Abstract: A wound dressing material comprises first and second wound-contact scrims, and an antimicrobial layer disposed therebetween. The wound-contact scrims comprise water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units. The wound 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 wound dressing material comprises a base fiber web, 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 base fiber web 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 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: The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Abstract: A powder-rubbing apparatus comprises: a rotatable rubbing roll having a rotational axis; a substrate path; an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis; and a powder coating die comprising an inlet port in fluid communication with an outlet port disposed adjacent to the substrate path. The substrate frictionally contacts the rotatable rubbing roll within a rubbing zone. A dispenser for dispensing gas-borne powder is in fluid communication with the inlet port of the powder coating die. The dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone. A method of using the powder-rubbing apparatus and a powder-rubbed web preparable thereby are also disclosed.
