FIG. 2 is a schematic cross-sectional view for explaining the weaving method of the gauze fabric according to this embodiment. FIG. 3 is a perspective view showing a conventional gauze fabric with creases and a gauze fabric according to this embodiment. FIG. 4 is a schematic cross-sectional view for explaining the weaving method of the gauze fabric according to the first modification of the present embodiment.

  Hereinafter, a method for weaving a gauze fabric according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a gauze fabric according to this embodiment. FIG. 2 is a schematic cross-sectional view for explaining the weaving method of the gauze fabric according to this embodiment. The gauze fabric according to this embodiment is woven by a jacquard loom.

  As shown in FIG. 1, the gauze fabric 1 includes a foundation 20, a first wide fold 21 that rises on one side or the other side of the foundation 20, and a second wide fold that rises on the other side or one side of the foundation 20. 22 is a multi-layered gauze fabric having a three-layer structure. Further, a portion where the first and second wide folds 21 and 22 are knotted with the foundation 20 is a knot portion 24.

  The first wide fold 21 is a structure formed by weaving the first upper warp 11, the third upper warp 13 and the weft 10 by gauze weaving, and the second wide fold 22 is composed of the second upper warp 12 and the fourth upper warp 12. This is a structure formed by weaving the upper warp yarn 14 and the weft yarn 10 by gauze weaving. The foundation 20 is a structure formed by weaving part of the first lower warp 15 and the second lower warp 16 with the weft 10 and gauze weave.

  In the knot portion 24, the first to fourth upper warps 11-14 and the first and second lower warps 15, 16 are woven together with the weft 10, and the first and second wide folds 21, 22 are woven together. The front and rear are connected to the foundation 20.

  In FIG. 1, the first upper warp 11 and the third upper warp 13 are shown by solid lines, the second upper warp 12 and the fourth upper warp 14 are shown by dotted lines, and the first lower warp 15 and the second lower warp 16 are one point. Shown with a chain line. The upper warps 11 to 14 are supplied from the beam in a loose and loose state, and the lower warps 15 and 16 are supplied from the beam in a tight and tight state.

  As shown in FIG. 1, large cavities are formed inside the wide folds 21 and 22. Therefore, when the folds are formed continuously, the shape is not three-dimensionally fuller than wide folds in which the folds projecting like a conventional fold fabric are lined up, rather than in a shape where the folds protrude continuously. It becomes a multi-gauze fabric of a simple shape.

  FIG. 3 is a perspective view showing a conventional gauze fabric in which folds are formed and a gauze fabric according to the present embodiment. In FIG. 3, the right side is a multiple gauze fabric in which a conventional fold is formed, and the left side is in the present embodiment. It is a multiple gauze fabric in which such wide folds are formed.

  As shown in the figure, a conventional woven fabric with folds has a shape in which elongated folds in a cross section in which the root portions on both sides of the folds are close to each other protrude closely, whereas the width of this embodiment is wide. The gauze fabric in which the folds are formed has a shape in which the wide folds are swelled widely, and gives a plump impression completely different from the conventional one.

  Also, with regard to the touch comfort, in the conventional fabric with folds formed, no space is formed inside the folds, so that it feels stiff and firm even when touched by a person. According to the gauze fabric 1 according to the present invention, the wide folds 21 and 22 are woven with a coarse gauze woven fabric, and a large cavity is formed inside the wide folds 21 and 22, so that even when touched by a person, It will be much more flexible to the touch. Moreover, since the cavity inside the wide folds 21 and 22 becomes an air layer, the gauze fabric 1 is excellent in heat retention and water absorption.

  Further, as shown in FIG. 1, on the left side in the drawing, the second wide fold 22 is located on the front side (one side) and the first wide fold 21 is located on the back side (the other side), whereas On the right side, the first wide fold 21 is located on the front side, and the second wide fold 22 is located on the back side. In this embodiment, the front and back positions of the wide folds 21 and 22 can be freely changed. Therefore, it is possible to express a desired pattern by making the colors of the upper warp yarns 11 to 14 and the weft yarns 10 different.

