Abstract
A fibrous mineral material serving as an absorbent, especially for hygienic products such as diapers, sanitary napkins, bandages and similar products, is comprised at least partially of these mineral fibers, which have a specific surface area greater than 0.25 m.sup.2 /g. The material has an appreciably greater absorption capacity than the regularly-used cellulose fluff-based products.
