A fabric for use in arc and flame protection, and a process for producing a fire resistant fabric are provided. The fabric is comprised of at least 70 weight percent (wt%) aramid fiber; less than 40 wt% modacrylic; 8 wt% nylon; and 2 wt% anti-static. The process comprises shredding recycled fire resistant garments into fibers; creating yarn from the shredded fibers; weaving the yarn into fabric; and knitting the yarn to produce new garments. The fabric may be used to produce fire-resistant garments worn by workers in many industries such as the oil and gas.

The present invention discloses a method and corresponding system of processing waste fabrics to rejuvenated fibrous materials that will maintain their original quality in downstream production without a loss of downstream manufacturing efficiencies. The method involves (a) obtaining fabric data for each bale of incoming waste fabrics and storing the fabric data in a database; (b) obtaining target data relating to target product requirements; (c) processing the fabric data and the target data according to predetermined algorithms to generate a rejuvenation processing recipe which specifies bales information and rejuvenation processes information; (d) selecting corresponding bales of incoming waste fabrics for further rejuvenation processing; and (e) subjecting the selected bales to processes specified by the rejuvenation processing recipe.

A separation device includes a separation unit that has a first ejection unit having a first ejection port for depositing a material containing a fiber on a first surface, and a first suction unit having a first suction port for sucking from the first surface toward a second surface so that at least a part thereof overlaps the first ejection port, a second suction unit provided at a position different from the first ejection port and having a second suction port for sucking from the second surface toward the first surface, a detection unit that detects information on foreign matter contained in the material ejected from the first ejection port, an input unit that inputs a detection result of the detection unit, and a control unit that controls a separation condition in the separation unit based on the information input to the input unit.

Disclosed are methods of extracting an enzyme, comprising soaking a seed in an aqueous solution, homogenizing the seed to produce a homogenized suspension, and filtering the homogenized suspension to produce a crude extract, wherein the crude extract comprises urease and non-urease proteins.

Provided herein are methods for producing a fiber from a waste material comprising: (i) fraying a waste material to form a fiber base; (ii) carding the fiber base to form a recovered fiber; and (iii) spinning the recovered fiber. The waste material may comprise manufacturing scraps, damaged materials, selvedges, or combinations thereof. In some embodiments, the method may further comprise reducing the size of the waste material prior to fraying and/or blending the fiber base. Also described herein is a fiber produced from waste material using the disclosed methods.

In a process for recycling waste fabric comprising elastomeric material a polar solvent is flowed through the waste fabric in an extraction chamber to dissolve and remove the elastomeric material; the solvent is evaporated in an evaporation chamber and condensed to be sent to a solvent collection tank or back to the extraction chamber; the dissolved elastomeric material is eventually recovered from the concentrated polar solvent.
