<P>PROBLEM TO BE SOLVED: To provide a nanofiber sheet that shrinks by contact with water. <P>SOLUTION: A nanofiber sheet of this invention includes nanofibers containing a water-soluble high polymer and a water-insoluble high polymer, and shrinks by contact with water. Preferably the proportion of the water-soluble high polymer in the nanofiber sheet is 30-90 mass%. Preferably the water-soluble high polymer and the water-insoluble high polymer are intermingled in the nanofibers. <P>COPYRIGHT: (C)2012,JPO&INPIT |
