    Abstract: A soft, absorbent nonwoven fibrous web, such as a wet wipe, capable of dispersing in an aqueous environment into unrecognizable pieces, made by a method comprising the steps of forming a wet-laid nonwoven web from an aqueous slurry of fibers; hydraulically needling the wet-laid nonwoven web; partially drying the hydraulically needled web; applying a binder composition to one side of the web; creping the web such that interfiber adhesion is disrupted and z-direction fiber orientation is introduced; optionally applying a binder composition to the second side of the web; recreping the web; drying and curing the web; and, converting the dried and cured web into a wet wipe, dry wipe, or other absorbent article. In the case of a wet wipe, a solution containing about 100 ppm of calcium ion is applied to the web, such as in a preserving solution. In the case of a dry wipe, the calcium ion is added after the binder is added to the web, and the final product is stored in a dry state. The combination of processes produces a web having desirable tensile strength, bulk and softness during storage and use, yet will disperse in an aqueous environment into unrecognizable pieces.

    Abstract translation: 一种柔软的吸收性非织造纤维织物，例如湿巾，能够在水性环境中分散成不可识别的片，该方法包括以下步骤：从纤维的水性浆料形成湿法成网非织造纤维网; 液压针刺湿法非织造网; 部分干燥液压针织网; 将粘合剂组合物施加到幅材的一侧; 使网状物起皱，使得纤维间粘合被破坏并引入z方向纤维取向; 任选地将粘合剂组合物施加到幅材的第二侧; 重新创建网页 干燥和固化网; 并且将干燥和固化的纤维网转变成湿的擦拭物，干擦拭物或其它吸收制品。 在湿擦拭的情况下，将含有约100ppm钙离子的溶液施加到幅材上，例如在保存溶液中。 在干擦拭的情况下，在将粘合剂加入到幅材中之后加入钙离子，并将最终产品以干燥状态储存。 该方法的组合在储存和使用期间产生具有期望的拉伸强度，本体和柔软度的纤维网，但是将在水性环境中分散成不可识别的片。

    Abstract: An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.

    Abstract: A use-dependent indicator system for detecting the exhaustion of an active chemical within an absorbent article is provided. The indicator system includes at least one dye component and a polymer mixture. The dye component(s) can be non-reactive and/or reactive dyes. The polymer mixture can contain a polymer, such as a latex adhesive, to facilitate control over the dissolution rate of the dye component(s). By controlling the dissolution rate of the dye component(s), an indicator system of the present invention can impart a change in color to signal the exhaustion of an active chemical incorporated within the absorbent article, such as an anti-microbial agent.
