The composite fabric is heat sealable and can be fabricated utilizing hermetically seal seams, and has application in protective clothing and equipment, indoor and outdoor covers, containment systems, bags, drapes, gowns, remains pouches, etc.
Abstract: A method and means for enhancing the inner environment of a package containing perishable merchandise include taking a closable package containing perishable merchandise and placing in the package a multi-layered sheet including a plurality of layers comprised of moisture absorbing materials to absorb any residual moisture emanating from the perishable merchandise. The multi-layered sheet includes a quantity of CO2 generating material incorporated therein. The CO2 generating material is exposable to humidity and any residual moisture within the package and any moisture absorbing material to allow the CO2 generating material to emit an atmosphere of CO2 within the package from exposure to moisture within the air in the package, and to absorb any residual moisture in the package.
Abstract: Disclosed is an absorbent structure having wet integrity greater than about 4.0 mN/gsm, softness greater than 8.0/J, pliability greater than about 70/N, and providing a substantially dry liquid-accepting surface after receiving a quantity of liquid. The structure includes an upper ply having an upper fluid receiving surface and a lower surface and including (i) a top stratum including synthetic matrix fibers bonded with a binder, the matrix fibers having length from about 2 to about 15 mm; (ii) a middle stratum in fluid communication with the top stratum, the middle stratum including natural fibers, superabsorbent particles and a binder; and (iii) a bottom stratum in fluid communication with the middle stratum, the bottom stratum including natural fibers and a binder.

Abstract: The apparel is constructed from various combinations of layers of materials with moisture transfer properties. A first liner of moisture transfer fabrics abuts a second layer of structural material such as a foam. The second layer can abut a breathable membrane and/or an insulating material. Finally, carefully selected outer fabrics complete the combination to provide apparel with improved performance characteristics. The outer fabrics are treated in various ways to enhance performance.
Abstract: A thermal interface includes nanofibrils. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of larger diameter fibers. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled nanotubes.

Abstract: A fiber velvet comprising nano-size fibers or nanofibrils attached to micro-size fibers is disclosed. Methods of manufacturing the velvet as well as various uses of the velvet are also described. For example, the fiber velvet can be used as a thermal interface or as an adhesive material. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of the micro-size or larger diameter fibers. Various attributes of the micro-size fibers and of the nano-size fibers, for example, geometry (e.g. size, length, packing density) material type (e.g. carbon, metal, polymer, or ceramic) and properties (e.g. conductivity, modulus, surface energy, dielectric constant, surface roughness) can be selected depending on the desired attributes of the fiber velvet. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled carbon nanotubes.

Abstract: The thermal foot cover is an article of footwear to be worn when the wearer's foot is subjected to cold temperatures. The thermal foot cover has an upper cover portion attached to a bottom panel to define a cavity for insertion of a wearer's shoe-encased or boot-encased foot or a wearer's foot. The upper cover portion and the bottom panel are made from a material comprising an outer covering, a radiant barrier and a inner covering where the radiant barrier is sandwiched between the outer cover and the inner cover. The radiant barrier is the insulation system of the thermal foot cover, which reflects the wearer's body heat back inside the footwear and keeps the wearer's feet warm. The thermal foot cover is flexible, lightweight and readily washable due to the use of the radiant barrier as the insulation system.
