ABSTRACT

The dyeing on cellulose fibers such as cotton and viscose viscose rayon was carried out by the use of solution extracted from natural fresh leaves of indigo plant under several dyeing conditions. The dyeing affinity of viscose rayon was higher than that of cotton. The total K/S value of dyed fabrics was considerably increased with repeated dyeings, while a dyeing time has a little influence on it. Both fibers were hardly dyed by indigo at 60 and cotton was dyed better at 40 than at 20 , but in viscose rayon, a little difference of total K/S was shown between 20 and 40 . The color change of dyed fabric according to dyeing conditions was evaluated by the CIELAB color system. viscose rayon had a lower b* so that it looked bluer than cotton and when the celluose fibers were dyed by indigo plant at the lower temperature, the bluer it looked. By repeated dyeings the b* value of dyed fabrics was much increased but the a* value was little influenced and in case of viscose rayon the change was considerable.
