Description
オフィスや住宅などで使用するブラインド用素材に関する。 It relates to blind materials used in offices and homes.
近年、オフィスや住宅では省エネルギーの観点から、夏場の直射日光から住宅などの内部温度の上昇を防いだり、冬場の内部温度の低下を防ぐなどのためにブラインドを使用することの重要性が増している。さらに、落ち着いた雰囲気をかもし出す外観を有するブラインド素材として和紙調外観が意匠面でも注目されている。 In recent years, it has become more important to use blinds in offices and homes to save energy from direct sunlight in summer in order to prevent the rise of internal temperature in homes, etc., and to prevent a decrease in internal temperature in winter. Yes. Furthermore, a Japanese paper-like appearance has been attracting attention as a design as a blind material having an appearance that creates a calm atmosphere.
部分的に熱圧着される短繊維不織布とスパンボンドとからなるシートを使用するブラインドが開示されている（特許文献１）。短繊維不織布とスパンボンドとを積層するため、透かして見ると短繊維不織布とスパンボンド両方の素材が合わさった外観となり、和紙調の落ち着いた外観をかもし出すことが難しい。 A blind using a sheet made of a short fiber nonwoven fabric and a spunbond which are partially thermocompression bonded is disclosed (Patent Document 1). Since the short fiber nonwoven fabric and the spunbond are laminated, when viewed through, the appearance of both the short fiber nonwoven fabric and the spunbond is combined, and it is difficult to bring out a calm appearance of Japanese paper.
ガラス繊維を織ったガラスクロスの両面に不織布を積層したブラインド用素材が開示されている（特許文献２）。芯材のガラスクロスの両側に不織布層が配置されるため、透かして見ると２つの不織布層越しの外観で和紙調の落ち着いた外観をかもし出すに不十分である上に、合成繊維による不織布層が外面になるため表面強度に乏しい。 A blind material in which a nonwoven fabric is laminated on both surfaces of a glass cloth woven with glass fibers is disclosed (Patent Document 2). Since the nonwoven fabric layers are arranged on both sides of the glass cloth of the core material, when viewed through, it is not sufficient to bring out the appearance of the Japanese paper-like appearance with the appearance over the two nonwoven fabric layers. Since it is an outer surface, it has poor surface strength.
有機繊維不織布の両側にガラス繊維不織布を積層したブラインド用素材が開示されている（特許文献３）。３層の不織布層を使用するため光が透過しにくく、透かして見たときに落ち着いた和紙特有の外観を保持するのが難しく、ガラス繊維の強度などを得るために樹脂含浸などをおこなうため、柔らかさに欠けるなどの難点がある。 A blind material in which glass fiber nonwoven fabrics are laminated on both sides of an organic fiber nonwoven fabric is disclosed (Patent Document 3). Because it uses three layers of non-woven fabric, it is difficult to transmit light, it is difficult to maintain a calm Japanese paper appearance when viewed through the water, and because resin impregnation is performed to obtain the strength of glass fiber, etc. There are difficulties such as lack of softness.
本発明は、上記問題点に鑑み、光が透過したときに和紙調の視認性に優れた和紙調外観を有するとともに、光の反射に対しても和紙調の意匠を持ち、柔らかく、優れた形状保持性、防炎性に優れたブラインド用素材を提供することを課題とする。 In view of the above problems, the present invention has a Japanese paper-like appearance that is excellent in Japanese paper-like visibility when light is transmitted, has a Japanese-paper-like design against light reflection, is soft, and has an excellent shape. An object of the present invention is to provide a blind material excellent in retention and flameproofness.
本発明者らは、課題を解決するために鋭意研究した結果優れた発明となることを見出した。 The present inventors have found that the present invention is an excellent invention as a result of intensive studies to solve the problems.
