Rayon is a versatile man-made fibre that can be engineered to mimic the characteristics of natural fibers like cotton or silk. During the manufacturing process, the filament can be manipulated and modified to control specific physical attributes, including lustre, strength, elongation, filament size, and cross section, to achieve the desired aesthetic or functional result.12

Because rayon is composed of regenerated cellulose, it naturally shares many properties with cotton, making it suitable for applications where cotton is typically used. To resemble silk, manufacturers adjust the fibre's properties—such as its lustre and cross-sectional shape—during the extrusion and coagulation phases to replicate the smooth, reflective appearance of silk filaments. Additionally, techniques such as crimping can be used to alter the texture of the fibre, allowing it to take on different physical qualities depending on the intended end use.123
