Description
本発明は、家具や車両などの表皮材に使用される、合成樹脂シートと繊維構造シートとの積層体である皮革様構造物及びその製造方法に関する。 The present invention relates to a leather-like structure, which is a laminate of a synthetic resin sheet and a fiber structure sheet, and a method for producing the same, which are used for skin materials such as furniture and vehicles.
従来、家具や車両などの表皮材として皮革様構造物が用いられている。皮革様構造物の良く知られている例としては、塩化ビニル樹脂シートと可撓性基材シートとの積層体がある。 Conventionally, leather-like structures have been used as skin materials for furniture and vehicles. A well-known example of a leather-like structure is a laminate of a vinyl chloride resin sheet and a flexible base sheet.
このような積層体の長所としては、（１）安価である、（２）汚れにくい、（３）燃えにくい、（４）摩耗しにくい、等がある。しかしながら、（５）燃やした際に有害ガスが発生する、（６）意匠の自由度に欠ける、等の問題点が指摘されている。 Advantages of such a laminate include (1) being inexpensive, (2) not easily contaminated, (3) difficult to burn, and (4) difficult to wear. However, problems such as (5) generation of harmful gas when burned and (6) lack of design freedom are pointed out.
これらの問題点を解決する新たな皮革様積層体が模索されており、例えば特許文献１には、共重合ポリエステルからなる柔軟性フイルムと可撓性基材シートとが積層され、その柔軟性フイルムの表面に凹凸パターンが形成された皮革様積層体が開示されている。 A new leather-like laminate that solves these problems has been sought. For example, in Patent Document 1, a flexible film made of a copolyester and a flexible base sheet are laminated, and the flexible film is obtained. A leather-like laminate having a concavo-convex pattern formed on its surface is disclosed.
また、特許文献２にはＪＩＳ−Ａ硬度が７０〜９８のポリエステルエラストマーからなる無孔質層と繊維質基体層とが積層され、その無孔質層の表面に凹凸模様または鏡面模様が形成された積層体が開示されている。
しかし、上記のような従来技術においては、フイルムについては一定の成果が得られているが、基材とフイルムの接着性や基材そのものに問題があり、摩耗強度が低かったり、基布が破断されやすかったり、積層体を家具や車両の骨格に貼り付ける際に「たるみ」や「わらい」（伸張後の残留歪み）が生じたりするという問題があり、必ずしも満足のいく製品は得られていなかった。そのため、これらの問題点の改善が望まれている。 However, in the prior art as described above, certain results have been obtained for the film, but there are problems with the adhesion between the substrate and the film and the substrate itself, the wear strength is low, and the base fabric is broken. And there is a problem that "sagging" and "soft" (residual strain after stretching) occur when the laminate is pasted on the frame of furniture or vehicles, and satisfactory products are not always obtained. It was. Therefore, improvement of these problems is desired.
本発明は上記に鑑みてなされたものであり、フィルムと基材の接着が強固で耐摩耗性に優れ、基布の破断強度に優れ、かつ表皮材として貼り込み作業がしやすい皮革様構造物を提供することを目的とする。 The present invention has been made in view of the above, and is a leather-like structure in which adhesion between a film and a substrate is strong, excellent in abrasion resistance, excellent in breaking strength of a base fabric, and easy to be pasted as a skin material.

その場合、繊維構造シートがポリエステル合成樹脂シートの厚みの２０〜８０％に食い込むように積層されていることが好ましい（請求項５）。 In that case, it is preferable that the fiber structure sheet is laminated so as to bite into 20 to 80% of the thickness of the polyester synthetic resin sheet.