本発明においては、請求項１のブラインド用素材は、少なくとも、合成樹脂層／和紙調外観層／合成樹脂層からなり、和紙調外観層として不織布を使用し、不織布がガラス繊維からなり、合成樹脂層として塩化ビニル樹脂を使用し、ＪＩＳ−Ｋ７１０５における、平行光線透過率が５％から４５％であり、ヘイズ度が６０％から９５％であることを特徴としている。請求項２の発明は、和紙調外観層が、目付量１５−８０ｇ／ｍ２、ＪＩＳ−Ｐ８１１３による引張強度４５−４０５Ｎ／５０ｍｍ、破断時の伸び率０−２．０％のすべてを満足することを特徴としており、さらに請求項３では、ＪＩＳ−Ｌ１０９６（４５度カンチレバー法）による剛軟度が２０ｍｍから３５０ｍｍであることを特徴としている。In the present invention, the blind material of claim 1 is composed of at least a synthetic resin layer / Japanese paper-like appearance layer / synthetic resin layer, a non-woven fabric is used as the Japanese paper-like appearance layer, and the non-woven fabric is made of glass fiber. A vinyl chloride resin is used as the layer, and the parallel light transmittance according to JIS-K7105 is 5% to 45%, and the haze degree is 60% to 95%. In the invention of claim 2, the Japanese paper-like appearance layer satisfies all of the basis weight 15-80 g / m 2 , tensile strength 45-405 N / 50 mm according to JIS-P8113, and elongation at break 0-2.0%. Further, in claim 3, the bending resistance according to JIS-L1096 (45 degree cantilever method) is 20 mm to 350 mm.
和紙調外観層の両側に適度な光を透過する合成樹脂層を設けることにより、透過光に対してぎらつきがなく柔らかい光による落ち着きを与える。また、反射光に対しても優れた和紙調の意匠性を視認することができる。さらに、不織布などによる和紙調外観層が一層のみのため、この層の持つ外観そのものを保持することもでき、防炎性や形状保持性に優れたブラインド用素材を提供することができる。 By providing a synthetic resin layer that transmits appropriate light on both sides of the Japanese paper-like appearance layer, there is no glare with respect to the transmitted light, and calmness by soft light is given. In addition, it is possible to visually recognize an excellent Japanese paper-like design with respect to reflected light. Furthermore, since there is only a single layer of Japanese paper-like appearance with a nonwoven fabric or the like, the appearance itself of this layer can be maintained, and a blind material excellent in flameproofness and shape retention can be provided.
本発明のブラインド用素材は、少なくとも合成樹脂層／和紙調外観層／合成樹脂層から構成されている。 The blind material of the present invention is composed of at least a synthetic resin layer / Japanese paper appearance layer / synthetic resin layer.
和紙調外観層は、紙を漉いたような意匠外観を有する層で、短繊維からなる和紙や不織布などを適宜使用して作成することができる。合成樹脂層との貼り合せなどの加工性や工業生産性を考えると、不織布の使用が好ましい。不織布としては、ポリエステルやポリオレフィンやポリイミドやポリウレタンやガラスなどからなる繊維を単独もしくは混合して使用することができ、繊維の繊維径や繊維長は所望する外観に合わせて選択することができる。目付量は光を透過したときの意匠外観や光線の透過性などとの関係で１５−８０ｇ／ｍ２が好ましい。また、不織布にポリエステル樹脂やアクリル樹脂やフェノール樹脂やポバール樹脂やエポキシ樹脂などの加工を行い、不織布繊維の表面や端面からの毛羽立ち防止や、合成樹脂層との接着性を向上させてもよい。不織布の中でも防炎性と寸法安定性を考えるとガラス繊維を使用した不織布の使用がより好ましい。The Japanese paper-like appearance layer is a layer having a design appearance that looks like paper, and can be created by appropriately using Japanese paper or nonwoven fabric made of short fibers. Considering processability such as bonding with a synthetic resin layer and industrial productivity, use of a nonwoven fabric is preferable. As the nonwoven fabric, fibers made of polyester, polyolefin, polyimide, polyurethane, glass or the like can be used alone or in combination, and the fiber diameter and fiber length of the fiber can be selected according to the desired appearance. The weight per unit area is preferably 15-80 g / m 2 in relation to the appearance of the design when light is transmitted and the light transmittance. Further, the nonwoven fabric may be processed with a polyester resin, an acrylic resin, a phenol resin, a poval resin, an epoxy resin, or the like to prevent fuzz from the surface or end face of the nonwoven fabric and to improve the adhesion to the synthetic resin layer. Among the nonwoven fabrics, it is more preferable to use a nonwoven fabric using glass fibers in view of flameproofing and dimensional stability.
