Abstract
A reinforced fiber web has first and second opposed major sides and comprises first and second fiber webs having a reinforcing mesh disposed therebetween. The first and second fiber webs are physically entangled with each other and the reinforcing mesh. A wound dressing material comprises the reinforced fiber web, a first wound-contact scrim, and a first antimicrobial layer sandwiched therebetween. The first wound-contact scrim comprises water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units.
Claims20
A wound dressing material comprising:
- a reinforced fiber web having first and second opposed major sides, wherein the reinforced fiber web comprises first and second fiber webs having a reinforcing mesh disposed between the first and second fiber webs, and wherein the first fiber web, the second fiber web, and the reinforcing mesh are bonded to one another by a combination of physical entanglement and thermal bonding;
- a first wound-contact scrim comprising first water-sensitive fibers, wherein the first water-sensitive fibers comprise a first copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units;
- and
- a first antimicrobial layer disposed between the first major side of the reinforced fiber web and the first wound-contact scrim.
A reinforced fiber web having first and second opposed major sides, wherein the reinforced fiber web comprises first and second fiber webs having a reinforcing mesh disposed therebetween, wherein the first fiber web, second fiber web, and the reinforcing mesh are bonded to one another by a combination of physical entanglement and thermal bonding, and wherein at least one of the first and second fiber webs comprises water-sensitive fibers comprising hydrophilic aliphatic thermoplastic polyurethane.
A method of forming a reinforced fiber web, the method comprising:
- providing a first fiber web;
- providing a second fiber web;
- disposing a reinforcing mesh between the first and second fiber webs;
- and
- bonding the first fiber web, the second fiber web, and the reinforcing mesh together by a combination of physical entanglement and thermal bonding to form a unitary reinforced fiber web structure having first and second opposed major sides.
