An adhesive layer is laminated, and the adhesive layer contains a thermal adhesive resin having an MFR (melt flow rate) of 100 to 220 or a thermal adhesive resin having a viscosity of 1000 to 11000 Pa · s, Regarding the sheet.
The invention according to claim 2 is composed of at least one of a sheet-like base material having irregularities, pulp contained in the base material, and hydrophobic shrinkable fibers , and is bonded to one surface of the sheet-like base material The adhesive layer is laminated, and the adhesive layer is laminated so as to be in contact with the first adhesive layer and the first adhesive layer laminated so as to be in contact with one surface of the sheet-like substrate. The first adhesive layer includes a heat-adhesive resin having a viscosity of 5000 to 11000 Pa · s, and the second adhesive layer has a viscosity of 1000 to 5000 Pa · s. The present invention relates to a heat-adhesive sheet comprising the heat-adhesive resin of s.
The invention according to claim 3, irregularities of the sheet-like base material, relates to a heat-adhesive sheet according to claim 1 or 2, characterized in that it is formed by the creping or embossing.
請求項１に係る熱接着性シートは、ＭＦＲ（メルトフローレート）が１００〜２２０の熱接着性樹脂又は粘度が１０００〜１１０００Ｐａ・ｓの熱接着性樹脂を含むことにより、ノンスチームアイロンやコードレスアイロン等の熱容量の小さい熱源を使用した場合であっても、簡単に接着剤層を溶融させることができ、襖、障子或いは壁などの被貼着体表面に手軽に貼着することができる。しかも、この熱接着性シートは、被貼着体表面との接着力が強く、アイロン等を使用して接着剤を溶融させて被貼着体表面に貼着する際に強い押圧力を加える必要がない。従って、請求項１に係る熱接着性シートは、ノンスチームアイロンを使用することができるので、壁面や天井面に直接貼着することができる。また表面に凹凸が形成された被貼着体に貼着する場合でも、接着剤層が容易に溶融するので、溶融した接着剤が凹凸にすばやく入り込み、強固に貼着することができる。
また、基材が凹凸を有することにより、被貼着体の表面に貼着する際に、基材が熱収縮した場合であっても、凹凸が熱収縮を吸収することができ、熱が加えられていない部分に熱収縮が広範囲に及ぶことを防いで、シワやフクラミが生じることを防止することができる。
さらに、基材にパルプが含有されている場合は、被貼着体の表面に貼着する際にパルプに含まれている水分が蒸発して接着剤層の溶融を補助することができ、基材に疎水性収縮繊維が含有されている場合は、被貼着体の表面に貼着した後、湿温度の変化により基材が伸縮するのを防ぐことができる。
請求項２に係る熱接着性シートは、接着剤層が高粘度の接着剤層と低粘度の接着剤層とから構成されているので、被貼着体に凹凸がある場合、低粘度の接着剤層が先に凹凸の凹みに入り込むために接着性が向上し、更に高粘度の接着剤により、より強固に固着させることができる。また、低粘度の接着剤層が主に被着体との接着に寄与し、高粘度の接着剤層によって、低粘度の接着剤層が基材に染み出すことを防いで、シワやフクラミが生じることを防止することもできる。
また、基材が凹凸を有することにより、被貼着体の表面に貼着する際に、基材が熱収縮した場合であっても、凹凸が熱収縮を吸収することができ、熱が加えられていない部分に熱収縮が広範囲に及ぶことを防いで、シワやフクラミが生じることを防止することができる。
さらに、基材にパルプが含有されている場合は、被貼着体の表面に貼着する際にパルプに含まれている水分が蒸発して接着剤層の溶融を補助することができ、基材に疎水性収縮繊維が含有されている場合は、被貼着体の表面に貼着した後、湿温度の変化により基材が伸縮するのを防ぐことができる。
請求項３に係る熱接着性シートは、被貼着体の表面に貼着する際に、基材が熱収縮した場合であっても、エンボス加工やクレープ加工の凹凸が熱収縮を吸収することができ、熱が加えられていない部分に熱収縮が広範囲に及ぶことを防いで、シワやフクラミが生じることを防止することができる。
The heat-adhesive sheet according to claim 1 includes a heat-adhesive resin having an MFR (melt flow rate) of 100 to 220 or a heat-adhesive resin having a viscosity of 1000 to 11000 Pa · s, whereby a non-steam iron or a cordless iron Even when using a heat source having a small heat capacity such as an adhesive layer, the adhesive layer can be easily melted and can be easily attached to the surface of an adherend such as a bag, a shoji or a wall. Moreover, this heat-adhesive sheet has a strong adhesive force with the surface of the adherend, and it is necessary to apply a strong pressing force when the adhesive is melted and stuck to the surface of the adherend using an iron or the like. There is no. Therefore, since the non-steam iron can be used for the heat-adhesive sheet according to the first aspect, it can be directly attached to a wall surface or a ceiling surface. Moreover, even when sticking to a to-be-adhered body in which the unevenness | corrugation was formed on the surface, since an adhesive bond layer melt | dissolves easily, the fuse | melted adhesive enters quickly into an unevenness | corrugation, and can adhere firmly.
In addition, since the substrate has unevenness, the unevenness can absorb the heat shrinkage even when the substrate is thermally contracted when the substrate is adhered to the surface of the adherend, and heat is applied. It is possible to prevent the heat shrinkage from spreading over a wide area and prevent the generation of wrinkles and scum.
Furthermore, when pulp is contained in the base material, the moisture contained in the pulp evaporates when sticking to the surface of the adherend, and the melting of the adhesive layer can be assisted. When the material contains hydrophobic shrinkable fibers, the base material can be prevented from expanding and contracting due to a change in wet temperature after being attached to the surface of the adherend.
In the heat-adhesive sheet according to claim 2 , the adhesive layer is composed of a high-viscosity adhesive layer and a low-viscosity adhesive layer. Adhesiveness is improved because the agent layer first enters the recesses and depressions, and the adhesive layer can be more firmly fixed with a high-viscosity adhesive. In addition, the low-viscosity adhesive layer mainly contributes to adhesion to the adherend, and the high-viscosity adhesive layer prevents the low-viscosity adhesive layer from oozing out to the base material, so It can also be prevented from occurring.
In addition, since the substrate has unevenness, the unevenness can absorb the heat shrinkage even when the substrate is thermally contracted when the substrate is adhered to the surface of the adherend, and heat is applied. It is possible to prevent the heat shrinkage from spreading over a wide area and prevent the generation of wrinkles and scum.
Furthermore, when pulp is contained in the base material, the moisture contained in the pulp evaporates when sticking to the surface of the adherend, and the melting of the adhesive layer can be assisted. When the material contains hydrophobic shrinkable fibers, the base material can be prevented from expanding and contracting due to a change in wet temperature after being attached to the surface of the adherend.
The heat-adhesive sheet according to claim 3 has an unevenness of embossing and creping to absorb heat shrinkage even when the base material is heat-shrinked when sticking to the surface of the adherend. It is possible to prevent the thermal contraction over a wide range in a portion where heat is not applied, and to prevent the generation of wrinkles and flaming.
