  • Patent number: 8247334
    Abstract: A moisture-vapor-permeable and water-resistant fiber involves a layer of base fabric, a moisture-vapor-permeable layer, and a water absorption layer. The moisture vapor permeable layer is obtained by coating or laminating the inner side of the fabric with a moisture-vapor-permeable resin, which prohibits the penetration of the water droplets but allows the penetration of the moisture vapor molecules. The moisture absorption layer with intricate and colorful design is composed of binding resin blended with fiber powder and/or inorganic powder, and which is dot-coated or dot-printed onto the inner side of the moisture-vapor-permeable and water-resistant layer. The fiber powder or inorganic powder is highly hydrophilic and highly absorbent in its moisture absorption ability, which, when the clothes are fabricated, can prevent the penetration of raindrops but allows the transmission of the evaporated vapor of sweat through the fabric. Moreover, it is capable of absorbing plentiful amount of sweat.

  • Publication number: 20110136400
    Abstract: The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.

  • Publication number: 20110021098
    Abstract: A method is described for manufacturing a finish formulation for the hydrophobic and/or oleophobic finishing of surfaces, comprising a dispersant incorporating dispersed, activated particles with hydrophobic and/or oleophobic surface groups and a binder, in which particles with hydrophobic and/or oleophobic surface groups are comminuted in the dispersant for activation, and the binder is added before or after activation. The obtained finish formulation clearly improves the physical properties of a transparent finish while maintaining very good hydrophobing/oleophobing. It is suitable for finishing all surfaces, in particular for finishing fibers or textiles of all kinds.

  • Patent number: 7838446
    Abstract: A wood enhancement agent treated engineered wood product. The wood enhancement agent typically includes at least one of a preservative, a water repellant, a fungicide, an insecticide, a stabilizing agent, wax, an ultra-violet light inhibitor, and combinations thereof, and may also include an antioxidant. The wood enhancement agent is incorporated into the engineered wood product during a billet making process or after forming the billet. The wood enhancement agent may be applied simultaneously with a bonding agent or at a later time, for example applied to a scrim log mat during a pre-press process or inside a steam press chamber. Alternatively, the wood enhancement agent may be applied to a warm billet after steam press, or to a reheated billet, by dipping, spraying, or flood coating the billet, or by diffusion, vacuum impregnation, pressure, or a combination thereof.

  • Publication number: 20100279081
    Abstract: A system and method for depositing a substance onto a substrate comprises continuously transporting the substrate in a transport direction while traversing a deposition arrangement across the substrate to deposit the substance in a number of swathes. During such movement the positions of the deposition arrangement and the substrate are controlled with respect to one another such that the swathes complement one another to provide substantially uniform coverage of the substrate. As a result of the defined arrangement, improved substrate speeds can be achieved since there is no need for the substrate to stop at each traverse.