和紙調外観層はＪＩＳ−Ｐ８１１３による引張強度が４５−４０５Ｎ／５０ｍｍ、破断時の伸び率が０−２．０％の範囲であることが望ましい。引張強度が４５Ｎ／５０ｍｍより小さく破断時の伸び率が２．０％より大きいと、合成樹脂層との一体化に際して、破断や伸びたことによる和紙調外観層の部分的抜けなどの問題が発生して加工が難しくなり、形状保持性も低下する。一方、引張強度が４０５Ｎ／５０ｍｍより大きくなると、合成樹脂層との一体化はできるものの、和紙調外観層自体の厚みが増加する傾向にあるため、特に光を透過したときの和紙調の意匠外観を有することが難しいため望ましくない。合成樹脂層との一体化など加工工程で張力がかかっても、出来上がったブラインド用素材がカールなど発生せず優れた形状保持性を得るためには、和紙調外観層自体の破断時の伸び率はできるだけ小さく０％であるのが最も望ましい。 The Japanese paper-like appearance layer preferably has a tensile strength of 45 to 405 N / 50 mm according to JIS-P8113 and an elongation at break of 0 to 2.0%. If the tensile strength is less than 45 N / 50 mm and the elongation at break is greater than 2.0%, problems such as partial breakage of the Japanese paper-like appearance layer due to breakage or elongation occur during integration with the synthetic resin layer. As a result, the processing becomes difficult and the shape retainability also decreases. On the other hand, when the tensile strength is greater than 405 N / 50 mm, although it can be integrated with the synthetic resin layer, the thickness of the Japanese paper-like appearance layer itself tends to increase. It is not desirable because it is difficult to have Even if tension is applied in the processing process such as integration with the synthetic resin layer, the finished material for blinds does not generate curl, etc. In order to obtain excellent shape retention, the elongation at break of the Japanese paper appearance layer itself Most preferably, is as small as possible and 0%.
合成樹脂層に使用する合成樹脂としては、ポリウレタンやポリエステルや塩化ビニルやエチレン・酢酸ビニル共重合体など一般の合成樹脂を適宜使用できる。防炎性や加工のし易さから塩化ビニルの使用が好ましい。光の透過性に影響を及ぼさない範囲内で必要に応じて、可塑剤、安定剤、着色剤、充填剤などの添加剤を添加することができる。 As a synthetic resin used for the synthetic resin layer, general synthetic resins such as polyurethane, polyester, vinyl chloride, ethylene / vinyl acetate copolymer can be appropriately used. The use of vinyl chloride is preferred from the viewpoint of flame resistance and ease of processing. Additives such as plasticizers, stabilizers, colorants, fillers and the like can be added as necessary within a range that does not affect the light transmittance.
合成樹脂層の上面には、表面の光沢を低下などさせるためのつや消し剤の塗布や、滑り性や耐ブロッキング性を保持させるための塗料塗布などの表面処理加工を行ってもよい。 The upper surface of the synthetic resin layer may be subjected to a surface treatment such as application of a matting agent for reducing the gloss of the surface or coating for maintaining slipperiness or blocking resistance.
また、和紙調外観層や合成樹脂層を着色したり印刷層を設けたりして外観に変化を持たせ新たな意匠性を出してもよい。 In addition, the appearance may be changed by coloring a Japanese paper-like appearance layer or a synthetic resin layer or by providing a printing layer so as to give a new design.
合成樹脂層は、コーティング加工やラミネート加工やカレンダー加工や押出加工など公知の加工方法を適宜選択することにより作成することができる。 The synthetic resin layer can be prepared by appropriately selecting a known processing method such as coating, laminating, calendaring, or extrusion.
