Abstract
Description
本発明は塩化ビニル壁紙等に使用される壁紙用裏打ち紙に関する。 The present invention relates to a backing paper for wallpaper used for vinyl chloride wallpaper and the like.
壁紙は、一般住居、ホテル、病院等において室内の美麗化のために、長期間壁に貼付される。壁紙にはビニル壁紙、オレフィン壁紙、織物壁紙、紙壁紙、無機質壁紙等があるが、これらの壁紙は、ビニル層、オレフィン層、織物層、紙層、無機質層等の化粧層と、該化粧層を保持するための裏打ち紙により構成されている。 The wallpaper is affixed to the wall for a long period of time in order to beautify the room in general houses, hotels, hospitals, and the like. The wallpaper includes a vinyl wallpaper, an olefin wallpaper, a fabric wallpaper, a paper wallpaper, an inorganic wallpaper, and the like. These wallpapers include a decorative layer such as a vinyl layer, an olefin layer, a fabric layer, a paper layer, an inorganic layer, and the decorative layer. It is comprised by the backing paper for hold | maintaining.
これらの壁紙は施工時、澱粉や酢酸ビニル樹脂系の水系の糊によって壁に貼合されるが、糊付け工程で裏打ち紙が糊中の水分を吸収するため、壁紙が柔らかくなったり、裏打ち紙が水分増加により伸びたりすることがある。これらが原因となって、壁紙がカールし、壁への貼付作業が困難になったり、貼付後捲れが発生し易くなったりする等の問題が生じた。更に、糊が乾燥すると裏打ち紙が収縮するために、隣接して貼り合せた壁紙同士の繋ぎ目部分に隙間（目開き）が生じ、施工後の意匠性を損なうなどの問題があった。 These wallpapers are glued to the wall with starch or vinyl acetate resin water-based glue during construction, but the backing paper absorbs moisture in the glue during the gluing process, so the wallpaper becomes soft or the backing paper May increase due to increased moisture. For these reasons, the wallpaper is curled, making it difficult to apply to the wall, and causing problems such as the tendency of wrinkling after application. Furthermore, since the backing paper contracts when the glue dries, there is a problem in that a gap (opening) is generated at the joint portion between the adjacently bonded wallpapers, and the design properties after construction are impaired.
裏打ち紙の寸法安定性の改善として、水分による伸縮の少ないガラス繊維等の無機系繊維を配合した裏打ち紙（特許文献１〜５）、平均粒子径が８μｍ以上１５０μｍ以下であるマイカ（雲母）を配合した裏打ち紙（特許文献６）が開示されている。 As an improvement in the dimensional stability of the backing paper, a backing paper (Patent Documents 1 to 5) containing inorganic fibers such as glass fibers that are less stretched by moisture, mica (mica) having an average particle size of 8 μm to 150 μm. A blended backing paper (Patent Document 6) is disclosed.
また、主要な壁紙であるビニル壁紙は、塩化ビニルペーストを裏打ち紙の表面に塗工し、塗工物がゲル化し乾燥した後、印刷、発泡、エンボス等の加工を行って製品化される。ビニル壁紙は織物壁紙に比較して安価であるため広く用いられているが、塩化ビニルペーストの塗工時、あるいはその後の乾燥工程において、裏打ち紙の表面に、繊維の毛羽立ちが発生するという問題がある。特に近年においては、塩化ビニルペーストを用いる加工工程の高速化により、裏打ち紙に対してより大きなせん断力が加わり、繊維を起こす力が大きくなるために、従来より毛羽立ちが発生し易くなってきている。 Also, vinyl wallpaper, which is the main wallpaper, is made into a product by applying vinyl chloride paste on the surface of the backing paper, and the coated product is gelled and dried, and then processed by printing, foaming, embossing and the like. Vinyl wallpaper is widely used because it is cheaper than textile wallpaper, but there is a problem that fiber fluffing occurs on the surface of the backing paper during the coating of vinyl chloride paste or in the subsequent drying process. is there. In particular, in recent years, with the speeding up of the processing process using vinyl chloride paste, a greater shearing force is applied to the backing paper, and the force to raise the fibers is increased, which makes fuzzing more likely than before. .
そこで、加工工程において発生する表面の毛羽立ちが少なく、また、壁面から壁紙を剥離する際のピール適性が良い上、オープンタイムが長く、施工時の作業性に優れる壁紙用裏打ち紙として、アクリル系樹脂を含有させてなる壁紙用裏打ち紙が提案されている（特許文献７）。 Therefore, acrylic resin is used as a backing paper for wallpaper that has less fuzz on the surface that occurs in the processing process, has good peelability when peeling wallpaper from the wall surface, and has a long open time and excellent workability during construction. There has been proposed a backing paper for wallpaper made to contain (Patent Document 7).
