Degradable textile materials based on renewable resources have become a research hotspot in the field of textile materials science and engineering at home and abroad due to their significant advantages in sustainable development, recycling, and environmental friendliness. This review summarizes the types and preparation methods of renewable resource-based biodegradable textile materials. It further discusses their structural characteristics, performance regulation mechanisms, and recent advances in applications across apparel, home textiles, medical care, and industrial sectors. The resource characteristics, molecular structures, modification strategies, and their effects on degradation and mechanical properties of different raw materials such as natural cellulose, protein polymers, polysaccharides, polylactic acid, etc. The degradation mechanism, environmental adaptability, and life cycle assessment results of biodegradable textile materials; Finally, the current technological bottlenecks, such as high production costs, insufficient performance stability, and poor controllability of degradation rates, were analyzed, and future development trends were proposed, including green synthesis, functional modification, composite design, and intelligent applications.
