  • Patent number: 11559183
    Abstract: A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet includes hydrophobic fiber layers arranged in a front surface layer and a back surface layer, and a hydrophilic fiber layer arranged in an intermediate layer. The hydrophobic fiber layers have an interlaced part with a high fiber density where the hydrophobic fiber layers are interlaced with the hydrophilic fiber layer. The interlaced part has at least one slightly interlaced part and at least one highly interlaced part which is formed in a dent shape and which is interlaced with a higher fiber density. The highly interlaced part is formed in an area ratio of 10 to 20% to an area of the front surface layer or the back surface layer. Static friction resistance of the wet sheet for cleaning is lower than kinetic friction resistance of the wet sheet for cleaning.

  • Patent number: 9505954
    Abstract: A method for solvent-less adhesive bonding is provided comprising depositing thin, functional, polymeric films on one or more substrates and bonding the substrates to each other or to other substrates. Depositing the polymeric films, including, for example, chemically reactive polymers and thermoplastics with adhesive qualities, may be accomplished using an initiated chemical vapor deposition technique compatible with a variety of monomers, including monomers with chemically functional moieties such as amine and epoxy groups. The technique allows for deposition of polymeric films on a wide variety of substrates/devices and provides an alternative for other coating/deposition methods that are incompatible with certain substrates/devices and/or do not provide adequate control over the resulting polymeric film. The provided method is advantageous in that it is applicable to fabrication of hybrid devices and is compatible with microfabrication technology, including that in clean-room settings.

  • Patent number: 8809210
    Abstract: A self-decontaminating fabric is manufactured from fibers such as Tencel having high surface energy and low surface roughness. Novel scouring methods eliminate substantially all contaminants from the fibers, and a novel coating process applies an anti-pathogen coating such as a halogen compound to the fabric so as to provide rapid deactivation of pathogens on contact. Novel charging methods activate or reactivate the coating, typically by exposure to chlorine. The coating is substantially free of gap regions where pathogens can survive. The high surface energy of the fibers allows a high coating concentration and provides close contact between attached pathogens and the coating. The low surface roughness reduces the pickup of pathogens by the fibers. Multi-layer embodiments include an outer layer configured for maximum anti-pathogen coating concentration, and an inner layer configured for a reduced coating concentration that is compatible with skin contact.

  • Patent number: 8772185
    Abstract: A reversible color-changing ink formulation, and a nonwoven wipe to which the ink formulation is securely bound, are provided. The reversible color-changing ink formulation includes about 55-98% by weight of a polymer binder, about 0.1-20% by weight of a reversible color-changing dye that reversibly changes between a first color and a second color at a pH of about 5.5 to about 8.0, and optional amounts of plasticizer, inorganic particulate filler, and color brightener. During use, the nonwoven wipe is impregnated with a sanitizer solution that contains a quaternary ammonium compound. The nonwoven wipe reversibly changes between a first color when impregnated with the sanitizer solution and a second color when the sanitizer solution is depleted during use. The change to the second color indicates the need to recharge the nonwoven wipe with the sanitizer solution, whereupon the first color returns.

  • Patent number: 8772184
    Abstract: A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color-changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.

    Abstract: A new orthopedic prayer mat proposed, whereas the new orthopedic prayer mat has a multiple layered structure. The top layer is made from microfiber which is antimicrobial, anti-molding, water-resistant, anti-dust and heat-resistant. The bottom layer is an anti-slip layer to prevent the user from physical injury in any situation while using the mat, and a soft polyurethane layer and an anti-fatigue layer or a hard polyurethane layer are arranged between the top microfiber layer and the bottom anti-slip layer in order to absorb pressure pressure and providing support, and the soft and hard polyurethane layer are combined at an angle to adjust the ratio of the weight-absorption and bearing to form the orthopedic prayer mat. Further the angle between the layers is tailored for users according to user's weight, height, body structure type and healthy conditions.

  • Publication number: 20140154940
    Abstract: A controlled release biocidal salt of a first component comprises a cation of a N?—(C1-C22) alkanoyl di-basic amino acid alkyl (C1-C22) ester cationic biocidal molecule and a second component comprising an anion of a monomeric anionic molecule having insignificant biocidal activity. The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises N?-lauroyl-L-arginine ethyl ester (“LAE”).

    Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.
