Compositions and methods for treating textile substrates to obtain superior liquid repellent properties are disclosed. Durable microscopic surface structures imparted to the fibrous substrate allow liquids to bead up and roll off of its surface. Mechanical abrasion or sanding techniques may be used to create the microscopic surface structures on the surface of a fibrous textile substrate, without substantially breaking fibers, followed by a chemical treatment using, for example, fluorocarbon-containing repellent compositions. Particles may be employed in combination with repellent compositions to achieve superior repellent properties. A property of the roughened surface fibers, the Roughness Factor, is used to characterize the microscopic surface structures on the treated textile surface. Treated textile substrates are disclosed which achieve superior water and oil repellency, even after multiple abrasion or laundering cycles.

A conductive composition comprising a conductive metal, a first resin component, and a second resin component (which is an isocyanate component) reactive with the first resin component. Metal oxides and lubricants are present as impurities on the metal surface. The second resin component is blocked at a first temperature and deblocked at a second temperature higher than the first temperature to produce first and second fluxes. The first flux reacts with the lubricant to at least partially remove oxides and lubricant from the metal surface. Removing or washing oxides and lubricants from the metal increases the conductivity of the composition. The process of depositing traces of the composition on the substrate and heating the composition to a second temperature causes decapping of the resinous components.
