Recovery, separation, and quality-based reutilization of PET in waste blended fabrics: A review

The high-value use of PET, one of the key ingredients in blended fabrics, will be a crucial component in fostering the development of a closed loop in the textile industry cycle. This study examines the problem of separating and reusing waste blended fabrics, presents the most recent developments in this area, thoroughly examines the methods used to separate PET and cotton, assesses the economic and industrial viability of reusing the components, and concludes with suggestions for solutions. With the goal of transforming the textile industry from a polluter to a major contributor to accelerating the world's admirable aspirations to achieve the United Nations Sustainable Development Goals (SDGs) by 2030, this review serves as a catalyst for the industry by offering a theoretical reference for the separation, recycling, and reuse of waste blended fabrics.
