A wound dressing material comprises a base fiber web comprising 35 weight parts to 75 weight parts of polyether polyurethane; 17.5 weight parts to 50 weight parts of butanediol vinyl alcohol copolymer or a blend of linear low density polyethylene and ethoxylate; and 0 weight parts to 30 weight parts polyethylene terephthalate, and having first and second opposed major sides, a wound-contact scrim, and an antimicrobial layer comprising benzalkonium chloride. The wound-contact scrim comprises water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and di-valent dihydroxybutylene monomer units.
