Aggregation of dye in semicrystalline polyamide films and hair and its influence on polyamide film morphology
The self-aggregation of three industrially relevant dyes in polyamide (PA) films (PA-6 and PA-(6,6)) and in goat hair will be studied. Dye molecules are expected to diffuse into the amorphous regions of the PA film and subsequently change the morphology of the whole film. The scattering length density of the amorphous phase will be varied by introducing H2O and D2O at varying ratio into this phase. This permits to collect data on the same system but at variable contrasts. This will generate a better understanding of dye diffusion, adhesion and morphological changes in the PA film and in hair and help to quantify phenomena that limit literature-described models for diffusion during dyeing processes.
