This study investigates the recycling of polyamide 6 (PA 6) wastes to produce nonwoven fabrics based on nanofibers (PA‐NWNF) to promote sustainable textile solid waste management and generate a novel material with exceptional properties. PA‐NWNF characteristics can be controlled by adjusting the electrospinning parameters. A comprehensive characterization will be performed using various analytical techniques, such as scanning electron microscopy (SEM), Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET), and dynamic mechanical analysis (DMA), to evaluate the unique properties as a function of the electrospinning parameters. According to the SEM results, concentrations of 21% are suitable to produce nanofiber with a well‐defined morphology, provided that the applied voltage is maintained at 20 kV and the collecting distance is above 10 cm, irrespective of the flow rate in the established protocol. XRD and FTIR analysis indicate a gradual decrease in the α‐phase and a simultaneous increase in the γ‐phase as the solution concentration increases. Moreover, low applied voltage favored β‐form crystallization over γ and α‐forms predominant at the higher voltage. DMA and BET data reveal that the elongated droplets formed at lower concentration exhibit a low storage modulus, high damping factor, highest surface area, and smallest pore diameters.

The rapid expansion of textile industries has contributed significantly to non‐biodegradable waste generation, presenting a global environmental challenge. Additionally, waste from the mining industry, such as chrysotile serpentine, contributes to this environmental issue. Therefore, this study investigates the possibility of recycling polyamide 6 waste combined with chrysotile serpentine waste to produce nanotextile fabric‐based composite (NTF‐BC). This study highlights the environmental significance of sustainable techniques in waste management specifically within the textile industry. The chrysotile serpentine waste was intensively pulverized into nanoscale particles to eliminate its hazardous fibrous nature and facilitate the electrospinning process. Comprehensive characterization was conducted using various analytical techniques including XRD, XRF, FT‐IR, SEM, BET, and DMA, to explore the properties of prepared fabrics as a function of electrospinning parameters (Ctl.Sp concentration, spinning distance, applied voltage, and flow rate.). SEM analysis indicated optimal fabrication conditions for smoother and more homogeneous NTF‐BC at Ctl.Sp concentration of 7.5%, voltage of 20 kV, spinning distance of 15 cm, and flow rate of 1 mL/h. XRD and FT‐IR analyses showed that increasing the Ctl.Sp ratio, distance, and voltage negatively affected sample crystallinity and favored the α‐form over the γ‐form. In terms of DMA characteristics, the Ctl.Sp ratio and applied voltage positively impacted the E′ values, with minimal influence from spinning distance and rate. Notably, the highest geometric properties (i.e., SBET and Vt) of the fabricated NTF‐BC were attained at the lowest Ctl.Sp ratio of 5%.
