To mitigate these impacts, two main strategies are pursued: building effective effluent treatment plants and using eco-friendly dyes and mordants. Natural dyes, derived from tree waste or easily cultivated plants, have garnered global interest in response to environmental concerns. This study investigates the use of natural dyes on cotton fabrics and examines their potential to enhance functional properties. Typically, natural dyes require metallic salts as mordants to improve dye uptake and fastness; however, some natural dyes have limited affinity for fibers like cotton. To address this, the study employs biomordants, specifically henna and harad, to improve cotton fabric dyeability. It also examines the impact of these biomordants on the antibacterial and ultraviolet (UV) protection properties of cotton fabric. The findings indicate that henna and harad-treated <i>babool</i> bark-dyed cotton fabric shows improved dyeing efficiency, UV protection, and antibacterial properties. Henna-treated fabric particularly excels, demonstrating significant reductions in bacterial growth (93.35% for <i>E. coli</i> and 88.07% for <i>S. aureus</i>) and superior UV protection (UPF of 56.89). The synergy between henna treatment and <i>babool</i> bark dyeing enhances dye absorption, resulting in darker shades with higher UPF values.

The UD preforms are made with various weight ratios of banana/SP fibers (100/0, 75/25, 50/50, 25/75, and 0/100) and then incorporated into the epoxy resin by the hand lay-up method to fabricate composites. Their mechanical properties (tensile, flexural, impact, and hardness), fracture morphologies, and water absorption are then evaluated. Numerical analysis of the mechanical properties of hybrid composites is also carried out. It is observed that with increasing SP fiber content, the mechanical properties of composites (tensile, flexural, impact, and hardness) tend to rise, and the water absorption of composites declines. The 25% banana/75% SP fiber composite exhibits the minimum water absorption of 11.29% after 120 h, with improved tensile modulus and strength of 1.79 GPa and 53.74 MPa, and flexural modulus and strength of 1.50 GPa and 130.86 MPa, respectively, and impact strength of 65.42 kJ/m<sup>2</sup>, among other hybrids, and maximum hardness (64.2 Shore D), among all UD composites. Additionally, the mechanical performance of the UD 100% SP fiber composite is found to be noteworthy. Finite element analysis shows that composites’ tensile and flexural strengths are in excellent agreement with their experimental findings. Furthermore, fracture morphologies indicate that composites fail due to fiber pullout, fiber breakage, fiber-matrix debonding, and voids.

To address this, we introduced dodecylbenzene sulfonic acid (DBSA) as a protonating agent to enhance solubility and dispersion, aiming to improve the electrochemical performance. PANI-DBSA and PANI-DBSA-CdO nanocomposites were synthesized via in-situ chemical polymerization and characterized using XRD, FTIR, and SEM techniques.
