Abstract

<P>PROBLEM TO BE SOLVED: To prevent the occurrence of interference fringes when projecting a digital image, and to implement easy and low-cost weaving works. <P>SOLUTION: The woven fabric is constituted by mutually intersecting the warp (8) and the woof (9). The textile is composed of broken twills. Thus, the float part (11) of the warp (8) on one side never continue in adjacent vertical and horizontal directions. In addition, the float part (11) is arranged intermittently in an oblique direction, and regarding the arrangement in the adjacent oblique directions, and moreover, the continuous number of the float part (11) changes. A synthetic resin coating layer is formed on at least one side, using the woven fabric (6) as a core material, and then the planar spreadable flexible sheet is formed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、織物および平面展開可能な可撓性シートに関し、さらに詳しくは、デジタル画像を投射した際に干渉縞の発生を防止できるうえ、製織作業を簡単で安価に実施できる織物と、これを芯材として用いた平面展開可能な可撓性シートに関する。   The present invention relates to a woven fabric and a flexible sheet that can be flattened. More specifically, the present invention can prevent the generation of interference fringes when a digital image is projected, and a woven fabric that can be easily and inexpensively woven. The present invention relates to a flexible sheet that can be developed in a plane and used as a core material.

一般に、プロジェクター等から投射された画像を映し出すスクリーンには、不使用時はロール状に巻き取られて収納され、使用時に平面展開される可撓性シートがある。この可撓性シートは、使用時に平面状態を確りと維持できるように、ガラス繊維などを平織にした基布を芯材として、その表面に塩化ビニル樹脂などのコーティング層を形成してある。このコーティング層は、過剰に厚く形成すると巻取り収納が困難となり、また嵩高となって好ましくない。このため、このコーティング層は薄く形成され、その表面には、上記の基布の織り組織による規則的な凹凸模様が現れる。   In general, a screen that projects an image projected from a projector or the like includes a flexible sheet that is wound and stored in a roll shape when not in use, and is flattened when in use. This flexible sheet is formed with a coating layer of vinyl chloride resin or the like on its surface using a base fabric made of plain glass fibers or the like as a core material so that the flat state can be reliably maintained during use. If this coating layer is formed excessively thick, it is difficult to wind and house it, and it is bulky, which is not preferable. For this reason, this coating layer is formed thin, and the regular uneven | corrugated pattern by the woven structure of said base fabric appears on the surface.

一方、上記のプロジェクター等から投射される画像は、今日ではデジタル化したものが多く、その画質は、例えば家庭用に普及しているいわゆるホームシアターにあっては、高い品質の映像が望まれている。このデジタル画像は、規則的に整列した画素から構成されており、スクリーンに投射された画像を構成する各画素線の幅は、画像のサイズ、即ちインチ数に応じて大きくなる。このため、このデジタル画像を、前記の平織の基布からなる可撓性シートに投射すると、少なくともいずれかの画像サイズにおいて、上記の画素線と基布の織目による規則的な凹凸模様とが干渉し、干渉縞(いわゆる、モアレ)を発生させて画像の品質を低下させる問題がある。   On the other hand, the images projected from the projectors and the like are often digitized today, and the image quality is desired to be high-quality images in so-called home theaters that are widely used for home use, for example. . This digital image is composed of regularly arranged pixels, and the width of each pixel line constituting the image projected on the screen increases according to the size of the image, that is, the number of inches. For this reason, when this digital image is projected onto the flexible sheet made of the plain weave base fabric, at least one of the image sizes has a regular uneven pattern due to the pixel lines and the base fabric texture. There is a problem that interference occurs and interference fringes (so-called moire) are generated to lower the image quality.

従来、上記の干渉縞の発生を防止するため、上記の基布の織目を不規則にすると好ましいことが知られており、例えば、繰り返し単位が大きいアムンゼン織り基布を用いることが提案されている(例えば、特許文献1参照。)。   Conventionally, in order to prevent the occurrence of the interference fringes, it has been known that it is preferable to make the texture of the base fabric irregular. For example, it has been proposed to use an Amundsen woven base fabric having a large repeating unit. (For example, refer to Patent Document 1).

このアムンゼン織りは、例えば、6乃至9枚ヘルドのものが用いられ、経糸66本×緯糸40本等の大きな繰り返し単位で織り組織が形成される。この1つの繰り返し単位内では経糸や緯糸の浮部が不規則に配置されており、このため、プロジェクターから投射されたデジタル画像との干渉が低減され、干渉縞の発生が防止される。   As this Amundsen weaving, for example, one having 6 to 9 healds is used, and a weaving structure is formed by large repeating units such as 66 warps × 40 wefts. Within this single repeating unit, the floating portions of warps and wefts are irregularly arranged, so that interference with the digital image projected from the projector is reduced and the occurrence of interference fringes is prevented.

