Abstract

A cleaning cloth which is formed from a nonwoven fabric comprising synthetic resin fibers having a small diameter by forming many parallel rib parts arranged apart at given intervals by causing fibers to project out by needle punching. The edges of these many rib parts arranged parallel can serve as cleaning edges to efficiently clean the surface of an object to be cleaned. Since each rib part has a given width, moderate strength is ensured. Thus, the quantity of the deformation in compression of the edge parts caused by frictional force during cleaning can be reduced and the cloth can exhibit high cleaning performance.
