  • Publication number: 20180320116
    Abstract: A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.

  • Publication number: 20180038116
    Abstract: An anti-slip, liquid management cover article for a flooring surface. The article includes a film defining a working face. A microstructured surface is formed at the working face, and includes a plurality of primary ridges and capillary microchannels each having a bottom surface. Each primary ridge is an elongated body having a length. A shape of a portion of at least one of the primary ridges is non-uniform in a direction of the length. The capillary microchannels facilitate spontaneous wicking of liquid. With this construction, the non-uniform shape establishes an elevated coefficient of friction at the working face as measured in multiple directions. The cover article minimizes the risk of pedestrian slippage, even in the presence of water or other liquids.

  • Publication number: 20170045285
    Abstract: An article comprises a structure having an outer surface extending along a longitudinal axis. At least a portion of a cross section of the outer surface is convex. Fluid control channels extend along a channel longitudinal axis along at least a portion the convex surface. The channel longitudinal axis makes an angle between 0 and 90 degrees with respect to the longitudinal axis of the outer surface. The fluid control channels are configured to allow capillary movement of liquid in the channels and across the convex surface.

  • Publication number: 20170045284
    Abstract: A fluid control film is provided that includes fluid control channels extending along a channel longitudinal axis. Each of the fluid control channels has a surface and is configured to allow capillary movement of liquid in the channels. The fluid control film further includes a hydrophilic surface treatment covalently bonded to at least a portion of the surface of the fluid control channels. The fluid control film exhibits a capillary rise percent recovery of at least ten percent. Typically, the hydrophilic surface treatment includes functional groups selected from a non-zwitterionic sulfonate, a non-zwitterionic carboxylate, a zwitterionic sulfonate, a zwitterionic carboxylate, a zwitterionic phosphate, a zwitterionic phosphonic acid, and/or a zwitterionic phosphonate. A process for forming a fluid control film is also provided.

  • Publication number: 20160089858
    Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.
