Abstract
Description
PEOは、使用者の体内に放出される蚕の繭、医薬品、活性成分、及び/又は殺菌性物質の前処理及び処理の間には、決して使用されない。
図1〜図2Bを参照して、本発明の一態様を説明する。創傷被覆用具1は、吸収剤層4,及び前述した特徴をもつフィブロインのナノ繊維で製造された創傷接触層を備えている。フィブロイン層は、創傷7と接触している。フィブロインナノ繊維の層2の一部、通常は周辺部分は、使用者の皮膚3とも接触している。
a.純正フィブロインメッシュを、室温、穏やかな攪拌条件下で、CaCl2、及び蟻酸と接触させて、可溶性にする。
b.工程(a)で得た粘稠溶液を、適当な容器に注ぎ、放置して残留蟻酸を気化させる。
c.工程(b)のフィブロイン及びCaCl2の混合物を、CaCl2から精製して、フィブロインフィルムを得る。
d.工程(c)のフィルムを剥離し、放置乾燥させる。
e.フィルムを、穏やかな攪拌条件下、蟻酸で処理し、フィブロインとび蟻酸の溶液を、シリンジに移し、静電紡糸する。