請求項６の製造方法は、ポリエステル合成樹脂シートと繊維構造シートとを積層させてなる皮革様構造物の製造方法であって、ホットメルトタイプのポリエステル合成樹脂シートと厚みが０．３〜２．０ｍｍであり、定荷重伸度が１〜１５０％であり、かつＫＥＳ圧縮仕事量が０．０１５ｇｆ・ｃｍ／ｃｍ２以上である繊維構造シートとを、上記ポリエステル合成樹脂シートの融点よりも１０℃以上高い温度で、１〜１０ｋｇ／ｃｍ２に加圧して貼り合わせることを特徴とする。 The manufacturing method of Claim 6 is a manufacturing method of the leather-like structure formed by laminating | stacking a polyester synthetic resin sheet | seat and a fiber structure sheet | seat, Comprising: Thickness is 0.3-2. A fiber structure sheet having a constant load elongation of 1 to 150% and a KES compression work of 0.015 gf · cm / cm 2 or more is 10 ° C. above the melting point of the polyester synthetic resin sheet. It is characterized by being bonded by pressing at 1-10 kg / cm 2 at a higher temperature.
請求項１の皮革様構造物は、フィルムと基材の接着が強固なため耐摩耗性に優れ、基布の破断強度に優れ、かつ表皮材として貼り込み作業がしやすいものとなる。 The leather-like structure according to claim 1 is excellent in abrasion resistance because of the strong adhesion between the film and the base material, excellent in the breaking strength of the base fabric, and easy to apply as a skin material.

請求項６の製造方法によれば、上記した性能を有する本発明の皮革様構造物が容易に得られる。 According to the manufacturing method of the sixth aspect, the leather-like structure of the present invention having the above-described performance can be easily obtained.
本発明の皮革様構造物は、特定の性状を有する繊維構造シートとポリエステル合成樹脂シートとを貼り合わせることにより得られる。 The leather-like structure of the present invention is obtained by laminating a fiber structure sheet having specific properties and a polyester synthetic resin sheet.
皮革様構造物に求められる性能として、破れにくいことや、表皮材としたときに貼り込み作業が楽であることは重要な要件である。 As performance required for a leather-like structure, it is an important requirement that it is not easily torn and that the pasting work is easy when it is used as a skin material.
そのため、本発明で用いる繊維構造シートは、厚みが０．３〜２．０ｍｍの範囲内であるものとする。厚みが０．３ｍｍ未満であると、十分な強度が得られず、破れ易くなる。また、厚みが２．０ｍｍより大きくなると、強度は十分であるが、これ以上厚くしても効果は変わらず、一方でコスト高になるという問題が生じる。 Therefore, the fiber structure sheet used in the present invention has a thickness in the range of 0.3 to 2.0 mm. When the thickness is less than 0.3 mm, sufficient strength cannot be obtained and the film is easily broken. Further, when the thickness is larger than 2.0 mm, the strength is sufficient, but even if it is thicker than this, the effect is not changed, but there is a problem that the cost is increased.
次に、本発明で用いる繊維構造シートは、ＪＩＳ Ｌ１０９６Ｂ法によって測定された定荷重伸度が縦横共に１〜１５０％の範囲内であるものとし、好ましくは５〜８０％、更に好ましくは１０〜４０％の範囲内であるものとする。 Next, the fiber structure sheet used in the present invention has a constant load elongation measured by the JIS L1096B method in the range of 1 to 150% in both length and width, preferably 5 to 80%, more preferably 10 to 10. It shall be in the range of 40%.
定荷重伸度を上記範囲内にコントロールすることによって積層体の伸張後の残留歪みを抑えることができ、歪みが少ないことによって耐摩耗性も向上させることができる。定荷重伸度が１％未満であると、積層体が伸びないために貼り込み性が低下するという問題がある。また、定荷重伸度が１５０％を超えると、伸張後の残留歪みを抑えることができず、耐摩耗性も低くなるという問題がある。 By controlling the constant load elongation within the above range, residual strain after stretching of the laminate can be suppressed, and wear resistance can be improved by reducing the strain. If the constant load elongation is less than 1%, there is a problem that the laminate is not stretched and the sticking property is lowered. Further, when the constant load elongation exceeds 150%, there is a problem that residual strain after stretching cannot be suppressed and wear resistance is also lowered.
