Fabric Friday: Rayon continued, plus acetate

[retro ruth]

Grateful for all your info.! Thing is, I've been telling people, for years, that rayon is a natural fiber. Why is it not considered a natural fiber if it comes from trees? Can't get more " natural " than a tree! Lol
Thank you! I don't want to misinform my customers.

Rayon is sometimes called a semi-synthetic. It is made from plants, but it differs from other natural plant fibres, such as cotton, because it's made by a chemical process. Cotton or linen are spun using only mechanical, (or even purely manual) processes. I find rayon breathable, which is what I love about natural fibres.

The term "manufactured" is most accepted for this list of fabrics. All of these are made of polymers, but rayon/viscose and acetate are most natural in that they are manufactured from biopolymers. The rest are made of synthetic polymers.

I have always though that modal/tencel/lyocell were bio based as well.

Do they occupy a space somewhere between biopolymer and synthetic polymer?

They are bio based because they are all forms of rayon—just different processes in manufacturing.
