Abstract
Description
本発明は、主として皮膚面、特に関節部位を固定するために用いる伸縮性粘着包帯に関するものであり、例えば靱帯の動きを固定して関節の動きを制限するテーピング用途などに好適な伸縮性粘着包帯を提供するものである。 The present invention relates to an elastic adhesive bandage mainly used for fixing a skin surface, particularly a joint site, and is suitable for, for example, a taping application in which the movement of a joint is limited by fixing the movement of a ligament. Is to provide.
一般的に粘着包帯は医療衛生分野やスポーツ分野などで用いられ、皮膚面に貼付して使用されるものであって、布基材の片面に粘着剤層を形成したものが用いられている。特に、粘着包帯でテーピングを行う場合、関節や筋肉、腱、靱帯などの関節部位に貼付することによって、運動する際に関節の可動範囲を超える動きを制限すると共に、可動範囲内の動きを妨げないので、障害を起している部位の自然治癒を早め、さらにはケガなどの事前予防も行えるものであり、粘着包帯は一般的に汎用されているものである。 In general, the adhesive bandage is used in the medical hygiene field, the sports field, and the like, and is used by being attached to the skin surface, in which an adhesive layer is formed on one side of a cloth base material. In particular, when taping with an adhesive bandage, sticking to joints such as joints, muscles, tendons, and ligaments restricts movement beyond the movable range of the joint when exercising and prevents movement within the movable range. Since there is no such thing, the natural healing of the site where the disorder has occurred can be accelerated, and further pre-prevention such as injury can be performed, and the adhesive bandage is generally used.
このような粘着包帯としては、貼付部位の動きを制限する目的では非伸縮性基材を用いた粘着包帯が用いられる。一方、屈曲部や湾曲部、特に関節部などの皮膚面が伸縮するような部位に対しては、貼付部位を固定すると共に皮膚の動きに適度に追従するために、伸縮性基材を用いた粘着包帯が用いられている。（特許文献１参照）
さらに、布基材への外部からの吸水を防止するために、布基材の片面にプラスチックフィルムを積層した基材も用いられている。例えば、ポリオレフィン樹脂を積層した布粘着テープ用の基材としては、養生や梱包、補修などの用途において、基材の片面にプライマーや接着剤を塗布、乾燥させ、この上にポリエチレン樹脂などのポリオレフィン樹脂を積層する方法や、基布面に直接ポリオレフィン樹脂を共押出して積層する方法が知られている。（特許文献２、特許文献３および特許文献４参照）
As such an adhesive bandage, an adhesive bandage using a non-stretchable base material is used for the purpose of restricting the movement of the application site. On the other hand, an elastic base material was used to fix the affixed part and appropriately follow the movement of the skin for a part where the skin surface such as a bent part or a curved part, particularly a joint part, is stretched and contracted. An adhesive bandage is used. (See Patent Document 1)
Furthermore, in order to prevent water absorption from the outside to the cloth base material, a base material in which a plastic film is laminated on one side of the cloth base material is also used. For example, as a base material for a cloth adhesive tape laminated with a polyolefin resin, a primer or an adhesive is applied to one side of the base material and dried on a surface of the base material for purposes such as curing, packing, and repairing, and then a polyolefin such as a polyethylene resin. A method of laminating a resin and a method of coextruding a polyolefin resin directly on the surface of a base fabric and laminating are known. (See Patent Document 2, Patent Document 3 and Patent Document 4)
上記伸縮性基材を用いた粘着包帯としては、一般的に伸縮性基布として綿１００％の糸に強く撚りをかけた強撚布が用いられており、貼付部位の固定性に優れたものである。しかしながら、このような粘着包帯は比較的厚みが厚くてゴワゴワ感を有するので、貼付した状態で運動する場合には、貼付している粘着包帯による違和感が大きくなってしまう。また、屋内での運動では問題ないが、屋外での運動などで外部から浸入する水分によって粘着包帯が濡れた場合、伸縮性基布が綿糸からなるような基布では吸水してしまい、積層されている粘着剤層の皮膚接着力の低下や、基布と粘着剤層との間の接着力（投錨力）の低下を招き、時には皮膚面から粘着包帯自体が脱落する場合もあるので、撥水性を有する粘着包帯も望まれている。 As an adhesive bandage using the above stretchable base material, a strong twisted fabric in which 100% cotton yarn is strongly twisted is generally used as a stretchable base fabric, which has excellent fixability at the application site. It is. However, since such an adhesive bandage is relatively thick and has a feeling of tingling, when exercising in a state of being applied, an uncomfortable feeling due to the applied adhesive bandage is increased. In addition, there is no problem in indoor exercise, but when the adhesive bandage gets wet by moisture entering from the outside due to outdoor exercise etc., the base fabric made of cotton yarn absorbs water and is laminated. This reduces the adhesive strength of the adhesive layer and the adhesive strength (throwing force) between the base fabric and the adhesive layer, and sometimes the adhesive bandage itself may fall off from the skin surface. An adhesive bandage having aqueous properties is also desired.
