Abstract

A cleaning cloth is described made of a microfilament nonwoven weighing from 30 g/m2 to 500 g/m2, the nonwoven being made from melt-spun, stretched continuous multicomponent filaments having a titer of 1.5 to 5 dtex, which are immediately laid down to form a nonwoven, and the continuous multicomponent filaments, optionally after pre-bonding, being split at least to 80% to form continuous micro-filaments having a titer of 0.05 to 1.0 dtex and bonded.
