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.

Method of recycling a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein the method comprises:
- comminuting the textile material;
- separating at least a part of non-fiber-constituents of the comminuted textile material from fiber-constituents of the comminuted textile material;
- mechanically separating at least a part of non-cellulosic fibers of the fiber-constituents from cellulosic fibers of the fiber-constituents, and subsequently
- chemically separating at least a further part of the non-cellulosic fibers from the cellulosic fibers;
- generating the molded bodies based on the cellulosic fibers after the mechanically separating and the chemically separating.

- generating the molded bodies based on the cellulosic fibers after the mechanically separating and the chemically separating;
- wherein after separating at least a part of the non-fiber-constituents, further comprises:
- further comminuting the separated non-fiber-constituents;
- recovering fiber residues from the further comminuted non-fiber-constituents;
- and
- supplying the recovered fiber residues to the fiber-constituents and/or to mechanically separating.
