The Journey of Rayon From Silk Alternative to Everyday Fabric

The video explores the history and significance of silk, leading to the development of rayon as an alternative. Rayon, a semi-synthetic fiber, was first industrialized in the late 19th century. The production process involves converting cellulose from plants into fibers. Rayon is widely used in textiles due to its silk-like appearance and ability to blend with other fibers. However, it lacks the tensile strength of fibers like nylon.
