Cotton & Polyester are the most common fibres in our clothes and fabrics. Viscose is a close third. Particularly popular for fast fashion brands due to its soft drape qualities, it is often mixed with Polyester.
The fibre first became commercially available in the 1900’s and was manufactured as a cheaper option to silk. Vintage fans will recognise the fabric as Rayon but this is just the US name for the fibre, it is the same as Viscose. It is derived from a natural substance, cellulose but from that point on the processes to convert wood pulp to a yarn are wholly chemical. If the toxic waste is not dealt with responsibly, the emissions are damaging to the environment and the workers who produce the fabric. Sadly, the wood pulp can also be collected from ancient forests, deforestation being a contributor to climate change.
I have noted the key facts in the below mind map. I do love a mind map to help me absorb the facts, I hope you can make sense of it. My references are below if you need more information.
