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.

Multicomponent apertured nonwoven

The present invention provides a composite nonwoven fabric with a superior combination of extensibility, tensile properties and abrasion resistance. The composite nonwoven fabric ( ) comprises at least one layer containing multipolymer fibers, with a plurality of bonds bonding the fibers together to form a coherent extensible nonwoven web ( ). This coherent extensible nonwoven web ( ) has a Taber surface abrasion value (rubber wheel) of greater than 10 cycles and an elongation at peak load in at least one of the machine direction or the cross-machine direction of at least 70%. A second extensible layer ( ) is laminated to this coherent extensible nonwoven web ( ).

Extensible composite nonwoven fabrics

The present invention provides multicomponent fibers arranged in structured domains. At least one of the polymer components is formed of a multipolymer blend. The present invention also provides nonwoven fabrics formed of the multicomponent fibers, the fabrics having a superior combination of extensibility, tensile properties and abrasion resistance. A second layer can be laminated to this coherent extensible nonwoven web.

A composite nonwoven fabric is provided for use as a one-piece topsheet and barrier fabric for disposable absorbent articles including diapers, catamenial products, and adult incontinence products. The fabric is engineered to have a strikethrough region that is normally surfactant treated for receiving insults and transporting them to an absorbent core material for storage. The strikethrough region is bounded by liquid barrier regions that are suitable for defining containment structures, including diaper leg cuff. The barrier and strikethrough regions can be designed to have excellent low rewet characteristics and to have balanced properties comparable to or better than conventional spunbonded topsheet at comparable or lower basis weights.

Multicomponent thermoplastic continuous filaments are provided, including hollow core multicomponent filaments. The filaments are at least partially splittable into smaller filaments in the absence of mechanical treatment or application of high pressure water jets. The surface energy of the components can be controlled to control separation of the multi-component filaments. Sub-denier and micro-denier filaments of low orientation can be produced from relatively high molecular weight polymers to produce nonwovens of surprising strength, barrier, and cover.
