Claim 5:
6. A preparation method of the super absorbent polymer non-woven fabric of claim 1, comprising:
preparing a first aqueous polymer solution containing a hydrogel polymer by polymerizing an aqueous monomer solution containing an acrylic acid-based monomer having at least partially neutralized acidic groups, a comonomer having a glass transition temperature (Tg) of room temperature (25° C.) or lower, and a polymerization initiator,
mixing the first aqueous polymer solution with a cross-linking agent having a glass transition temperature (Tg) of room temperature (25° C.) or lower to prepare a second aqueous polymer solution;
spinning the second aqueous polymer solution by a solution blown process; and
drying the spun second aqueous polymer solution to prepare the super absorbent polymer non-woven fabric comprising the super absorbent polymer fibers.
