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

Abstract: Some aspects of the present disclosure generally relates to materials such as nonwoven materials, e.g., comprising fibers. Some examples of fibers include polyester, rayon, polyethylene terephthalate, polyvinyl acetate, etc. In some embodiments, the material may be functionalized in some manner. For example, a hydrophilic polymer such as polyethylene oxide may be bonded to at least some of the fibers and/or to itself. In some cases, the hydrophilic polymer may be substantially uniformly bonded to the fibers. In some cases, the functionalized material may be relatively permeable, which may allow fluids to flow therethrough. For example, the material may have a relatively high permeability to air, e.g., of at least 5 ft3/min/ft2. Other aspects are generally directed to methods of making or using such materials, kits including such materials, etc.

Abstract: Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.

Abstract: Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.

Abstract: A method is provided for producing solid material filaments or films from a fluid of the material, by extruding the fluid by one or more extrusion openings and by solidifying the material in a precipitation bath. The formed material is guided between the extrusion openings and the precipitation bath by a lateral gas flow. The gas flow is subdivided into a hot partial flow and a cold partial flow. The material is initially brought into contact with the hot partial flow and subsequently with the cold partial flow prior to it being introduced into the precipitation bath. A device is also provided for extruding and forming materials.
