Abstract

A molding, particularly a fiber or foil molding, of cellulose regenerated an amino-oxide process provides that the cellulose contains 0.02 to 30% mass of a polyalkylene imine derivative. In addition to improved stabilization of the molding compound, the molding or fiber exhibits improved properties, such as an anion exchange capacity, fungistatic properties and an improved hydroblast resistance.
