A Microscopical Study of the Pathway for Diffusion of Rhodamine B and Octadecylrhodamine B into Wool Fibres

The pathways for the diffusion of the basic dyes rhodamine B and octadecylrhodamine B into wool under aqueous and non-aqueous dyeing conditions have been investigated. The distribution of each dye within the fibre at various stages of the dyeing process was monitored by fluorescence microscopy. The optimum dyeing conditions for the attainment of various dye distribution patterns within the fibre are reported
