Even if it is possible to set a pile in a certain direction and heat set it, it is difficult to make the pile direction of all pile fabric piles constant, resulting in variations in the set direction.
In particular, in a thick pile fabric, since the pile layer becomes a heat insulating layer, it is difficult to heat set at a constant temperature from the pile surface to the pile root, and the set temperature varies.
In a pile fabric having a high pile density, one adjacent pile supports the other pile, making it difficult to strongly incline the pile.

  Accordingly, an object of the present invention is to obtain a pile fabric for a cleaning brush that has no variation in the inclination direction and the inclination angle of the pile and has a stable quality.

  In the pile fabric for cleaning brushes according to the present invention, (a) the weft yarns that are sequentially driven into the openings formed by the core warp 31 having a low reduction rate and the fastening yarn 32 having a high reduction rate are woven on the upper and lower sides of the core warp 31. The base yarn is divided and tightened to the core warp 31 by the fastening warp 32, and (b) the pile yarns woven into the ground organization are front and back side wefts 12 and intermediate wefts 41 that are back and forth in the warp direction 54. And the rear end side weft 22 are locked to the ground structure by at least three wefts 12, 41, 22, and pass under the front end side weft 12 woven under the core warp 31 to penetrate the front pile piece 11, and under the rear end side weft 22 woven above the core warp 31, the rear end pile piece 21 is erected, and from the front end pile piece 11 to the rear end side weft 22. Continued pile yarn sinking 3 constitutes a first pile 52 over the intermediate weft 41, and (c) a tip pile piece 11 standing under the tip weft 12 woven under the core warp 31 It stands up and down between the front-side adjacent weft 13 and the front-side weft 12 woven before and after the front-side weft 12 and above the core warp 31, and The rear-end-side pile piece 21 that stands under the rear-end-side weft 22 and rises up and down the rear-end-side weft 22 and the rear-end-side adjacent weft 23 that is woven under the core warp 31 and the rear end. (E) The tip pile piece 11 is separated from the tip side adjacent weft 13 around the tip side weft 12 woven under the core warp 31. Is inclined toward the rear of the warp direction 54, which is the direction, F) The rear-end-side pile piece 21 is inclined toward the rear in the warp direction 54, which is the direction away from the rear-end-side weft 22, centering on the rear-end-side weft 22 woven above the core warp 31. This is the first feature (see FIGS. 1, 2, 3, and 4).

  Therefore, the first requirement of the cleaning brush pile fabric according to the present invention is that the ground structure has a two-layer structure in which wefts are woven into the upper side and the lower side of the core warp 31, that is, in FIG. As shown in an enlarged view, the core warp 31 having a small reduction rate is in a tension state in the ground structure, while the warp yarn 32 having a high reduction rate is in a relaxed state in the ground structure. The two-layer structure in which the wefts that are sequentially driven into the opening to be formed are woven into the upper and lower sides of the core warp 31 in tension, and as a result, the ground structure is woven into the upper and lower sides of the core warp 31 It is in the point to become.

  In the present invention, the “warp reduction ratio” means the woven warp length (Y) and the woven fabric constant length (X) with respect to the woven fabric constant length (X) in the warp direction. (Z = Y−X) ratio (ε = 100 × Z / X), and the shrinkage ratio (ε1) of the core warp is smaller than the shrinkage ratio (ε2) of the warp (ε1 <ε2) Means that the amount of warp yarn (hanging amount) required to weave a certain length (X) of the fabric is larger than the amount of core warp yarn (hanging amount), It means that the warp yarn is bent larger than the core warp yarn for a certain length (X) of the woven fabric, and the core warp yarn is bent less than the warp yarn and is woven in a straight line.

  A second requirement of the pile fabric for a cleaning brush according to the present invention is that the wefts woven on the upper side and the lower side of the core warp 31 are fastened to the core warp 31 by the tightening warp 32, that is, In the ground structure constituting the layer structure, the front-side weft 12 woven below the core warp 31 is fastened to the core warp 31 so as to be lifted by the tightening warp 32, and is woven above the core warp 31. Further, the rear end side weft 22 is tightened to the core warp 31 so as to be pushed down by the tightening warp 32.

  A third requirement of the pile fabric for a cleaning brush according to the present invention is that the pile yarn forms a first pile, that is, the pile yarn 33 includes the front-side weft yarn 12 that moves back and forth in the warp direction 54. The intermediate weft 41 and the rear end side weft 22 are locked to the ground structure by at least three wefts 12, 41, 22, and the front end pile piece 11 dives under the front end side weft 12 and stands up. The end pile piece 21 dives under the rear end side weft 22 and rises, and the pile yarn sinking thread 53 connecting the front end pile piece 11 and the rear end pile piece 21 passes over the intermediate weft 41. The first pile 52 is constructed.

