Abstract (en)
[origin: WO2017011722A1] A method (10) for cleaning fibers from a contaminated article is disclosed. The method (10) can include pulping (20) a contaminated article to separate the fibers or filaments from the contaminated article in a first solution to provide dissociated pulped fibers. The method (10) can also include washing (26) the dissociated pulped fibers by forming a suspension comprising the dissociated pulped fibers from the contaminated article and a detergent, applying a magnetic field to the suspension, and mixing the suspension to wash the dissociated pulped fibers while applying the magnetic field to the suspension thereby forming washed pulped fibers. Contaminates can be removed from the suspension while washing (26) the dissociated pulped fibers. The washed pulped fibers can be rinsed and dried to provide clean fibers.
