Abstract
Dyeing of protein fiber in non-aqueous media has been investigated using a reverse micellar solution as a dye bath. Conventional acid dye and direct dye solubilized in the interior of reverse micelle was satisfactorily adsorbed on silk even without the presence of auxiliary. It has become obvious that adsorption manner of anionic dye on silk in this system is similar to that in aqueous system. On the other hand, dyeing property of wool with anionic dye in a reverse micellar system was found to be lower than that of silk because of the low fiber swelling. We have found that reactive dyes also have a high ability to adsorb on fiber in a reverse micellar system. Further, fixation of reactive dye on fiber could be attained in reverse micellar system. Fixing ratio of reactive dye on fiber in this system was almost perfect.
