    摘要： A stretch composite having one or more elastomeric members disposed on at least one region of an extensible fibrous substrate to provide stretch properties to a targeted region of the substrate. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such stretch composites.

    摘要： An extensible apertured nonwoven web, and a method for making such an apertured nonwoven web. In one embodiment the method comprises the steps of providing an apertured nonwoven web, incrementally stretching it in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying tension is less than the web width after incremental stretching. In another embodiment the method comprises the steps of providing a nonwoven web; weakening the nonwoven web at a plurality of locations to create a plurality of weakened, melt-stabilized locations; applying a first tensioning force to the nonwoven web to cause the nonwoven web to rupture at the plurality of weakened, melt-stabilized locations creating a plurality of apertures in the nonwoven web coincident with the weakened, melt-stabilized locations, incrementally stretching the nonwoven web in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying machine direction tension is less than the web width after incremental stretching. An apparatus for producing a web of the present invention by this method is also disclosed. The extensible apertured nonwoven web produced has a plurality of apertures each having a hole size greater than 2 mm2, and a hole aspect ratio less than 6, the nonwoven web having an open area greater than 15% and being capable of at least 70% extension in the cross machine direction at a loading of 10 g/cm.

    摘要： Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The absorbent articles include a plasto-elastic material joined to or disposed on at least one of component of the absorbent article to impart sizing or shaping capabilities to the article. The plasto-elastic material has substantially plastic properties when said absorbent article is subjected to an initial strain cycle, for example, when the article is placed on a wearer, and has substantially elastic properties when subjected to a second strain cycle such as when the article is subsequently adjusted to conform to the size of the wearer. The absorbent article can be in the form of diapers, pull-on diapers, training pants, sanitary napkins, wipes, bibs, incontinence briefs or inserts.

    摘要： Variable stretch composites having one or more first elastomeric members disposed on a first region of an extensible substrate, and one or more second elastomeric members disposed on a second region of the extensible substrate which different from the first elastomeric members to provide variable properties to said regions of the composite. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The variable stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such variable stretch composites.
