Abstract: Process for treating a substrate, namely a fibre or a fibrous product, with a superabsorbent material, in which process there is applied to the surface of the substrate, which is not an aramid fibre, a layer of a water-in-oil emulsion which contains a superabsorbent material in its aqueous phase, so that there is applied to the substrate, calculated on its dry weight, 0.3 to 40 wt. % of the superabsorbent material, after which the liquid constituents of the emulsion are wholly or partially removed from the substrate.
Abstract: A method for abating the incidence of cluster formation of reducible iron-containing material during the direct reduction of said material is disclosed. The method generally comprises contacting the reducible iron-containing material with a cluster-abating effective amount of either a dispersion which comprises at least one particulate material which is substantially nonhardening in the presence of water and at least one fluxing agent or a dispersion which comprises an aluminum-containing clay.
