The textile industry is undergoing a transformation with the advent of Industry 6.0, integrating AI-driven automation, IoT, CPS, and quantum computing into smart textile manufacturing. The chapter discusses advancements in spinning, weaving, knitting, dyeing, finishing, and retail, emphasizing sustainability, efficiency, and precision. AI-powered fiber blending and real-time monitoring reduce defects, while automated spinning and weaving enhance productivity. Smart dyeing technologies, such as supercritical CO₂ dyeing and plasma-enhanced finishing, minimize water usage and eliminate toxic effluents. Industry 6.0 innovations in digital textile printing cut CO₂ emissions, while blockchain-based supply chain traceability ensures ethical sourcing and transparency. The chapter also explores AI-driven waste management, enzymatic textile recycling, and carbon capture in dyeing processes, contributing to a circular economy. The integration of robotics in textile assembly, quantum-enhanced material science, and real-time defect correction is revolutionizing textile production. AI-driven demand forecasting in retail reduces overproduction, optimizing supply chains. The future of Industry 6.0 in textiles is focused on net zero waste manufacturing, predictive maintenance, and climate-resilient production systems, aligning with SDG 9, 12, and 13 for sustainable industrial development.
