  • Publication number: 20080045917
    Abstract: A stretchable outer cover for use with an absorbent article including an elastomeric film. The elastomeric film includes at least one skin layer that is less tacky than at least one core layer. The outer cover can include a nonwoven layer different structural combinations of spunbond fibers, meltblown fibers, and/or nanofibers. The combination of plastic and elastic components results in an outer cover that has favorable mechanical, physical, and aesthetic properties. The outer cover can be rendered either uniaxially or biaxially stretchable via a mechanical activation process.

  • Publication number: 20070202767
    Abstract: A method for producing a stretch laminate includes forming an intermediate stretch laminate. Forming the intermediate stretch laminate includes providing a first substrate and attaching an elastic film to a surface of the first substrate via an adhesive. The first substrate and the elastic film are in a face to face orientation. The intermediate stretch laminate has a residual energy of greater than or equal to 50% at a predetermined applied strain. The method of forming the stretch laminate further includes mechanically activating the intermediate stretch laminate at a strain rate of at least 100 s?1.

  • Publication number: 20070203301
    Abstract: Polymeric blends and polymeric mixtures that incorporate a blend of a first polyethylene and a second polyethylene are described. The first and second polyethylenes have a predetermined relationship for the density and the melt index of the individual polyethylenes. Also described are fibers (including bicomponent fibers) and nonwoven materials made from the fibers where the fibers are extruded using the polymeric blends, and/or the polymeric mixtures.

  • Publication number: 20050215963
    Abstract: 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.

  • Publication number: 20050215964
    Abstract: An extruded web is disclosed. The extruded web can be either a nonwoven material of a films. The web comprises a plasto-elastic material where the plasto-elastic material is a combination of a first polyolefin and a second polyolefin (either a polymeric blends or a polymeric mixture). The claimed combination of polyolefins results in a material that has substantially plastic properties when a sample taken from said web is subjected to an initial strain cycle (such that the web is provided with a set of at least 30% by an initial strain cycle) and substantially elastic properties when a sample taken from the web is subjected to at least a second strain cycle.

  • Publication number: 20050165173
    Abstract: Fibers and nonwoven materials comprising polymeric blends and polymeric mixtures that incorporate a blend of a first metallocene polypropylene and a second polypropylene are described. The first and second polypropylenes have a predetermined relationship for the melt temperature and the melt flow rate of the individual polypropylenes. Also described are fibers (including bicomponent fibers) and nonwoven materials made from the fibers where the fibers are extruded using the polymeric blends, and/or the polymeric mixtures.

  • Publication number: 20010000258
    Abstract: A molded or extruded article made from a propylene, &agr;-olefin copolymer, where the &agr;-olefin has 5 or more carbon atoms (higher alpha-olefins (HAO)), where the copolymer is made with a metallocene catalyst system, provides substantially higher cold flow resistance and resiliency than when the propylene copolymer contains an &agr;-olefin of 4 or less carbon atoms. Other properties such as ultimate tensile strength and impact strength are substantially higher as well. Such polymers can be used to advantage in extruded profiles and molded parts either alone or in a thermoplastic olefin (TPO). Parts made from the propylene HAO copolymers or compounds made from them show improved creep resistance than propylene ethylene copolymers.
