  • Multiple ply tissue paper having piles with and without continuous network regions
    Patent number: 5830558
    Abstract: A multiple ply tissue paper structure is disclosed. The paper structure includes a ply comprising discrete relatively low density regions dispersed throughout a relatively high density continuous network. The paper structure also include a ply which does not include discrete relatively low density regions dispersed throughout a relatively high density continuous network.