さらに、本発明で用いる繊維構造シートは、ＫＥＳ圧縮仕事量が０．０１５ｇｆ・ｃｍ／ｃｍ２以上であるものとし、好ましくは０．０２ｇｆ・ｃｍ／ｃｍ２以上であり、さらに好ましくは０．０４ｇｆ・ｃｍ／ｃｍ２以上であるものとする。ＫＥＳ圧縮仕事量はＫＥＳシステム（Ｋａｗａｂａｔａ Ｅｖａｌｕａｔｉｏｎ Ｓｙｓｔｅｍ）の風合い測定法に準じて測定される。ＫＥＳ圧縮仕事量は衝撃を吸収する能力を示し、この数値が０．０１５ｇｆ・ｃｍ／ｃｍ２未満であると、クッション性が低くなり、破れやすく、耐久性が低下するという問題が生じる。 Furthermore, the fiber structure sheet used in the present invention has a KES compression work of 0.015 gf · cm / cm 2 or more, preferably 0.02 gf · cm / cm 2 or more, more preferably 0.04 gf. -It shall be cm / cm 2 or more. The KES compression work is measured according to the texture measurement method of the KES system (Kawabata Evaluation System). The KES compression work indicates the ability to absorb an impact, and when this value is less than 0.015 gf · cm / cm 2 , the cushioning property is lowered, and the problem is that it is easily broken and the durability is lowered.
上記繊維構造シートの組織としては、織物、編物、不織布等を特に限定なく用いることができるが、定荷重伸度やＫＥＳ圧縮仕事量の数値範囲を考慮すると編物が好ましい。 As the structure of the fiber structure sheet, a woven fabric, a knitted fabric, a non-woven fabric, or the like can be used without any particular limitation.
また、繊維構造シートの素材としては、耐久性や強度に優れた合成繊維シートが好ましく、耐光性やリサイクル性の点からポリエステル繊維シートが特に好ましい。中でも、環境負担を低減できる点からは、再生ポリエステル糸を使用して構成されたものがより好ましい。 Moreover, as a raw material of a fiber structure sheet, a synthetic fiber sheet excellent in durability and strength is preferable, and a polyester fiber sheet is particularly preferable in terms of light resistance and recyclability. Among these, from the viewpoint that the environmental burden can be reduced, those constructed using recycled polyester yarn are more preferable.
なお、繊維構造シートはポリエステル合成樹脂シートの貼り合わせに先立って、必要に応じて公知の方法で染色或いは捺染することができる。 In addition, the fiber structure sheet can be dyed or printed by a known method as necessary prior to the bonding of the polyester synthetic resin sheet.
次に、本発明で用いるポリエステル合成樹脂シートは、結晶化度が１０〜７０％の範囲内であることが摩耗強度の確保と白化防止のために好ましい。 Next, the polyester synthetic resin sheet used in the present invention preferably has a crystallinity of 10 to 70% in order to ensure wear strength and prevent whitening.
また、ポリエステル合成樹脂シートのガラス転移点は３０℃以下であることが、同じく摩耗強度の確保と白化防止のために好ましい。 In addition, the glass transition point of the polyester synthetic resin sheet is preferably 30 ° C. or less, in order to ensure wear strength and prevent whitening.
ポリエステル合成樹脂シートの厚みは、２０〜１５０μｍが好ましい。２０μｍより薄いと、耐摩耗性が低下し、１５０μｍより厚くなると、風合いが硬くなり、好ましくない。 The thickness of the polyester synthetic resin sheet is preferably 20 to 150 μm. If it is thinner than 20 μm, the wear resistance is lowered, and if it is thicker than 150 μm, the texture becomes hard.
ポリエステル合成樹脂シートは、公知のアクリル系、エポキシ系、ウレタン系接着剤などで上記繊維構造シートに貼り合わせても良いし、ホットメルトタイプのポリエステル合成樹脂シートを用いて、熱圧着により貼り合わせてもよい。中でもホットメルトタイプは接着剤を使用することなく良好な接着性が得られる点で好ましい。 The polyester synthetic resin sheet may be bonded to the fiber structure sheet with a known acrylic, epoxy, or urethane adhesive, or bonded by thermocompression using a hot melt type polyester synthetic resin sheet. Also good. Among these, the hot melt type is preferable in that good adhesiveness can be obtained without using an adhesive.
