Abstract

A sheet of wiping material has a first outer surface and a second outer surface and a core region between the surfaces. The wiping material includes absorbent fibers and non-absorbent fibers. The wiping material has a stratified structure with a fiber gradient and a higher ratio of absorbent fibers to non-absorbent fibers at the outer surfaces of the wiping material than in the core region. A method of producing the wiping material is described.
