Silk and polyester are two widely used fabrics in textile industry. Silk is often used in high-end bed sheets & delicate clothing like silk nighties; while polyester is often used in outerwear because of its high tenacity and durability. Polyester is a strong fiber and consequently can withstand strong and repetitive movements. The main difference lies in origin, one is from natural fibers, the other is artificial.