しかしながら、このアムンゼン織りは、上記のようにヘルド枚数が多く、繰り返し単位は大きく複雑で、緻密な計算に基づき織り組織を形成する必要があり、基布の製織作業が煩雑で安価に実施できない問題がある。   However, this Amundsen weaving has a large number of healds as described above, the repeating unit is large and complicated, and it is necessary to form a weaving structure based on precise calculation, and the weaving work of the base fabric is complicated and cannot be carried out at low cost. There is.

本発明の課題は上記の問題点を解消し、デジタル画像を投射した際に干渉縞の発生を防止できるうえ、製織作業を簡単で安価に実施できる織物と、これを芯材として用いた平面展開可能な可撓性シートを提供することにある。   The object of the present invention is to solve the above problems, prevent occurrence of interference fringes when a digital image is projected, and fabric that can be easily and inexpensively weaved, and planar development using this as a core material It is to provide a possible flexible sheet.

本発明は上記の課題を解決するために、例えば本発明の実施の形態を示す図1から図4に基づいて説明すると、次のように構成したものである。
即ち、本発明1は織物に関し、経糸(8)と緯糸(9)とを互いに交差してなる織物であって、片面における経糸(8)と緯糸(9)のうちの一方の織糸(10)の浮部(11)が、隣接する縦方向と横方向には連続せず、且つ、斜め方向には断続的に並ぶとともに、隣接する斜め方向では、この一方の織糸(10)の浮部(11)の連続数が異なることを特徴とする。
In order to solve the above problems, the present invention will be described as follows, for example, based on FIGS. 1 to 4 showing an embodiment of the present invention.
That is, the present invention 1 relates to a woven fabric, which is a woven fabric obtained by intersecting a warp yarn (8) and a weft yarn (9) with each other, and one woven yarn (10 ) Floating portions (11) are not continuous in the longitudinal and lateral directions adjacent to each other and are arranged intermittently in the diagonal direction, and in the adjacent diagonal direction, the floating portion of this one yarn (10) floats. The number of consecutive parts (11) is different.

また本発明2は平面展開可能な可撓性シートに関し、上記の本発明1の織物(6)を芯材として、その少なくとも片面に合成樹脂製コーティング層(7)を形成したことを特徴とする。   Further, the present invention 2 relates to a flexible sheet that can be developed in a plane, characterized in that a synthetic resin coating layer (7) is formed on at least one surface of the woven fabric (6) of the present invention 1 as a core material. .

上記の織り組織は、浮部の斜め方向の断続的な並びが、隣接する斜め方向での連続数と異なる。例えば、ある斜め方向の浮部の並びでは2つ置きに2つずつ連続して配置され、その隣りの斜め方向の並びでは3つ置きに1つずつ配置され、さらにその隣りの斜め方向の並びでは、浮部が全く形成されない。
このため、織り組織全体は、斜め方向の並びが乱れて形成されるので、この表面にデジタル画像が投射されると、画像をいずれの大きさに変化させても、干渉縞の発生が抑制される。
In the above woven structure, the intermittent arrangement of the floating portions in the oblique direction is different from the continuous number in the adjacent oblique direction. For example, every two floating portions arranged in a certain diagonal direction are arranged continuously every two, one in every three adjacent oblique directions, and one in every other oblique direction. Then, no floating part is formed.
For this reason, the entire woven structure is formed with a disordered arrangement in the oblique direction, so when a digital image is projected onto this surface, the occurrence of interference fringes is suppressed regardless of the size of the image. The

上記の織り組織は、上記の一方の織糸の浮部を、斜め方向に3以上連続させないと、干渉縞の発生を抑制し、しかも織り組織を簡単に構成できるので、好ましい。
この織り組織としては、具体的には例えば図3に示すように、経糸4本×緯糸4本からなる破れ斜紋を挙げることができる。この破れ斜紋は4枚朱子やトルコ朱子とも言われ、繰り返し単位が小さく、4枚のヘルドを用いて簡単に製織される。
The above woven structure is preferable because the occurrence of interference fringes can be suppressed and the woven structure can be easily configured unless the floating portion of the one woven yarn is continued three or more diagonally.
Specifically, as this weave structure, for example, as shown in FIG. 3, a broken oblique pattern consisting of 4 warps × 4 wefts can be mentioned. This broken oblique pattern is also referred to as a four-sheet satin or Turkish vermilion, and has a small repeating unit and is easily woven using four healds.

