  • Non-planar arcuate shaped absorbent liner
    Patent number: 4023571
    Abstract: An absorbent nether garment liner is provided which comprises an absorbent layer having a first and second major surface and exhibiting an elongation under tensile stress which is recoverable and such stress is relaxed. A body fluid impervious layer overlies and is adhered to the first major surface of the absorbent layer, said body fluid impervious layer exhibiting less recoverable elongation than the absorbent layer. The absorbent layer is adhered to the impervious layer while the former is under tension and hence, elongated. Accordingly, the absorbent nether garment liner will assume a non-planar arcuate shape.
