Beschreibung
Zusammenfassung: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.