上記の浮部は、経糸と緯糸のいずれであってもよいが、経糸の浮部で構成すると、一層干渉縞の発生を抑制でき、好ましい。
これらの織糸の材質は、特定の繊維材料に限定されず、ポリエステル繊維などの合成繊維を用いることも可能であるが、ガラス長繊維を用いると、強度が高く不燃性であり、寸法安定性がよく、好ましい。
また、これらの織糸の太さは、特定のものに限定されないが、太過ぎると重量が大きくなるうえ収納時に巻取り難くなり、細過ぎると使用時に展開しても平面状に維持し難くなるので、通常は、20乃至140texの糸が用いられる。
また、これらの織糸で製織された織物の厚さも特定の寸法に限定されないが、同様の理由から、通常、厚さが0.05乃至0.30mmに設定される。
The floating part may be either a warp or a weft. However, it is preferable that the floating part is composed of a warp floating part because the generation of interference fringes can be further suppressed.
The material of these woven yarns is not limited to a specific fiber material, and synthetic fibers such as polyester fibers can also be used. However, when long glass fibers are used, the strength is high and nonflammable, and dimensional stability. Is preferable.
Further, the thickness of these woven yarns is not limited to a specific one, but if it is too thick, the weight increases and it becomes difficult to wind when stored, and if it is too thin, it becomes difficult to maintain a flat shape even when deployed. Therefore, usually a thread of 20 to 140 tex is used.
Further, the thickness of the fabric woven with these woven yarns is not limited to a specific dimension, but for the same reason, the thickness is usually set to 0.05 to 0.30 mm.

上記の織物を芯材として、これに樹脂製コーティングを形成する場合、使用する樹脂材料は、特定の種類に限定されず、一般に使用されている塩化ビニル樹脂などを用いることができる。
この場合、そのコーティング層の厚さも、特定の寸法に限定されないが、収納時の巻取り易さ等を考慮して、好ましくは、0.05乃至0.5mmの厚みに設定される。
When the resin fabric is formed on the woven fabric as a core material, the resin material to be used is not limited to a specific type, and a commonly used vinyl chloride resin or the like can be used.
In this case, the thickness of the coating layer is not limited to a specific dimension, but is preferably set to a thickness of 0.05 to 0.5 mm in consideration of ease of winding during storage.

本発明は上記のように構成され作用することから、次の効果を奏する。     Since the present invention is configured and operates as described above, the following effects can be obtained.

(1) 織り組織全体では、斜め方向の並びが乱れて形成されるので、この織物の表面にデジタル画像が投射されると、画像をいずれの大きさに変化させても、干渉縞の発生が抑制され、高い品質の映像を観賞することができる。 (1) Since the entire woven structure is formed in an oblique arrangement, if a digital image is projected onto the surface of the fabric, interference fringes will occur regardless of the size of the image. Suppressed and can watch high quality video.

(2) 織り組織は、浮部の斜め方向での並びを断続的に配置し、隣接する斜め方向で並ぶ連続数を異ならせるだけでよく、例えば4枚のヘルドを用いた破れ斜紋など、簡単で小さな繰り返し単位により形成することができる。この結果、この織物の製織作業を簡単にして安価に実施でき、これを芯材にした可撓性シートを安価に提供することができる。 (2) For the weaving structure, it is only necessary to discontinuously arrange the floating parts in the diagonal direction and to change the number of continuous lines in the adjacent diagonal direction. And can be formed with small repeating units. As a result, the weaving operation of the woven fabric can be performed easily and inexpensively, and a flexible sheet using this as a core can be provided at a low cost.

以下、本発明の実施の形態を図面に基づき説明する。
図1から図3は本発明の実施形態を示し、図1は可撓性シートを用いたスクリーン装置の斜視図、図2は可撓性シートの芯材を構成する織物の要部拡大図、図3はこの織物の織り組織を示し、図3(a)は織り組織の部分図、図3(b)は織り組織の繰り返し単位を示す組織図である。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an embodiment of the present invention, FIG. 1 is a perspective view of a screen device using a flexible sheet, and FIG. 2 is an enlarged view of a main part of a fabric constituting a core material of the flexible sheet. FIG. 3 shows a woven structure of the woven fabric, FIG. 3 (a) is a partial view of the woven structure, and FIG. 3 (b) is a structural diagram showing a repeating unit of the woven structure.

