A stretchable absorbent composite having a Composite Permeability of about 10 Darcy or more, or about 15 Darcy or more, and Composite Stretchability of about 30% or more, or about 50% or more, or about 100% or more, and a method of making such a stretchable absorbent composite. The stretchable absor
A stretchable absorbent composite having a Composite Permeability of about 10 Darcy or more, or about 15 Darcy or more, and Composite Stretchability of about 30% or more, or about 50% or more, or about 100% or more, and a method of making such a stretchable absorbent composite. The stretchable absorbent composite includes a superabsorbent material, an elastomeric material, and, optionally, pulp fibers. More particularly, the stretchable absorbent composite may include between about 30% and about 85% by weight superabsorbent material, between about 5% and about 25% by weight elastomeric material, and between about 10% and about 70% by weight pulp fibers. The stretchability and liquid handling abilities of the stretchable absorbent composite renders the stretchable absorbent composite suitable for incorporation into a variety of absorbent articles, including personal care products, health/medical absorbent articles, and household/industrial absorbent articles, for example.
