 33, 34) for the weft 2 in the weft 2, the middle two 32, 33 straddle the weft 2 by 8 (4 sets) at both ends. The two pieces 31 and 34 were arranged so as to straddle the four wefts 2 (two sets).
For example, as shown in FIG. 14, the two wefts 31 and 34 at both ends may of course straddle 8 weft yarns (4 sets).

However, as shown in FIG. 14, when all the warp yarns 3 (31, 32, 33, 34) straddle eight weft yarns (four sets), it is good if there is only one warp yarn 4. If the kite thread 4 is put on both sides of the drawing warp thread 3 (31-34) as shown in FIG.
In order for the kite thread 4 to squeeze or hold the warp 3 and the weft 2, the kite 4 and the warp 3 must cross.
(If they do not cross, the warp yarn 4 will get over the warp yarn 3 and the warp yarn 3 and the weft yarn 2 cannot be forced.)
If the warp yarn 4 is put on both sides of the warp yarn 3 as in the first modification, and the warp yarn 3 and the warp yarn 4 straddle the weft 2 at the same pitch, the crossing will not occur on either side. Come on.
Therefore, when the warp yarn 4 is put on both sides of the warp yarn 3 as in Modification 1, at least the warp yarn 3 adjacent to the warp yarn 4 is woven into the weft at a pitch different from that of the warp yarn 4, and the bridging portion So that the warp yarn 4 and the warp warp yarn 3 cross each other.
