  • Patent number: 10588792
    Abstract: An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.

  • Patent number: 10335325
    Abstract: A disposable undergarment is disclosed. The undergarment includes a chassis and an absorbent core assembly. The chassis includes a front section, a crotch section and a rear section. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in portions of the crotch section adjacent the front and rear sections. The elastic threads are broken in the areas of the core assembly. The core assembly includes a first section of a slow acting but high absorbency SAP in pockets thereof and an underlying second section of a fast acting by lower absorbency SAP in pockets thereof.

  • Patent number: 9707135
    Abstract: A disposable absorbent undergarment is disclosed. It includes an absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place. The absorbent assembly may be quilted and corrugated. The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate. Odor removal/masking and treatment features may be provided. It addition the undergarment may include a wetness indicator.
