54−27182号公報、特開昭54−55086号公報、特開
昭55−17560号公報等）。しかしながらクツシヨン
性や軽量性の面でまだ不充分であつた。(Prior art) Thermoplastic resin foams are flexible and have excellent heat insulating and sound absorbing properties, so they can be used as cushioning materials, heat insulating materials,
Widely used as sound absorbing materials. It is also widely practiced to laminate foam sheets with nonwoven fabrics, cloth, and plastic films (for example,
54-27182, JP 54-55086, JP 55-17560, etc.). However, it was still unsatisfactory in terms of cushioning properties and light weight.
（本考案が解決しようとする問題点）
本考案の目的は、柔軟で断熱性、吸音性等にす
ぐれ、かつクツシヨン性のすぐれた軽量な積層シ
ートを提供することにある。(Problems to be Solved by the Present Invention) An object of the present invention is to provide a lightweight laminated sheet that is flexible, has excellent heat insulation properties, sound absorption properties, etc., and has excellent cushioning properties.
（問題点を解決するための手段）
本考案は立体網状シートの両面に発泡シートが
積層されてなる積層シートである。(Means for Solving the Problems) The present invention is a laminated sheet in which foam sheets are laminated on both sides of a three-dimensional reticulated sheet.
上記立体網状シートは直径0.2〜2.0mmの多数の
連続する熱可塑性樹脂フイラメントが立体的に屈
曲しかつ所々交叉して延び、交叉位置で相互に融
着して多数の山部と山部間のくぼみ部が形成され
たシートである。 The above-mentioned three-dimensional reticular sheet has a large number of continuous thermoplastic resin filaments with a diameter of 0.2 to 2.0 mm that are bent three-dimensionally and extend to intersect in some places, and are fused to each other at the intersecting positions to form a large number of ridges between the ridges. This is a sheet with depressions formed therein.
フイラメントを構成する樹脂は熱可塑性であれ
ば任意の樹脂が使用可能であるが、クツシヨン
性、柔軟性等がすぐれたものが好ましく、たとえ
ばポリエチレン、ポリプロピレン、ナイロン、ポ
リエチレンテレフタレート、ポリ塩化ビニル、ポ
リカーボネート等があげられる。又、フイラメン
トに耐候性、耐熱性等を付与したり着色するため
に、従来公知の紫外線安定剤、熱安定剤、着色剤
等が含まれていてもよい。 Any thermoplastic resin can be used as the resin constituting the filament, but those with excellent cushioning properties, flexibility, etc. are preferable, such as polyethylene, polypropylene, nylon, polyethylene terephthalate, polyvinyl chloride, polycarbonate, etc. can be given. Further, in order to impart weather resistance, heat resistance, etc. to the filament, or to color it, conventionally known ultraviolet stabilizers, heat stabilizers, colorants, etc. may be included.
フイラメントの太さは細いと機械的強度が小さ
くなりクツシヨン性がなくなり、逆に太くなると
空隙率が低下し、嵩比重が大きくなりかつ柔軟性
が低下するので、フイラメントの直径は0.2〜2.0
mmに限定されるのである。 If the filament is thin, its mechanical strength will be low and the cushioning properties will be lost; if it is thick, the porosity will decrease, the bulk specific gravity will increase, and the flexibility will decrease, so the diameter of the filament should be 0.2 to 2.0.
It is limited to mm.
又、立体網状シートは柔軟であつてクツシヨン
性がすぐれ軽量であることが必要なので厚さに対
する面積重量は50000g／m3以下であつて空隙率
は95％より大である。 Furthermore, since the three-dimensional reticular sheet needs to be flexible, have excellent cushioning properties, and be lightweight, the area weight relative to the thickness is 50,000 g/m 3 or less, and the porosity is greater than 95%.
立体網状シートの製造は任意の方法が採用され
てよく、たとえば特公昭58−9186号公報に記載の
方法が好適に採用される。 Any method may be used to produce the three-dimensional reticulated sheet, and for example, the method described in Japanese Patent Publication No. 58-9186 is preferably employed.
上記発泡シートとしてはたとえばポリエチレ

があげられるが、断熱性、クツシヨン性等から独
立気泡のポリオレフイン発泡シートが好ましく、
その発泡倍率は５〜40倍が好ましい。 Examples of the foamed sheet include foamed sheets made of polyolefin such as polyethylene and polypropylene, polyurethane, nylon, polyester, etc., but closed-cell polyolefin foamed sheets are preferred from the viewpoint of heat insulation properties, cushioning properties, etc.
The expansion ratio is preferably 5 to 40 times.
立体網状シートと発泡シートの積層方法は任意
の方法が採用されてよく、たとえば接着剤で接着
する方法、熱融着する方法等があげられる。 Any method may be used to laminate the three-dimensional reticulated sheet and the foamed sheet, such as bonding with an adhesive, heat-sealing, and the like.
