  • Patent number: 11691385
    Abstract: A fibrous structure comprising first and second plies. The first ply comprises a first textured substrate comprising a first side comprising first discrete regions and a first continuous region extending between the first discrete regions, each first discrete region comprising an outer section and sidewall sections extending outwardly from the adjacent first continuous region to the outer section; a second side comprising first discrete portions corresponding to the first discrete regions and a first continuous portion corresponding to the first continuous region; and first polymer particles deposited on at least one of the first side or the second side. When the first polymer particles are deposited on the first side, the first polymer particles are substantially deposited on the outer sections of the first discrete regions and do not extend to the adjacent first continuous region.
