Abstract: An article (100) has a polyester film backing (110) and a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (110). Another article includes a polyester backing (110), a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (110), and a phenolic layer (140) disposed on the primer layer (120) on a surface opposite the polyester backing (110). The phenolic layer (120) can include abrasive particles (160). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing (110) and a phenolic layer (120) on the polyester backing (110).

Abstract: A reinforced fiber web has first and second opposed major sides and comprises first and second fiber webs having a reinforcing mesh disposed therebetween. The first and second fiber webs are physically entangled with each other and the reinforcing mesh. A wound dressing material comprises the reinforced fiber web, a first wound-contact scrim, and a first antimicrobial layer sandwiched therebetween. The first wound-contact scrim comprises water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units.
