Title:
LAMINATED SHEET, AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/004834
Kind Code:
A1
Abstract:
Disclosed is a laminated sheet which is composed of non-woven fiber assemblies. The laminated sheet comprises: a liquid-retaining layer which can absorb a liquid component; and an adhesive layer which is formed on at least one surface of the liquid-retaining layer and can be penetrated with the liquid component and with which the skin is to be contacted. The adhesive layer comprises non-woven fiber assemblies having a number average fiber diameter of 10 μm or less, and the ratio of the thickness of the adhesive layer to the thickness of the liquid-retaining layer (i.e., an (adhesive layer)/(liquid-retaining layer) ratio) of 1/4 to 1/100. The adhesive layer may be composed of non-woven fiber assemblies in which the standard deviation of the fiber diameters is 5 or less. The liquid-retaining layer may be composed of non-woven fabric fiber assemblies having larger fiber diameters than those of the fibers that constitute the adhesive layer. The laminated sheet has an excellent balance between liquid-retaining properties and liquid-releasing properties, and also has excellent adhesiveness and fitting properties to the skin when the laminated sheet is impregnated with a liquid component.
