  • Patent number: 6632504
    Abstract: A nonwoven web is provided which can be readily converted to an apertured web by stretching. In its initial non-apertured state, the web comprises a plurality of multicomponent fibers comprising at least two thermoplastic polymer components arranged in at least first and second separate continuous structured domains. The polymer component of the first domain comprises polyethylene. Prior to stretch aperturing, the web has a peak elongation of at least 100 percent and is characterized by having a plurality of discrete, spaced-apart, frangible bond sites of polymer bonding the fibers to form a coherent extensible nonwoven web. The frangible bond sites are structured and arranged to readily rupture when subjected to tensile stress to form discrete, spaced-apart apertures in the nonwoven fabric. The web has a total energy absorption in at least one of the machine direction or the cross-machine direction of at least 50 gcm/cm2.

  • Publication number: 20020193032
    Abstract: A spunbond nonwoven fabric is provided from a multiplicity of substantially continuous filaments which form a web having a length dimension and a width dimension. The filaments are arranged to define a substantially uniform web basis weight along one of dimension of the fabric, while in the other dimension, the filaments are arranged to define adjacent zones of a relatively lower web basis weight and a relatively higher web basis weight which is at least 25 weight percent greater than the basis weight of the lower basis weight zone. The spunbond nonwoven fabric can be combined with one or more additional layer to form a composite nonwoven fabric. The fabric is useful in various articles that utilize nonwovens, such as diapers, protective clothing, and hygiene articles.

  • Patent number: 5997989
    Abstract: A spunbonded elastic nonwoven fabric comprises a web of bonded thermoplastic filaments of a thermoplastic elastomer. The spunbonded fabrics of the invention are prepared in a slot draw spunbonding process operated at a rate of less than about 2000 meters per minute. The elastic fabric is used in absorbent products, such as disposable diapers, adult incontinence pads, sanitary napkins and the like, and as coverstock for absorbent personal care products.
