APPARATUS AND METHOD TO PRODUCE TOPOGRAPHY AND MATERIALS HAVING TOPOGRAPHY

摘要

The present invention relates to an apparatus for the discrete and registered placement of chemistry. The apparatus having (i) at least one solenoid valve, the valve including an orifice; (ii) at least one chemistry source, the at least one chemistry source being in communication with the at least one valve, and being capable of communicating at least one chemistry to at least one solenoid valve; and (iii) a heating element; wherein the heating element is positioned proximate to at least one chemistry, and wherein the heating element allows the apparatus to process phase-change materials. A second embodiment of the present invention is directed to an ink-jet printing device for the registered placement of phase-change liquids. The present invention is also directed to a method for placing one or more chemistries in a discrete and registered fashion. The present invention also relates a material having fluid handling characteristics and generally includes a substrate having at least a first surface, and one or more chemistries, being applied to the first surface of the substrate in discrete droplets, wherein one or more droplets form discrete domains on the substrate. The chemistries applied to the substrate may penetrate the substrate to varying degrees wherein the varying degrees of chemistry penetration produce materials having various topographies. The topography or topographies may create fluid barriers, skin separation, or otherwise result in skin health benefits. A second embodiment of a material of the invention is directed to an absorbent article having one or more phase-change materials applied thereto. A third embodiment of a material of the invention is directed to a composite including a substrate and one or more chemistries, wherein the chemistries are applied to the substrate so as to produce a substrate having discretely placed and registered bond points.
