摘　　要：我国是纺织服装最大的生产国和消费国,纺织品的年废弃量超过2600万t,未妥善处置会造成严重的资源和环境问题。国家十分重视废旧纺织品绿色循环体系的建立,已形成多种回收利用途径并实现了产业化。涤纶在化纤中占比最大,发展废旧涤纶纺织品循环利用技术对建立废旧纺织品循环利用体系尤为重要。废旧涤纶纺织品的回收利用方式主要有物理回收、化学回收、生物回收和物理化学回收等。综述了废旧涤纶纺织品的回收利用技术,并介绍了企业实际案例,期望为建立绿色健全的废旧纺织品循环体系提供支撑。China is the biggest producer and consumer of textile and clothing,and the annual output of waste textiles is more than 26 million tons,which will cause serious resources and environmental problems if the waste textiles were not properly disposed.The establishment of green recycling system of waste textiles are highly valued,which has formed a variety of recycling methods which have been realized industrialization.Polyester takes up more than 80%of the total amount of chemical fiber.Therefore,developing recycling technology of waste polyester textiles is particularly important for establishing recycling system of waste textiles.The recycling methods of waste polyester textile mainly includes physical recovery,chemical recovery,biological recovery and physicochemical recovery.This study summarized the recycling technology of waste polyester textiles,and introduced the practical cases of company,which provides support for the establishment of green recycling system of waste textiles.
