マイクロカプセル保持領域11では、粘着性を有する接着剤が、機能性組成物を構成するマイクロカプセルを保持している。
なお、図3は、本開示の実施形態の1つに従う吸収性物品の製造方法を説明するための図であり、具体的には、図1及び図2に示される吸収性物品の製造方法を説明するための図である。また、図4は、機能性組成物塗布機102を用いて、トップシート2を、機能性組成物で塗布する工程の拡大斜視図である。
液透過性層、液不透過性層及び吸収層は、当技術分野で公知の材料により形成されうるが、液不透過性層は、機能性組成物の溶媒を保持する観点から、不織布であることが好ましい。
上記塗布すべき層としては、液透過性層及び吸収層とが挙げられ、上記塗布すべき面としては、液透過性層の非肌当接面及び吸収層の液透過性層側面が挙げられる。
なお、本明細書において、塗布すべき層及び塗布すべき面の対象(塗布すべきもの)は、機能性組成物である。
上記接触型塗工機としては、ロール型塗工機、スリット型塗工機、ディップ型塗工機、ビード型塗工機、フレキソ型塗工機、グラビア型塗工機が挙げられる。
上記接着剤塗布領域は、液透過性層及び吸収層の間と、吸収層及び液不透過性層の間との任意の位置に形成されうる。
また、吸収性物品が、液透過性層及び吸収層の間の補助シート層を含む場合には、上記接着剤塗布領域は、液透過性層及び補助シート層の間と、補助シート層及びきゅうしゅう層の間との任意の位置に形成されうる。
本開示の製法では、上記接着剤塗布領域を形成する接着剤としては、当技術分野で公知の接着剤、例えば、ホットメルト接着剤が挙げられる。
なお、塗布すべき層の厚さは、株式会社大栄科学精器製作所製のFS-60DS(測定子:15cm2,測定荷重:3gf/cm2)を用いて測定される。具体的には、20℃の恒温室で24時間静置した塗布すべき層の厚さを、FS-60DSで5カ所測定し、その平均値を厚さとして採用する。
上記坪量は、20℃の恒温室で24時間静置した塗布すべき層の質量を、面積で除することにより算出される。
上記厚さは、上述の通り測定される。
また、液透過性層の非肌当接面にマイクロカプセル保持領域が存在する場合には、液透過性層を通過した液体をすばやくマイクロカプセルに到達させることができるため、少ない液体量で第1機能性成分を放出させることができる。
吸収性物品が接着領域を有することにより、使用時に、吸収性物品がよれにくくなる。
なお、本明細書において、接着領域が機能性組成物を構成する溶媒を含まないとは、接着領域を構成する接着剤が、上記溶媒を0~5質量%の量で含むことを意味する。
機能性組成物塗布領域を形成するステップと、接着剤塗布領域を形成するステップは、どちらを先に実施してもよい。
トップシートロール101から巻きだした、帯状のトップシート2の吸収体が積み重ねられる面(非肌当接面)に、機能性組成物塗布機102から機能性組成物を塗布し、トップシート2の上に、機能性組成物塗布領域8(8'及び8'')を形成する。ついで、接着剤塗布機103から接着剤を塗布し、トップシート2の上に、機能性組成物塗布領域8(8'及び8'')を間に挟んで、3つの接着剤塗布領域9(9',9''及び9''')を形成する。
バックシートロール121から巻きだした、帯状のバックシート3に、接着剤塗布機122から接着剤を塗布し、エンボス部7が形成された積み重ね物109に積み重ね、積み重ね物123を形成する。次いで、積み重ね物123を、一対のエンボスロール131にて、吸収性物品の形状にラウンドエンボスし、そしてカッター141で吸収性物品の形状にカットし、吸収性物品1を製造する。
なお、補助シートの素材としては、トップシートと同様のもの、例えば、不織布が挙げられる。
また、上記機能性組成物は、上記溶媒に溶解した、揮発性を有する第2機能性成分をさらに含むことができる。
なお、本明細書では、マイクロカプセルに内包される機能性成分を、第2機能性成分と区別するため、「第1機能性成分」と称する場合がある。
また、本明細書では、第1機能性成分及び/又は第2機能性分を、単に「機能性成分」と称する場合がある。
なお、芳香機能を有する機能性成分を、芳香成分と称する場合がある。
上記スキンケア機能としては、例えば、消炎機能、鎮痒機能、かぶれ防止機能、保湿機能等が挙げられ、そして上記スキンケア機能を有する機能性成分としては、例えば、メントール、サリチル酸メチル等が挙げられる。
