Manmade cellulose fibers, derived from natural sources like wood pulp, combine versatility with sustainability in textiles. From soft, absorbent viscose rayon to eco-friendly lyocell, these fibers serve diverse applications in clothing, medical products, and industrial materials. While biodegradable and renewable, their production can involve toxic chemicals and significant resource use, necessitating advancements like closed-loop processes and sustainable sourcing to minimize environmental impact.
