  • Patent number: 7345004
    Abstract: An absorbent structure can include a matrix of fibers, wherein the matrix is reinforced with a reinforcing member, such as scrim. The scrim is secured to the fibrous matrix by entanglement of fibers with the scrim and entanglement of fibers in the matrix from opposite sides of the scrim with each other. The scrim layer can be restricted to a longitudinally extending, medial region of the absorbent. In a particular arrangement, the scrim has a cross-directional width dimension which is less than a narrowest width dimension of the fibrous matrix. The scrim can be located between two, opposed, major surfaces of the fibrous matrix. The scrim has a reduced stiffness in the cross direction which promotes fit and comfort of the absorbent structure as incorporated into a disposable absorbent garment.

The scrim layer in some embodiments is employed to make the composite finger tearable. The melt blown adhesive layer, nonwoven web layer and elastic layer form a breathable, porous elastic composite. Methods of manufacturing the composite are also disclosed.

  • Publication number: 20030003826
    Abstract: A spunbond nonwoven fabric is provided which is formed from continuous multiple component filaments which include a polyester component and a polyethylene component. The polyethylene component is a blend of high density polyethylene and a first linear low density polyethylene. The spunbond filaments are preferably formed in a sheath-core configuration with the polyester component in the core and the polyethylene component in the sheath. Composite sheets are provided which include the multiple component spunbond layer and a meltblown layer, wherein the meltblown fibers include a second linear low density polyethylene. The linear low density polyethylenes are preferably formed by polymerization of ethylene with an alpha-olefin co-monomer, where the same co-monomer is used in each of the first and second linear low density polyethylenes.

  • Patent number: 6475932
    Abstract: The fabrication of multi-layered laminated structures involves a high strength through-bonding technique. In its preferred embodiment, the structure is a nonwoven trilaminate structure which has outer layers of nonwoven material, and an inner elastomeric layer which has a plurality of openings therethrough, (e.g., an elastomeric mesh). During fabrication, beads of through-bonding adhesive (e.g., oil resistant, polybutylene-based hot melt adhesive) is applied to at least one of the nonwoven webs. The inner elastomeric mesh web and the two outer nonwoven webs are then aligned and fed into a compression nip. The compression nip compresses the webs together to obtain intimate contact of the two outer nonwoven webs through the openings in the inner elastomeric mesh web.