本発明者らは上記のような実情の下、医療衛生材料用途やスポーツ用途において、皮膚面、特に靱帯などの関節部位に貼付することによって関節の動きを制限しながら適度に皮膚の動きに追従して治癒を促進すると共に、外部から水分が浸入して皮膚接着力の低下や、伸縮性基布から粘着剤層の脱落が起こることを防止できる伸縮性粘着包帯を得るべく鋭意検討を行った。その結果、伸縮性布基材を単に編布にするだけでなく特定の編布とし、さらに撥水性プラスチックフィルムおよび粘着剤層を積層する面を布基材の特定面にすることによって上記課題を解決できることを見い出し、本発明を完成するに至った。 In the medical hygiene material use and sports use under the above circumstances, the present inventors appropriately follow the skin movement while restricting the joint movement by applying it to the joint surface such as the ligament on the skin surface. In addition to promoting healing, we intensively studied to obtain a stretchable adhesive bandage that can prevent moisture from entering from the outside and reducing the adhesive strength of the skin and the adhesive layer from falling off the stretchable base fabric. . As a result, the stretch fabric base material is not only a knitted fabric, but also a specific knitted fabric, and the surface on which the water-repellent plastic film and the adhesive layer are laminated is a specific surface of the fabric base material. The inventors have found that this can be solved, and have completed the present invention.
即ち、本発明は、撥水性プラスチックフィルムを片面に積層してなる伸縮性布基材の他面側に粘着剤層が形成され、ロール状に巻回されてなる伸縮性粘着包帯であって、伸縮性布基材が天竺編布であり、繊維ループが表目に現れる表面に撥水性プラスチックフィルムが積層されていることを特徴とする伸縮性粘着包帯を提供するものである。 That is, the present invention is a stretchable adhesive bandage in which a pressure-sensitive adhesive layer is formed on the other side of a stretchable cloth base material formed by laminating a water-repellent plastic film on one side and wound in a roll shape, It is intended to provide an elastic adhesive bandage characterized in that the elastic fabric base material is a woven fabric knitted fabric, and a water-repellent plastic film is laminated on the surface where the fiber loop appears on the surface.
さらに本発明は、上記伸縮性粘着包帯を伸長させて関節部位に貼付する伸縮性粘着包帯の使用方法を提供するものである。 Furthermore, this invention provides the usage method of the elastic adhesive bandage which extends the said elastic adhesive bandage and sticks to a joint site | part.
本発明の伸縮性粘着包帯は、布基材を天竺編布にし、繊維ループが表目に現れる面に撥水性プラスチックフィルムを積層し、他面に粘着剤層を形成することによって、布基材と粘着剤層との接着力（投錨力）や、布基材と撥水性プラスチックフィルムとの接着力に優れるという効果を奏するものである。さらに、この伸縮性粘着包帯は、適度な伸びや引張強度、皮膚面に対する接着力、耐水接着力などを有するので、特に靱帯部位に対する使用において優れた固定性および治癒効果を発揮するものである。 The stretchable adhesive bandage of the present invention has a cloth base material by making a cloth base material into a knitted fabric, laminating a water-repellent plastic film on the surface where the fiber loop appears on the surface, and forming an adhesive layer on the other surface. The adhesive strength (throwing force) between the adhesive layer and the pressure-sensitive adhesive layer and the adhesive strength between the cloth substrate and the water-repellent plastic film are excellent. Furthermore, this stretchable adhesive bandage has appropriate elongation and tensile strength, adhesion to the skin surface, water-resistant adhesion, and the like, and therefore exhibits excellent fixability and healing effect particularly when used on a ligament site.
