  • Absorbent article with densified areas
    Patent number: 4443512
    Abstract: An absorbent article comprising a pad of absorbent material sandwiched between a backing sheet and a top sheet. The absorbent material is a wood fluff or the like and the absorbent article is embossed on either side or both sides so that the absorbent material is compressed at the discrete areas. The balance of the absorbent material remains substantially uncompressed to form spaced densified areas and areas of less density to enhance fluid spreading characteristics and to reduce wetback.
