The separator is a laminate that contains a nonwoven nanoweb and a porous layer composed of a plurality of thermoplastic particles having particle size smaller than the mean flow pore size of the nanoweb. The shutdown layer melts and starts to flow at a desired temperature, and restricts the ion flow path, resulting in a substantial decrease in ionic conductivity of the separator at the desired shutdown temperature, while leaving the separator intact.

The liquid-permeable layer allows vapor and liquid moisture beneath the cover to be absorbed into the moisture-absorbing layer to reduce the amount of moisture beneath the cover. The liquid-impermeable layer repels environmental liquid moisture, such as rain, sea spray, dew and the like and prevents such moisture from penetrating the cover. A radar-influencing layer (308) and vapor corrosion inhibitors (214) may be included in the cover. A method of protecting an object is also disclosed.

  • Publication number: 20030118779
    Abstract: A laminate structure (e.g., hot or cold wrap) formed from outer substrates that are bonded together to form at least one pocket is provided. The pocket is separated by an inner substrate such that the pocket defines an upper pocket region and a lower pocket region, each of which contains a reactant. Due to the presence of the inner substrate, the reactants do not intermix prior to activation of the laminate structure. To activate the laminate structure, a tension force is exerted so that the inner substrate ruptures, thereby allowing the reactants to freely intermix and produce the desired result. For example, in some instances, the reactants undergo and exothermic or endothermic reaction so that the laminate structure may be utilized as a hot or cold wrap.

  • Patent number: 6492286
    Abstract: Multilayer meltblown fibrous webs, as well as apparatus and methods of forming the webs. The webs are produced on a rotating collector that also moves parallel to its longitudinal axis. The webs are thus formed in a helical process, and the resulting tubular web is separated in a direction parallel to a helix angle. By separating the tubular web in a direction parallel to the helix angle, a flat multilayer meltblown fibrous web is provided that allows for incorporation of feathered edges formed during the article's manufacture.

  • Patent number: 6479415
    Abstract: Disclosed is an absorbent structure including a liquid acquisition layer and a fibrous liquid storage layer in liquid communication with the acquisition layer. The storage layer includes SAP particles. The acquisition layer includes synthetic fibers and the fibers are latex bonded. A fluid acquisition and/or distribution layer (ADL) containing at least two layers, a top layer of latex bonded synthetic fibers and a bottom layer of latex and/or thermal bonded cellulose fibers and method for preparation thereof are disclosed. The synthetic fiber layer is highly porous and provides rapid fluid acquisition under load. The cellulose layer provides z-direction capillary force to pull fluid into the absorbent product, to provide temporary fluid immobilization, and to act as a conduit for fluid to be pulled into unsaturated portion of the permanent fluid storage layer. The ADL of the invention provides increased protection against leakage relative to single-layer ADLS.
