Definitions

  • This application relates generally to the field of waterproofing, and more particularly to the field of waterproofing normally permeable apertured surfaces or materials, and even more particularly to the field of waterproofing materials using nanotechnology coatings or chemical compositions and treatments.
  • hydrophobic is used for surfaces having water contact angels greater than about 120 degrees
  • superhydrophobic is used for surfaces having water contact angles of greater than about 150 degrees.
  • the nanoparticle technology often provides oleophobic and other non-aqueous liquid barriers as well as creating a hydrophobic barrier.
  • the invention embodies a method of manufacturing an apertured waterproof mesh material comprising the steps of interweaving intersecting members to form a mesh material comprising apertures of a size such that said mesh material is not waterproof; treating said intersecting members with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said intersecting members and into each of said apertures such that the effective size of each of said apertures is reduced to a size that precludes passage of water through said apertures; or in other terms a method of manufacturing an apertured waterproof mesh material comprised of intersecting members, the method comprising the steps of treating said intersecting members with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said intersecting members; determining the extent of said hydrophobic field; interweaving intersecting members to form a mesh material having apertures wider than the width of each of said intersecting members, such that said hydrophobic field extends a sufficient distance into said apertures to preclude passage
  • the invention embodies an apertured waterproof mesh material produced by the above methods.
  • FIG. 1 is an illustration of an apertured material composed of intersecting members having been treated to produce a hydrophobic surface and showing the extended hydrophobic field sufficient to maintain liquid impermeability.
  • FIG. 2 illustrates a breeching member extending through a waterproof material.
  • the embodiments of the invention disclose a method of manufacturing an apertured mesh material composed of intersecting members defining apertures of sufficient size to be permeable to water, and treating said intersecting members before or after the step of intersecting the members with a nanoparticle hydrophobic, including superhydrophobic, composition that creates a hydrophobic field extending beyond the intersecting members and across and into the apertures, whereby the overlapping or adjacent hydrophobic fields preclude passage of water through said normally permeable apertures.
  • the term “mesh” or “mesh material” shall refer to and include a material, such as a fabric, screen or the like, composed of intersecting elongated members, such as threads, yarns, strings, wires, cables, rods or the like.
  • hydrophobic or superhydrophobic compositions and treatments suitable for this invention shall include but not be limited to the compositions and treatments disclosed in U.S Patent Publication Nos. 2013/0109261, 2012/0009396, 2010/0314575, 2012/0045954, and 2006/0029808, and also in U.S. Pat. Nos. 8,007,638, 6,103,379, 6,645,569, 6,743,467, 7,985,451, 8,187,707, 8,202,614, 7,998,554, 7,989,619, 5,042,991, 8,361,176, 8,258,206 and 6,723,378, and also in International Publication No. WO2013/058843.
  • the disclosure of these publications and patents as to the compositions and methods of application are incorporated herein by reference.
  • an apertured mesh material or surface 10 is manufactured by interweaving a plurality of intersecting members 11 , such as for example thread members combing to create a fabric.
  • the intersecting members 11 and therefore the apertured mesh material 10 as well, is treated with a nanoparticle hydrophobic composition through either a coating process or an absorption process.
  • intersecting members 11 may be treated with a nanoparticle hydrophobic composition sold under the brand name ULTRA EVER DRY.
  • the intersecting members 11 may be treated prior to the step of intersecting the members 11 to form the mesh material 10 , or the intersecting members 11 may be inter woven together first to form the apertured material 10 and then treated.
  • the treatment step does not physically block any portions of or reduce the actual size of the apertures 13 .
  • the intersecting members 11 are interwoven to produce apertures 13 of a size that are permeable to water. More preferably, the apertures 13 , which are generally square or rectangular in configuration, have width dimensions greater than the cross-sectional widths of the intersecting members 11 , i.e., greater than the diameters of generally cylindrical intersecting members 11 for example. Apertures of such size are typically provided in mesh materials 10 that are designed to permit significant flow of air through the mesh material 10 .
  • hydrophobic field 12 (taken herein to include superhydrophobic fields as well) that extends beyond the actual physical edges of each of the intersecting members 11 .
  • the extent of the extended hydrophobic field 12 must be measured and known, as it is this extent that determines the maximum permissible size for an aperture 13 .
  • the combination of the hydrophobic fields 12 associated with the portions of the intersecting members 11 defining an aperture 13 will combine, either because of overlapping or being sufficiently adjacent, to create a hydrophobic barrier either fully across the aperture 13 or sufficiently across the aperture 13 to create an effective aperture 14 sufficiently small in dimensions so as to preclude passage of water through the aperture 13 , thereby producing a mesh material that is liquid impermeable.
  • the extent of the hydrophobic field 12 will vary dependent upon the material of composition of the intersecting members 11 and the strength of the particular nanoparticle hydrophobic or superhydrophobic composition chosen.
  • the hydrophobic can be measured for a particular intersecting member 11 can be measured by treating the intersecting member 11 and then varying the size of the interwoven aperture 13 to determine the maximum allowable size for the aperture 13 to remain waterproof.
  • the method thus comprises determining the extent of the hydrophobic field 12 that extends beyond the physical edge of a particular treated intersecting member 11 to determine the allowable maximum size of the aperture 13 , such that the extended hydrophobic field 12 extending from the intersecting members 11 surrounding the aperture 13 will be sufficient to prevent surface wetting and water permeability by fully overlapping and extending across the aperture 13 or by extending sufficiently into the aperture 13 to create an effective aperture 14 of reduced area that is inherently small enough to preclude passage of water.
  • an aperture 13 may be present in a waterproof material 16 for the purpose of receiving a breeching or member 15 .
  • the material 16 which may be naturally liquid impermeable or treated as discussed or referenced above, the breeching member 15 passing through either a pre-made hole or bore, such as a shoelace, tie or string passing through a pre-cut hole or a grommet in a leather material, or a hole or bore made during construction, such as a stitching thread passing through a fabric.
  • the presence of the breeching member 15 in the aperture 13 may render the material 16 permeable to liquids, especially if the breeching member 15 is composed of a material susceptible to wicking, such as a shoelace or thread.
  • the breeching member 15 is treated with a nanoparticle hydrophobic or superhydrophobic composition that creates a hydrophobic field 12 , as shown in FIG. 2 , such that the combination of the nanoparticle hydrophobic or superhydrophobic treatment and the hydrophobic field 12 preclude passage of liquid through the aperture 13 whether by wicking or capillary effect.
  • the material 16 is also treated with the nanoparticle hydrophobic or superhydrophobic composition such that the hydrophobic fields 12 will overlap to better seal the aperture 13 .
  • nanoparticle hydrophobic or superhydrophobic treatment and composition have been used herein, it is to be understood that some of the nanoparticle hydrophobic or superhydrophobic treatments and compositions will also render the treated material impermeable to almost all liquids and oils, such that the effect is hydrophobic, liquid-phobic and oleophobic.
  • the allowable presence of apertures in the liquid impermeable material whether the apertures are present due to weaving manufacture, needling, apertures inherent in the material, apertures required for functionality of the object (e.g., a shoe), etc., enables surfaces, materials, coverings, garments or the like to be created, for example, that allow air passage through the material while maintaining impermeability.
  • Such materials can be utilized for normal or protective clothing, shoes, covers, tents, canopies, umbrellas, etc.
  • the invention also provides such materials that may be termed “self-cleaning”, in that the material is not susceptible to common liquid stains and is more easily cleaned of solid or particulate matter. Most preferably even the inherently waterproof materials are treated so as to be hydrophobic.
