Abstract
The present disclosure relates to a super absorbent polymer film having excellent moisture absorption and to an absorbent article excellent in feeling capable of reducing skin rashes and other irritations generated when warmed by the wearer's body by including the super absorbent polymer film to improve external dampness. The absorbent article includes the super absorbent polymer film in addition to the absorbent material, so that dampness from the outside is remarkably reduced.
Claims9
A super absorbent polymer film, which is a single layer, and has a thickness of 10 TO 200 μm and a moisture absorption of 10 to 100 g/m2 measured according to KS F 2611 standard,
- wherein the super absorbent polymer film is prepared by a preparation method including the steps of:
- preparing a monomer composition by mixing an acrylic acid-based monomer having at least partially neutralized acidic groups, a cellulose-based thickener, a moisturizing agent, an internal cross-linking agent, a polymerization initiator, and a solvent;
- casting the monomer composition on a substrate;
- polymerizing the monomer composition by irradiating heat and/or light to form a hydrogel polymer, wherein drawing is performed during the polymerizing;
- and drying the hydrogel polymer film.
