Some embodiments are directed to a method and a device that allows fragile fibers, such as carbon fibers, for example, to be recycled so that they can be reused in a new form.

A recycled fabric structure is provided, which includes a plurality of types of blended yarn arranged by weaving or interlacing. Wherein, each of the types of the blended yarn has a plurality of first fibers and a plurality of second fibers vertically arranged and interloped with each other. The plurality of first fibers accounts for 30% to 50% of the total weight of the blended yarn. The first fiber is a recycled fiber.

A welding process may be configured to convert a substrate comprised of short staple fibers into a welded substrate having significantly increased strength as compared to the raw substrate. When applied to a one-dimensional substrate, such as a yarn, the welding process may also reduce the diameter of the welded substrate compared to that of the raw substrate. Additionally, the welding process may be configured to impart superior color properties to the welded substrate compared to the color properties of the raw substrate, which superior color properties may be very pronounced when performing a welding process on a raw substrate comprised of colored and/or dyed recycled fibers.

Processing facilities, systems, devices, equipment, and associated methods of processing for recycling thermosetting polymers are described herein. In one example, a process includes reacting, under atmospheric pressure, a thermosetting polymer with a catalytic solution containing a solvent having sulfolane and/or a derivative thereof. The reaction converts the thermosetting polymer to polymer fragments dissolvable in the sulfolane and/or the derivative thereof of the catalytic solution. The process then includes causing the polymer fragments to precipitate as solid polymer fragments from the catalytic solution and separating the precipitated polymer fragments from the catalytic solution. As such, the thermosetting polymer can be recycled as the solid polymer fragments.

This disclosure relates to a composite textile that can be sustainable, as well as methods and systems for constructing the composite textile and recollecting and harvesting excess material (e.g., remnants). In at least some examples, a first pattern piece is cut from a first material layer, and a second pattern piece is cut from a second material layer. In addition, the first pattern piece can be separated from the first material layer, which can leave a first remnant, and the second pattern piece can be separated from the second material layer, which can leave a second remnant. Once separated, the first pattern piece can be stacked atop the second pattern piece, and the stacked pattern pieces can be entangled to form a composite pattern piece. The remnant associated with the first material layer can be separated from the remnant associated with the second material layer and reused.
