Abstract
A reusable cleaning cloth for damp and dry cleaning of surfaces. The cloth is made of a textile base layer of non-woven fibers and, on the surface that provides the cleaning action, a plurality of filament loops which project out of this surface. The filament loops are concentrated in spaced apart surface regions separate from one another, like islands, by non-linear border lines delineating channels that are essentially free of filament loops. In its finished form, the island-like areas with the filament loops project 0.5 to 5 mm out of the base surface. The islands are aligned to be equidirectionally staggered relative to one another, each having a length of 4 to 50 mm with a corresponding width of 2 to 10 mm. The channels which separate the islands are as broad as one to two of these islands in the region between the adjacent long sides of the islands and narrow in the region of the adjacent ends of the islands.