本発明の伸縮性粘着包帯は、撥水性プラスチックフィルムを片面に積層した伸縮性布基材の他面側に粘着剤層を設け、ロール状に巻回してなる伸縮性粘着包帯である。伸縮性布基材としては、少なくとも長さ方向に伸縮性を有するものであるが、横方向にも伸縮性を有する基材であってもよい。なお、本発明における伸縮性とは、長さ方向（ロール状に巻回する方向）に引っ張って伸長させたのち応力を解放した際に、ほぼ元の長さに戻る性質をいう。具体的には、長さ方向へ引っ張った際の最大伸び率（破断伸び）が２０％以下、定荷重１．０Ｎ／５ｍｍ幅の条件下での長さ方向の伸び率が、５〜１５％、好ましくは１０％程度のものが望ましい。最大伸び率が２０％を超えると、伸縮性の応力の効果がなくなる恐れがあり、上記定荷重下での伸び率が５％に満たない場合は、伸縮性がなくなり、２０％を超えても伸縮性がなくなる傾向を示す。 The stretchable adhesive bandage of the present invention is a stretchable adhesive bandage formed by providing a pressure-sensitive adhesive layer on the other side of a stretchable cloth base material having a water-repellent plastic film laminated on one side and winding it in a roll shape. The stretchable cloth base material has stretchability in at least the length direction, but may be a base material that also has stretchability in the lateral direction. The stretchability in the present invention refers to the property of returning to the original length when the stress is released after being stretched by pulling in the length direction (direction wound in a roll shape). Specifically, the maximum elongation (breaking elongation) when pulled in the length direction is 20% or less and the elongation in the length direction is 5 to 15% under a constant load of 1.0 N / 5 mm width. Preferably, about 10% is desirable. If the maximum elongation exceeds 20%, the effect of stretchable stress may be lost. If the elongation under the above-mentioned constant load is less than 5%, the stretchability is lost, and even if it exceeds 20%. It shows a tendency to lose elasticity.
また、布基材の引張強度（破断強度）は、使用時に粘着包帯にかかる荷重に対する耐久性や操作性の点から、長さ方向で１１０〜１３０Ｎ／１９ｍｍ幅の強度を有するように調整することが好ましい。 In addition, the tensile strength (breaking strength) of the cloth base material should be adjusted to have a strength of 110 to 130 N / 19 mm width in the length direction from the viewpoint of durability and operability with respect to the load applied to the adhesive bandage during use. Is preferred.
上記本発明の伸縮性粘着包帯に用いる布基材は、上記した伸縮性を発揮するために天竺編布とする必要がある。天竺編布とは丸編みの中の一つの編み方であり、図1に示すように、編み糸がループ状になると共に、一方の面にループの表目が現れていることが特徴である。本発明では天竺編みの編布を用いることによって、後述する撥水性プラスチックフィルムや粘着剤層を積層するに際して、投錨力が強く強固に接着することができるので、靱帯などの関節部位に貼付使用した場合、優れた固定性を発揮することができるものである。 The cloth base material used for the stretchable adhesive bandage of the present invention needs to be a tentacle knitted fabric in order to exhibit the stretchability described above. Tendon knitted fabric is a method of knitting in circular knitting. As shown in Fig. 1, the knitting yarn has a loop shape and a loop surface appears on one side. . In the present invention, by using a knitted woven fabric of tenjitsu, when laminating a water-repellent plastic film and an adhesive layer, which will be described later, the anchoring force can be strongly and firmly adhered, so that it is used by being stuck to a joint site such as a ligament. In this case, excellent fixability can be exhibited.
