Embodiment

[0288] The top sheet has 0.11g / cm 3 density monocomponent high elongation spunbond polypropylene (HES PP) nonwoven. The one-component HES PP nonwoven used for the topsheet had an overall basis weight of 20 gsm. The topsheet has a width of 168mm and a length of 488mm.

[0289] The acquisition layer was a carded resin bonded nonwoven having a basis weight of 43 gsm. The acquisition layer comprised surfactant-treated 4 denier PET (polyethylene terephthalate) fibers. The fibers were bonded together using 15 gsm of resin with a glass transition temperature (Tg) of +15°C. The acquisition layer of the topsheet / acquisition layer laminate had a width of 90mm and a length of 338mm.

[0290] The topsheet and acquisition layer were attached to each other with a hot melt adhesive applied in a spiral at a basis weight of 5 gsm. The AQL is centered onto the topsheet relative to the machine direction and placed 50mm from the front MD edge of the topsheet.

[0291] The topsheet and acqui...

Abstract

An absorbent article for personal hygiene is provided and comprises a longitudinal axis, a transversal axis perpendicular to the longitudinal axis, a liquid permeable topsheet an acquisition layer, a liquid impermeable backsheet and an absorbent core. The absorbent core is located between the topsheet and backsheet. The absorbent core comprises an absorbent material. A width of the acquisition layer in a direction parallel to the transversal axis is less than a width of the topsheet in a direction parallel to the transversal axis. The absorbent article comprises a topsheet / acquisition layer laminate comprising the liquid permeable topsheet and the acquisition layer in a face to face relationship, wherein the topsheet / acquisition layer laminate comprise three-dimensional protrusions extending from a plane of the topsheet / acquisition layer laminate. The three-dimensional protrusions are oriented away from a wearer-facing surface of the absorbent article. The topsheet / acquisition layer laminate has a Measured Plane Area Factor of at least 0.5 according to the Plane Area Factor Test Method.

Description

technical field [0001] The present invention provides an absorbent article for personal hygiene, such as a baby diaper, training pants, feminine napkin or an adult incontinence product. The absorbent article comprises a topsheet / acquisition layer laminate. Background technique [0002] Absorbent articles generally comprise a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. Absorbent articles may also include an acquisition layer and, optionally, a distribution layer. The acquisition layer is capable of receiving liquid bodily exudates from the topsheet for temporary storage. The optional distribution layer can then receive liquid bodily exudates from the acquisition layer and distribute and transfer them to the absorbent core for efficient utilization of the absorbent core. Such absorbent articles exhibit satisfactory fluid handling characteristics. [0003] The skin can react sensitively to pressure exerted on it. In effect,...
