1. A fiber material comprising:
a substrate of non-ionic, non-woven fibers, and
at least one additional component, which is an agent that comprises at least one group capable of forming a hydrogen bond,
wherein a combination of the substrate and the agent causes the fiber material to have an increased wet tensile strength of at least 5%, as measured in accordance with EN 29073-3:1992, as compared to an otherwise identical fiber material without the agent.
