Abstract: The present invention is a multi-component fiber includes a core and a sheathing surrounding the core. The core includes a first aliphatic polyester or copolymer of an aliphatic polyester. The sheathing includes a second aliphatic polyester or copolymer of an aliphatic polyester or a polyamide, and a hydrophobic agent. The second aliphatic polyester or copolymer of an aliphatic polyester or a polyamide has a melt flow index of between about 0.5 and about 19.5 g/10min using a 2.16Kg weight at 190°C.

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 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: Nonwoven fibrous webs including a multiplicity of (co)polymeric fibers made of a mixture including from about 50% w/w to about 99% w/w of at least one crystalline polyolefin (co)polymer, and from about 1% w/w to about 40% w/w of at least one hydrocarbon tackifier resin. A process for making the nonwoven fibrous webs includes heating the foregoing mixture to at least a Melting Temperature of the mixture to form a molten mixture, extruding this molten mixture through at least one orifice to form at least one filament, applying a gaseous stream to attenuate the at least one filament to form a plurality of discrete, discontinuous fibers, and cooling the plurality of discrete, discontinuous fibers to a temperature below the Melting Temperature and collecting the discrete discontinuous fibers as a nonwoven fibrous web. The nonwoven fibrous webs exhibit a Heat of Fusion measured using Differential Scanning Calorimetry of greater than 50 Joules/g.
