The textile, apparel, and fashion industry has increasingly emphasized traceability and transparency in its processes and raw materials supply chains. This change aims to reduce environmental impacts, enhance labor rights in supply chains, and ensure product safety. Key environmental concerns include sustainable fiber sourcing, minimizing resources use, production emissions, transportation carbon footprints, and textile waste management. Improved traceability enhances visibility, transparency across value chains and consumer trust, while preparing companies for future regulations and addressing counterfeit products. Traceability and transparency are crucial for meeting sustainability goals set by the European Commission and the United Nations 2030 Agenda for Sustainable Development. Adopting sustainable practices, such as using organic or recycled materials and promoting fair trade, is crucial for fashion designers, brands, and suppliers. The main objective of this study was to analyze the knowledge of first cycle fashion design students regarding the concept of traceability and its role in textile and fashion sustainability and circularity. This study was conducted through methods of information interpretation and data analysis, which was obtained through a questionnaire that was applied to textile and fashion students. There were 145 participants, resulting in 105 responses. The results obtained indicate that students recognize the importance of traceability but have limited familiarity with platforms, technologies, and their influence on product circularity and ecological design. Fashion designers and students are encouraged to prioritize the understanding of traceability's technical aspects to promote transparency and sustainability across the fabric and apparel production chain.
