Moreover, as an aluminum vapor deposition film, when the thing which gave aluminum vapor deposition to the biaxially stretched film is used, it can be said that the vertical and horizontal elongation does not become unbalanced and is more preferable as a function of the encapsulating material.

本発明によれば、保冷・保温機能を付加した風呂敷や手提げ袋等の持ち運び用被包材として使い勝手のよいものを安価に製造することができる。   According to the present invention, an easy-to-use enveloping material such as a furoshiki or a handbag provided with a cold and heat retaining function can be manufactured at low cost.

次に、本発明の実施形態として、まず、不織布積層体の製造方法を、図1を参照しながら説明する。実施形態としての不織布積層体の製造方法では、まず、所定幅を有する不織布ロール1と、不織布ロール1よりも狭い幅のアルミ蒸着フィルムロール2とを用意する。そして、不織布ロール1とアルミ蒸着フィルムロール2とを互いの幅方向中心が一致する様に配置し、それぞれから素材3,4を繰り出す。こうして各ロール1,2から繰り出された素材3,4間に、接着剤滴下装置5から、溶融した接着剤6を縞状に垂らしつつ冷却ローラー組7の間に挟み込んで接着する。そして、冷却ローラー組7から繰り出される積層体8を巻き取って積層体ロール9とする。   Next, as an embodiment of the present invention, first, a method for producing a nonwoven fabric laminate will be described with reference to FIG. In the method for manufacturing a nonwoven fabric laminate as an embodiment, first, a nonwoven fabric roll 1 having a predetermined width and an aluminum vapor deposition film roll 2 having a narrower width than the nonwoven fabric roll 1 are prepared. And the nonwoven fabric roll 1 and the aluminum vapor deposition film roll 2 are arrange | positioned so that a mutual width direction center may correspond, and the raw materials 3 and 4 are paid out from each. In this manner, the molten adhesive 6 is sandwiched between the cooling roller sets 7 while being dropped from the adhesive dropping device 5 between the raw materials 3 and 4 fed from the rolls 1 and 2 and bonded. And the laminated body 8 drawn | fed out from the cooling roller group 7 is wound up, and it is set as the laminated body roll 9. FIG.

こうして製造された不織布積層体8は、図2に示す様に、両端から所定幅Bに渡って不織布シート3のみとなり、中央にアルミ蒸着フィルム4が接着されたものとなる。また、この不織布積層体8においては、長手方向に縞状に接着線10が形成され、不織布シート3とアルミ蒸着フィルム4の重なっている範囲の全部は接着されてはいない。よって、接着線10同士の間には、通気性のある不織布シート3を介して侵入する空気を受け入れることができる。   As shown in FIG. 2, the nonwoven fabric laminate 8 manufactured in this way is only the nonwoven fabric sheet 3 over a predetermined width B from both ends, and the aluminum vapor deposition film 4 is bonded to the center. Moreover, in this nonwoven fabric laminated body 8, the adhesive line 10 is formed in stripes in the longitudinal direction, and the whole range where the nonwoven fabric sheet 3 and the aluminum vapor deposition film 4 overlap is not adhered. Therefore, the air which penetrate | invades through the breathable nonwoven fabric sheet 3 can be received between the bonding wires 10.

また、この不織布積層体8から、図3に示す様に、積層体の両端を一対の角とする様に正方形に打ち抜けば、断熱性風呂敷20を製造することができる。同様に、図4に示す様に、不織布積層体8を所定長さのカットシート31に切断し(A)、このカットシート31をアルミ蒸着フィルム4の幅中心で二つ折りにして両端をヒートシールで接合し(B)、不織布のみの部分に持ち手穴32を打ち抜けば(C)、断熱性手提げ袋30を製造することができる(D)。   In addition, as shown in FIG. 3, the nonwoven fabric laminate 8 can be manufactured by punching into a square shape so that both ends of the laminate have a pair of corners. Similarly, as shown in FIG. 4, the nonwoven fabric laminate 8 is cut into a cut sheet 31 having a predetermined length (A), the cut sheet 31 is folded in half at the center of the width of the aluminum vapor-deposited film 4, and both ends are heat sealed. (B) and punch through the handle hole 32 only in the non-woven fabric (C), the heat-insulating handbag 30 can be manufactured (D).

