Title:
STRETCH SHEET, ADHESIVE SKIN PATCH AND PROCESS FOR PRODUCING THEM
Document Type and Number:
WIPO Patent Application WO/2006/080246
Kind Code:
A1
Abstract:
A nonwoven fabric that due to having of appropriate drape at the time of attachment or pasting, excels in handling easiness when used as a base cloth of adhesive skin patch, etc., and that after initiation of use, excels in elongation recovery, realizing enhanced softness and high follow property and is relieved in stiffness feeling. There is provided a stretch sheet of 20 to 200 g/m2 basis weight characterized in that the breaking elongation thereof in at least one direction is ≥ 100%, and that the tensile stress at 10% elongation measured upon a procedure consisting of first performing an elongation deformation as large as ≥ 20%, thereafter removing the deformation load and once more performing elongation is in the range of 3 to 85% based on the initial value prior to the large deformation.
