An impregnation liquid is provided, which includes (A) phenolic resin, (B) diazonaphthoquinone-based compound or a derivative thereof, (C) ionic compound, and (D) organic solvent. The weight of (A) phenolic resin and the weight of (B) diazonaphthoquinone-based compound or a derivative thereof have a ratio of 0.2:0.8 to 0.9:0.1, and the weight of (C) ionic compound and the total weight of (A) phenolic resin and (B) diazonaphthoquinone-based compound or a derivative thereof have a ratio of 0.2:1 to 1.4:1. The impregnation liquid can be used to form an activated carbon layer to wrap and to be directly in contact with the surface of a mesh.

An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.

A method for processing natural or synthetic leather by using super-critical CO.sub.2. The leather can be dried leather, low grade leathers, thin leather, crust leathers, finished leathers, wet blue leathers, and tanned leather, as well as synthetic leather. In a second aspect the invention relates to leather obtained by said method, and in a third aspect to a stand-alone apparatus for performing said method.

The present invention relates generally to methods of producing, using, and storing stable aqueously dispersed superhydrophobic compositions made from these compositions to provide superhydrophobic treatments on a range of porous, semi-porous, and non-porous target materials and surfaces as well as combinations of these materials and surfaces. More particularly, the present invention provides stably dispersed waterborne superhydrophobic compositions comprising colloidal silica or hydrophobically-modified silicon dioxide (i.e., silica) and one or more additional agents and/or compounds. When the compositions of the present invention are applied (e.g., via spray deposition, immersion, liquid application, and the like) to a suitable target material and/or surface the target is imparted with a durable (super)hydrophobic coating.
