A fiber material comprising: a substrate of non-ionic, nonwoven fibers, at least one additional component, which is an agent that comprises at least one group capable of forming a hydrogen bond, wherein the non-ionic, nonwoven fibers are crosslinked by the agent; wherein the amount of agent in the fiber material, relative to the overall weight of the fiber material, is from 1% w/w to 40% w/w, wherein the substrate of non-ionic, nonwoven fibers comprises polyvinyl alcohol (PVA), and/or a polyurethane polymer with polyethylene glycol (PEG) and/or polypropylene glycol functionalities, and/or copolymers thereof.
A process for making a fiber material comprising the following steps: providing at least one non-ionic fiber material comprising polyvinyl alcohol (PVA), and/or a polyurethane polymer with polyethylene glycol (PEG) and/or polypropylene glycol functionalities, and/or copolymers thereof, which is present as a nonwoven substrate; bringing said at least one non-ionic fiber material into contact with at least one agent that comprises at least one group capable of forming a hydrogen bond, thereby crosslinking the non-ionic fiber material by the agent; wherein the agent is present in an amount from 1% w/w to 40% w/w in the made fiber material, relative to the overall weight of the fiber material.