図1に示すように、このスクリーン装置(1)は、平面展開可能な可撓性シート(2)と、この可撓性シート(2)を不使用時に巻取り収納できる収納装置(3)と、可撓性シート(2)の下端縁に付設された棒状の錘部材(4)とからなり、収納装置(3)から垂下されて平面状に展開された上記の可撓性シート(2)に、図外のプロジェクターから投射された画像(5)を映し出すようにしてある。   As shown in FIG. 1, the screen device (1) includes a flexible sheet (2) that can be flattened, and a storage device (3) that can wind up and store the flexible sheet (2) when not in use. The flexible sheet (2) comprises a rod-shaped weight member (4) attached to the lower edge of the flexible sheet (2), and is suspended from the storage device (3) and developed in a planar shape. In addition, an image (5) projected from a projector (not shown) is projected.

上記の可撓性シート(2)は、厚さが0.05乃至0.20mmの織物(6)を芯材として、この織物(6)の表面に塩化ビニル樹脂などの合成樹脂により、0.05乃至0.5mmの厚みでコーティング層(7)を形成してある。このコーティング層(7)の表面には、必要に応じてエンボス加工を施してある。   The flexible sheet (2) has a woven fabric (6) having a thickness of 0.05 to 0.20 mm as a core material, and the surface of the woven fabric (6) is made from a synthetic resin such as a vinyl chloride resin to a thickness of 0.06. A coating layer (7) is formed with a thickness of 05 to 0.5 mm. The surface of the coating layer (7) is embossed as necessary.

図2に示すように、上記の芯材を構成する織物(6)は、経糸(8)と緯糸(9)とを互いに交差させて織成してあり、これらの織糸(10)には、例えば20乃至140texのガラス長繊維が用いてある。
なお、上記の織物(6)やコーティング層(7)の厚さ、コーティング層(7)の材質、織糸(10)の材質や太さ等は、実施形態として例示したものであって、本発明はこの実施形態のものに限定されない。
As shown in FIG. 2, the woven fabric (6) constituting the core material is woven by crossing the warp yarn (8) and the weft yarn (9), and these woven yarns (10) include, for example, Glass long fibers of 20 to 140 tex are used.
The thickness of the woven fabric (6) and the coating layer (7), the material of the coating layer (7), the material and the thickness of the woven yarn (10), etc. are exemplified in the embodiment. The invention is not limited to this embodiment.

図2と図3に示すように、上記の織物(6)の織り組織は、4枚破れ斜紋(トルコ朱子)に形成してある。これにより、上記の画像(5)を受ける表面側では、織糸(10)のうちの経糸(8)の浮部(11)が、隣接する縦方向と横方向には連続せず、且つ、斜め方向には断続的に並んでおり、しかも、隣接する斜め方向ではこの経糸(8)の浮部(11)の連続数を異ならせてある。   As shown in FIGS. 2 and 3, the woven structure of the woven fabric (6) is broken into four and formed into a diagonal pattern (Turkish vermilion). Thereby, on the surface side that receives the image (5), the floating portion (11) of the warp yarn (8) of the woven yarn (10) is not continuous in the adjacent vertical and horizontal directions, and The warp yarns are arranged intermittently in the diagonal direction, and the number of continuous floating portions (11) of the warp yarn (8) is different in the adjacent diagonal direction.

即ち、図3(a)に示すように、この織り組織は経糸(8)の浮部(11)を斜め方向に2つ連続させて、これを断続的に配置してあるが、その連続する斜め方向(綾線)は、交互に向きを変えた破れ斜紋にしてある。このため、その浮部(11)の斜め方向の並びは、隣接する斜め方向の並びと浮部(11)の連続数が互いに異なる。具体的には、ある斜め方向の並びは、経糸(8)の浮部(11)が斜め方向に、2つ置きに2つずつ連続して配置され、その隣りの斜め方向の並びでは3つ置きに1つずつ配置され、さらにその隣りの斜め方向の並びでは、浮部が全く形成されない。
上記の織り組織は、図3(b)に示すように、繰り返し単位が経糸4本×緯糸4本からなり、4枚ヘルドを用いて簡単に製織される。
That is, as shown in FIG. 3 (a), this weave structure has two floating portions (11) of warp yarns (8) arranged in an oblique direction and arranged intermittently. The diagonal direction (the twill line) is a torn oblique pattern with the direction changed alternately. For this reason, the arrangement of the floating portions (11) in the oblique direction is different from the arrangement in the adjacent oblique directions and the number of consecutive floating portions (11). Specifically, as for the arrangement in a certain diagonal direction, the floating portions (11) of the warp yarns (8) are arranged in the diagonal direction in succession every two, and three in the adjacent diagonal direction. One by one is arranged, and the floating part is not formed at all in the adjacent diagonal arrangement.
As shown in FIG. 3 (b), the above woven structure is composed of 4 warps × 4 wefts and is easily woven using 4 healds.

