Abstract: Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3?. Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.

Abstract: A filter media having lignite-derived activated carbon, polyacrylic acid (PAA), a commercially available copper-zinc alloy, and polydiallyldimethylammonium chloride (PolyDADMAC) or Luviquat®, which is Poly[(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)], combined and used as suitable replacement for TOG bituminous coal-based activated carbon, silver, and PolyDADMAC. Functional groups in lignite-based activated carbon interact with the polyacrylic acid. Functional groups such as calcium, iron, or aluminum oxide/hydroxide of lignite-based activated carbon interact with PAA, and help hold the PolyDADMAC in place. The additional presence of a copper-zinc alloy enhances the filter anti-microbiological performance.
