    • A method of forming an elastomeric laminate having targeted elastic properties for use in personal care articles is disclosed. In particular embodiments, the method comprises providing first and second nonwoven webs; providing a core layer of elastomeric material under tension; sandwiching the core layer between the first and second nonwoven webs; bonding the core layer to at least one of the first and second nonwoven webs; providing an elastomeric film ribbon web under tension; sandwiching the elastomeric film ribbon web between the first and second nonwoven webs; and fusing the elastomeric film ribbon web to the first and second nonwoven webs. In particular embodiments, the core layer of elastomeric material is an elastomeric film web core layer. In particular embodiments, the elastomeric film ribbon web, the core layer, or both is/are bonded to the first and second nonwoven webs solely by fusing, without the use of adhesive.
    • 公开了一种形成具有用于个人护理用品的弹性特性的弹性体层压材料的方法。 在具体实施方案中,该方法包括提供第一和第二非织造纤维网; 在张力下提供弹性体材料的芯层; 将芯层夹在第一和第二非织造纤维网之间; 将所述芯层粘合到所述第一和第二非织造纤维网中的至少一个; 在张力下提供弹性薄膜带状网; 将弹性薄膜带状网夹在第一和第二非织造纤维网之间; 以及将所述弹性体薄膜带状纤维网熔合到所述第一和第二非织造纤维网。 在具体实施方案中,弹性体材料的芯层是弹性体膜芯层。 在具体实施方案中,弹性体膜带,芯层或两者仅通过熔融而不使用粘合剂而结合到第一和第二非织造纤维网上。