上記布基材を構成する編み糸（経糸および緯糸）の材質としては、特に限定されるものではなく、ポリエステルやポリウレタン、ポリアミド、ビニロン、ポリエチレン、ポリプロピレンなどからなるプラスチック繊維を用いることができるが、これらのうち、耐水性（撥水性）を付与するためには機械的強度が大きく低吸水性繊維であるポリエステル繊維を用いることが好ましいものである。 The material of the knitting yarn (warp and weft) constituting the cloth base material is not particularly limited, and plastic fibers made of polyester, polyurethane, polyamide, vinylon, polyethylene, polypropylene, or the like can be used. Among these, in order to impart water resistance (water repellency), it is preferable to use polyester fibers having high mechanical strength and low water absorption fibers.
さらに経糸や緯糸としての繊維の太さは、布基材に付与する通気性や伸縮性などの観点から、適宜設定することができるが、機械的強度の維持、適度な水分輸送能、布基材と粘着剤層との密着性なども考慮して設定することが好ましい。なお、布基材の厚さは限定されるものではないが、貼付操作性と貼付時の違和感の防止のバランスからは２０〜５０μｍ、好ましくは２０〜３０μｍ程度の厚みに調整することが望ましい。 Furthermore, the thickness of the fiber as the warp or weft can be set as appropriate from the viewpoints of air permeability and stretchability imparted to the fabric base material. However, maintenance of mechanical strength, appropriate water transport capability, fabric base It is preferable to set in consideration of the adhesion between the material and the pressure-sensitive adhesive layer. In addition, although the thickness of the cloth base material is not limited, it is desirable to adjust to a thickness of about 20 to 50 μm, preferably about 20 to 30 μm, from the balance of application operability and prevention of uncomfortable feeling during application.
本発明の伸縮性粘着包帯における上記布基材の片面には、撥水性プラスチックフィルムが積層されている。本発明において撥水性プラスチックフィルムは布基材の何れの面に形成してもよいのではなく、天竺編みされた布基材において繊維ループが表目に現れる表面に形成する必要がある。つまり、繊維ループが表目に現れる面（図1において手前面側）に撥水性プラスチックフィルムを形成することによって、撥水性プラスチックフィルムを形成した後の表面が平滑となり、関節部位へ巻き付け貼付した際の自背面接着性が良好となるのである。 A water-repellent plastic film is laminated on one side of the cloth base material in the stretchable adhesive bandage of the present invention. In the present invention, the water-repellent plastic film may not be formed on any surface of the cloth base material, but needs to be formed on the surface where the fiber loop appears on the front surface of the cloth base material knitted. In other words, by forming a water-repellent plastic film on the surface where the fiber loop appears on the front surface (the front side of the hand in Fig. 1), the surface after the water-repellent plastic film is formed becomes smooth and is wrapped around and pasted to the joint site. This is because the self-back surface adhesiveness is improved.
なお、撥水性プラスチックフィルムと布基材との接着力を向上せるためには、数μｍ厚程度のバインダー層を介在させることが好ましい。バインダー層を構成する材料としては、バインダー効果を有するものであれば特に制限されないが、布基材の伸縮性を阻害しないためには、ポリエーテルポリウレタンやポリエステルポリウレタンなどのウレタン樹脂系のバインダーを用いることが好ましい。 In order to improve the adhesive force between the water-repellent plastic film and the cloth substrate, it is preferable to interpose a binder layer having a thickness of about several μm. The material constituting the binder layer is not particularly limited as long as it has a binder effect, but a urethane resin binder such as polyether polyurethane or polyester polyurethane is used in order not to inhibit the stretchability of the cloth base material. It is preferable.
