Why Is Polyester Shiny?
Polyester is shiny because of its smooth surface. The fabric is made from long chains of polymers, which are melted and spun into fibers. These fibers are then woven into a fabric. During the process, the yarns are stretched, which aligns the molecules and makes the surface of the fabric smooth and reflective. The smoothness of the fabric’s surface causes light waves to reflect off it, resulting in a shiny appearance. Polyester can also be treated with chemicals or coatings to enhance its shine further.
