Crosslinked fiber material for wound treatment

A recently granted patent (Publication Number: US11998425B2) discloses a fiber material that includes a substrate of non-ionic, non-woven fibers crosslinked by an agent capable of forming hydrogen bonds. The non-ionic fibers may consist of polyvinyl alcohol (PVA), polysaccharides, or polyurethane polymers with specific functionalities. The agent containing hydrogen bond-forming groups such as hydroxyl, carboxyl, amino, or sulfhydryl groups is present in the fiber material in varying amounts, from 1% to 40% w/w, contributing to increased wet tensile strength by at least 5% compared to materials lacking this agent.

Moreover, the fiber material may also include antimicrobial agents, absorbing materials, and superabsorbent particles. The patent also covers a process for producing this fiber material, involving bringing non-ionic fiber materials into contact with the hydrogen bond-forming agent, followed by drying. The agent can be provided in a liquid form, enhancing the crosslinking process. This innovative fiber material and production process offer improved strength and performance characteristics, making it a promising development in the field of materials science and textile engineering.
