Fastness
Wash-fastness (WF) and lightfastness
(LF) results of the dyed fabrics
with and without chitosan treatment are
indicated in Table 5. The dyed fabric
treated with chitosan improved both the
light-fastness by one unit on the standard
blue wool scale and wash-fastness by one
unit on the standard grey scale compared
with the dyed fabric without chitosan. In
addition, the results indicate that the use
of mordants also improved the wash
