The modernization of textile machinery requires engineering solutions that reduce friction, minimize wear, and increase operational efficiency under high-speed and dust-intensive working conditions. This study proposes an optimized modernization methodology based on replacing conventional steel components with advanced composite materials in critical frictional units such as navoy shafts, rollers, and polymer–metal bushings. A combination of experimental tribological testing and analytical modeling was employed to evaluate several composite systems, including phenolic-fabric laminates, polyamide-6, basalt-fiber, and carbon-fiber reinforced materials. Tests were performed at loads of 50–200 N and sliding speeds of 0.5–2.5 m/s to quantify friction coefficient, wear rate, temperature rise, and surface morphology. Mathematical models describing frictional behavior, Archard-based wear prediction, and torsional strength of composite-coated hollow shafts were developed to support optimization. Results demonstrate that composite–polymer friction pairs reduce wear by 45–65%, friction coefficient by 30–50%, and energy consumption by 8–12%, while decreasing component mass by up to 35%. These findings confirm that composite-based modernization significantly enhances durability, thermal stability, and energy efficiency, offering a practical and economically viable upgrade pathway for existing textile production systems.
