Abstract: A method of making a nonwoven fiber web comprises: providing a melt-blown nonwoven fiber web comprising bonded primary fibers having an average fiber diameter of 2 to 100 microns, wherein the primary fibers comprise a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; opening at least a portion of the melt-blown nonwoven fiber web to provide loose primary fibers; combining the loose primary fibers with secondary fibers; and forming a secondary nonwoven fiber web comprising the primary fibers and secondary fibers. A fiber web preparable according to the method and a multicomponent fiber including a first phase comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units and a second phase comprising a non-biodegradable polymer.

Abstract: An article. The article includes a nonwoven matrix; and bioactive glass particles enmeshed in the nonwoven matrix; wherein the article is a conformable wound dressing. A method of making the article includes flowing molten polymer through a plurality of orifices to form filaments; attenuating the filaments into fibers; directing a stream of bioactive glass particles amidst the filaments or fibers; and collecting a nonwoven matrix and bioactive glass particles enmeshed in the nonwoven matrix.
