A method of making mutually-reinforced elastic strand/film composites and laminates in which film breakage, strand breakage, and strand alignment problems are minimized or avoided. The method includes casting an elastomeric adhesive film onto a chill roll, extruding elastic strands onto the film while the film is on a chill roll, and stretching the film and strand composite. The stretched composite may be laminated between two facing sheets. Additionally, tension in the composite may be controlled through film composition, strand composition, add-on rate, stretching the composite, and combinations of any of these approaches.

Method of making strand-reinforced elastomeric composites

There is provided an absorbent system that not only takes in fluid, but then transfers that fluid further beneath the first composite. This is achieved in this invention through paired permeability, capillarity, and void volume of the first and second composites. The invention is an absorbent system composed of at least two absorbent composites that have complementary structural/surface energy characteristics. Such an absorbent system has a first absorbent Composite A which has a first permeability, a first capillarity, and a first void volume and at least one second absorbent Composite B which has a second capillarity and a second porosity multiplied by second thickness. The first absorbent Composite A is in liquid communication or contact with at least one second absorbent Composite B, such that the first absorbent Composite A, and the second absorbent Composite B have a fluid partitioning amount in Composite A, a third triple intake time (IT3) and a rewet value.

Personal care products having reduced leakage

There is provided an intake/retention/transfer material for personal care products like feminine hygiene products, which is a heterogeneous composite containing between 5 and 25 weight percent of a superabsorbent or gelling material and having a density less than 0.17 g/cc. A more particular embodiment contains less than 20 weight percent and a still more particular embodiment contains 15 weight percent or less of a superabsorbent or gelling material. Also provided are absorbent articles which contain the class of intake/transfer materials mentioned above along with additional absorbent layers such that the absorption of a menses simulant provides fluid partitioning of less than 72% of fluid in the intake/transfer/retention composite. Additionally said composite should have retention capacity values greater than 2.7 g/g.
