HYDROGELERENDE FIBERMATERIALE

One-, two-, or three-dimensional hydro-gelled fibers or fiber structure produced from fibers of a first fiber raw material including a water-soluble polyvinyl alcohol and/or polyvinyl alcohol copolymer, is claimed. The hydro-gelling of the fiber or the fiber structure includes tempering the fiber ra...

Beschreibung
Zusammenfassung:	One-, two-, or three-dimensional hydro-gelled fibers or fiber structure produced from fibers of a first fiber raw material including a water-soluble polyvinyl alcohol and/or polyvinyl alcohol copolymer, is claimed. The hydro-gelling of the fiber or the fiber structure includes tempering the fiber raw material at a predetermined tempering temperature that is greater than a glass transition temperature and/or is less than a melting temperature or decomposition temperature of the used first fiber raw material for a predetermined tempering duration and crosslinking the fiber raw material. Independent claims are also included for: (1) preparing the hydro-gelled fibers or fiber structures, comprising tempering the above mentioned fibers or fiber structures at a predetermined tempering temperature, which is greater than a glass transition temperature and/or is less than a melting temperature of the used first fiber raw material for a predetermined tempering duration such that the fibers are crosslinked; and (2) wound dressings or wound coverings comprising the above mentioned fibers or fiber structures produced by the above mentioned method.