上記揮発性は、機能性成分が発揮すべき機能によって、その好ましい蒸気圧は異なるが、第1機能性成分及び第2機能性成分は、例えば、25℃及び1気圧において、好ましくは30Pa以上、より好ましくは50Pa以上、そしてさらに好ましくは70Pa以上の蒸気圧を有する。上記蒸気圧が低すぎると、所望の機能を発揮しにくくなる傾向があり、そして上記蒸気圧が高すぎると、ユーザーが吸収性物品を使用するまでの間に、機能性成分が揮発し、その量が減少する傾向、着用者の皮膚に過度の機能を発揮する等の場合がある。
上記マイクロカプセルの水崩壊性の度合いは、液体と接した後、第1機能性成分をどのように放出させるかによって異なり、例えば、液体と接した後に第1機能性成分を速やかに放出させるためには、上記水崩壊性が高いことが好ましく、そして第1機能性成分を徐放させるためには、上記水崩壊性が低いことが好ましい。
上記水溶解度は、試験温度を25℃にした以外は、OECDガイドラインNo.105フラスコ法に従って測定される。
例えば、上記マイクロカプセルは、25℃において、マイクロカプセルの分散媒である溶媒100gに対して、好ましくは1.0g以下、より好ましくは0.5g以下、そしてさらに好ましくは0.1g以下の溶媒溶解度を有する。
また、上記マイクロカプセルはまた、水にマイクロカプセルの素材を溶解させて水溶液を形成し、当該水溶液に第1機能性成分及び界面活性剤を混合し、上記水溶液をスプレーしながら減圧乾燥することにより製造することができる。
なお、マイクロカプセルを分散させる溶媒は、後述のマイクロカプセルに内包されうる第2溶媒と区別するために、第1溶媒と称される場合がある。
上記溶媒は、親油性の観点からは、後述のIOBが、0.00以上且つ好ましくは1.0以下、より好ましくは0.8以下、そしてさらに好ましくは0.6以下である。
IOB=無機性値/有機性値
により算出される値を意味する。
藤田氏による、主要な基の有機性値及び無機性値を、下記表1にまとめる。
上記動粘度は、JIS K 2283:2000の「5.動粘度試験方法」に従って、キャノンフェンスケ逆流形粘度計を用いて、40℃の試験温度で測定する。
上記炭化水素系溶媒の例としては、例えば、流動パラフィンが挙げられ、そして上記エステル系溶媒の例としては、ミリスチン酸イソプロピルが挙げられる。
上記溶媒が体液滑性付与剤を含むことにより、長時間にわたり、液透過性層に到達した体液等を、吸収体の内部に迅速に滑落させることができる。
ユーザーが吸収性物品を開封すると、上記溶媒(第1溶媒)に溶解した第2機能性成分が揮発し、ユーザーに第2機能性成分の機能が付与される。例えば、第2機能性成分が芳香成分である場合には、ユーザーが周囲に漂う芳香を感じることができる。
例えば、吸収性物品に含まれる第2機能性成分の量を増やすこと、蒸気圧の高い第2機能性成分を選択すること等により、第2機能性成分を、短時間に高い濃度で周囲に放出することができる。
一方、例えば、蒸気圧の低い第2機能性成分を選択することにより、第2機能性成分を、長時間にわたり周囲に放出させることができる。
第2溶媒としては、第1溶媒と同様のものが挙げられる。
なお、機能性組成物中の第1機能性成分の量は、第1機能性成分の機能等によって異なるが、一般的には、上記機能性組成物は、第1機能性成分を、好ましくは0.01~30質量%、より好ましくは0.05~20質量%、そしてさらに好ましくは1~15質量%の比率で含む。
また、第1機能性成分及び第2機能性成分を、それぞれ、同一の香料成分から選択し、そしてその量を変えることにより、香りにアクセントを付けることができる。例えば、液体を吸収する前は、第2機能性成分に由来するほのかな香りが漂い、そして液体を吸収した後は、第1機能性成分に由来する、液体を吸収する前よりも強い同一の香りを漂わせることができる。
また、第1機能性成分として、消臭成分、又は香料成分、好ましくは香りの強度の高い香料成分を採用することにより、機能性成分を香りのマスキング材として用いることができる。
[実施例1]
第1機能性成分を内包するマイクロカプセルとして、Symrise社製のINCAP MENTHOL/IPMを準備した。INCAP MENTHOL/IPMは、第1機能性成分として、冷感成分(メントール)を含有し、そしてマイクロカプセルの素材は、材質変性デンプンであった。
第2機能性成分としての香料成分を含有する溶媒を準備した。上記溶媒は、IPM(ミリスチン酸イソプロピル)であった。
上記マイクロカプセルと、溶媒とを、50:50の質量比で混合することにより、機能性組成物No.1を準備した。
なお、機能性組成物塗布領域において、機能性組成物の坪量は、4g/m2であった。
