  • Fibres
    Patent number: 5980930
    Abstract: Highly absorbent alginate fibers are described which have use in the manufacture of dressings. The fibers and dressings described are highly swellable while also being soluble, rather than just being soluble. This is a considerable advantage for use in environments where high absorption coupled with biodegradability is desired, for example, in wound dressings such as dressings for ulcers or burns.
