“…Compared to wool fiber, the resulting porous structure increases the surface area of wool powder with more exposed adsorption sites. This facilitates the adsorption property of wool powder toward odor molecules . Therefore, the wool powder treated fabric showed greatly improved acetic acid adsorption capacity compared to the pristine fabric (Figure d).…”

“…Wool powder was fabricated based on a previously reported cutting–milling–spray drying technique (Figure S1, Supporting Information). , Briefly, recycled wool fabrics were cut into small pieces by a universal cutting machine (Pulverisette 19, Germany). Wool snippets and deionized water were premixed at a weight ratio of 1:10, which was then subjected to pulverization using a ball milling method (1S attritor, USA).…”

“…Recently, wool powder recycled from waste textiles was revealed to be a prospective substitute to the existing porous adsorbents due to its renewable resources, rich colors and great odor adsorption property . We reported that wool powder finished fabrics could achieve recyclable odor removal capacity, especially for ammonia and formaldehyde . However, wool powder loading onto textiles can only been attempted on a small scale via electrostatic self-assembly and PDMS treatment methods to bridge wool powder and fabrics.…”

Superfine powder obtained from waste natural polymer is a renewable resource that is capable of absorbing odor and being used as pigment for textile finishing. So far, the application of these powder materials has been limited only to only laboratory scale. How to unlock the limitations for continuous production on an industrial scale has not been revealed yet. In this study, we addressed the limitations of using wool powder as finishing agent in water-based paste for textile functionalization by using a pad−dry−cure method. This includes optimizing the formulation of wool powder suspension and producing 100 m long colored textile. Both the functionalized cotton and polyester fabrics effectively showed coloration effects with good washing colorfastness and designed color shades (K/S between 0.02−1.09) through adjustment of the wool powder concentration in the finishing paste. Furthermore, the functionalized fabrics showed almost a doubled odor removal rate toward acetic acid odor than pristine fabrics, indicating their deodorizing ability for air purification and body odor control. The odor adsorption mechanism was further verified by in situ FTIR analysis and DFT calculations. This biodegradable superfine powder from recycled waste resources could be a promising pigment for manufacturing deodorizing textiles with designable patterns on a large scale, not only contributing to the diversification of natural fiber products but also maintaining the sustainable development of the textile industry and environmental purification.

“…The application of textiles covers almost all areas of people’s production and life, and correspondingly, a large number of waste textile materials have been produced. − Generally speaking, textile waste mainly includes the leftovers that are produced during the chemical and mechanical actions in the textile process, the waste yarn and recycled silk produced in the process of textile production, and leftover materials produced in the process of clothing cutting. − There are also textile fibers and their product waste that are produced by residential life or other activities. − Textile fibers mainly include natural fibers (e.g., cotton, hemp, silk, and wool) and synthetic fibers (e.g., rayon, acetate, polyester, polyamide, and acrylic). − Among the main synthetic textile fibers, acrylic fiber in the textile fiber industry is also called “synthetic wool” because of its softness and warmth retention that make it very similar to wool. As the main substitute for wool, acrylic fiber has developed rapidly.…”

The large amount of waste chemical fiber textiles that exists has posed pressure on the sustainable development of the natural environment and of society. Therefore, it is of great importance to increase the added value of waste chemical fiber textiles and expand their applications in other fields. Herein, acrylic yarn from waste clothing is used as the raw material to construct a three-dimensional (3D) acrylic-based ceramic composite nanofiber solid electrolyte. The electrochemical properties of batteries based on this solid electrolyte are also investigated. We found that the fabricated composite electrolyte has good performance in lithium ion conduction and electrochemical stability because of its 3D acrylic-based ceramic composite fiber framework. The introduction of this composite electrolyte to a lithium symmetric battery enabled the battery to circulate stably for 2350 h at 50 °C without short-circuiting. In addition, all-solid-state batteries using a LiFePO4 cathode exhibited high reversible capacity. Lastly, a flexible lithium metal pouch battery was able to operate safely and stably under extreme conditions. This work demonstrates a strategy for upcycling waste textiles into ion-conducting polymers for energy storage applications.
