  • Patent number: 10704191
    Abstract: A process of fabricating the composition coating may include selecting a textile material substrate, utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate, and optionally coating the substrate with a hydrophobic chemical agent and/or other chemical agents to create a surface with nanoscopic or microscopic features. The process may utilize an all solution process or controlled environment for fabricating a composition coating that prevent wetting or staining of a substrate. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials. The composition coatings and their use for treating textile materials can also impart water repellency, oil repellency, ease of cleaning stains and removing particulates. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.

  • Publication number: 20140155535
    Abstract: A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The free polymer dispersant in the pigment dispersion is limited to less than 0.12 grams per gram of pigment. This dispersed pigment is then encapsulated by adding acrylate monomers and optionally acrylic and vinyl monomers and polymerizing. In the encapsulated pigment dispersion the weight ratio of final free polymer to polymer found to the final encapsulated pigment is less than 0.9. The free polymer dispersant is measured by a centrifugation method and the final free polymer is measured by a density gradient centrifugation method. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging test conditions, and solvent challenges. Prints from these inks have better durability.
