[ 1 ] - Application of Derivative Spectrophotometry to Determine the Relation Between Color Intensity and Dye Concentration of Madder

The Derivative Spectrophotometry usually improves resolution bands, eliminates the influence of background and provides more defined fingerprints than original spectra, hence enhancing the detectability of minor spectral features. In this work, different madder types were collected and applied for dyeing woolen yarns used in Persian carpet in conventional pre-mordanting and dyeing process with ...
