COMPOSITE SHEET FOR ABSORBENT ARTICLES
Document Type and Number:
WIPO Patent Application WO/2017/002484
Kind Code:
A1
Abstract:
The present invention provides a composite sheet which is so configured that moisture such as sweat present on one surface side of the composite sheet can be transferred to the other surface side and can be evaporated without retaining the moisture on the above-mentioned one surface side so that the moisture content on the above-mentioned one surface side can be reduced and almost all of the moisture cannot be retained by a sheet that forms the above-mentioned one surface. The present invention relates to a composite sheet 1 which has a first surface (F1) and a second surface (F2) that is located on the opposite side of the first surface, and which has a hydrophobic non-woven fabric (2A) that forms the first surface and a hydrophilic non-woven fabric (2B) that forms the second surface. In the composite sheet according to the present invention, a concavo-convex structure is formed on at least the hydrophilic non-woven fabric among the hydrophobic non-woven fabric and the hydrophilic non-woven fabric, and the hydrophobic non-woven fabric and the hydrophilic non-woven fabric are in direct contact with each other at least partially.
