A respiratory mask including a mask fabric body (1), and one or more holding straps (3) for holding the mask body to the face of a user, the mask body being made of a woven fabric having weft yarns and warp yarns, the weft and warp yarns having a count comprised between 10 and 1100 den, the warp density being between 14-130 warps/cm, the weft density being between 12-70 wefts/cm, wherein at least part of the body is provided with a liquid-repellent crosslinked polymer.

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.

The present disclosure is to a fly fishing line and a method of making a fly fishing line. The method includes preparing a composition comprising a polymer resin, a co-polymer of silicone, and one or more other polymeric materials. The method includes applying the composition around an elongated core. The method also includes exposing the composition to conditions that form a coating around the elongated core thereby forming the fly-fishing line. The composition is a plastisol composition and the polymer resin is a polyvinyl chloride resin. The fly fishing lines include an elongated core a coating disposed around the elongated core. The coating comprises a polymer resin, a co-polymer of silicone, and one or more other polymeric materials.

A method for producing water repellent down includes soaking cleaned down in an aqueous solution having a pH ranging from 4 to 7; adding to the solution a cross-linking agent composed of a material having an isocyanate or acrylic acid functional group to provide a solution having a weight ratio of the down and the cross-linking agent ranging between 1:0.005 and 1:0.06; adding to the solution a water-drawing agent composed of a material having a siloxane functional group to provide a solution having a weight ratio of the down and the water-drawing agent ranging between 1:0.01 and 1:0.1; stirring the solution for at least 15 minutes to react the cross-linking agent and the water-drawing agent and form a water repellent layer on the surface of the down; separating the down from the solution; and oven drying the down with hot air having a temperature of at least 120° C.