このような撥水性プラスチックフィルムの材質としては、ポリウレタンやポリエチレン、ポリプロピレン、ポリアミド、ポリエステルなどを用いることができるが、前記した伸縮性布基材の伸縮性に追従するためには、撥水性を有すると共に適度な弾性を有するポリウレタンを用いることが好ましい。ポリウレタンフィルムは伸縮性布基材を水濡れから保護すると共に、布基材のキックバック性を強化しており、厚さに応じてキックバック性を調節することが可能であるので、テーピング用途に好適なものである。 As a material for such a water-repellent plastic film, polyurethane, polyethylene, polypropylene, polyamide, polyester, or the like can be used. However, in order to follow the stretchability of the stretchable cloth substrate, it has water repellency. At the same time, it is preferable to use polyurethane having moderate elasticity. The polyurethane film protects the stretchable cloth base material from wetness and enhances the kickback property of the cloth base material. The kickback property can be adjusted according to the thickness. Is preferred.
このような撥水性プラスチックフィルムの厚さは、５〜３０μｍ、好ましくは５〜２０μｍとすることが望ましい。撥水性プラスチックフィルムの厚さが５μｍに満たない場合は、皮膚面へ貼付した際に伸縮性布基材と共に伸長した際に、撥水性プラスチックフィルムが薄すぎるので破断して撥水効果が低下する恐れがある。また、厚さが３０μｍを超える場合には、粘着包帯全体の腰が強くなりすぎて、粘着包帯を皮膚面に貼付使用した際に使用者に違和感を与えたり、キックバック性が強くなりすぎて貼付部位への締め付けが強くなり、皮膚へのストレス刺激を生じさせる恐れがある。 The thickness of such a water-repellent plastic film is 5-30 μm, preferably 5-20 μm. When the thickness of the water-repellent plastic film is less than 5 μm, when the film is stretched together with the stretchable cloth base material when applied to the skin surface, the water-repellent plastic film is too thin and breaks, resulting in a reduced water-repellent effect. There is a fear. In addition, when the thickness exceeds 30 μm, the entire adhesive bandage becomes too strong, and when the adhesive bandage is applied to the skin surface, the user feels uncomfortable or the kickback property becomes too strong. Tightening to the application site becomes strong, and there is a risk of causing stress stimulation to the skin.
また、撥水性プラスチックフィルムをポリウレタンフィルムにした場合には、ポリウレタン樹脂自体の化学的性質により透湿性を付与することができる。このため、上記の厚み範囲のポリウレタンフィルムを積層した場合には、撥水性プラスチックフィルムと布基材とを積層した状態での透湿度は、温度４０℃、相対湿度２０％の条件下においては、透湿度が１０００〜３０００ｇ／ｍ２・２４ｈ程度を維持することができる。さらに、これに後述する粘着剤層を形成して粘着包帯とした場合の全体の透湿度は、温度４０℃、相対湿度２０％において、２００ｇ／ｍ２・２４ｈ以上であり、好ましくは５００ｇ／ｍ２・２４ｈ以上を示すものである。 When the water repellent plastic film is a polyurethane film, moisture permeability can be imparted by the chemical properties of the polyurethane resin itself. For this reason, when the polyurethane film having the above thickness range is laminated, the moisture permeability in the state where the water-repellent plastic film and the cloth base material are laminated is 40 ° C. and 20% relative humidity. The moisture permeability can be maintained at about 1000 to 3000 g / m 2 · 24 h. Furthermore, when the pressure-sensitive adhesive layer described later is formed to form an adhesive bandage, the overall moisture permeability is 200 g / m 2 · 24 h or more at a temperature of 40 ° C. and a relative humidity of 20%, preferably 500 g / m. It indicates 2 · 24h or more.
本発明の伸縮性粘着包帯は、上記した布基材における撥水性プラスチックフィルム積層面と反対の面に粘着剤層を形成したものである。この粘着剤層は本発明の伸縮性粘着包帯を皮膚面に粘着固定できるだけの充分な接着力を有すると共に、布基材の伸縮や貼付部位の皮膚面の動きに対しても充分に追従できるだけの接着力を有するものであればよい。具体的には、室温下で対ベークライト板に対する接着力試験（ＪＩＳＺ０２３７に準じる）において、２〜８Ｎ／１９ｍｍ幅、好ましくは、３〜６Ｎ／１９ｍｍ幅の接着力を発揮するものが望ましい。 The stretchable pressure-sensitive adhesive bandage of the present invention is obtained by forming a pressure-sensitive adhesive layer on the surface opposite to the water-repellent plastic film laminated surface in the above-described cloth base material. This pressure-sensitive adhesive layer has sufficient adhesive strength to allow the elastic adhesive bandage of the present invention to be adhesively fixed to the skin surface, and can also sufficiently follow the expansion and contraction of the cloth base material and the movement of the skin surface of the application site. Any material having adhesive strength may be used. Specifically, it is desirable to exhibit an adhesive force of 2 to 8 N / 19 mm width, preferably 3 to 6 N / 19 mm width in an adhesive strength test (according to JISZ0237) against a bakelite plate at room temperature.
