  • Patent number: 6833334
    Abstract: A cover (200) for inhibiting corrosion of a metallic object over which the cover is placed. The cover has an inner surface (104) defined by a liquid-permeable layer (202) and an outer surface (102) defined by a liquid-impermeable layer (204). A moisture-absorbing layer (206) is sandwiched between the liquid-permeable layer and the liquid-impermeable layer. 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. The method includes covering a metallic object with cover (200).

  • Publication number: 20040253891
    Abstract: For a protective garment, such as a protective coat for a firefighter, a composite structure comprises an outer shell, a moisture barrier within the outer shell, a moisture absorber, which absorber may incorporate a superabsorbent polymer, within the moisture barrier, and an innermost layer within the moisture barrier, wherein the innermost layer is hydrophobic but is moisture-pervious. In one contemplated embodiment, the innermost layer is made from synthetic, hydrophobic fibers, which fibers are woven so as to be moisture-pervious and which fibers are surfactant-treated so as to promote their being moisture-pervious. In another contemplated embodiment, the innermost layer is made from a sheet of a synthetic, hydrophobic material, which sheet is apertured so as to be moisture-pervious. In another contemplated embodiment, the innermost layer is made from natural fibers, which fibers have a hydrophobic finish and which fibers are woven so as to be moisture-pervious.

  • Publication number: 20040242100
    Abstract: The leather-like sheet substrate of the present invention comprises a fiber-entangled nonwoven fabric that comprises a microfine fiber bundle (A) and a microfine fiber bundle (B) in a blending ratio (A)/(B) of 30/70 to 70/30 by mass and a polymeric elastomer contained in the fiber-entangled nonwoven fabric. The microfine fiber bundle (A) comprises 10 to 100 microfine fibers each of which has a single fiber fineness of 0.5 dtex or less and which are made of an elastic polymer having a JIS A hardness of 90 to 97. The microfine fiber bundle (B) comprises a microfine fiber which has a single fiber fineness of 0.5 dtex or less and which is made of a non-elastic polymer. Because of its excellent stretchability in both the machine and transverse directions and drapeability, the leather-like sheet substrate is particularly suitable as the material for clothing.

  • Patent number: 6823530
    Abstract: An absorbent swimwear garment having an antimicrobial agent based on hydantoin chemistry for the purpose of eliminating or reducing the level of bacteria in swim water. During initial product use, the absorbent swimwear garment is able to contain urine and bowel movements, similar to ordinary diapers and training pants. When the swimwear garment is submersed in swim water, particularly chlorinated or brominated water, the antimicrobial agent is stabilized and is thereby able to eliminate E. coli and other fecal bacteria from the swim water.

  • Publication number: 20040203308
    Abstract: A process for making an absorbent material involves flash-drying a superabsorbent polymer precursor composition. The process may be used to make a superabsorbent-fiber material without the necessity of mixing conventional superabsorbent solid particles with pulp fluff is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent material. One or more streams of superabsorbent polymer precursor composition are provided, to which a plurality of individual fibers may be added. The resulting in-situ polymerized superabsorbent-fiber material is then flash-dried and can subsequently be formed into a superabsorbent-fiber composite. The flash-drying is relatively inexpensive and requires little drying time compared to conventional drying methods.
