STITCHED YARN SURFACE STRUCTURE AND METHOD OF FORMING THE SAME

摘要

A stitched yarn surface (10) structure comprises a backing (14) the entire upper surface of which is covered by a plurality of rows of face yarn underlaps (16). The face yarn underlaps may be stitched-into the backing, or held to the backing by longitudinally extending overstitches. The yarn underlaps form a yarn surface having a height dimension D. The backing (14) has a thickness dimension T that is at least twice the height dimension D and not less than two millimeters.