このような接着力を発揮する粘着剤としては、特に限定されないが、アクリル酸エステル系粘着剤、天然ゴム系粘着剤、合成ゴム系粘着剤、シリコーン系粘着剤、ビニルエーテル系粘着剤などを用いることができ、これらのうち皮膚面に対する粘着特性の調整が容易であることや、低皮膚刺激性であることなどから、アクリル酸エステル系粘着剤を用いることが好ましい。具体的には、（メタ）アクリル酸アルキルエステルを主成分単量体として、これに必要に応じて共重合可能な単量体を共重合させ、さらに必要に応じて各種架橋剤による化学的架橋や、電子線や紫外線などの放射線照射による物理的架橋を施したアクリル酸エステル系粘着剤を用いることが好ましい。 The pressure-sensitive adhesive exhibiting such adhesive force is not particularly limited, but acrylic acid-based pressure-sensitive adhesives, natural rubber-based pressure-sensitive adhesives, synthetic rubber-based pressure-sensitive adhesives, silicone-based pressure-sensitive adhesives, vinyl ether-based pressure-sensitive adhesives, and the like are used. Among these, it is preferable to use an acrylate-based pressure-sensitive adhesive because it is easy to adjust the adhesive properties to the skin surface and has low skin irritation. Specifically, (meth) acrylic acid alkyl ester is used as a main component monomer, and a copolymerizable monomer is copolymerized as necessary, and chemical crosslinking with various crosslinking agents as necessary. Alternatively, it is preferable to use an acrylic ester pressure-sensitive adhesive that has been physically cross-linked by irradiation with an electron beam or ultraviolet radiation.
アクリル酸エステル系粘着剤の主成分単量体として用いる（メタ）アクリル酸アルキルエステルとしては、炭素数２〜１２のアルキル基を有する（メタ）アクリル酸アルキルエステルを４０〜９９重量％、好ましくは４０〜６０重量％の範囲で用いることができ、共重合可能な単量体としては、（メタ）アクリル酸などのカルボキシル基含有単量体、（メタ）アクリル酸２−ヒドロキシエチルエステルなどのヒドロキシル基含有単量体、（メタ）アクリル酸２−メトキシエチルエステルなどのアルコキシル基含有単量体、２−ビニルピロリドンなどの酸アミド基含有単量体のほか、酢酸ビニルやアミノ基含有単量体などを、目的に応じて適宜一種以上選択して６０重量％以下、好ましくは１〜６０重量％の範囲で共重合させることができる。 The (meth) acrylic acid alkyl ester used as the main monomer of the acrylic ester-based pressure-sensitive adhesive is 40 to 99% by weight of a (meth) acrylic acid alkyl ester having an alkyl group having 2 to 12 carbon atoms, preferably It can be used in the range of 40 to 60% by weight, and examples of the copolymerizable monomer include carboxyl group-containing monomers such as (meth) acrylic acid and hydroxyl such as (meth) acrylic acid 2-hydroxyethyl ester. In addition to group-containing monomers, alkoxyl group-containing monomers such as (meth) acrylic acid 2-methoxyethyl ester, acid amide group-containing monomers such as 2-vinylpyrrolidone, vinyl acetate and amino group-containing monomers Can be copolymerized in the range of 60% by weight or less, preferably 1-60% by weight.
