Description
【０００１】[0001]
本考案は熱成形用積層シートに関し、詳しくは成形性，保型性，意匠性等に優 れており、鞄，ケース，トレー等の素材として好適な熱成形用積層シートに関す る。 The present invention relates to a thermoformed laminated sheet, and more particularly to a thermoformed laminated sheet which is excellent in moldability, shape retention, and designability and is suitable as a material for bags, cases, trays, and the like.
【０００２】[0002]
従来、発泡シートを芯材として用い、表皮材として合成皮革を用い、かつ、内 装材として織布を用いた積層シートを、熱成形してなる鞄，袋物が知られている 。 BACKGROUND ART Conventionally, there has been known a bag or bag formed by thermoforming a laminated sheet in which a foamed sheet is used as a core material, synthetic leather is used as a skin material, and woven cloth is used as an interior material.
【０００３】 このものは加工工程、特に縫製工程を省力化することができ、しかも意匠性に 優れるという利点を有しているものの、表皮材の基布と内装材に用いる織布は、 共に熱成形性に問題があるため、特に内装材は片面のみの積層によりコーナー 部分で発泡シートとの剥離が生じて、製品が得られない、賦形性が低下する、 積層界面が剥離しやすく深絞りができない、芯材と内装材との積層加工を要 する等の欠点があった。Although this product has the advantage of being able to save labor in the processing process, especially in the sewing process, and is also excellent in designability, both the base fabric of the skin material and the woven fabric used for the interior material are Since there is a problem with moldability, the interior material peels off from the foamed sheet at the corners due to laminating on only one side, resulting in a product that cannot be obtained. However, there are drawbacks such as being incapable of being processed and requiring a lamination process of the core material and the interior material.
【０００４】 このため、熱成形性を改良するものとして、織布の伸び率を規定することが提 案されている（実公平３−３７９４４号公報）。すなわち、表皮材として合成皮 革（伸び率が縦，横方向共に１００％以上の織布を用いた基布を使用）を用い、 かつ、内装材として織布（伸び率が縦，横方向共に１００％以上の織布）を用い ることにより、熱成形性を改良する技術が提案されている。 しかしながら、上記の如き性能を有する織布及びその積層加工費は高価であり 、また、ノーテンション（無張力）に近い状態で積層しなければ、成形時に伸び 率が低下して成形性も低下してしまうという欠点がある。また、積層する際にシ ワが入りやすく、しかも均一になりにくいという欠点がある。For this reason, it has been proposed to regulate the elongation of the woven fabric in order to improve the thermoformability (Japanese Utility Model Publication No. 3-37944). That is, synthetic leather (a base cloth made of a woven fabric having an elongation rate of 100% or more in both the longitudinal and transverse directions is used) is used as the surface material, and the woven fabric (extension rate is applied in both the longitudinal and transverse directions) is used as the interior material. A technique for improving thermoformability by using 100% or more woven fabric) has been proposed. However, the woven fabric having the above-mentioned properties and the cost for laminating the same are expensive, and unless the layers are laminated in a state close to no tension (no tension), the elongation rate at the time of molding decreases and the formability also decreases. There is a drawback that it will end up. In addition, there are drawbacks that wrinkles are likely to occur during stacking and that it is difficult to make them uniform.
【０００５】 本考案は、このような従来品の欠点を解消し、クッション性を有しながらも、 熱成形性，保型性，意匠性等に優れており、しかも安価に得ることができ、鞄， ケース，トレー等の素材として好適な熱成形用積層シートを提供することを目的 とするものである。The present invention solves the above-mentioned drawbacks of conventional products, has excellent cushioning properties, thermoformability, shape retention, designability, and the like, and can be obtained at low cost. It is an object of the present invention to provide a thermoformed laminated sheet suitable as a material for bags, cases, trays and the like.
【０００６】[0006]
すなわち本考案は、表皮層と不織布層とからなる熱成形用積層シートを提供す るものである。 That is, the present invention provides a thermoforming laminated sheet comprising a skin layer and a non-woven fabric layer.
【０００７】 以下、本考案を図面により説明する。図１は、本考案の熱成形用積層シートの 一態様を示す説明図である。図中、符号１は表皮層であり、符号２は不織布層で ある。 表皮層１としては、熱可塑性樹脂フィルム又はシート、前記熱可塑性樹脂フィ ルム又はシートの積層品、さらには合成皮革，人工皮革のような擬革を用いるこ とができ、特に熱可塑性樹脂フィルム又はシート、或いは合成皮革又は人工皮革 が好ましい。 ここで熱可塑性樹脂フィルム又はシートとしては、例えばポリウレタン，ポリ 塩化ビニル（ＰＶＣ），ポリプロピレン（ＰＰ），ポリエチレン（ＰＥ），アク リロニトリル−ブタジエン−スチレン樹脂（ＡＢＳ），ポリアミド等の熱可塑性 樹脂からなるフィルム又はシートを挙げることができる。 この熱可塑性樹脂フィルム又はシートとしては、離型紙，エンボスロール等に より、表面に皮革調シボ（絞）を施した合成皮革調フィルムが、外観も良好で傷 が目立ちにくいため特に好ましい。 また、前記熱可塑性樹脂フィルム又はシートの積層品としては、前記の如き熱 可塑性樹脂フィルム又はシートに、ポリウレタン樹脂等のエラストマーフィルム を積層したものが好ましい。 さらに、合成皮革を用いる場合には、基布としては、伸び率が高い織布又は熱 成形に適した不織布が好適である。 この表皮層１の厚みは、２０〜１００μｍが好ましい。Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing one embodiment of the laminated sheet for thermoforming of the present invention. In the figure, reference numeral 1 is a skin layer, and reference numeral 2 is a non-woven fabric layer. As the skin layer 1, a thermoplastic resin film or sheet, a laminated product of the thermoplastic resin film or sheet, and artificial leather such as synthetic leather or artificial leather can be used. In particular, the thermoplastic resin film or sheet is used. A sheet, or synthetic leather or artificial leather is preferable. Here, the thermoplastic resin film or sheet is made of thermoplastic resin such as polyurethane, polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), acrylonitrile-butadiene-styrene resin (ABS), and polyamide. Mention may be made of films or sheets. As the thermoplastic resin film or sheet, a synthetic leather-like film having a leather-like grain (squeezing) on its surface by a release paper, embossing roll or the like is particularly preferable because the appearance is good and the scratches are not noticeable. Further, the laminated product of the thermoplastic resin film or sheet is preferably one in which an elastomer film such as a polyurethane resin is laminated on the thermoplastic resin film or sheet as described above. Further, when synthetic leather is used, a woven fabric having a high elongation or a nonwoven fabric suitable for thermoforming is suitable as the base fabric. The thickness of the skin layer 1 is preferably 20 to 100 μm.
