  • Publication number: 20230374712
    Abstract: A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread.

  • Patent number: 10317415
    Abstract: The disclosure relates to the identification of salivary biomarkers for diagnosis and monitoring of type 2 diabetes in a subject. Also provided are methods for noninvasively diagnosing and monitoring type 2 diabetes in a subject. More particularly, the expression of salivary biomarkers, including MUC-1, MUC-2, MUC-4, and MUC-5B, are highly associated with A1C level in African American patients with type 2 diabetes.
