  • Method of making a nonwoven fiber web, nonwoven fiber web, and multi-component fiber
    Patent number: 12000071
    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.

  • COMPOSTABLE MULTI-COMPONENT CONSTRUCTIONS
    Publication number: 20230054664
    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/10 min using a 2.16 Kg weight at 190° C.

  • WOUND DRESSING MATERIAL AND METHODS OF MAKING AND USING THE SAME
    Publication number: 20220378621
    Abstract: A wound dressing material comprises first and second wound-contact scrims, and an antimicrobial layer disposed therebetween. The wound-contact scrims comprise water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units. The wound dressing material may be contacted with an exposed surface of a wound. A method of making the wound dressing material is also disclosed.

  • WOUND DRESSING MATERIAL AND METHODS OF MAKING AND USING THE SAME
    Publication number: 20220280681
    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.
