1. A cleaning wipe of multi-layer, stitch-bonded construction, the cleaning wipe comprising:
at least one inner layer of cellulose tissue of insufficient coherency to support stitch-bonding and having a mass per unit area of 2 grams per square meter to 50 grams per square meter, the inner layer disposed in sandwiched relation between a first discontinuous cover layer of spunbonded polypropylene fleece and a second discontinuous cover layer of spunbonded polypropylene fleece such that the inner layer, the first discontinuous cover layer and the second discontinuous cover layer form a stacked composite and wherein the first and second discontinuous cover layers are disposed in discontinuous covering relation across opposing surfaces of the inner layer such that at least 10 percent of each opposing surface of the inner layer is not covered by an opposing discontinuous cover layer; and
a plurality of stitching yarns extending in stitched relation through the stacked composite.
