The second contents description is incorrect. You don't make bamboo FROM rayon, you make rayon FROM bamboo.
Rayon is a chemically-broken-down and reconstructed fiber made from a cellulose fiber. It could be cotton, it could be wood pulp, it could be grass (bamboo) pulp.
It is less strong and less heat-tolerant than cotton, so it generally should be dried at lower temperatures.
Fun fact - my organic chemistry teacher in high school in the 70's had us make rayon from cotton balls in one lab.
Thanks
@mkc ... I noticed that they had the reversal, and thought it was wrong from the little that I knew, but went with it exactly as given! I normally hang my socks on a drying rack, so have the temp requirement covered! oooooh I like your chemistry teacher ... we never got to do exciting things like that!
So, my next question would be ... Rayon from each of the three sources ...
do they each have different qualities?
or would there be no noticeable difference to the average person aka moi?
Thanks!
