Sisi Tex World - A Guide To Sustainable Fashion Materials

Sisi Tex World says there are two types of textile fibers - natural and synthetic.
The natural fibers come from nature, like cotton and flax or from animals, like silk and wool. Synthetic fibers are, well, made from synthetic fibers.
There's also something that is often referred to as semi-synthetic which are made from natural materials like cellulose from trees but the fibers are made artificially.
The most common synthetic fibers are made from fossil fuels, and the most common material is known as polyester.
