Abstract
A multilayered flexible sheet for absorbing liquids comprises a nonsegmented flexible layer comprised of woven or nonwoven materials having the capacity to absorb liquids and a segmented flexible layer of woven or nonwoven materials having the capacity to absorb liquids being tacked face-to-face to the nonsegmented layer, the segments of the segmented layer being separated by substantially straight boundaries extending across one dimension of the sheet. The multilayered sheet can be easily folded along the boundaries between the segments of the segmented layer and therefore can be used unfolded as walk on mats, wipes, absorbent pads and response pads or folded as pillows or socks for absorbing liquids.
