The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.

Elastic laminate and process for the manufacture of elastic laminate

An elastic laminate including a first nonwoven layer, a second nonwoven layer, and a plurality of elastic strands arranged in parallel with one another between said first and second nonwoven layers is disclosed, as well as a process for the production of the laminate. The elastic laminate includes elastic strands that are stretched and individually coated with an adhesive. The first and second nonwoven layers are attached to the stretched elastic strands to provide a corrugated elastic laminate when the elastic strands are relaxed. At least one of the nonwoven layers is attached to the strands at distinct adhesive bonding points in a repeating predetermined pattern in a lengthwise direction along the strands to form a predetermined corrugation pattern, and the nonwoven layers are substantially free of adhesive, except in the adhesive bonding points where the layers are attached to the elastic strands.

ELASTIC SHEET FOR ABSORBENT ARTICLE AND ABSORBENT ARTICLE
20200237577 · 2020-07-30 · ·

An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.

Printed 3D-elastic laminates

An aesthetically pleasing elastic film with three-dimensional characteristics is provided. In one embodiment, a two-dimensional ink structure is printed onto an elastic film, which is then activated, for example, by heat, which transforms the two-dimensional ink structure into a three-dimensional ink structure on one or more outer surfaces of the film. The location and amount of ink applied can be selectively controlled so that the film has the desired hand feel without sacrificing the elastic properties of the film. Further the printing and activating of the ink can be controlled to increase the tear resistance of the film or to conversely allow the film to tear or rip at desired locations on demand. In another embodiment, the elastic film can be laminated to a facing to form a laminate, where the outer surface of the film that is not in contact with the facing contains the three-dimensional ink structures.
