A process of fabricating the waterproof 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 fluorine-free waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials while the compositions contain no fluorine-based chemicals. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.

Aspects herein are directed to using a space-treating process to apply functional finishes to a yarn and incorporating the treated yarn into a textile and/or a garment to impart engineered functional properties to the textile and/or garment.

Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying, laminating a decorative fabric to the resulting dry foamed opacifying layer, and densifying that layer to have a thickness that is at least 20% less than before densifying. This operation can be carried out so that non-woven fabric, decorative fabric, and aqueous foamed opacifying composition are supplied in a single-pass, in-line operation to make any desired quantity of a laminated light-blocking decorative article. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm.sup.3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) at least 0.0001 weight % of an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

The present invention is directed to a substrate, in particular textile material to which one or more antimicrobial and/or hydrophilic and/or stain release agents are adhered. The agent(s) is/are adhered to the substrate in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. Washability and/or usability of the textile are improved where one or more hydrophilic and/or stain release agents are adhered to the textile. The substrate can be used, e.g., in a reusable sanitary napkin or other hygiene product. The structure of the hygiene product is disclosed, together with a process of attaching the different layers of the hygiene product together by ultrasonic welding. The invention further relates to a method of finishing a substrate by applying and binding antimicrobial and/or hydrophilic and/or stain release agents to the substrate so that the agents are essentially irreversibly adhered to the finished substrate.

Provided is a method for manufacturing a water-repellent knitted fabric and a water-repellent knitted fabric. The method includes: dyeing a yarn; obtaining a knitted fabric by knitting the dyed yarn which is dyed in the dyeing of the yarn; dipping the knitted fabric in a water-repellent liquid to allow the water-repellent liquid to penetrate into a structure of the dyed yarn and to be coated on a surface of the dyed yarn; dehydrating the knitted fabric after the dipping of the knitted fabric and then incompletely drying the knitted fabric while moisture remains in the dyed yarn; adhering the water-repellent liquid applied to the knitted fabric by applying heat to the knitted fabric after the dehydrating of the knitted fabric; washing the knitted fabric using water after the adhering of the water-repellent liquid; and drying the knitted fabric after the washing of the knitted fabric.