次に、実施例を説明する。実施例として、片面にグラビア印刷を施したポリプロピレン不織布(スパンボンド、25g/m、幅1000mm)に対して、アルミ蒸着フィルム(30μmの2軸延伸ポリエチレンフィルムの片面にアルミ蒸着、幅500mm)を、ポリプロピレン不織布の非印刷面に対してアルミ蒸着面が重なり、かつ、アルミ蒸着フィルムがポリプロピレン不織布の幅中央に位置する様にスジ状ポリエチレンラミネート共押出法で貼り合わせて図2に例示した様な構成の不織布積層体を製造し、図3に示す様に正方形に打ち抜いて断熱性風呂敷を製造した。 Next, examples will be described. As an example, an aluminum vapor-deposited film (aluminum vapor-deposited on one side of a 30 μm biaxially stretched polyethylene film, width 500 mm) is applied to a polypropylene nonwoven fabric (spunbond, 25 g / m 2 , width 1000 mm) subjected to gravure printing on one side. As shown in FIG. 2, the aluminum vapor deposition surface overlaps the non-printing surface of the polypropylene nonwoven fabric, and the aluminum vapor deposition film is laminated by a stripe polyethylene laminate coextrusion method so as to be positioned at the center of the width of the polypropylene nonwoven fabric. A non-woven fabric laminate having the structure was manufactured and punched into a square as shown in FIG. 3 to manufacture a heat insulating furoshiki.

一方、比較例として、アルミ蒸着フィルムを積層しないポリプロピレン不織布(スパンボンド、25g/m、幅1000mm)そのものを正方形に打ち抜いた不織布風呂敷を製造した。 On the other hand, as a comparative example, a nonwoven fabric furoshiki was manufactured by punching a polypropylene nonwoven fabric (spunbond, 25 g / m 2 , width 1000 mm) itself without laminating an aluminum vapor deposition film into a square.

そして、これら実施例及び比較例の風呂敷を用いて、紙コップ(低発泡ポリスチレン製、直径95mm×深さ65mmに八分目(100cc)の氷水を入れたものを包んだ場合の水温変化を計測した。なお、実験に当たり、この氷水入りの紙コップを、180mm×260mm×130mm×のポリプロピレン製のカゴの中央に置き、各風呂敷で包んだ。また、水温は、デジタル温度計(熱電対Kタイプ;(株)佐藤計量器製作所製の商品番号「SK−110」)で計測した(比較例A、実施例B)。また、もう一つの比較例として、風呂敷で包まないままの紙コップ内の氷水の温度変化もブランクとして計測した。その結果を、表1及び図5に示す。   Then, using the furoshikis of these examples and comparative examples, a change in water temperature was measured when a paper cup (made of low foam polystyrene, diameter 95 mm × depth 65 mm with ice water of the eighth minute (100 cc) put therein was wrapped. In the experiment, the iced water-containing paper cup was placed in the center of a polypropylene basket of 180 mm × 260 mm × 130 mm × and wrapped with a furoshiki.The water temperature was measured with a digital thermometer (thermocouple K type; (Comparative Example A, Example B) measured by a product number “SK-110” manufactured by Sato Keiki Seisakusho Co., Ltd. As another comparative example, ice water in a paper cup not wrapped in a furoshiki The temperature change was also measured as a blank, and the results are shown in Table 1 and FIG.

実験結果から、ブランク及び比較例に比べて、実施例は断熱効果の差が確認できた。また、この実施例の風呂敷は、包装するに当たり、中央にカゴを置き、まず、アルミ蒸着フィルムが積層されている方の角を持ち上げて折り、その後、アルミ蒸着フィルムの積層されていない角を持ち上げて結んだところ、比較例の風呂敷と変わらない使用感であった。従って、実施例では、本発明の目的である使い勝手のよい断熱性風呂敷が製造できたといえる。また、その製造方法は、上述の実施形態の通りであり、低コストで実施できた。   From the experimental result, the Example has confirmed the difference of the heat insulation effect compared with the blank and the comparative example. In addition, the furoshiki of this embodiment, when packaging, put a basket in the center, first lift and fold the corner where the aluminum vapor deposition film is laminated, then lift the corner where the aluminum vapor deposition film is not laminated As a result, it was the same feeling as the comparative example furoshiki. Therefore, in the Examples, it can be said that an easy-to-use heat insulating furoshiki, which is the object of the present invention, was manufactured. Moreover, the manufacturing method is as the above-mentioned embodiment, and could be implemented at low cost.

以上、発明の実施形態並びに実施例を説明したが、本発明は、これに限定されるものではなく、例えば、不織布シートの幅を1200mm、アルミ蒸着フィルムの幅を700mmとしたり、持ち手穴32だけでなく不織布のみの部分のヒートシール部をも切断してレジ袋の様な形状の手提げ袋とするなど、その要旨を逸脱しない範囲内における種々の変更が可能である。   As mentioned above, although embodiment and the Example of invention were described, this invention is not limited to this, For example, the width | variety of a nonwoven fabric sheet shall be 1200 mm, the width | variety of an aluminum vapor deposition film shall be 700 mm, or the handle hole 32 In addition, various modifications can be made without departing from the gist of the invention, such as cutting a heat-sealed portion of only a non-woven fabric into a handbag having a shape like a plastic bag.
