Now, apart from being labelled "Rayon", it also says it is "viscose"
So my question is: is this a natural fibre or not
Viscose is the liquid from which rayon is extruded, so it would have
started out from wood pulp, but then gone through the addition of various
chemicals that disolve the cellulose (usually sodium hydroxide and
something else that I can't remember). This liquid is then extruded into
an acid bath where further chemical reactions convert it back to cellulose.
So, it is neither natural nor artificial, but a combination of both.
