Abstract

There is provided a stretchable absorbent material for personal care products which has a liquid permeable top sheet, a bottom sheet, and beams of an absorbent composition between the top and bottom sheets whereby the beams are spaced apart by bond rows therebetween. The stretchable absorbent material provides a more conformable product and can aid in moving liquid away from the target zone, and in air circulation within the product.

  1. 1. An elastic absorbent material for personal care products comprising an elastic liquid permeable top sheet, an elastic bottom sheet, and beams of an absorbent composition between said top and bottom sheets whereby said beams are spaced apart by rows of bonds therebetween which bond together the top and bottom sheets, wherein said bonds break to accommodate the expansion of said absorbent composition upon exposure to liquids and wherein the top and bottom sheets are elastic such that when said top and bottom sheets are stretched to a length that is at least about 150 percent a relaxed, unstretched length by a biasing force, said top and bottom sheets will recover at least 50 percent elongation upon release of said biasing force.
