    • 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 fibrous web structure may have a Consumer Preference Indication (governing allocation of melt spun filaments between core layer and scrim layers) greater than 0. Alternatively, the filaments forming the scrim layers may constitute from 1 to 13 percent of the weight of the structure. Alternatively, the scrim layers may have a combined basis weight of from 0.1 gsm to less than 3.0 gsm. A method for forming the structure, including direct formation of layers, is also disclosed.
    • 公开了一种增强的共同形成的纤维网状结构。 网状结构可以具有夹在两个稀松布层之间的共同形成的芯层。 芯层可以由纤维素纸浆纤维和熔融纺丝长丝的共混物形成。 稀松布层可以由熔纺丝形成。 一个或两个稀松布层和任选的芯层的长丝也可以是熔喷丝。 纤维幅材结构可以具有大于0的消费者偏好指示(控制在芯层和稀松布层之间的熔纺丝的分配)。或者,形成稀松布层的长丝可以占结构重量的1至13%。 或者,稀松布层可以具有0.1gsm至小于3.0gsm的组合基重。 还公开了一种用于形成结构的方法,包括直接形成层。

    • 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, and the filaments forming one or both scrim layers may have a number average diameter of 4.5 μm or less. Filaments of one or both of the scrim layers, and optionally the core layer, may also be meltblown filaments. Alternatively, the filaments forming the scrim layers may constitute from 1 to 13 percent of the weight of the structure.
