  • Enhanced co-formed meltblown fibrous web structure and method for manufacturing
    Patent number: 10682291
    Abstract: An enhanced, co-formed fibrous web structure is disclosed. The web structure may have a co-formed core layer sandwiched between two scrim layers. The core layer may be formed of a blend of cellulose pulp fibers and melt spun filaments. The scrim layers may be formed of melt spun filaments. Filaments of one or both of the scrim layers, and optionally the core layer, may also be meltblown filaments. The core layer may include consolidated masses of cellulose pulp fibers to, for example, enhance texture and cleaning efficacy of a wet wipe made from the structure. The material forming the consolidated masses may be selected and/or processed so as to cause the masses to have reduced visual discernibility relative the surrounding areas of the structure, when the fibrous web structure is wetted. A method for forming the structure, including formation and inclusion of the consolidated masses, is also disclosed.