  The fourth requirement of the pile fabric for a cleaning brush according to the present invention is that the rotational moment acting on the tip-side pile piece 11 in the direction of pushing back toward the rear in the warp direction 54 with the tip-side weft 12 as the rotation center, that is, FIG. The rotational moment acting clockwise on the tip-side pile piece 11 shown in FIG. 1, that is, the tip-side pile piece 11 passes under the tip-side weft 12 woven under the core warp 31 and moves back and forth in the warp direction 54. The tip side adjacent weft yarns 13 and the tip side weft yarns 12 are standing upright, and the passing tip side adjacent weft yarns 13 are woven above the core warp yarns 31 and protruded above the core warp yarns 31. The tip-side pile piece 11 is located at the lower position of the depression where the tip-side weft thread 12 through which the tip-side pile piece 11 has passed is woven into the lower side of the core warp 31 and falls below the core warp 31. , A rotational moment acts in a direction in which it is pushed down on the tip side adjacent weft yarn 13 at the high position, and the tip side weft yarn 12 at the low position becomes the rotation center of the rotation moment acting from the tip side adjacent weft yarn 13, and the tip side adjacent weft yarn 13. The tip-side pile piece 11 is inclined toward the rear in the warp direction 54 away from.

  The fifth requirement of the cleaning brush pile fabric according to the present invention is that the rotational moment acting on the rear end side pile piece 21 in the direction of pushing backward toward the rear side in the warp direction 54 with the rear end side adjacent weft 23 as the center of rotation, that is, , A rotational moment acting clockwise on the rear end side pile piece 21 shown in FIG. 4, that is, the rear end side pile piece 21 passes under the rear end side weft 22 woven above the core warp 31, In the warp direction 54, the rear end side wefts 23 that pass back and forth in the warp direction 54 and the rear end side wefts 22 pass up and stand, and the rear end side wefts 22 that pass through are woven into the upper side of the core warp 31 to form the core warp. The rear end side adjacent wefts 23 that are front and rear of the rear end side wefts 22 in the high position protruding above the upper side 31 are woven into the lower side of the core warp 31 and fall to the lower side of the core warp 31 Because it is in the lower position of the dimple, the rear end A rotational moment acts on the pile piece 21 in a direction in which it is pushed down by the rear end side weft 22 at the high position, and the rear end side adjacent weft 23 at the low position becomes the rotation center of the rotational moment applied from the rear end side weft 22. The rear end pile piece 21 is inclined toward the rear in the warp direction 54 away from the rear end side weft 22.

  In the present invention, the “front end side” and the “rear end side” are the first piles that are woven into the ground structure, bent in a W shape between three or more wefts, and locked to the ground structure. When distinguishing a pair of pile pieces standing up from both ends of the sagging yarn as "pile pieces at one end" and "pile pieces at the other end", which is "one end" and which is the "other end"? There is a possibility of confusion, in order to avoid the confusion, a pair of pile pieces at both ends of the first pile is a term for distinguishing as "pile piece on the front end side" and "pile piece on the rear end side", The terms “front end side” and “rear end side” do not mean the driving order of three or more wefts woven into the ground structure in a W shape or the weaving order of pile fabrics.

  In the present invention, “the upper side of the core warp” and “the lower side of the core warp” refer to the “pile surface of the core warp” based on the core warp of the pile woven fabric with the pile surface placed horizontally on the table. “Side” means “upper side of core warp”, and “back side opposite to pile side of core warp” means “under side of core warp”. The terms “under the core warp” do not mean the vertical positional relationship of a plurality of wefts that are sequentially driven in the weaving process of a pile fabric that is woven horizontally.

  The second feature of the pile fabric for cleaning brushes according to the present invention is that, in addition to the first feature, (g) the non-pile portion 51 and the first pile 52 where the first pile is not formed are the core warp 31 and the fastening yarn 32. Are formed alternately in the warp direction 54, and (h) the front-end-side adjacent weft 13 front and rear of the front-end weft 12 of the first pile 52 and the rear-end-side adjacent weft 23 front and rear of the rear-end side weft 22, respectively. The point is that non-pile portions 51 and 51 are arranged in front of and behind the first pile 52 (see FIGS. 9, 10, 11, and 12).

  A third feature of the pile fabric for a cleaning brush according to the present invention is that, in addition to the second feature, the non-pile portion 51 where the first pile is not formed and the first pile 52 are alternately formed in the weft direction 55 along the weft. (See FIGS. 9, 10, 11, and 12).

