摘要： 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. In certain cases, it may be desirable to position the layer between two elastic layers so that the strength-enhancing layer does not substantially contact the nonwoven facing. In this manner, the strength-enhancing layer may avoid substantial damage during the lamination process.

摘要： 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 an extrusion- coated film/nonwoven laminate through a nip to create apertures through both the film and the nonwoven. 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.

摘要： 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") thblock 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.

摘要： 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. Through selective control over the polymer content and thickness, the present inventors have discovered that the elastic and thermoplastic films may be readily joined together under light pressure, even at ambient temperature conditions. This avoids the application of a substantial amount of heat used in conventional calender bonding processes, which can otherwise damage the film, and also minimize the need for costly adhesives.
摘要翻译：提供了一种由包含弹性膜和在横向（“CD”）上具有低强度的轻质非织造面层的层压体形成的弹性复合材料。由于面层的强度低，所以希望弹性膜具有足够的厚度和重量以增强所得复合材料的强度。不幸的是，随着薄膜厚度的增加，将弹性薄膜连接到这种轻质非织造物面层的能力变得越来越困难。就此而言，本发明人已经发现，第二层压材料可以用于由热塑性薄膜和非织造面层形成的弹性复合材料中，以赋予复合材料更高的强度。第二层压体的膜和面可以由与第一层压体的膜和面相同或不同的材料形成。无论如何，层压板的位置应使弹性膜和热塑性膜处于面对面的关系。通过选择性地控制聚合物含量和厚度，本发明人已经发现，即使在环境温度条件下，弹性膜和热塑性膜也可以在轻压下容易地连接在一起。这避免了在传统的压延机粘合过程中使用大量的热量，否则这些热量可能会损坏薄膜，并且也使得对昂贵的粘合剂的需求最小化。

摘要： 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. In certain cases, it may be desirable to position the layer between two elastic layers so that the strength-enhancing layer does not substantially contact the nonwoven facing. In this manner, the strength-enhancing layer may avoid substantial damage during the lamination process.

摘要： 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. Through selective control over the polymer content and thickness, the present inventors have discovered that the elastic and thermoplastic films may be readily joined together under light pressure, even at ambient temperature conditions. This avoids the application of a substantial amount of heat used in conventional calender bonding processes, which can otherwise damage the film, and also minimize the need for costly adhesives.
