The textile industry now produces thousands of tons of waste worldwide, and the total amount of discarded material waste increases yearly. Hygrothermal aging of cotton/E‐glass (hybrid) fiber reinforced with various proportions of graphene oxide (0%, 1%, 3%, 5%, 7%, and 9%) was performed. Epoxy and vinyl ester (50:50) have been chosen because of the Interpenetrating Polymer Networks (IPNs) concept. Laminates were subjected to 50, 60, and 70°C temperatures for 180 days. Further, Tg and the degree of cross‐linking have been determined by using differential scanning calorimetry (DSC). DSC analysis proves that a hot water bath enhances the cross‐linking of the polymer. IPN laminates were also intermittently weighed for water uptake, and their consecutive mechanical properties like tensile, flexural, and impact strength were obtained. From this work, it was observed that the addition of 5 w.t% graphene oxide in cotton/E glass fiber vinyl ester/epoxy resin hybrid IPN composites showed a tensile strength of 375.61 MPa, flexural strength of 393.54 MPa, Interlaminar shear strength (ILSS) of 49 MPa and the impact strength of 22.54 MPa. Moreover, the lowest inclusion of particulate addition exhibits better mechanical properties than (up to 5% of GO) the highest particulate loading into the matrix. SEM study was conducted on the broken specimens to know the impact of diffusion characteristics on the physical properties of the IPN composites.Highlights Natural and synthetic fibers are used as reinforcements. Waste cotton/E glass fiber vinyl epoxy composites are fabricated. Laminates were subjected to diverse temperatures for 180 days. The moisture diffusion coefficient is proportional to water temperature. Bathtub temperature affects the tensile strength of the laminate.

Waste fabrics have caused serious environmental pollution and resource waste, while recycling is still inefficient and costly. Herein, we designed an efficient and green method of recycling waste fabrics for the preparation of multifunctional photothermal protective materials. Modified carbonized fibers (MCFs) were obtained from carbonized waste fabrics and modified with dopamine and dodecylamine. Thanks to the photothermal synergy between polydopamine and the CFs, the MCF coating exhibited more than 95% light absorptivity in the visible wavelength range, which can rapidly heat up to 95.3 °C within 120 s under 1 kW/m 2 illumination. The excellent photothermal property in collaboration with superhydrophobicity endows MCF coating with obviously active de-icing and passive anti-icing properties. Moreover, the surface of the coated fabric can maintain a temperature of 20.1 °C under 0 °C with 1 kW/m 2 illumination, illustrating the personal thermal management (PTM) characteristics. Furthermore, the MCF coatings exhibited excellent mechanical and chemical durability, which significantly extended their service life. More importantly, the noteworthy breathability made the fabric suitable and comfortable to wear. This self-cleaning photothermal protective coating with PTM, active de-icing, and passive anti-icing properties greatly broadens the application of recycled waste fabrics and the utilization of sustainable solar energy.

“…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.
