What is Cuprammonium?
Cuprammonium rayon is a type of rayon fiber that is produced through a unique chemical process. This process involves dissolving the cellulose of a plant product, such as cotton, in a solution of copper and ammonia (cuprammonium solution) known as Schweizer's reagent.
The resulting solution is then extruded through a spinneret and dropped into a bath of caustic soda, which causes the cellulose to solidify and form fibers.
Cuprammonium rayon fibers are known for their lustrous appearance and their ability to be dyed in a range of colors. They are also soft, comfortable, and have good draping qualities. However, cuprammonium rayon is not as strong or durable as other types of rayon fibers and can be prone to shrinking and losing shape when exposed to water.
This fabric is used in a range of textile applications, including apparel, home furnishings, and industrial products. Its softness and draping qualities make it a popular choice for clothing such as blouses, dresses, and lingerie. It is also used in the production of carpets, curtains, and other home textiles.
However, its use has declined in recent years due to environmental concerns associated with the cuprammonium process.
