Q
how is rayon yarn made
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Rayon yarn is derived from cellulose fibers, typically sourced from wood pulp or bamboo. This process involves several steps to transform natural materials into a versatile textile. First, the raw material is chemically treated to create a viscose solution. This involves breaking down the wood or bamboo into its basic cellulose components through a process called cooking, using alkali and sulfuric acid. After purification, the viscose is forced through spinnerets, which are shower-head-like devices, into a bath of dilute sulfuric acid. This coagulation step forms continuous filaments. The resulting fibers are washed, bleached, and dried before being spooled into yarn. While rayon is eco-friendly due to its plant-based origin, the manufacturing process uses harsh chemicals that require careful management to minimize environmental impact.
