Polyolefin fibers are
hydrophobic, and the
molecular chains within the
fiber are tightly packed. Therefore it is
extremely difficult to dye polyolefin fibers or
to increase their affinity to
dyes. Colored inorganic salts or
stable organometallic pigments have been
added to the
polymer melt prior to fiber
spinning to color the
fibers. Also, nonvolatile acids
or bases or materials such as polyethylene
oxides or metal salts have been added to the polymer prior to fiber formation to
increase the affinity of the fiber
for disperse, cationic,
acid, or
mordant dyes. Polyolefin fibers can
be chemically grafted
with appropriate monomers
after fiber formation to improve their
dyeability.
Hi,
ReplyDeleteThanks for this post! Just wondering - if I were to dye a rug made of Poly Olefin, what are the chances that I'd be able to fade the color using bleach? Would bleaching the rug make it easier for me to then dye it?
Thanks