しかしながら、特許文献１〜５に記載されたガラス繊維等の無機繊維は自己接着性が無いため、繊維がシートから脱落しやすく作業性が劣る上、抄造時、壁紙加工時、及び壁紙施工時に、繊維の毛羽立ちが生じる。また、ガラス繊維が剛直であることから、皮膚に接触するとチクチクするような刺激が生じ、人に不快感を与えたりするので、無機繊維を配合した裏打ち紙はあまり普及していない。また、特許文献６に記載されたマイカを配合した裏打ち紙の寸法安定性は十分でなく、さらにマイカの分散性が良くないため操業が困難である。また、特許文献７に記際された壁紙用裏打ち紙では、高価なアクリル系樹脂を（望ましくは２ｇ／ｍ２〜７ｇ／ｍ２）含有させるため、生産コストが高くなり実用的でない。
従って本発明の目的は、塩化ビニルペースト等の塗工時、あるいはその後の乾燥工程において毛羽立ちの発生が少なく、壁紙施工後に目開きが生じない壁紙用裏打ち紙を提供することにある。
However, since inorganic fibers such as glass fibers described in Patent Documents 1 to 5 do not have self-adhesiveness, the fibers are easily dropped from the sheet and workability is inferior, and at the time of papermaking, wallpaper processing, and wallpaper construction, Fiber fluffing occurs. In addition, since the glass fiber is rigid, when it comes into contact with the skin, a tingling irritation occurs, which causes discomfort to humans. Therefore, backing paper containing inorganic fibers has not been widely used. Moreover, the dimensional stability of the backing paper containing the mica described in Patent Document 6 is not sufficient, and furthermore, the operation of the mica is difficult because the mica dispersibility is not good. Further, the backing paper for wallpaper described in Patent Document 7 contains an expensive acrylic resin (preferably 2 g / m 2 to 7 g / m 2 ), which increases production costs and is not practical.
Accordingly, an object of the present invention is to provide a backing paper for wallpaper which is less likely to generate fuzz during the coating of vinyl chloride paste or the like, or in the subsequent drying process, and does not cause opening after the wallpaper is applied.
本発明者らは上記目的について鋭意検討した結果、抄紙機で製造される壁紙用裏打ち紙に、特定の範囲の繊維長と繊度を有し、熱可塑性樹脂を含む合成繊維を含有させ、さらに裏打ち紙中の合成繊維の含有率を特定した場合には、壁紙の寸法安定性と毛羽立ちが良好となるとことを見出し、本発明を達成するに至った。
即ち本発明は、パルプ繊維を含む壁紙用裏打ち紙であって、前記壁紙用裏打ち紙は、熱可塑性樹脂を含む合成繊維を５〜２５質量％含有し、前記合成繊維の繊維長は１ｍｍ以上４ｍｍ以下、繊度が０．１ｄｔｅｘ以上４．０ｄｔｅｘ以下であることを特徴とする壁紙用裏打ち紙である。
また、前記壁紙用裏打ち紙中に、さらに填料を１質量％以上３０質量％以下の範囲で含有することが好ましく、前記填料は焼成クレーを含有することが好ましい。
As a result of intensive studies on the above object, the inventors of the present invention have incorporated a synthetic fiber containing a thermoplastic resin having a fiber length and fineness within a specific range into a wallpaper backing paper produced by a paper machine. When the content of the synthetic fiber in the paper is specified, it has been found that the dimensional stability and fuzziness of the wallpaper are improved, and the present invention has been achieved.
That is, the present invention is a wallpaper backing paper containing pulp fibers, wherein the wallpaper backing paper contains 5 to 25% by mass of a synthetic fiber containing a thermoplastic resin, and the fiber length of the synthetic fiber is 1 mm or more and 4 mm. Hereinafter, the backing paper for wallpaper is characterized in that the fineness is 0.1 dtex or more and 4.0 dtex or less.
Further, the backing paper for wallpaper preferably further contains a filler in the range of 1% by mass to 30% by mass, and the filler preferably contains baked clay.