和紙調外観層として、織布より引張強度が小さく加工時の加熱により伸びやすい不織布を使用するため、合成樹脂層との一体化にあたっては加工条件に留意する必要があり、特にカレンダー加工においては、加工後のブラインド用素材の形状保持性を確保するためにも、合成樹脂層の加工途上のガイドロールへの接触をできる限り避けて抵抗を低減させると共に、変速できるロールの速度は同速とするのが好ましい。 As a Japanese paper-like appearance layer, it is necessary to pay attention to the processing conditions when integrating with the synthetic resin layer because it uses a nonwoven fabric that has a lower tensile strength than a woven fabric and is easily stretched by heating during processing. In order to ensure the shape retention of the blind material after processing, the resistance of the synthetic resin layer is reduced as much as possible by avoiding contact with the guide roll in the process of processing, and the speed of the variable speed roll is the same speed. Is preferred.
特に、カレンダー加工における優れた条件を試行錯誤により見出したことにより、引張強度が小さく加工時の加熱により伸びやすい不織布を使用しても形状保持性に優れたブラインド用素材の製造が可能になったものである。 In particular, the discovery of excellent conditions in calendering through trial and error has made it possible to produce blind materials with excellent shape retention even when using non-woven fabric that has low tensile strength and is easily stretched by heating during processing. Is.
本発明のブラインド用素材は、用途に合わせてタテ型、ヨコ型、ロールスクリーン型など各種形態のブラインドに対応することができ、形状保持性に優れるため、特にタテ型ブラインドに使用するとブラインドとしての全体外観や意匠性に優れたものとなる。 The blind material of the present invention can correspond to various types of blinds such as a vertical type, a horizontal type, and a roll screen type according to the application, and has excellent shape retention. It will be excellent in overall appearance and design.
本発明によるブラインド用素材のＪＩＳ−Ｋ７１０５（１９８１）による平行光線透過率は５−４５％の範囲が好ましい。５％より小さくなるとブラインド用素材を介した視認性が殆ど失われ和紙調外観をかもし出すことが困難となり、４５％より大きくなると透過光線による眩しさにより、せっかくの和紙調の意匠性が損なわれるという問題がある。 The parallel light transmittance according to JIS-K7105 (1981) of the blind material according to the present invention is preferably in the range of 5-45%. If it is less than 5%, the visibility through the blind material is almost lost and it becomes difficult to bring out a Japanese paper-like appearance. If it is more than 45%, the design of the Japanese paper style is impaired due to glare caused by transmitted light. There's a problem.
ＪＩＳ−Ｋ７１０５（１９８１）によるヘイズ度は６０−９５％が好ましい。６０％より小さいと光の透過によりまぶしさなどにより和紙調の意匠性が損なわれ、９５％より大きいと光の拡散などによりブラインド用素材を介した視認性が失われるという問題がある。 The haze degree according to JIS-K7105 (1981) is preferably 60-95%. If it is less than 60%, the design of a Japanese paper tone is impaired due to glare due to light transmission, and if it is more than 95%, the visibility through the blind material is lost due to light diffusion.
本発明のブラインド用素材の背景に標準白色板を用いた場合と標準黒色板を用いた場合との色差ΔＥを色差計で測定し、和紙調外観視認性とした。ΔＥは１５から４５が好ましい。ΔＥが１５より小さいと、ブラインド用素材の隠蔽性は優れるものの屋外が暗い夜間の室内で、室内照明によりブラインド用素材を眺めたとき、和紙調外観層の密度が密のため繊維が部分的にちりばめられたような和紙調外観の意匠性を視認することができず、本発明の目的である和紙調外観について不十分である。ΔＥが４５より大きくなると隠蔽性に劣り和紙調外観層の密度が極めて粗い状態のため和紙のイメージが得られない。背景に標準白色板を用いた場合と標準黒色板を用いた場合との色差ΔＥを、適度な範囲に保持することにより夜間など室内の光でブラインド用素材を眺めたときに、優れた和紙調外観がかもし出される。 The color difference ΔE between the case of using the standard white plate and the case of using the standard black plate as the background of the blind material of the present invention was measured with a color difference meter to obtain Japanese paper-like appearance visibility. ΔE is preferably 15 to 45. If the ΔE is less than 15, the blind material is excellent in concealment, but the outdoor material is dark and the blind material is viewed by indoor lighting. The design of a Japanese paper-like appearance that is interspersed cannot be visually recognized, and the Japanese paper-like appearance that is the object of the present invention is insufficient. If ΔE is greater than 45, the concealability is inferior and the density of the Japanese paper-like appearance layer is so coarse that a Japanese paper image cannot be obtained. By maintaining the color difference ΔE between the case of using a standard white plate and the case of using a standard black plate in an appropriate range, an excellent Japanese paper tone can be obtained when viewing the blind material with indoor light such as at night. Appearance is raised.