次に、上記の織物(6)の性能を確認するため、ガラス長繊維を用い、織糸の太さと織り密度を変化させて4枚破れ斜紋の織物を製織し、これにデジタル画像を投射した場合の干渉縞の発生状態を、ガラス長繊維で平織にした従来の織物と比較しながら測定した。   Next, in order to confirm the performance of the above-mentioned woven fabric (6), a long glass fiber was used to change the thickness of the woven yarn and the weaving density, and a four-sheet teared woven fabric was woven, and a digital image was projected onto this. The state of occurrence of interference fringes was measured in comparison with a conventional woven fabric made of plain glass fibers.

Two woven fabrics were arranged in succession, and these were arranged intermittently, and the continuous oblique direction (twill line) was a woven structure in which the directions were alternately changed.

また、比較例に用いた織糸の太さ、織り密度、及び織物の質量は、次の通りである。
(比較例1)

(比較例4)
織糸の太さは経糸33.7tex×緯糸33.7tex、織り密度は経糸60本/25mm×緯糸50本/25mmとした。織物の質量は、148.3g/m2であった。
(Comparative Example 3)
The thickness of the weaving yarn was 33.7tex warp × 33.7tex weft, and the weaving density was 60 warps / 25mm × 35 wefts / 25mm. The mass of the woven fabric was 128.1 g / m 2 .
(Comparative Example 4)
The thickness of the weaving yarn was 33.7tex warp x 33.7tex weft, and the weaving density was 60 warps / 25mm x 50 wefts / 25mm. The mass of the woven fabric was 148.3 g / m 2 .

測定方法は、前記のコーティング層(7)を形成していない状態の織物にプロジェクターから画像を投射し、その画像の大きさを60乃至120インチに変えた際の、それぞれの画像での干渉縞の発生の有無を確認した。これらの測定結果を図4の対比表に示す。   The measurement method is to project an image from a projector onto a fabric in which the coating layer (7) is not formed, and change the size of the image to 60 to 120 inches. Interference fringes in each image The presence or absence of occurrence was confirmed. These measurement results are shown in the comparison table of FIG.

上記の対比表から明らかなように、本発明の実施例1〜5では、いずれの場合も、画像の各サイズにおいて干渉縞の発生が無いか、発生しても微かであって画像への影響は殆どなく、画質を低下させることはなかった。なお、実施例1では画像の各サイズにおいて干渉縞が全く生じなかったのに対し、その裏面を用いた実施例5では干渉縞が微かに発生したことから、前記の縦方向と横方向に連続しない浮部(図3において黒く塗りつぶした部分)は、緯糸よりも経糸で構成すると好ましいことが明らかとなった。   As is clear from the above comparison table, in each of the first to fifth embodiments of the present invention, there is no interference fringe in each size of the image, or the occurrence of interference fringes is slight, and the influence on the image. There was almost no decrease in image quality. In Example 1, no interference fringes were generated at each size of the image, whereas in Example 5 using the back surface, interference fringes were slightly generated. Therefore, the vertical and horizontal directions were continuous. It has become clear that the floating portion (the portion painted black in FIG. 3) that is not formed is preferably made of warp rather than weft.

これに対し、織り組織を平織とした各比較例にあっては、いずれの場合も、画像の大きさを変化させた際に、いずれかの画像のサイズにおいてはっきりとした干渉縞が発生し、画質を低下させた。   On the other hand, in each comparative example in which the woven structure is a plain weave, in any case, when the size of the image is changed, a clear interference fringe occurs in the size of any image, Reduced image quality.

なお、上記の実施形態や実施例で説明した織物と可撓性シートは、本発明の技術的思想を具体化するために例示したものであり、使用する繊維の材質や太さ、織り密度、織り組織等を、この実施形態に限定するものではなく、本発明の特許請求の範囲内において種々の変更を加え得るものである。   In addition, the fabric and flexible sheet described in the above embodiment and examples are examples for embodying the technical idea of the present invention, and the material and thickness of the fibers used, the weave density, The weaving structure and the like are not limited to this embodiment, and various modifications can be made within the scope of the claims of the present invention.
