Hi everyone, I was just wondering if there was any general chemical structure/formula for any type of natural fibres?  Generally silk or cotton.  I've been trying all day but haven't had any luck.  I'm just trying to get a structure where the fibre is flammable, soft and is polar.  Basically, a lewis structure of the molecule which a natural fibre may be based on, thanks!

Cotton is almost completely composed of cellulose, which is a polymer of glucose.  If you search for cellulose you should find images and molecular structures quite quickly.
