Abstract

The textile industry's transition toward a circular economy necessitates effective recycling of pre-consumer waste streams, particularly roving waste generated during spinning. This review provides a comparative analysis of mechanical and solvent-based recycling technologies for processing roving waste, evaluating their principles, efficiencies, and suitability for fiber recovery. Drawing on recent literature (2019–2025) and industrial case studies, including data from Uzbek spinning mills, the paper examines the strengths and limitations of each approach. Mechanical recycling, while cost-effective and widely adopted, often compromises fiber length and quality. In contrast, solvent-based regeneration offers the potential to produce fibers with virgin-like properties but faces challenges related to cost and solvent recovery. The comparative techno-economic assessment reveals that mechanical processes have lower immediate costs, whereas advanced solvent-based methods may yield higher-value end products, albeit with greater capital investment. The review concludes by identifying research gaps and proposing pathways for integrating these technologies to enhance material recovery and support sustainable textile manufacturing.