  While the configuration of the gauze fabric 1 has been described above, a method for weaving the multiple gauze fabric 1 will be described with reference to FIG. The gauze fabric 1 according to the present embodiment is woven with a jacquard loom capable of changing the lashing position. FIG. 2 shows a state in which the wide folds 21 and 22 are unfolded, omitting the slip (slide) of the joint portion 24 by striking for convenience of explanation. In the drawing, the wide fold 21 is located on the front side, and the wide fold 22 is located on the back side.

  First, a description will be given starting from the formation of the wide folds 21 and 22 at the same time as the upstream nodal portion 24-1. The jacquard loom according to the present embodiment can change the striking position steplessly, and after striking the weft at the rear end of the knot portion 24-1 to the reference position o shown in FIG. The wefts 10 of the wide folds 21 and 22 are beaten and beaten while shifting to the upstream side (right side in the figure) of the dough conveying direction.

  Specifically, the first weft a (the leftmost weft in the figure) of the wide fold 22 is beaten to a position 1 mm away from the reference position o, and then the first weft b of the wide fold 21 is moved from the reference position o. Beat to 1mm away. After that, the second weft c of the wide fold 22 is moved to a position 2 mm away from the reference position, the second weft d of the wide fold 21 is moved to a position 2 mm away from the reference position, and the beat position is sequentially set to the reference position o. The wide folds 21 and 22 are woven while being separated from each other.

  In the present embodiment, the positions at which each weft is driven by the beating (the distance from the reference position o) are 1 mm for the wefts a and b, 2 mm for the wefts c and d, 3 mm for the wefts e and f, 4 mm for the wefts g and h, Wefts i and j are 5 mm, Wefts k and l are 6 mm, Wefts m and n are 7 mm, Wefts p and q are 8 mm, Wefts r and s are 9 mm, Wefts t and u are 10 mm, Wefts v, w, x, and y Is 11mm.

  After weaving the wide folds 21 and 22, the knot portion 24-2 is subsequently woven. In the knot portion 24-2, the first to fourth upper warps 11 to 14 and the first and second lower warps 15 and 16 are woven, and the three layers of the base 20 and the wide folds 21 and 22 are knotted. Is done.

  Specifically, first, the first to fourth wefts a ′, b ′, c ′, and d ′ of the knot portion 24 are beaten to a position 11 mm away from the reference position o, and then the knot portion 24. The fifth and sixth wefts e ′ and f ′ are beaten to the reference position o at once. Since the upper warps 11-14 are in a loose tension state and the lower warps 15, 16 are in a tight tension state, the upper warps 11-14 in the tight warp lower yarns 15, 16 are beaten. Is pulled out and slips, and the knot portion 24-2 is shifted to the downstream side in the transport direction (left side in the figure).

  At this time, the take-up roller of the gauze fabric 1 is always rotating, and the woven fabric is always conveyed. Therefore, the weft at the rear end of the knot portion 24-1 at the reference position o is wide. While weaving 21, 22, it moves to the downstream side. Therefore, when the knot portion 24-2 is shifted to the reference position o by the beating of the warps e 'and f', the amount of the gauze fabric 1 that has been conveyed, that is, the conveyance of the wide folds 21 and 22 after the start of weaving. An interval is generated between the nodal portion 24-1 and the nodal portion 24-2 by an amount corresponding to the length.

  In addition, as the knot portion 24-2 is displaced, the portions of the first and second wide folds 21 and 22 that have already been woven have no place to go and swell away from the lower warps 15 and 16 (base 20), respectively. . When the nodule portion 24-2 is moved to the reference position o, as shown in FIG. 1, wide folds are raised on both sides, and wide folds 21 and 22 are formed at the same time.

  After the wefts e 'and f' at the rear end of the knot portion 24-2 are thus beaten to the reference position o, the subsequent folds 21 and 22 are continuously woven in the same manner. Thereby, the multiple gauze fabric 1 shown in FIG. 1 is woven.

