AI Technical Summary

Problems solved by technology

[0007] Limited differentiation from competitor products due to limited type / resolution of patterns obtained by hydroentangling
[0008] Due to the high speed of the machine, the pattern often collapses / becomes indistinct due to the tension applied to the material

Embodiment approach

[0067] In a first embodiment of the present disclosure, a nonwoven laminate absorbent article having two or more layers is disclosed. Specifically, such absorbent articles comprise: a top layer of hydrophobic cellulose-based spunlace, wherein said layer includes embossed raised regions, each region having a diameter of between about 0.1 mm and about 20 mm and a height of at least about 0.5 mm; a nonwoven carrier sheet layer, wherein the body facing portion of the carrier sheet is attached to the non-body facing portion of the top layer; and optionally one or more nonwoven carrier sheet layers, the one One or more nonwoven carrier sheet layers are attached to said non-body facing portion of said carrier sheet.

[0068] In an embodiment according to the preceding embodiment, wherein the hydrophobic cellulose-based spunlaced top layer has a diameter of about 2 mm to about 8 mm.

[0069] In an embodiment according to the preceding embodiment, wherein the hydrophobic cellulose-bas...

Abstract

The present disclosure presents a nonwoven laminate having two or more layers that have a 3D embossed hydrophobic cellulose-based fiber spunlace as a top layer. Also disclosed is the top layer havinga z-directional topography where the base of the top layer is attached to a second carrier sheet layer(s) by adhesive, pressure bonding, thermal bonding, hole punching, or similar bonding.

Description

technical field [0001] The present disclosure relates to three-dimensional (3D) nonwoven laminate absorbent articles having two or more layers including a hydrophobic cellulose-based hydroentangled top layer. Background technique [0002] Fibrous nonwoven web materials are widely used in many applications including, but not limited to, absorbent structures and wiping products, many of which are disposable. In particular, such materials are commonly used in personal care absorbent articles such as diapers, diaper pants, training pants, feminine hygiene products, adult incontinence products, bandages and wiping products such as baby and adult wipes. They are also commonly used in cleaning products such as wet and dry disposable wipes that can be treated with detergents and other compounds designed to be used by hand or in conjunction with cleaning devices such as mops. Another application is cosmetic aids, such as cleansing pads and wipes and make-up removal pads and wipes. ...
