Research progress in resource recycling based on waste textiles

With aim to achieve the recycling of waste textiles and promote the construction of closed-loop system of textile industry chain, the conventional recycling framework of waste textiles was summarized based on the existing achievements. The resource recycling methods including primary recycling, physical recycling and chemical recycling were examined, and the advantages and disadvantages of each recovery process were discussed. At the same time, the research progress in the recycling process of single component fiber such as cellulose fiber, polyester fiber, protein fiber, and the typical blended textiles were described. Furthermore, the research progress in the preparation of functional materials based on waste textiles, and their applications in fields such as sound insulation materials, foam materials, solar evaporation and capacitive materials were introduced. Finally, the review pointed out that the comprehensive evaluation system of waste textiles is the key to increase speed and improve quality of resource recycling and to achieve industrial production. © 2022, Periodical Agency of Journal of Textile Research.
