Abstract:
Method of recycling a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and the molded bodies are generated based on the cellulosic fibers after mechanically separating and chemically separating.