本発明のブラインド用素材においては、意匠性を保持するためには平行光線透過率やヘイズ度や和紙調外観視認性を示す色差ΔＥなどは重要な要素である。 In the blind material of the present invention, in order to maintain the design, the parallel light transmittance, the haze degree, the color difference ΔE indicating the Japanese paper-like appearance visibility, and the like are important factors.
ＪＩＳ−Ｌ１０９６（４５度カンチレバー法）による剛軟度は２０ｍｍから３５０ｍｍが好ましい。２０ｍｍより小さくなるとブラインド用素材としての腰がなくタテ型、ヨコ型、ロールスクリーン型など用途に合せた形態を保持するのが難しい。一方、３５０ｍｍより大きくなるとブラインド用素材をブラインドとして作成するにあたって加工がしにくくなると共に、ブラインドとして巻取りにくい、収納しにくいなどの問題が生じる。 The bending resistance according to JIS-L1096 (45 degree cantilever method) is preferably 20 mm to 350 mm. If it is smaller than 20 mm, there is no waist as a material for blinds, and it is difficult to maintain a shape suitable for use such as a vertical type, a horizontal type, and a roll screen type. On the other hand, if the thickness is larger than 350 mm, it is difficult to process the blind material as a blind, and problems such as difficulty in winding up and storage as a blind occur.
ブラインド用素材、その中でもとりわけタテ型として使用する場合、タテ長のブラインド用素材がヨコ方向にカールして丸まらないように形状保持することは重要な特性である。この形状保持性能としてブラインド用素材のカール状態を目視にて観察する。目視によりカールの発生がほとんど見られず見栄えに問題ないと判断される必要があり、タテ型ブラインドとして使用した時にカールが発生すると見栄えが悪くなり、極度にカールの度合が大きく丸まると、窓際などで外からの光をさえぎる効果にも影響を与え商品としての体もなさなくなる。 When used as a blind material, and in particular, as a vertical type, it is an important characteristic to maintain the shape of the vertical blind material so that it does not curl in a horizontal direction and curl. As this shape retention performance, the curl state of the blind material is visually observed. It is necessary to judge that there is almost no curling by visual inspection and that there is no problem with the appearance, and when it is used as a vertical blind, the appearance will deteriorate and if the curl degree is extremely large and rounded, the window side etc. It also affects the effect of blocking the light from the outside and the body as a product is lost.
本発明のブラインド用素材は、ＪＩＳ−Ｌ１０９１ Ａ−１法 による防炎性能を保持していることが好ましい。 It is preferable that the blind material of the present invention retains the flameproof performance according to JIS-L1091 A-1.
また、ブラインド用素材のふき取りによる掃除やブラインド用素材同士が擦れ合うことによる摩擦で素材表面に剥れや素材の毛羽立ちなどが発生しないことも重要な要素である。ＪＩＳ−Ｌ０８４９の摩擦試験機ＩＩ形（学振式）で金巾３号を摩擦子として用い、荷重２００ｇで１００往復擦ったときのブラインド用素材（被摩擦試験片）の外観を目視にて判定を行い、摩擦子の金巾３号や被摩擦試験片にも異常が見られず、ブラインド用素材表面に剥れや素材の毛羽立ちなどの発生などの外観異常もなく実用可能である必要がある。 Another important factor is that the surface of the material does not peel off or become fuzzy due to the cleaning by wiping the material for the blind or the friction caused by the friction between the materials for the blind. Using JIS-L0849 Friction Tester Type II (Gakushin Type), using gold No. 3 as a friction element, visually determine the appearance of the blind material (rubbing specimen) when rubbing 100 reciprocations with a load of 200 g. No abnormalities are observed in the gold width No. 3 of the friction element or the rubbed specimen, and it should be practical without any abnormal appearance such as peeling on the blind material surface or occurrence of fluffing of the material.
