A cleaning cloth is described which is made from microfibers having a nonporous fiber core surrounded by a foamed coating layer containing open celled pores. The microfibers may optionally be combined with other types of fibers. The cloth has a high capacity for holding dirt and in another application, a detergent, bacteriocide, fungicide or preservative can be contained in the pores to provide a combination cleaning cloth.

A cleaning cloth, which comprises: a fabric of intermingled fibers, said fibers being bonded to each other at a substantial number of interfiber junctions and at least some of said fibers being porous microfibers of a polymeric composition, each microfiber comprising a core of substantially nonporous polymer and a foamed polymer cover layer which surrounds said core, has a sheath-like configuration around said core, is coaxial with said core and contains open micropores, said micropores having a predominantly cylindrical shape, being substantially uniformly distributed within the sheath-like cover layer, encompassing from about 40 to 80% of the cross sectional area of each microfiber and the long axes of the pores being disposed parallel to the microfiber cross-sectional radius.
