Cuprammonium cellulose, also known as cuprammonium rayon or cupro, is a type of semi-synthetic cellulose fiber derived from cotton linters or wood pulp. It is produced through a chemical process that involves treating the cellulose with copper hydroxide and ammonia, which results in a solution that can be extruded into fibers. These fibers are known for their softness, lustrous appearance, and high moisture absorbency, making them suitable for a variety of applications, including textiles, where they are often used in clothing due to their comfort and drape. Cuprammonium cellulose is also biodegradable and has a lower environmental impact compared to some synthetic fibers.
