Layered absorbent structure
A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function.

Compositions and methods for manufacturing starch-based compositions
Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and auxiliary polymer form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

InactiveUS20050249901A1Improve barrier propertiesRemove moistureNanotechWrappersNanoparticleDesiccant
A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate of interest and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is then used to coat an article of interest in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may consists of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve the barrier properties of the structure. A desiccant material may also be included or added as a separate layer.

A security paper indicates exposure to a solvent by a solvent resistant color signal. A metal mordant dye first co-reactant and a mordant dye second co-reactant form an organic solvent-insoluble colored reaction product when the paper is washed with an organic solvent. The metal mordant dye first co-reactant and a mordant dye second co-reactant are chemically isolated from each other so as to prevent the coordinate covalent bond from forming until the paper is washed with an organic solvent. The chemical isolation can be effected by encapsulation or other physical separation of the co-reactants. The organic solvent-insoluble colored reaction product, once formed, remains entrapped in the web when the paper is washed with an organic solvent. The chemical isolation prevents the organic solvent-insoluble colored reaction product from forming upon the application of pressure alone to the paper.
