The use of the scanning electron microscope and x-ray analysis to determine the distribution of sulphur and chromium in mordant dyed keratin fibres

Creators

Description

A scanning electron microscope (SEM) and energy-dispersive X-ray system (EDX) has been used to locate chromium in mordant dyed keratin fibres. The chromium in the keratin fibres was found to be evenly distributed and not affected by fibre type, chroming temperature or a steaming process although less chromium was deposited in dyed fibres at a low chroming temperature (25 degrees Celsius). The sulphur in the keratin fibres was similarly located and confirmed that merino wool has a bilateral cortical segmentation (orthocortex and paracortex) while the lincoln wool and mohair examined in the present study, seemed to consist mostly of orthocortical material
