  • Publication number: 20220364281
    Abstract: A method of forming a hydro-patterned nonwoven web including the steps of forming a nonwoven batt comprising continuous spunmelt fibers, calender bonding the nonwoven batt to form a thermobonded precursor nonwoven web with a bond pattern that defines bond impressions and unbonded areas between the individual bond impressions, and hydraulically treating the thermobonded precursor nonwoven by a plurality of steps of water injection as the thermobonded nonwoven web passes over a screen. The bond pattern has specific features that provide advantages in terms of mechanical properties and visual appearance of the final nonwoven product.

  • Publication number: 20170136502
    Abstract: A composite structure including at least one paper web layer bonded to at least one nonwoven web layer by a hydroentanglement process. The paper web layer is made of natural fibers processed to have a specified kappa number depending on desired smoothness and hydrophilicity of the composite structure. In an exemplary embodiment, the paper web layer is made of a structured paper web, and the structure of the paper web is imparted to the nonwoven web layer by the hydroentanglement process. In an exemplary embodiment, the composite structure is a wipe product, comprised of a two or three layer structure, with at least one natural fiber layer. Higher machine speeds to produce a two-layer composite web comprised of one natural fiber web is achieved using a protective layer during the hydro-entangling process.

  • Patent number: 5576091
    Abstract: An absorbent article is described which has a moisture-impervious backing layer, a liner sheet comprising an integral sheet, and an absorbent-core layer positioned between the liner sheet and the backing layer. Raised elasticized barrier means form a pocket to receive exudates. The barrier means may include elastic bands that are attached only to the liner sheet in the crotch portion of the article, such as by an adhesive. The liner sheet is bonded to the backing sheet adjacent leg-opening portions of the article, but is not bonded to the backing sheet at regions of the liner sheet adjacent first and second edges of the elastic bands, such as from at least about 5 mm to about 20 mm adjacent the first and second edges of the elastic bands. Preferably, the liner sheet is free of adhesive for a region of about 8 mm to about 12 mm adjacent the first and second edges of the elastic bands. The absorbent article may be substantially hourglass shaped, or substantially rectangular shaped.
