Abstract
An absorbent fibrous structure having good stability and enhanced absorbency, flexibility and feel is provided comprising a loosely compacted cellulosic fibrous batt having a plurality of narrow, dense, compacted cellulosic fibrous lines formed by compacting the entire thickness of the batt. The fibrous areas of the batt adjacent the narrow dense lines extend over the lines, creating a fibrous region of lesser density than said batt above the lines, and a substantially fiber free region or tunnel immediately adjacent the lines.
