  • Patent number: 9358759
    Abstract: Stronger elastic laminates, as well as methods of preparing the laminates, are disclosed herein. Particularly, the present disclosure is directed to multilayered elastic laminates including a thermoplastic elastomeric film layer and a plastic layer coextruded together, and further, a facing material laminated to the thermoplastic elastomeric film layer. The laminates are stretched and then relaxed. The prepared laminates have enhanced overall strength and elasticity while having a soft, cloth-like feel, and are prepared at a lower cost.

  • Publication number: 20150089755
    Abstract: A cleaning article includes a cleaning article sheet comprising a fabric substrate, wherein the fabric substrate includes pores therein, and wherein the fabric substrate has a background moisture percentage by weight, and liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at moisture percentage by weight that is 5 to 150 percentage points higher than the background moisture percentage. The nonwoven substrate can include pores formed between and/or within the fibers and can have a background moisture percentage by weight. The substrate can include a treatment to increase the dielectric constant from the dielectric constant of the substrate without the treatment. The moisture of the article can be configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article with only background moisture.

  • Patent number: 8225729
    Abstract: A planar substrate has a moisture activated shrinking filament applied thereon. When wetted, the shrinking filament shrinks and causes the planar substrate to gather and pucker. The planar substrate with the filament thereon may be compressed into a compact shape when in a dry state.

  • Publication number: 20110077527
    Abstract: A device and clinical techniques that can help healthcare workers locate and image the general outlines of blood vessels that are located either under or near to tissue or skin surfaces are described. The device involves a substrate formed from a self-cooling polymeric matrix that incorporates at least a thermo-chromic colorant, and can provide a means to distinguish between different temperature regions when applied to a heat-emitting object or body. The device can be used in certain therapeutic or healthcare-related applications.

  • Publication number: 20110039088
    Abstract: An auxetic fiber and corresponding material that not only responds to an external force, but also responds to moisture. The auxetic fiber is made in part from a moisture activated shrinking filament. Even if no external force is applied to the fiber, a pseudo tensile force is created by wetting the auxetic fiber.

  • Publication number: 20100030173
    Abstract: A sensor that is sensitive to the presence of aqueous-based fluids is described. The sensor has a wetness indicating material immobilized or printed on a substrate. The indicating material contains at least one electron-donating leuco dye and one electron deficient receptor, and exhibits a visual signal (e.g., vivid or strong color intensity) in a dry state, which fades or disappears when in contact with a water-containing liquid. An absorbent article incorporating such a sensor to communicate to a user that the article has been exposed to water-containing fluids is also described.
