A reprocessed cellulose fiber, made from wood pulp, is
rayon, also known as viscose. It was the first fiber produced, and yet it dyes
and looks like a natural fiber as it is made of cellulose. Like cotton, it
absorbs moisture from the skin.
Currently, the bulk of bamboo is rayon, so you're on the right page for information on how to dye bamboo.
How to Dye and what color to choose?
With the same dyes that work on cotton, Rayon may be dyed,
but also creates darker, more dazzling colors. With cold water fiber resistant colorants,
Rayon dyes most beautifully. Direct dyes and all-purpose dyes may also be colored,
but the colors from such less wash-fast dyes will fade easily unless they are
corrected by a cationic after treatment. It is also possible to use Vat dyes to
dye rayon, including indigo, and naphtha dyes. If you use organic products on
rayon, premordant it as cotton would be; as wool does, it will not bind to
other natural dyes.
Way to Dye
Using a fiber reactive dye, such as Procion MX dye, is the
easiest way to dye rayons. For directions, see How to Hand Dye. Use a washing
machine or bucket, with high water to fabric ratio, and continuous stirring,
to dye a single solid color.
Look out for damage
Compared with other cellulose fibers, Rayon has one major
flaw: it has very low wet strength. When rayon is damp, it can be very quickly
torn or abraded.
You have to take caution to stop stressing the fabric if you
dye rayon or machine wash it. Hand washing is better to do separately than
machine washing. Use the delicate cycle when you do machine washing, and expect
an occasional error. Rayon fabric manufacturer never uses heavy clothes,
such as blue jeans, to wash rayons. Before cleaning, sorting through weight is
quite necessary.