このように、本発明において、平行光線透過率やヘイズ度や色差や剛軟度や形状保持性能を特定の範囲とすることを見出したことにより、初めて、優れた和紙調外観を有するブラインド用素材を達成するにいたった。 Thus, in the present invention, for the first time, by finding that the parallel light transmittance, haze degree, color difference, bending resistance, and shape retention performance are in a specific range, a blind material having an excellent Japanese paper-like appearance for the first time. To achieve.

It was shown to. This corresponds to a situation where the material for blinds of the present invention is viewed indoors in the daytime, and a Japanese paper-like appearance emerges. On the other hand, FIG. 2 is an enlarged view of the appearance of the blind material of the present invention in which the back surface is black and the light is reflected. It was shown to. This corresponds to a situation in which the blind material of the present invention is viewed with indoor lighting at night and shows a Japanese paper-like appearance with respect to reflected light.

Therefore, sampling was performed at 9 points, and the average values were taken as the parallel light transmittance and haze degree. .
（色差ΔＥ）
クラボウ社製ＣＯＬＯＲ−７Ｘを使用し、白色又は黒色の標準板にブラインド用素材をあて、白い背景の場合と黒い背景の場合との色差ΔＥを測定する。色差ΔＥが小さいほど和紙調外観層の繊維密度が密であり白もしくは黒の背景色の影響を受けにくく隠蔽性に優れる。一方、ΔＥが大きいと和紙調外観層の繊維密度が粗であり白もしくは黒の背景色の影響を受けて隠蔽性に欠ける。反射光によるすぐれた和紙調外観を視認できる意匠性を持つには、適度な和紙調外観反射視認性（色差ΔＥ）を保持する必要がある。色差ΔＥは和紙調外観層の繊維密度などにより影響を受けサンプリング位置によってばらつきが考えられるため、９点でサンプリングを行い測定しその平均値を和紙調外観反射視認性を示す色差ΔＥとした。(Color difference ΔE)
Using COLOR-7X manufactured by Kurabo Industries, a blind material is applied to a white or black standard plate, and the color difference ΔE between the white background and the black background is measured. The smaller the color difference ΔE is, the denser the fiber density of the Japanese paper-like appearance layer is, and it is less affected by the white or black background color and has better concealment. On the other hand, when ΔE is large, the fiber density of the Japanese paper-like appearance layer is rough, and it is affected by the background color of white or black and lacks concealment. In order to have a design property capable of visually recognizing an excellent Japanese paper-like appearance by reflected light, it is necessary to maintain an appropriate Japanese paper-like appearance reflection visibility (color difference ΔE). Since the color difference ΔE is influenced by the fiber density of the Japanese paper-like appearance layer and varies depending on the sampling position, sampling was performed at 9 points, and the average value was defined as the color difference ΔE indicating the Japanese paper-like appearance reflection visibility.

表１に示したように、本発明による実施例は、ブラインド用素材としての性能を有するものである。その中でも実施例１−４は、平行光線透過率、ヘイズ度、和紙調外観反射視認性（色差ΔＥ）にバランスのとれたものであり、和紙調外観を有するブラインド用素材として透過光及び反射光に対して優れた性能を保持するものである。さらに、防炎性、耐摩耗性、剛軟度、形状保持性についても優れた品質を保持しているため、本発明のブラインド用素材を用いることにより優れたブラインドを作成できる。また、使用する和紙調外観層の引張強度と破断時の伸び率により合成樹脂層との一体化にあたって問題なく加工ができ、性能を保持できる。 As shown in Table 1, the embodiment according to the present invention has performance as a blind material. Among them, Example 1-4 is balanced in parallel light transmittance, haze degree, Japanese paper-like appearance reflection visibility (color difference ΔE), and transmitted light and reflected light as a blind material having a Japanese paper-like appearance. It maintains excellent performance. Furthermore, since excellent quality is maintained with respect to flame resistance, wear resistance, bending resistance, and shape retention, an excellent blind can be produced by using the blind material of the present invention. Moreover, it can process without a problem in integration with a synthetic resin layer by the tensile strength of the Japanese paper-like appearance layer to be used and the elongation at break, and the performance can be maintained.