  The fourth feature of the pile fabric for a cleaning brush according to the present invention is that, in addition to any of the first, second and third features, the first pile in the warp direction 54 along the core warp 31 and the warp 32. The pile row in which 52 is formed and the non-pile row in which the first pile is not formed in the warp direction 54 along the core warp 31 and the warp yarn 32 are formed in a striped stripe pattern following the warp direction 54. In the point.

  A feature of the pile fabric according to the present invention is that weft yarns that are sequentially driven into an opening formed by a core warp 31 having a low reduction rate and a fastening warp 32 having a high reduction rate are woven into an upper side and a lower side of the core warp 31. The pile yarns constituting the structure and woven into the ground structure are constituted by at least three wefts 12, 41, 22 of the front side weft 12, the intermediate weft 41, and the rear end side weft 22 that move back and forth in the warp direction 54 The back end side weft thread woven into the upper side of the core warp 31 while standing on the upper end of the core warp thread 31 while standing under the front end weft thread 12 locked to the ground structure and woven under the core warp thread 31. 22, the rear end pile piece 21 is erected, and the pile yarn sinking 53 that continues from the front end pile piece 11 to the rear end weft 22 passes over the intermediate weft 41. Composed and wick The tip-side pile piece 11 that stands under the tip-side weft 12 woven under the yarn 31 lies around the tip-side weft 12 before and after the tip-side weft 12 and is adjacent to the tip side weft. 13 and the front end side weft yarn 12, and the rear end pile piece 21 standing up through the rear end side weft yarn 22 woven above the core warp yarn 31 is The front pile piece 11 is erected by passing between the rear end side adjacent weft 23 and the rear end side weft 22 woven before and after the side weft 22 and below the core warp 31. 31 is inclined toward the rear in the warp direction 54, which is a direction away from the front-side adjacent weft 13, with the front-end weft 12 woven in the lower side as the center, and the rear-end-side pile piece 21 is located above the core warp 31. The back end side weft 2 centered on the back end side weft 22 woven into Inclined rearward in the warp direction 54 is a direction away from the inclination angle of the tip end pile piece 11 and the rear side pile piece 21 is that it is less 70 degrees 20 degrees.

The pile piece of the pile fabric for a cleaning brush of the present invention includes the front and rear wefts that sandwich the pile piece, that is, the front-end pile piece 11 and the rear-end pile piece 21, that is, the front-end side. In the pile piece 11, the front end side weft 13 and the front end side weft 12, and in the rear end side pile piece 21, the rear end side weft 22 and the rear end side adjacent weft 23 are above and below the core warp 31, respectively. Sides, that is, the high position and the low position are woven, and the high position wefts (the front end side adjacent wefts 13 and The rotational moments, which are the fourth and fifth requirements of the present invention for pushing down the pile pieces (the tip-side pile piece 11 and the trailing-end pile piece 21) from the rear end side weft 22) to the rear side in the warp direction 54, that is, The clockwise rotation moment in Fig. 4 It acts.
Therefore, according to the present invention, it is not necessary to heat-set by pushing down, and the pile piece is inclined in a certain direction due to the engagement structure with the ground structure, and there is no variation in the inclination direction and the inclination angle, and the cleaning is stable in quality. A pile fabric for the brush is obtained.

  According to the present invention, the ground structure forms a two-layer structure that is the first requirement, the weft is fastened to the core warp 31 by the second warp 32 that is the second requirement, and the pile yarn is the third Therefore, the pile fabric for a cleaning brush having a stable pile standing shape, a high pile pull-out strength, and excellent durability can be obtained.

The number of wefts required to lock the first pile 52 to the ground structure may be three, that is, the front end side weft 12, the intermediate weft 41, and the rear end side weft 22, but FIG. 1 and FIG. 3 and 4, the number of intermediate wefts 41 can be increased to 4 or more.
In this case, in order to form the first pile 52, the pile yarn sag 53 passes over at least one of the intermediate wefts 41a, 41b, 41c, 41d,.
In this way, as long as the pile yarn sag 53 crosses over any one of the intermediate wefts, it does not matter whether the pile sink 53 crosses over any other intermediate weft.
In FIG. 1, a structure point indicating a double circle “◎” indicates a structure point where it is unquestionable whether it exceeds or does not exceed the weft.

