摘　　要：2020年,我国大陆纺织纤维总产量超过6 800万t,其中聚酯纤维超过4 900万t,而纺织品的回收再生仅430万t,与循环经济及可持续发展的目标相差甚远。文章从纺织品回收再生过程介绍了相关技术进展,重点描述近10余年来聚酯(PET)、聚酰胺(PA)、纤维素纤维纺织品及混纺织物、高性能纤维复合材料的分拣识别、纤维分解分离和再生技术。得出:我国在纺织品回收再生产业链中的技术进步是令人鼓舞的,一些原生纤维加工企业已经开始关注纺织品循环经济,兼顾生产过程的环保和低能耗,并积极参与物理、化学回收再生,专业的纺织品回收再生企业也在积极开拓“高值化”应用市场;纤维“永久”功能性和织物“时效功能性”技术将随着产业链可持续发展目标的推进得到更合理的选择。In 2020,the total amount of textile fibers used in China’s mainland exceeded 68 million tons.Among them,polyester fibers exceeded 49 million tons,while the recycling of textiles was only 4.3 million tons,far from the goal of a circular economy and sustainable development.From the perspective of the textiles recycling process,the paper introduces the relevant technical progress,and mainly focuses on the sorting identification,fiber decomposition and separation and recycling technology of polyester,polyamide,cellulose fiber textiles,blended fabrics,and high-performance fiber composites in the past decade.Research results indicated that the technological progress of China in the textiles recycling industry chain is encouraging.Some fiber processing enterprises have started to pay attention to the textile circular economy,taking into account the environmental protection and low energy consumption of the production process,and actively contributing to physical and chemical recycling;professional textiles recycling enterprises are also actively developing the high-value application market;the “permanent” functionality of fibers and the “temporary” functionality of fabrics will provide more reasonable choices with the promotion of sustainable development goals of the industry chain.
