A three-dimensional interlayer composite carpet that can be washed without deformation is provided in the present invention, which includes a surface layer, a three-dimensional interlayer, and an anti-slip layer. The three-dimensional interlayer is composed of an upper knitted fabric layer, a lower knitted fabric layer, and a composite filament connecting layer arranged vertically in the middle and connecting the upper layer and the lower layer. The three-dimensional interlayer composite carpet adopting a composite filament connecting structure of the present invention has strong supporting force and high extensibility, and can be repeatedly folded for more than 1000 times. The washing shrinkage of 10 washings does not exceed 2%, and the composite carpet will not be deformed under long-term squeezing, heat, and moisture.

In example aspects, materials are repurposed for footwear manufacturing. That is, in some instances, materials in the footwear manufacturing supply chain are potentially subject to disposal. However, aspects of this disclosure sustainably repurpose those materials (that might otherwise be disposed of) to be used in footwear articles. In some aspects, the repurposed materials may be obscured with a concealing layer.

An embodiment is a method of recycling carbon fibers that includes: preparing a carbon fiber reinforced plastic formed product that includes a carbon fiber reinforced plastic containing a carbon fiber and a resin; thermally decomposing or dissolving the resin in the carbon fiber reinforced plastic formed product by a first heating process or a first dissolving process; and winding while drawing the carbon fiber from the carbon fiber reinforced plastic formed product after the first heating process or the first dissolving process. The winding further includes thermally decomposing or dissolving a residue of the resin attached to the carbon fiber by a second heating process or a second dissolving process and adding a sizing agent to the carbon fiber after the second heating process or the second dissolving process.

A shoe may include various features to improve performance, increase manufacturing efficiency, and provide environmental benefits over traditional shoes. In some cases, a shoe includes an upper portion constructed from a continuous textile that includes multiple regions having different textile properties to improve the performance of the shoe, including durability and comfort. The upper portion may define a cuff region and a flex region adapted to expand to allow a wearer to put on the shoe and to contract to retain the shoe on the wearer's foot. The shoe may further include a heel retainer adapted to conform to a shape of the wearer's foot and retain the shoe on the wearer's foot. Eyelets of the shoe may be positioned along an external surface of the upper portion to improve comfort and simplify manufacturing.

The present invention relates to a waterless fiber dyeing method using a mixed fluid medium, in which supercritical carbon dioxide fluid medium is mixed with steam to form a mixed fluid medium, so that the waterless fiber dyeing effect to natural fibers is improved. The method of the invention can effectively modify the hydrophobic supercritical carbon dioxide fluid medium and improve the polarity thereof, thereby increasing the solubility of polar dye under the dyeing condition and simultaneously expanding the fiber. Thus, the present invention significantly improves the dyeability and dyeing behavior of the hydrophilic fibers in supercritical carbon dioxide fluids. The invention has the advantages of simple process, convenient operation and low energy consumption, and avoids consuming a large amount of water resources and discharging pollutants in the traditional process, and has the characteristics of environmentally friendly and high efficiency.

A continuous wire drive system for a needleless electrospinning apparatus, the electrospinning apparatus including an electrospinning enclosure and within which a nanoscale or submicron scale polymer fiber web is formed onto a substrate from a liquid polymer layer coated onto a plurality of continuous electrode wires passing through the electrospinning enclosure. The continuous wire drive system includes a master wire drive drum and a slave wire drive drum, each of the master wire drive drum and slave wire drive drum including a plurality of wire guides, each of the wire guides including a channel or groove for receiving one of the plurality of continuous electrode wires. The continuous wire drive system is external to the electrospinning apparatus, and the continuous wire drive system drives the plurality of continuous electrode wires through the electrospinning enclosure.