  As described above, the gauze fabric 1 according to the present embodiment has been described in detail. However, according to the present embodiment, wide folds that swell in a wide three-dimensional manner can be formed. It is possible to provide a lightweight gauze fabric that is soft and soft to the touch.

  In particular, in the present embodiment, a soft gauze fabric having a wide mesh and a wide fold are combined, and high flexibility and light weight can be ensured. Moreover, in this embodiment, heat retention and water absorption can also be improved with a wide pleat.

  Moreover, in this embodiment, a three-dimensional pattern can be suitably taken out by using the thread | yarn of a different color for the warps 11-16 and the weft 10. FIG. For example, the first and third upper warps 11, 13 and the weft 10 incorporated therein are black yarns, and the second and fourth upper warps 12, 14 and the weft 10 incorporated therein are white yarns. A desired pattern can be obtained by appropriately changing the front and back positions of the first wide fold 21 and the second wide fold 22.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the position at which each weft 10 is driven and moved can be changed as appropriate, and may be a position that gradually moves away from the reference position as the wide folds 21 and 22 are woven. Further, the size of the wide folds 21 and 22 can be changed by appropriately changing the number of the wefts 10 constituting the wide folds 21 and 22.

  Moreover, in the said embodiment, although the wide folds 21 and 22 are formed one each on the both sides (front side and back side) of the foundation ground 20, you may make it form a wide fold only on one side of the foundation ground 20. A plurality of wide folds may be formed on one side. If at least one wide crease is formed on at least one side, it is possible to realize a multiple gauze fabric that is soft to the touch and excellent in heat retention.

  Subsequently, Modification 1 of the present embodiment will be described. FIG. 4 is a schematic cross-sectional view for explaining a method for weaving a gauze woven fabric according to Modification 1 of the present embodiment, and shows a state in which wide folds are developed as in FIG.

In addition to 36, a third lower warp 37 and a fourth lower warp 38 are further different. Therefore, when the foundation 40 is counted as two layers, the multiple gauze fabric 2 becomes a four-layer fabric.

  In the first modification, the first upper warp 31 and the third upper warp 33 and the weft 30 which are loosely tensioned are formed to form the first wide fold 41, and the second upper warp 32 and the fourth upper warp 34 which are loosely tensioned. And the weft 30 are woven together to form a second wide fold 42.

  Further, a foundation ground 40 is formed by weaving a part of the first to fourth lower warps 35 to 38 and the weft 30 tightly, and the first lower warp 35 and the second lower warp 36 are formed in the foundation 40. A gauze woven portion 43 is formed by weaving a part and the weft 30. In the knot portion 44, the first to fourth upper warps 31 to 34 and the first to fourth lower warps 35 to 38 are woven together with the weft 30 so that the first and second wide folds 41 and 42 are woven. Knotted with base 40. The gauze woven portion 43 is woven in parallel with the wide folds 41 and 42 and the knot portion 44.

  In the first modification, the first wide fold 41 swells on the front side and the second wide fold 42 swells on the back side between the nodule portion 44-1 and the nodule portion 44-2. Between the nodule portion 44-2 and the nodule portion 44-3, both the first and second wide folds 41 and 42 swell to the front side, and the gauze woven portion 43 is exposed on the other side (back side). ing.

  According to the first modification, the same effect as the above embodiment is achieved, and a three-dimensional multiple gauze fabric is formed by adding the third and fourth lower warps 37 and 38 as the fourth layer. It is possible to express various patterns.

  For example, the first and third upper warps 31, 33 and the weft 30 incorporated therein are black yarns, the second and fourth upper warps 32, 34 and the weft 30 incorporated therein are white yarns, and the first Further, the second lower warp yarns 35 and 36 and the weft 30 incorporated in the second lower warp yarns 35 and 36 are red yarns, and the side where the first wide folds 41 and 42 are formed is changed as appropriate. It is possible to express a simple pattern.