In FIG. 6, two pairs of pile yarns 33a and 33b are arranged with respect to a pair of ground warps of one core warp 31 and one fastening warp 32, and these warp yarns are the smallest unit. FIG. 7 is a side view of a pile fabric woven according to the weave structure of FIG. 6, and FIG. 8 is a view of the weave structure of FIG. FIG. 2 is a perspective view of a pile fabric woven according to FIG.
As shown in FIGS. 6, 7, and 8, a pair of ground warps, that is, a pair of pile yarns 33 a and 33 b for one core warp 31 and one tightening warp 32. The first pile 52 constituted by the first pile yarn 33a and the first pile 52 constituted by the second pile yarn 33b are alternately continued in the warp direction 54.
The first pile rear end pile piece 21 constituted by the first pile yarn 33a and the first pile front pile piece 11 constituted by the second pile yarn 33b are adjacent to each other in the warp direction 54. The rear-end-side weft yarn 22 that locks the rear-end pile piece 21 of the first pile constituted by the first pile yarn 33a engages the front-end-side pile piece 11 of the first pile constituted by the second pile yarn 33b. The rear-end-side weft 22 that corresponds to the front-end adjacent weft 13 before and after the front-end weft 12 and that engages the rear-end pile piece 21 of the first pile constituted by the second pile yarn 33b is the first pile yarn. Position corresponding to the rear-end-side adjacent weft 23 back and forth to the front-end weft 12 that locks the front-end pile piece 11 of the first pile constituted by 33a In the engagement.
Similarly, the rear pile piece 21 of the first pile constituted by the second pile yarn 33b is adjacent to the leading pile piece 11 of the first pile constituted by the first pile yarn 33a in the warp direction 54. The rear-end-side weft yarn 22 that engages the rear-end-side pile piece 21 of the first pile constituted by the first pile yarn 33a engages the tip-side pile piece 11 of the first pile constituted by the second pile yarn 33b. The rear end side weft 22 that corresponds to the front end side adjacent weft 13 that extends back and forth to the front end side weft 12 to be stopped and that locks the rear end pile piece 21 of the first pile constituted by the second pile yarn 33b is the first end weft 22 Corresponds to the rear end side adjacent wefts 23 back and forth to the front end side wefts 12 for locking the front end side pile pieces 11 of the first pile constituted by the pile yarns 33a In the location relationship.

9, 10, 11, and 12, like the first pile 52 illustrated in FIGS. 6, 7, and 8, are locked to the ground structure by three wefts 12, 41, and 22 as a minimum unit. The made first pile 52 is illustrated.
However, the pile fabric illustrated in FIGS. 9, 10, 11, and 12 is different from the pile fabric illustrated in FIGS. 6, 7, and 8, and a pair of ground warp yarns, that is, one core. One pile yarn 33 is disposed for the warp 31 and one tightening warp 32, and is disposed on each of the two adjacent pile yarns 33a and 33b and each of the two pile yarns 33a and 33b. The structure diagram formed by the entanglement of the core warp 31 and the single warp 32 has a different striking phase by 3 picking motions.

That is, in the pile fabric shown in FIGS. 9, 10, 11, and 12, the first pile yarn 33a in two adjacent pile yarns is related to a set of three weft yarns 12b, 41, and 22b. When the stopped first pile 52 is formed, the adjacent second pile yarn 33b forms the non-pile portion 51 without being entangled with a set of three wefts 12b, 41, and 22b, and only for three striking movements. When the striking phase is changed and the first pile yarn 33a forms the non-pile portion 51 without being entangled with the set of three weft yarns 12a, 41, and 22a, the second pile yarn 33b is a set of three. The first pile 52 locked to the wefts 12a, 41, and 22a is formed.
As a result, as shown in FIG. 12, the first pile yarn 33a and the second pile yarn 33b that are adjacent to each other have the non-pile portion 51 and the first pile 52 where the first pile is not formed, the core warp 31 and the fastening warp 32, respectively. Of the first pile yarn 33a and the first pile yarn 33a and the non-pile portion 51 formed by the first pile yarn 33a and the first pile yarn 33b. The first pile 52 to be formed and the non-pile portion 51 to be formed of the second pile yarn 33b are alternately formed in the weft direction 55 along the weft.

  FIG. 10 is a side view of a pile fabric appearing in a cross-section E-F of the organization chart of FIG. 9, illustrating the side surfaces of the no-pile portion 51 and the first pile 52 formed by the first pile yarns 33a alternately. 11 is a side view of a pile fabric appearing in a cross-section GH of the organization chart of FIG. 9, and illustrates the side surfaces of the no-pile portion 51 and the first pile 52 formed by the second pile yarns 33b alternately.

