Rayon shrinks quickly, so it is important to be careful with this fabric.
One of the notable advantages of Rayon is its excellent moisture absorption, keeping the wearer comfortable in humid environments. It also exhibits good breathability, allowing air to circulate through the material, helping the wearer avoid feelings of stuffiness and heat.
