Abstract

A hydrogel-forming multicomponent fiber includes: at least one first fiber component; and at least one second fiber component. The first and the second fiber components are selected independently of one another from a group consisting of polysaccharides and/or polysaccharide derivatives. The first fiber component is produced from a polysaccharide and/or a polysaccharide derivative having a water solubility of more than 50% by weight. The multicomponent fiber has a water solubility of less than 15% by weight.
