ABSORBENT ARTICLE WITH THREE-DIMENSIONAL HOT-MELT BONDED LAMINATE
20240197951 · 2024-06-20 ·

An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.

Multi-Layered Structure and Articles Formed Therefrom Having Improved Splash Resistance by Increased Interlayer Spacing

A splash resistant multi-layered structure is provided. The structure includes a specific arrangement of layers of material and a plurality of three-dimensional spacers that helps prevent penetration through the structure by a fluid that contacts an outer surface of the structure due to a state of forced separation that exists between two adjacent layers of the structure due to the presence of the plurality of three-dimensional spacers positioned between the layers. The plurality of three-dimensional spacers can be positioned on one of the adjacent layers of the structure such that a distance at least as large as the maximum height of the plurality of three-dimensional spacers separates the two layers from each other and can be present on a layer of material in a continuous or discontinuous pattern or can be present on a layer of material in a random fashion. The presence of the three-dimensional spacers can reduce the basis weight or eliminate one or more layers of the structure, which, in turn, can reduce thermal resistance, lower the pressure drop across the layers of the structure, and reduce the overall weight of the structure to enhance breathability and comfort.

10189959 · 2019-01-29 · ·

The present invention relates to a hydrophobic additive for use with fabric, fiber, and film. One aspect of the present invention comprises a master batch composition for use in preparing a non-woven fabric in order to increase the hydrophobicity of the non-woven fabric. In one embodiment, the master batch composition includes a polymer and a lipid ester. The lipid ester comprises 10 wt. % to 40 wt. % of the master batch. The fabric, when including the master batch composition, has a contact angle ranging from 100 to 125 when measured according to test method ASTM D2578.

20180256414 · 2018-09-13 ·

An activated composite web includes a nonwoven layer, and a formed film layer attached to the nonwoven layer. The formed film layer includes a plurality of first apertured protuberances having a mesh count of at least 35, and a plurality of second apertured protuberances. Each of the second apertured protuberances has a cross-sectional area larger than each of the first apertured protuberances. A plurality of first lanes are aligned in a first direction and have a first width extending in a second direction substantially perpendicular to the first direction. The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.
