摘要:
An absorbent article has a longitudinal direction, a transverse direction, a first major surface which forms a body-facing surface of the absorbent article, and a second major surface disposed distally from the first major surface which forms a garment-facing surface of the absorbent article. The article includes an absorbent core positioned between the first major surface and the second major surface. The article also includes at least one heat-activatable expandable structure. The at least one heat-activatable expandable structure is disposed on or below the first major surface. Application of heat to the heat-activatable expandable structure causes the heat-activatable expandable barrier structure to form distinctive designs, barriers and/or channels.

A method is provided for making a high repellency material. In one embodiment the method includes the steps of providing a polymeric material having an external surface including particle-like nanotopography, etching the external surface with a high energy treatment; and depositing a fluorochemical onto the etched external surface by a plasma fluorination process.

A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a “dry liquid concentrate”, i.e., pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.
摘要:
An antimicrobial composition that involves a synergistic mixture in terms of active agents, of a primary antimicrobial agent, such as polyhexamethylene biguanide (PHMB), a secondary antimicrobial agent, and optionally an organic acid against various kinds of microbes is described. Various additional processing aids, such as alcohols and surfactants, may also be incorporated within the mixture. The composition allows one to use a significantly less concentration of individual constituent antimicrobial agents to achieve the same or a better degree of antimicrobial efficacy. The antimicrobial composition can be applied to the surface of almost any kind of substrate material, and can achieve a killing-efficacy of about 3 Log10 reduction in microbes within 30 minutes under ambient conditions.

A nonwoven fabric composite that comprises at least one extensible layer of elastomeric fine fibers treated with a wetting agent is provided. The nonwoven fabric composite can be used a barrier layer or a wrap for an absorbent materials to prevent particles form migrating out of the absorbent material.
摘要:
An elastic laminate having improved elastomeric properties is prepared by forming an elastic layer from a thermoplastic styrene block copolymer elastomer, crosslinking the elastic layer, and bonding the elastic layer to at least one nonwoven web. The elastic layer may be crosslinked before or after it is bonded to the nonwoven web. The elastic laminate combines the advantages of relatively low cost starting materials with the performance advantages typically associated with more expensive elastomers.
摘要:
The present invention relates to a composite material including a substrate with a first and a second surface, a boundary layer which is comprised of one or more compositions, and a topical application. The boundary layer is applied on the first surface of the substrate, and the topical application is applied to a surface of the boundary layer opposite of the substrate. Transfer efficiency of the topical application is enhanced as the transfer forces necessary to separate the topical application from the boundary layer are lower than the transfer forces necessary to separate the substrate from the boundary layer.

A feminine care absorbent article includes an outer cover and an absorbent structure in superposed relation to the outer cover and defining a bodyfacing surface. A lotion formulation is deposited on the bodyfacing surface in discrete locations targeted for specific regions of the wearer's body.
摘要:
A lotion alternative, namely a nonwoven fabric treated with an aqueous-based petrolatum-surfactant mixture, simultaneously imparts fluid handling and skin health benefits during product use. The petrolatum-surfactant mixture can be applied to the nonwoven fabric by a foaming process. The foaming process is compatible with existing commercial nonwoven production equipment and in-line high production rates.
摘要:
The present invention relates to a combination for surface treatment of a substrate, e.g. a nonwoven web, used in personal care product applications. The surface treatment combination not only provides adequate fluid handling properties, but also provides a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a skin health benefit agent on skin by an aqueous emulsion mediated dissolution of the agent from a substrate with subsequent transfer and deposition onto the skin. Coatings of the skin health benefit agent on the skin resist removal, thereby preventing damage to the natural skin barrier and providing a protective barrier against chemically- and biochemically-induced skin damage.
