UV-Vis microspectrophotometry as a method of differentiation between cotton fibre evidence coloured with reactive dyes

摘要

The main purposes of this study was to assess the usefulness of microspectrophotometry (MSP), both in the ultraviolet (UV) and visible (Vis) range for discriminating single cotton fibres dyed with reactive dyes coming from the same manufacturer, as well as the possibility of evaluation of the concentration of dye in an examine fibre. This study utilised woven cotton fabrics dyed with different concentrations of onecompound reactive dyes with the commercial name Cibacron (R) (at present Novacron (R)) as the focus of the MSP analysis.
