Conclusions
Highly disperse pigments of various chemical structures for dyeing viscose fibres in bulk do not exert a marked effect on the change in ripeness and viscosity of the viscose with time.
Complete elimination of the formation of defect cavities and flat fibres in dyeing in bulk can be attained by reducing the ripeness index of the colored viscose.
