  • Publication number: 20210077320
    Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

  • Patent number: 8784397
    Abstract: A leg wrap structure is provided in a disposable absorbent garment such as a diaper or training pants. The leg wrap structure has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally in generally parallel relation. Further, the top and base layers define a region of inelasticity. The leg wrap structure provides for the efficient formation of a reservoir and a plurality of fluid dams each capable of capturing a quantity of fluid to minimize the occurrence of fluid leaks from the absorbent article. Methods of forming such absorbent articles are disclosed.

The elastic composite has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally cross machine direction and in generally parallel relation. Further, the top and base layers define a first longitudinally extending side edge and a second longitudinally extending side edge between which, the elastic construction is disposed. The elastic composite further includes an elasticized region, wherein the elastic construction is disposed, a first non-elasticized region disposed between the first side edge and the elasticized region, and a second non-elasticized region disposed between the second side edge and the elasticized region.

  • Patent number: 8685190
    Abstract: A method is provided for making an elastic composite for incorporation into a disposable absorbent garment. An elastic element applicator is provided that is configured to move a section of a continuous strand of elastic element generally about a plane. A first web of material is conveyed in a first web moving direction such that the first web intersects the plane. Then, the applicator is operated to move the elastic element about the plane, thereby applying the section of elastic element onto the first web along a direction generally transverse to the web moving direction and such that the first web draws the continuous elastic strand from the elastic element applicator as the first web is conveyed away from the plane. The elastic element applicator may be in the form of a spin cylinder or bracket that is operated to spin the elastic element about the moving first web, thereby applying the elastic element on the first web.

  • Publication number: 20110036488
    Abstract: A method of making an elastic composite is provided. The method entails conveying a first web of material along a web plane path. The method also entails applying a first section of a first elastic strand onto the first web and generally transversely to the web plane path and applying a second section of a second elastic strand onto the first web and generally transversely to the web plane path. These applying steps are repeated while performing the conveying step, thereby arranging a plurality of first and second elastic elements on the first web, in generally parallel relation to one another. The resultant composite is suitable for incorporation into a disposable absorbent garment, textile or fabric structure, and the like.
