A process of fabricating the waterproof coating may include selecting a 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 self-cleaning and waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment.

An antibacterial textile and a preparation method thereof are provided. The antibacterial textile provides advantages as followings: various sources for raw material ingredients; low cost and good antibacterial effect; safe and eco-friendly; simple in preparation method; and easy operation. Therefore, the present invention is widely applicable in industrial production.

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.

Systems, methods, and compositions for producing liquid repellant materials include a first support configured to support a spool of flexible substrate, a second support configured to support a plurality of compressing rollers configured to apply a force to a segment of the flexible substrate that extends from the roll. The segment is located within a zone between the compressing rollers. The system, in an embodiment, has a plurality of gas directors, wherein each one of the gas directors is configured to direct a stream of gas that flows at least partially around one of the compressing rollers. The streams cause an air pressure reduction in the zone. Also, the system has a precursor supply configured to expose the substrate to a precursor (e.g., a siloxane precursor), resulting in a coated material or protected material.
