In-line processes for producing scrubby substrates, and related scrubby substrate cleaning articles. The process may include melting a polymer resin material, and extruding or otherwise dispensing the molten polymer resin material through one or more orifices of a heated nozzle, into a stream of hot inert gas, which attenuates the molten resin, so that the resin forms into elongated globules (rather than fibers or filaments). Such globules may have irregular cross-section and/or irregular thickness along a length of the globules. Alternatively, the molten resin may be formed into substantially continuous or discontinuous string or chain pattern of abrasive fibers, exhibiting a high frequency, low amplitude substantially linear pattern on the base substrate. In either case the globules or abrasive fibers are collected onto at least a portion of a base substrate layer to form a scrubby substrate that is more abrasive than typical meltblown materials.
