  • Publication number: 20200179184
    Abstract: This disclosure includes embodiments of disposable absorbent articles and methods of making disposable absorbent articles that include closures with a web of material and hook fasteners that are unitary with the web. For example, some of the present disposable absorbent articles include diapers or briefs with closure members, such as back ears or front ears, defined at least in part by a nonwoven web with hook fasteners that are unitary with the nonwoven web. Use of such unitary hook fasteners allows simpler construction of such articles and/or softer closure members for improved fit and user comfort, and/or other benefits. Certain embodiments of the present methods can manufacture such absorbent articles with fewer manufacturing steps or processes and/or fewer raw materials, relative to those required to manufacture prior art absorbent articles with hook fastener patches that are added by application of a separate piece of material that includes the hook fasteners.

  • Patent number: 7744712
    Abstract: A method of making an elastic composite is provided. The method entails conveying a first web of material along a web plane path. The method also entails applying a first section of a first elastic strand onto the first web and generally transversely to the web plane path and applying a second section of a second elastic strand onto the first web and generally transversely to the web plane path. These applying steps are repeated while performing the conveying step, thereby arranging a plurality of first and second elastic elements on the first web, in generally parallel relation to one another. The resultant composite is suitable for incorporation into a disposable absorbent garment, textile or fabric structure, and the like.
