Abstract:
1. A cleaning sheet comprising a composite of a protrusion containing backing element embedded within a fibrous substrate, the composite having a first face and a second face and the protrusion containing backing element having a first face and a second face with protrusions extending from at least one face of the backing element such that these protrusion extend out so as to form at least in part a first face of the composite, wherein the protrusion containing backing element is embedded within the fibrous substrate such that individual fibers forming the fibrous substrate are present on both faces of the backing element so that the individual fibers forming the fibrous substrate form at least in part the first and second face of the composite, the protrusion containing backing element is formed of substantially continuous first and second sets of intersecting strand elements extending in at least two directions where at least one set of strand elements have integral extrusion formed protrusions extending from at least one face of the strands, the two sets of strands being separated from one another and where individual fibers forming the fibrous substrate are located between the strands.