本発明の壁紙用裏打紙は、塩化ビニルペースト等の塗工時、あるいはその後の乾燥工程において、裏打ち紙の表面繊維が起き上がらず、毛羽立ちの発生が少なくなるだけでなく、貼付後に目開きが生じないので見栄えを良くすることができる。 The backing paper for wallpaper according to the present invention does not cause surface fibers of the backing paper to rise during the coating of vinyl chloride paste or the subsequent drying process, resulting in less fuzzing and opening after application. Because it is not, it can improve the appearance.
以下、本発明の実施形態について説明する。
本発明の壁紙用裏打ち紙はその表面に化粧層を設けて壁紙とする。例えば、化粧層して塩化ビニル樹脂層、オレフィン樹脂層、織物層、紙層、無機質層を設け、壁紙とすることができる。いずれの場合にも、化粧層には必要に応じて表面印刷、発泡処理、エンボス処理を行うことができる。
Hereinafter, embodiments of the present invention will be described.
The backing paper for wallpaper of the present invention has a decorative layer on its surface to provide wallpaper. For example, a vinyl chloride resin layer, an olefin resin layer, a fabric layer, a paper layer, and an inorganic layer can be provided as a decorative layer to make a wallpaper. In any case, the decorative layer can be subjected to surface printing, foaming treatment and embossing treatment as necessary.
本発明で使用する熱可塑性合成繊維の形態としては、繊維の繊維長が１〜４ｍｍであることが好ましい。１ｍｍ未満であると抄紙性は良好であるが、裏打ち紙の寸法安定性が低下する。繊維の繊維長が４ｍｍを超えると、毛羽立ちの発生量が多くなる上、繊維の離解や分散等の調製工程時に、配管、パルプ貯蔵槽、抄紙機ストックインレット、脱水ワイヤー等において、合成繊維同士あるいは合成繊維と木材パルプ繊維が絡まり合ってフロックを形成し易くなり、地合の悪化や断紙が起こり易くなる。より好ましくは３ｍｍ未満である。 As a form of the thermoplastic synthetic fiber used by this invention, it is preferable that the fiber length of a fiber is 1-4 mm. If it is less than 1 mm, the paper-making property is good, but the dimensional stability of the backing paper decreases. When the fiber length exceeds 4 mm, the amount of fluffing increases, and during the preparation process such as disaggregation and dispersion of the fiber, in the piping, pulp storage tank, paper machine stock inlet, dewatering wire, etc. Synthetic fibers and wood pulp fibers are entangled with each other, so that flocs are easily formed. More preferably, it is less than 3 mm.
本発明で使用する熱可塑性合成繊維の繊度（太さ）は０．１〜４．０ｄｔｅｘであることが好ましい。繊維の繊度が０．１ｄｔｅｘ未満であると裏打ち紙の紙力が低下し、断紙が起こり易くなる。繊維の繊度が４．０ｄｔｅｘを超えると、毛羽立ちの発生量が多くなる。好ましくは３．３ｄｔｅｘ以下であり、より好ましくは、２．０ｄｔｅｘ以下である。 The fineness (thickness) of the thermoplastic synthetic fiber used in the present invention is preferably 0.1 to 4.0 dtex. If the fineness of the fiber is less than 0.1 dtex, the paper strength of the backing paper is reduced, and paper breakage tends to occur. When the fineness of the fiber exceeds 4.0 dtex, the amount of fluffing increases. Preferably it is 3.3 dtex or less, More preferably, it is 2.0 dtex or less.
本発明の壁紙用裏打ち紙は、上述した合成繊維を５質量％以上２５質量％以下の範囲で含有する。このように、水分による伸縮の起こり難い合成繊維を使用することにより、吸水による壁紙のカール及び乾燥後の目開きの発生を防止することができる。合成繊維が５質量％未満であると寸法安定性が十分でなく、目開きが発生し易くなる。また、熱可塑性合成繊維の含有率が２５質量％を超えると塩化ビニルペースト等の塗工時に毛羽立ちの発生量が多くなる。より好ましくは１５質量％以下である。 The backing paper for wallpaper of the present invention contains the above-described synthetic fiber in a range of 5% by mass to 25% by mass. In this way, by using synthetic fibers that do not easily expand and contract due to moisture, it is possible to prevent the wallpaper from curling due to water absorption and the opening after drying. If the synthetic fiber is less than 5% by mass, the dimensional stability is not sufficient, and openings are likely to occur. On the other hand, when the content of the thermoplastic synthetic fiber exceeds 25% by mass, the amount of fluffing increases when a vinyl chloride paste or the like is applied. More preferably, it is 15 mass% or less.