ホットメルトタイプのポリエステル合成樹脂シートとしては、東洋紡績（株）製の「バイロン（登録商標）（結晶性ポリエステル）」シリーズ、オージーフィルム（株）製の「フレクロン」シリーズ、日本マタイ（株）製の「エルファンＰＨ」シリーズ、シーダム（株）製の「マテリ」シリーズなどが挙げられる。融点としては、１００℃〜１９０℃の範囲内であることが、耐熱性、加工性の面から好ましい。融点が１００℃よりも低いと製品の耐熱性が悪くなるため好ましくなく、１９０℃よりも高いと、貼り合わせの際に基布が熱により変形（圧縮）したり、堅牢度が悪くなるため好ましくない。 Hot melt type polyester synthetic resin sheets include "Byron (registered trademark) (crystalline polyester)" series manufactured by Toyobo Co., Ltd., "Flexlon" series manufactured by Aussie Film Co., Ltd., manufactured by Nippon Matai Co., Ltd. "Erphan PH" series, "Materi" series made by Seadom Co., Ltd. The melting point is preferably in the range of 100 ° C. to 190 ° C. from the viewpoint of heat resistance and workability. When the melting point is lower than 100 ° C., the heat resistance of the product is deteriorated, which is not preferable. Absent.
ホットメルト合成樹脂シートの熱圧着条件としては、温度が〔ホットメルト合成樹脂シートの融点＋１０℃〕以上、圧力が１〜１０ｋｇ／ｃｍ２、時間が３０〜１２０秒であることが好ましい。〔ホットメルト合成樹脂シートの融点＋１０℃〕未満の温度では、ホットメルト合成樹脂シートが軟化せず、基材との接着力が低下する。しかし、〔ホットメルト合成樹脂シートの融点＋１０℃〕以上とは言え、繊維構造シートが収縮などの変形を起こさない程度の温度以下でポリエステル合成樹脂シートの貼り付け加工を行う必要がある。例えば繊維構造シートがポリエステル繊維シートの場合は、２００℃程度が上限になる。 As conditions for thermocompression bonding of the hot-melt synthetic resin sheet, the temperature is preferably [the melting point of the hot-melt synthetic resin sheet + 10 ° C.] or more, the pressure is 1 to 10 kg / cm 2 , and the time is preferably 30 to 120 seconds. At a temperature lower than [melting point of hot melt synthetic resin sheet + 10 ° C.], the hot melt synthetic resin sheet is not softened, and the adhesive force with the substrate is lowered. However, although it is above [melting point of hot-melt synthetic resin sheet + 10 ° C.] or higher, it is necessary to perform the process of attaching the polyester synthetic resin sheet at a temperature that does not cause deformation such as shrinkage of the fiber structure sheet. For example, when the fiber structure sheet is a polyester fiber sheet, the upper limit is about 200 ° C.
上記において、接着性を高めるため、繊維構造シートをホットメルトタイプのポリエステル合成樹脂シートに食い込ませて積層させるのが好ましい。繊維構造シートの食い込み量はポリエステル合成樹脂シートの厚みの２０〜９０％であるのが好ましい。 In the above, in order to improve adhesiveness, it is preferable that the fiber structure sheet is bitten into a hot-melt type polyester synthetic resin sheet and laminated. The biting amount of the fiber structure sheet is preferably 20 to 90% of the thickness of the polyester synthetic resin sheet.
なお、ポリエステル合成樹脂シートは、繊維構造シートの貼り合わせに先立って白化を目立たなくするという目的で樹脂に顔料を加えるなどの方法で着色することができる。着色剤の付与量は樹脂に対して０．１〜２０重量％であるのが好ましい。 The polyester synthetic resin sheet can be colored by a method such as adding a pigment to the resin for the purpose of making the whitening inconspicuous prior to the bonding of the fiber structure sheets. The amount of colorant applied is preferably 0.1 to 20% by weight based on the resin.
