Rayon fiber cross section
WebApr 18, 2024 · Rayon is what’s known as a semi-synthetic cellulosic fiber. It’s made from natural materials, most commonly wood pulp. The wood gets dissolved and chemically treated to become cellulose. The cellulose gets spun into threads and then those threads make up rayon fabric. If you start reading labels, you’ll notice that rayon shows up in lots ...