【０００８】 次に、不織布層２としては、例えばポリプロピレン（ＰＰ），ポリエチレン（ ＰＥ），ポリエステル，ポリアミド等の熱可塑性樹脂からなる不織布であって、 熱成形可能なものが用いられる。特に、成形性、保型性、内装材としての意匠性 、毛羽立ち防止の観点から、強度比（ＭＤ／ＴＤ）が１〜２であり、しかも破断 強度が縦，横方向いずれも８０％以上の不織布シートを熱圧着したものが好まし い。なお、この不織布層としては、除電性，難帯電性，導電性を有するものを用 いることが好ましい。また、成形時に不織布層側の加熱温度を適宜選定すること により、成形品の保型性、クッション性を調整することができる。すなわち、高 温側では保型性が向上し、低温側ではクッション性が高まる。 また、この不織布層の厚みは内容物により異なるが、不織布層としては、通常 、目付け１００〜１０００ｇ／ｍ2 のものが用いられる。 このような不織布としては、例えば、出光石油化学株式会社製の熱成形用不織 布（商品名：ストラサーモ）を挙げることができる。Next, as the non-woven fabric layer 2, for example, a non-woven fabric made of a thermoplastic resin such as polypropylene (PP), polyethylene (PE), polyester, polyamide or the like and capable of being thermoformed is used. In particular, from the viewpoints of moldability, shape retention, designability as an interior material, and prevention of fuzz, the strength ratio (MD / TD) is 1 to 2, and the breaking strength is 80% or more in both the longitudinal and transverse directions. It is preferable that the non-woven sheet is thermocompression bonded. As the non-woven fabric layer, it is preferable to use one having static eliminability, antistatic property, and conductivity. Further, by appropriately selecting the heating temperature on the side of the non-woven fabric during molding, it is possible to adjust the shape retention and cushioning properties of the molded product. That is, the shape retention is improved on the high temperature side, and the cushioning property is improved on the low temperature side. The thickness of the non-woven fabric layer varies depending on the content, but a non-woven fabric layer having a basis weight of 100 to 1000 g / m 2 is usually used. Examples of such a non-woven fabric include a non-woven fabric for thermoforming manufactured by Idemitsu Petrochemical Co., Ltd. (trade name: Stratotherm).
【０００９】 次に、図２は本考案の熱成形用積層シートの他の態様を示す説明図であり、図 １の態様のものに、さらに熱可塑性合成樹脂発泡層３を設けたものである。 すなわち、不織布の厚み、樹脂の物性等から、保型性，クッション性等を補う ために、前記表皮層１と前記不織布層２との間に、熱可塑性合成樹脂発泡シート を積層することにより、熱可塑性合成樹脂発泡層３を設けたものである。 ここで用いられる熱可塑性合成樹脂発泡シートとしては、例えばポリエチレン （ＰＥ），ポリプロピレン（ＰＰ），ポリスチレン（ＰＳ）等の熱可塑性合成樹 脂からなる発泡シートを用いることができる。なお、発泡倍率は５〜４０倍とし 、厚みは１〜５ｍｍとすることが好ましい。Next, FIG. 2 is an explanatory view showing another embodiment of the thermoforming laminated sheet of the present invention, in which the thermoplastic synthetic resin foam layer 3 is further provided on the embodiment of FIG. .. That is, from the thickness of the non-woven fabric, the physical properties of the resin, etc., in order to supplement the shape retention, cushioning properties, etc., by laminating the thermoplastic synthetic resin foam sheet between the skin layer 1 and the non-woven fabric layer 2, The thermoplastic synthetic resin foam layer 3 is provided. As the thermoplastic synthetic resin foam sheet used here, for example, a foam sheet made of a thermoplastic synthetic resin such as polyethylene (PE), polypropylene (PP) or polystyrene (PS) can be used. The expansion ratio is preferably 5 to 40 times, and the thickness is preferably 1 to 5 mm.
【００１０】 以上の如き本発明の熱成形用積層シートは、著しく熱成形性が改良されており 、真空成形，圧空成形，プラグアシスト成形，熱プレス成形等の熱成形により、 容易に所望の形状に成形されて、鞄，ケース，トレー等の最終製品とされる。The above-described laminated sheet for thermoforming of the present invention has remarkably improved thermoformability and can be easily formed into a desired shape by thermoforming such as vacuum forming, pressure forming, plug assist forming, and hot press forming. Is molded into a final product such as a bag, a case, or a tray.