参考例１は、和紙調外観層として使用するガラス繊維不織布の目付が小さいため平行光線透過率が大きくなり、ブラインド素材として使用することは可能であるが、太陽光を透過してブラインド用素材を眺めるとぎらつき感がある。また、参考例２のように和紙調外観層としてポリエステル繊維を使用すると破断時の伸び率が大きく、ブラインド用素材として加工することはできるものの、防炎性や形状保持性に難点もある。実施例５のように剛軟度が大きくなると、ブラインド用素材として使用するにあたって特にロールスクリーン型では加工や巻取りや収納に難点がある。 In Reference Example 1 , since the basis weight of the glass fiber nonwoven fabric used as the Japanese paper-like appearance layer is small, the parallel light transmittance is large, and it can be used as a blind material. There is a feeling of glare when you look at it. In addition, when polyester fibers are used as a Japanese paper-like appearance layer as in Reference Example 2 , the elongation at break is large and can be processed as a blind material, but there are also problems in flameproofness and shape retention. When the bending resistance increases as in the fifth embodiment, the roll screen type has a difficulty in processing, winding and storage when used as a blind material.
合成樹脂層の両面にガラス繊維不織布を和紙調外観層として一体化させた構成体である比較例１においては、表面の耐摩耗性に乏しく、ブラインド用素材として使用するには表面強度の面で不十分なばかりでなく、和紙調外観層が２層になるため、光の透過や反射時に和紙調外観の意匠をかもし出すことができない。したがって本発明実施例のように和紙調外観層を１層として、その両面に合成樹脂層を設けることが最良の形態である。In Comparative Example 1 in which a glass fiber nonwoven fabric is integrated as a Japanese paper-like appearance layer on both sides of the synthetic resin layer, the surface wear resistance is poor, and in terms of surface strength to use as a blind material. Not only is it insufficient, but the Japanese paper-like appearance layer has two layers, so that a design with a Japanese paper-like appearance cannot be produced when light is transmitted or reflected. Therefore, the best mode is to provide a Japanese paper-like appearance layer as one layer and provide a synthetic resin layer on both sides as in the embodiment of the present invention.
本発明による和紙調外観層を一層とするブラインド用素材、その中でも特に実施例１−４は、光線の透過に対して適度な透過率を、反射に対しては適度な色差ΔＥを保持しているため、和紙調外観として優れた意匠性を持つとともに、防炎性や表面摩擦強度や剛軟度や形状保持性に優れるため、ブラインド用素材としてバランスのとれた製品化が可能である。特に、オフィスや住宅での省エネルギーが重要視されるなかで、夏場の直射日光による内部温度の上昇を防いだり、冬場の内部温度の低下を防止する上でも重要な役割を果たすもので、単にブラインド用素材としての機能を保持するばかりでなく、優れた和紙調外観による癒しの効果により精神的な落ちつきまでも得ることができる。 The blind material having a Japanese paper-like appearance layer according to the present invention, in particular, Example 1-4, in particular, has an appropriate transmittance for light transmission and an appropriate color difference ΔE for reflection. Therefore, it has excellent design characteristics as a Japanese paper-like appearance, and is excellent in flameproofness, surface friction strength, bending resistance, and shape retention, so that it can be made into a balanced product as a blind material. In particular, energy saving in offices and homes is important, and it plays an important role in preventing the rise of internal temperature due to direct sunlight in summer and preventing the fall of internal temperature in winter. In addition to maintaining the function as a material for use, it is possible to obtain mental relaxation due to the healing effect of an excellent Japanese paper-like appearance.
このように本発明のブラインド用素材は、省エネルギーや精神的な癒し効果を兼ね備えた素材として、産業界への寄与は大きいものである。 Thus, the blind material of the present invention contributes greatly to the industrial world as a material having both energy saving and mental healing effects.
