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.
