Abstract: A wound dressing material comprises a porous flexible foam core, a wound-contact scrim, and an antimicrobial layer. The wound-contact scrim comprises water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units. The antimicrobial layer is sandwiched between the porous flexible foam core and the wound-contact scrim. The wounds dressing material may be contacted with an exposed surface of a wound. A method of making the wound dressing material is also disclosed.

Abstract: A method of forming a random fiber web using pneumatic fiber feeding system is disclosed. The method includes providing a plurality of moveable apparatuses including a lickerin and a feeder, the lickerin configured to remove a plurality of fibers from a fibrous mat delivered to adjacent the lickerin by the feeder. The method also includes doffing the plurality of fibers from the lickerin at a doffing location within the system. The method also includes communicating an air supply to entrain the plurality of fibers with the air supply after the doffing. The method also includes controlling the air supply within a flow path between the lickerin and a collector. The method also includes collecting the plurality of fibers from the air supply on a collector to form the random fiber web.

Abstract: The present disclosure provides a thermally conductive article including a pad having first and second opposed major surfaces and a thickness therebetween. The thickness is formed of entangled thermally conductive fibers and at least a portion of the entangled thermally conductive fibers have at least one terminal end at the first opposed major surface, the opposed second major surface, or both. The pad is at least partially impregnated with a polymer. Another thermally conductive article is provided including a) a pad having first and second opposed major surfaces and a thickness therebetween; b) a first thermally conductive skin layer; and c) a second thermally conductive skin layer. The thickness of the pad is formed of aligned thermally conductive fibers, and at least a portion of the thermally conductive fibers have a terminal end at the first opposed major surface and the opposed second major surface. The first and second thermally conductive skin layers each include a polymeric matrix at least partially embedded in the terminal end of at least a portion of the thermally conductive fibers at the first and second major surfaces of the pad, respectively. Methods of making the thermally conductive articles are also provided.

Abstract: A pre-loaded wipe, including a plurality of fibers having a denier value of less than about 1.0, and having a cationic antimicrobial composition distributed throughout the plurality of fibers. The cationic antimicrobial composition includes a cationic antiseptic compound chosen from bispyridines, biguanides, bisbiguanides, polymeric biguanides, salts thereof, and mixtures and combinations thereof. The pre-loaded wipe has good properties for releasing the cationic antiseptic compound when wiped on a treatment site.

Abstract: A unit for use in evaporative cooling includes a first capped frame and a second open frame opposite the first frame. Posts are located between and coupled to the first and second frames. A porous hollow fiber membrane extends around the posts between and coupled to the first and second frames to form an interior volume. The first and second frames are configured for flow of water between them via the membrane. The membrane is configured to transport the water between the first and second frames and to provide for air flow from the interior volume through the membrane for evaporative cooling. The cooling unit can have a rounded square or diamond-shaped cross-sectional shape.
