噴霧用組成物に成分(c)を含有しない以外は、実施例1と同様にして、静電スプレー工程を行い、繊維の堆積物からなる被膜を得た。
噴霧用組成物に成分(c)を含有せず、成分(a)を実施例1に用いたエタノールに1-ブタノール( 和光純薬工業(株)社製:商品名 1Butanol)を更に加えたものに変更し、成分(b)を(アクリル酸アルキル・オクチルアクリルアミド)コポリマー(Akzonobel社製:商品名DERMACRYL 79)に変更する以外は、実施例1と同様にして、静電スプレー工程を行い、繊維の堆積物からなる被膜を得た。
実施例及び比較例で形成された被膜について、皮膚との密着性、被膜の外観を、以下の基準で評価した。その結果を表1に示す。
1:静電スプレー工程での紡糸直後から被膜がほぼすべて剥離する。
2:静電スプレー工程での紡糸直後では被膜が貼り着くが、静止状態30分後に被膜面積の50%以上が剥離する。
3:静電スプレー工程での紡糸直後では被膜が貼り着くが、静止状態30分後に被膜面積の50%未満が剥離する。
4:静電スプレー工程での紡糸後、静止状態で30分間は被膜が貼り着くが、指で平行方向に剪断力を与えると剥離する。
5:静電スプレー工程での紡糸後、静止状態で30分間は被膜が貼り着き、指で平行方向に剪断力を与えても剥離しない。
1:被膜の外観が白く見える。
2:被膜の外観が白に近い半透明に見える。
3:被膜の外観が半透明に見える。
4:被膜の外観が薄い半透明に見える。
5:被膜の外観が透明に見える。
実施例3の噴霧用組成物を用いて、実施例1の静電スプレー工程にて、以下に示す対象物(d)及び(e)に静電スプレー法を5秒間行った。付着してから30秒経過後の繊維の堆積物からなる被膜を得た。
(d)手のひら
(e)100mm×100mm×10mmのアルミ金属板表面
実施例7の噴霧用組成物を用いて、実施例12と同様にして静電スプレー工程を行い繊維の堆積物からなる被膜を得た。
噴霧用組成物における成分(a)、(b)、(c)を、以下の表1に示す条件とした以外は実施例12と同様にして、静電スプレー工程を行い、繊維の堆積物からなる被膜を得た。
比較例1の噴霧用組成物を用いて、実施例1の静電スプレー工程にて、実施例12と同様にして、静電スプレー工程を行い、繊維の堆積物からなる被膜を得た。
対象物(d)と(e)に静電スプレーして30秒間付着させた後に、被膜を剥がし、走査型電子顕微鏡(SEM)観察によって、繊維径を直接読み取ることで平均繊維径を得た。繊維の太さは、走査型電子顕微鏡(SEM)観察によって、繊維を10000倍に拡大して観察し、その二次元画像から欠陥(繊維の塊、繊維の交差部分、液滴)を除き、繊維を任意に10本選び出し、繊維の長手方向に直交する線を引き、繊維径を直接読み取ることで測定した。(1)式を満たす場合は皮膚との密着性や被膜の外観が良好となり、(2)式を満たす場合は皮膚と密着しにくく、外観も白く不自然な状態であった。結果を表2に示す。
(d)の平均繊維径>(e)の平均繊維径・・・(1)
(d)の平均繊維径≦(e)の平均繊維径・・・(2)
表3、表4に示す噴霧用組成物について、実施例1と同様にして、静電スプレー工程を行い、繊維堆積物からなる被膜を得た。実施例1と同様にして、皮膚との密着性、被膜の外観の評価と、下記の被膜の感触の評価を行った。評価結果を表3及び表4に示す。
実施例15~実施例28の被膜について、被膜形成後30分後の被膜を指で押したときの感触を以下の評価基準により評価した。評価は3名で行い、協議の結果を表3に示す。
1:べとべとする
2:ややべとつく
3:しっとりした感触
4:なめらか
5:すべるようになめらか
―:密着性の評価が5未満
表5に示す実施例26、28の被膜は、皮膚との密着性が高くしっとりした感触の被膜であるが、ややタック力があり、成分(b)が完全に乾燥せずにタック力が発現したことによる感触であると考えられる。一方、成分(b)に対して成分(c)の含有量が多い実施例27の被膜は、皮膚との密着性が高くややべとつく感触であり、成分(c)に由来するべとつきであると考えられる。
粘度の測定条件は、噴霧組成物を調製後1日25℃にて保存後、25℃において、E型粘度計(VisconicEMD、東京計器株式会社製)により、ローターNo.43を用い、回転数は1280mPa・s以上の場合は1rpm、128mPa・s以上1280mPa・s未満の場合は10rpm、128mPa・s未満の場合は100rpmとした。
表6に記載の噴霧組成物について、実施例1と同様にして、静電スプレー工程を行い、繊維堆積物からなる被膜を得た。実施例1と同様にして、被膜の外観の評価を行った。評価結果を表6に示す。
