Nevertheless, the scale structure of wool fibers often results in felting shrinkage during processing and practical use. To address this, we propose a laccase/dopamine coupling treatment approach for wool fibers. Laccase, an eco-friendly enzyme, effectively removes scales from wool fibers. Concurrently, dopamine, a biomimetic material, is oxidized by laccase to form a polydopamine (PDA) coating on the wool fibers, thereby mitigating damage caused by scale removal. <strong>Through orthogonal optimization, key parameters were established: laccase concentration (1800 U/L), dopamine concentration (6 g/L), and treatment time (150 min). This optimized process significantly enhanced performance: breaking strength increased by 8.91 % (from 19.42 cN to 21.15 cN), and felting ball volume expanded by 19.62 % (from 14.73 cm<sup>3</sup> to 17.62 cm<sup>3</sup>).</strong> The instrument analysis results demonstrate that laccase efficiently removes wool scales and collaborates with dopamine to establish a PDA coating, thereby augmenting the mechanical properties of the fibers.

In addition, aspects concerning the scalability, reproducibility, and commercial viability of the treatment process were discussed in detail.

Additionally, it incorporates computational fluid dynamics (CFD) simulation to evaluate heat transfer behavior—an approach not commonly employed in similar material systems. This study addresses these limitations by developing a High-Volume Fly Ash Rubberized Concrete (HVFA-RC) incorporating 50 % fly ash as partial cement replacement, crumb rubber (0–30 %) as fine aggregate substitute, and 2 % nano silica by weight of binder to improve early-age strength and microstructure. Five mix designs were tested for mechanical, durability, and thermal properties, and further analyzed using CFD-based simulations in ANSYS CFX. Results revealed that increasing CR content reduced compressive strength and increased porosity; however, the addition of NS mitigated these effects by densifying the matrix.
