2.3 Regenerated materials
Regenerated materials are made by dissolving natural polymers, mainly cellulose, and reforming them into new fibres or films. In fashion, the most common regenerated cellulosic fibres are viscose, modal and lyocell (Lenzing, n.d.-a; Lenzing, n.d.-b; Textile Exchange, 2023). Their environmental performance depends strongly on the source of the cellulose and the way chemicals, solvents, water and energy are managed during production. Closed-loop systems can recover and reuse a large share of processing chemicals, reducing emissions and waste (Lenzing, n.d.-a; Lenzing, n.d.-b).
