Stitch bonded cleaning pad with variable height loop elements

A disposable cleaning pad of stitch-bonded construction adapted to be affixed to a mop head for manipulation across a surface to be cleaned, the cleaning pad comprising:

• a sorbent stitching substrate comprising at least one layer of fiber fleece having a mass per unit area of 100 to 400 grams per square meter disposed in sandwiched relation between substrate support layers;
• at least a first yarn feed and a second yarn feed disposed in stitched relation through a stitched portion of the stitching substrate, the first yarn feed forming a first loop collection within the stitched portion of the stitching substrate, the second yarn feed forming a second loop collection within the stitched portion of the stitching substrate, the second loop collection covering a smaller area than the first loop collection and defining a predefined pattern within the stitched portion of the stitching substrate, wherein the first yarn feed is stitched in a zigzag atlas stitch and provides a cover factor of 30% to 85% across the underlying stitching substrate, the first loop collection having an average pile height in the range of 1.5 mm to 3.5 mm and the second loop collection having an average pile height at least 50% greater than the first loop collection and wherein the loops forming the second loop collection have an average yarn density not less than two times the average yarn density of the loops forming the first loop collection.