6, 7, and 8, the pile fabrics shown in FIGS. 9, 10, 11, and 12 illustrate the pile pile 11 on the front end side of each first pile 52. A portion between the first pile 52 adjacent to the rear end side pile piece 21 in the warp direction 54 is a non-pile portion 51, and the front end pile piece 11 and the rear end side pile piece 21 of each first pile 52 are arranged in the warp direction 54. No adjacent first pile 52 is touched, and therefore the leading pile piece 11 and the trailing pile piece 21 of each first pile 52 are supported by any adjacent adjacent first pile 52 in the warp direction 54. Absent.
6, 7, and 8, the pile fabrics shown in FIGS. 9, 10, 11, and 12 illustrate the first pile 52 and the rear end of the first pile 52. When the rotational moment which is the fourth and fifth requirements of the present invention, that is, the clockwise rotational moment in FIG. 4, acts on the side pile piece 21, the rotational moment acts on any of the first adjacent in the warp direction 54. The pile 52 is not disturbed.
Therefore, according to the present invention, it is not necessary to heat-set by pushing down, and the pile piece is inclined in a certain direction due to the engagement structure with the ground structure, and there is no variation in the inclination direction and the inclination angle, and the cleaning is stable in quality. A pile fabric for a brush can be obtained reliably.

Further, as apparent from the pile fabric shown in FIGS. 6, 7, and 8, in the pile fabric shown in FIGS. 9, 10, 11, and 12, the tip pile piece of each first pile 52 is provided. 11 and the first pile 52 adjacent to the rear end side pile piece 21 in the weft direction 55 are also non-pile portions 51, and the front end pile piece 11 and the rear end side pile piece 21 of each first pile are in the weft direction 55. It is not supported by any adjacent first pile 52 in FIG.
Therefore, according to the present invention, it is not necessary to heat-set by pushing down, and the pile piece is inclined in a certain direction due to the engagement structure with the ground structure, and there is no variation in the inclination direction and the inclination angle, and the cleaning is stable in quality. A pile fabric for a brush can be obtained reliably.

Accordingly, there is no pile in which the first pile 52 is formed in the warp direction 54 along the core warp 31 and the warp yarn 32, and no first pile is formed in the warp direction 54 along the core warp 31 and the warp yarn 32. When the pile row is formed in a striped stripe pattern following the warp direction 54, the first pile portion 11 and the rear pile portion 21 of each first pile in each pile row are adjacent to each other in the weft direction 55. It will be in the free state which cannot be supported by 52.
Therefore, according to the present invention, the pile piece is inclined in a certain direction due to the engagement structure with the ground structure without being pushed down and heat-set, and the quality is further stabilized without variation in the inclination direction and the inclination angle. A pile fabric for the cleaning brush is surely obtained.

The perspective view of the pile fabric illustrated in FIG. 2B is the same as the perspective view of the pile fabric illustrated in FIG. 3, and the perspective view of the pile fabric illustrated in FIG. 8 is the same as the perspective view of the pile fabric illustrated in FIG. 10, and the perspective view of the pile fabric illustrated in FIG. 10 (b) and FIG. 11 (b) is the pile fabric illustrated in FIG. Since it becomes the same as a perspective view, the perspective view of the pile fabric which those fraction drawings (b) illustrate is omitted.

As described above, the number of wefts required to lock the first pile 52 to the ground structure may be three, that is, the front side weft 12, the intermediate weft 41, and the rear end side weft 22. It is also possible to increase the number of intermediate wefts 41 to 4 or more as in the pile woven fabric shown in FIG. 1, FIG. 2, FIG.
Accordingly, in order to form the first pile 52, it is preferable that the pile yarn sag 53 passes over at least one intermediate weft of the plurality of intermediate wefts 41a, 41b, 41c, 41d. I can do it.
As long as the pile sag 53 exceeds any one of the intermediate wefts, the pile sag 53 is shown as a double circle “◎” at the texture point in the structure diagram of FIG. It does not matter whether any other intermediate weft is exceeded or not.

  FIG. 5 (a) is a reproduction of the pile fabric shown in FIGS. 2, 3 and 4, and there are seven intermediate wefts 41a and 41b between the front end side weft 12 and the rear end side weft 22. 41c, 41d, 41e, 41f, and 41g are interwoven with the intermediate weft 41a below the core warp 31 and lifted to the core warp 31 by the tightening warp 32, and the intermediate weft 41b is woven above the core warp 31. Thus, the intermediate warp 41c is woven into the upper side of the core warp 31 and pressed against the core warp 31 by the settling thread 53, and the intermediate weft 41d is woven into the lower side of the core warp 31.
