TEXTILE RECYCLING
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. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.

PASSIVE SENSING FIBER COMPOSITIONS AND COMPOSITES THEREOF
A composition comprising: (i) an electrically non-conductive fiber having a surface; and (ii) piezoelectric particles adhered to the surface of said electrically non-conductive fiber, and optionally, (iii) a sizing agent (e.g., epoxy) coated over the piezoelectric particles and surface of the electrically non-conductive fiber. Also described are composites in which the above fiber composition is embedded within a matrix, e.g., a polymer, ceramic, or glassy carbon matrix. Also described is a method for producing a passive sensing fiber composition by: coating a fiber having a surface with a liquid suspension containing piezoelectric particles suspended in a solvent; and removing the solvent to result in the piezoelectric particles adhered to the surface of the fiber. Also described are methods for detecting formation of defects in a material and methods of generating electrical energy from ambient vibration by use of the above described fiber compositions and composites thereof.
Wound dressing for use in vacuum therapy
A wound dressing for use in vacuum wound therapy comprising a wound contact layer which is an open structure comprising a yarn comprising gel-forming filaments or fibres, the structure having a porosity which allows exudate to flow through it.

PROCESS FOR TREATING OF THREADS
The present invention provides a rapid and highly efficient process for treating textile threads, especially dyeing, and treated threads obtained thereby of textile threads.
Alcohol vapor deodorization system
A system that deodorizes gear, padding, or other apparel by killing the bacteria that cause odor. Articles to be deodorized are placed within a re-sealable airtight bag along with highly pure anhydrous ethanol. As the ethanol vaporizes, the gaseous ethanol readily dissolves within the aqueous environment that envelops the bacteria. Ethanol levels within this moisture gradually increase and eventually become bactericidal.