布基材の片面に形成する上記粘着剤層の厚さは、貼付する皮膚面の動きへの追従性や固定性などを考慮して適宜決定されることが好ましいが、例えば、１０〜１８０μｍ、好ましくは１５〜１５０μｍ、さらに好ましくは２０〜８０μｍ程度に設定することが望ましい。また、粘着剤層は布基材全面に設けられていてもよいし、粘着剤層形成部をドット状や条状、格子などのパターン状に設けていてもよい。条状に設ける場合は、通気路として機能する空間が確保されていれば特に限定されることはないが、例えば、直線状や波状、山状、鋸歯状、これらを組み合わせた形状などが挙げられる。これらのうち、皮膚接着力の確保や端縁部の捲れ防止などの点から波状に粘着剤層を形成することが好ましい。 The thickness of the pressure-sensitive adhesive layer formed on one side of the cloth base material is preferably determined appropriately in consideration of the followability to the movement of the skin surface to be applied, fixability, etc., for example, 10 to 180 μm, The thickness is preferably set to 15 to 150 μm, more preferably about 20 to 80 μm. The pressure-sensitive adhesive layer may be provided on the entire surface of the cloth base material, or the pressure-sensitive adhesive layer forming portion may be provided in a pattern shape such as a dot shape, a stripe shape, or a lattice. When it is provided in a strip shape, it is not particularly limited as long as a space functioning as an air passage is secured, but examples thereof include a straight shape, a wave shape, a mountain shape, a sawtooth shape, and a combination of these. . Among these, it is preferable to form the pressure-sensitive adhesive layer in a wave shape from the viewpoints of securing the skin adhesive force and preventing the edge portion from squeezing.
本発明の伸縮性粘着包帯は、上記のような構成からなるものであるが、皮膚面に貼付した場合、貼付部位に蒸れなどが生じて皮膚刺激を発現する可能性がある場合は、撥水性プラスチックフィルムおよび伸縮性布基材に穿孔処理を施して、通気性を確保することが好ましい。なお、上記したように粘着剤層をパターン状に形成することを併用すると、粘着包帯全体が優れた通気性を有するようになるので、さらに好ましいものとなる。 The stretchable adhesive bandage of the present invention has the above-described configuration. When it is applied to the skin surface, the skin may become stuffy and cause skin irritation. It is preferable to perforate the plastic film and the stretchable cloth base material to ensure air permeability. In addition, when it uses together forming an adhesive layer in pattern shape as mentioned above, since the whole adhesive bandage will have the outstanding air permeability, it becomes a more preferable thing.
本発明の伸縮性粘着包帯は、上記のような構成からなるものであり、粘着剤層面を内側にして自背面に粘着剤層が接着するようにロール状に巻回するか、必要に応じて粘着剤層の表面に剥離シートを積層して粘着面を被覆保護したものをロール状に巻回して最終製品として使用に供するものである。 The elastic pressure-sensitive adhesive bandage of the present invention has the above-described configuration, and is wound in a roll shape so that the pressure-sensitive adhesive layer adheres to the back surface with the pressure-sensitive adhesive layer surface inside, or as necessary. A product obtained by laminating a release sheet on the surface of the pressure-sensitive adhesive layer and covering and protecting the pressure-sensitive adhesive surface is wound into a roll and used as a final product.
剥離シートとしては、一般的に皮膚へ貼付する医療用の粘着テープなどに用いられるものを使用することができる。具体的には、上質紙やグラシン紙、パーチメント紙などの表面に、シリコーン樹脂やフッ素樹脂などの剥離性能を有する剥離剤をコーティング処理したものや、上質紙にレジンをアンカーコートしたもの、またはポリエチレン樹脂などをラミネートした基材の表面にシリコーン樹脂やフッ素樹脂などの剥離性能を有する剥離剤をコーティング処理したものを使用することができる。 As the release sheet, those generally used for medical adhesive tapes to be attached to the skin can be used. Specifically, the surface of high-quality paper, glassine paper, parchment paper, or the like is coated with a release agent having a release performance such as silicone resin or fluororesin, or the high-quality paper is anchor-coated with resin, or polyethylene The surface of the base material laminated with a resin or the like can be used in which a release agent having a release performance such as silicone resin or fluororesin is coated.
