  • Patent number: 9011625
    Abstract: An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing the film through a nip to bond the film to the nonwoven web material(s). Concurrent with bond formation, apertures are also formed in the elastic film. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Aperture and bond formation are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, bonding pattern, degree of film tension, bonding conditions, etc.

  • Patent number: 8679992
    Abstract: An elastic composite formed from a laminate that contains an elastic film and a lightweight nonwoven facing having a low strength in the cross-machine direction (“CD”) is provided. Due to the low strength of the facing, it is desirable that the elastic film have a sufficient thickness and weight to enhance the strength of the resulting composite. Unfortunately, the ability to join an elastic film to such a lightweight nonwoven facing becomes increasingly difficult as the thickness of the film increases. In this regard, the present inventors have discovered that a second laminate may be employed in the elastic composite that is formed from a thermoplastic film and nonwoven facing to impart increased strength to the composite. The film and facing of the second laminate may be formed from the same or different materials than the film and facing of the first laminate. Regardless, the laminates are positioned so that the elastic and thermoplastic films are in a face-to-face relationship.

  • Patent number: 8603281
    Abstract: An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction (“CD”) is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing.

  • Patent number: 8399368
    Abstract: A nonwoven web material that contains an elastic component is provided. The elastic component contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic component that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.

  • Publication number: 20120148796
    Abstract: An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided.

The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Apertures are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, element pattern, degree of film tension, temperature and pressure conditions, and so forth.

  • Patent number: 7820001
    Abstract: A latent elastic laminate material, and methods of making latent elastic laminate materials. The laminate includes a latent polymer, which itself may or may not possess latent elasticity, that is applied to at least one elastic member while the elastic member is in a stretched configuration. The elastic member, at least partially covered with the latent polymer, is attached to at least one substrate. The amount of latent polymer applied to the elastic member may provide enough force to overcome a retractive force of the elastic member when the latent polymer is at a temperature below a softening point of the latent polymer, yet the amount of latent polymer may be small enough to allow the laminate to retract into an elastic, gathered structure when the laminate is heated to a softening point of the latent polymer. The laminate may be incorporated into a variety of articles including personal care garments and cleaning cloths.

  • Patent number: 6969441
    Abstract: In the invention, a method is provided for producing a composite nonwoven fabric. A polymer is extruded into heated continuous filaments, possibly elastic, from the die head to a first chilled roller, wherein the extruder is configured to provide the continuous filaments to the chilled roller in a canted direction that is at a tangent or angle to the surface of the first chilled roller. The filaments are conveyed in a downward direction by way of chilled rollers to a nip. In a next step, the nonwoven web is sprayed with an adhesive and is laminated on the continuous filaments in the nip to form a composite nonwoven fabric. The continuous filaments move vertically downward approximately in line with the lamination process, facilitating automatic re-threading of filaments when they are broken or interrupted in their travel downward onto the chilled rolls.
