Zusammenfassung:A textile recovery method receives textile waste to be recovered, sorts the waste to separate cellulose-containing articles from cellulose-free articles, and resizes at least a portion of the cellulose-containing articles to produce a feedstock. The feedstock is treated in a cellulosic solvent reactor having at least one ionic liquid. The ionic liquid dissolves cellulose bonds between molecules of the raw material to produce a spinning dope. Cellulose fibers dissolved in a cellulose-containing spinning dope solution are extruded in a cellulose coagulation bath to recombine at least a portion of the cellulose fibers, and the recombined fibers are wet spun to produce continuous cellulose threads, which are commercially undifferentiated from native fiber threads. The synthetic fiber material is vacuum extracted or mechanically extracted from the cellulose-containing solution and recovered into a continuous synthetic fiber thread. The original color of the textile waste to be recovered can be retained or removed,
