Abstract (en)

The present invention relates to absorptive materials which are highly absorbent and which retain moisture, said dressings comprising cross-linked cellulosic fibers wherein the cross-linker has been blended with the fibers after electrostatically charging the fibers, the materials advantageously having at least one retentive membrane thereon, the retentive membrane being a layer of thermoplastic which has been laminated onto the dressing at its glass transition temperature, thereby giving the membrane selective moisture permeability properties.
