20080289762 | PROCESSES FOR INCREASING STRENGTH IN DEFINED AREAS OF A LAMINATED ABSORBENT PRODUCT - The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) are used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive. The adhesive compositions of the present invention are suitable for use in the preparation of laminated disposable absorbent products. | 11-27-2008 |
20080319099 | Multifunctional silicone blends - Generally silicone materials adapted to releasably adhere to human skin don't attach readily to substrates such as fibrous substrates (e.g., woven and nonwoven webs), films, plastic, etc. Disclosed are inventive blends of low-tack materials, such as a low-tack silicone material, and a high-tack silicone material, such as a high-tack, hot-melt, silicone adhesive, that both releasably adhere to skin and join to various substrates, including fibrous substrates. Furthermore, these same blends may be disposed between, and attached to, a silicone adhesive layer and a substrate. In other words, the disclosed silicone blends may be used to join a silicone adhesive layer to a substrate. | 12-25-2008 |

20120040185 | Toughened Polylactic Acid Fibers - Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning. | 02-16-2012 |
20120089067 | Article With Health-Benefit Agent Delivery System - A laminate having health-benefit agents therein is made by particle stabilization within the lamination process.

20120165770 | Absorbent article with stimulation composite - A stimulation material is partially bonded to a pressure-sensitive adhesive to form a stimulation blend. The stimulation blend, with or without pressure-sensitive adhesive, may be juxtaposed between two substrates to form a stimulation composite. When the pressure-sensitive adhesive is present within the stimulation composite, there are regions of the adhesive that do not contain a significant amount of stimulation material. By arranging regions of stimulation blend with respect to the pressure-sensitive adhesive regions, a pattern defined by the stimulation blend is formed. This pattern may deliver a stimulation effect that is at least as effective as using one-hundred percent stimulation blend within the stimulation composite, it not more effective. The stimulation composite may be cut into countless varieties of pledget shapes for use in personal-care absorbent articles. | 06-28-2012 |
