Color Parameters and Optical Properties of Silk Fabrics Dyed with Natural Dye (Artemisia Herba-Alba)

Abstract

The present work deals with the evaluation of the color parameters and fastness properties of silk fabrics dyed with a natural dye that extracted from the Artemisia Herba-Alba plant at different dyeing conditions such as pH values, temperature, and dyeing time. The reflectance spectra of pure blank and dyed silk fabrics were followed using the spectrophotometer technique. The effect of different dyeing conditions on the optical parameters (CIE tristimulus values, color parameters, absorption coefficient, and color strength) was determined before and after exposure to artificial daylight for 160 hrs. The obtained results indicate that the silk fabrics were highly dependent on either of these different dyeing conditions and/or artificial daylight exposure. Improvements in the dyeing process were produced which may be due to the change in the molecular configuration by variation in the chemical bonds in silk fabrics. The present work gives a chance to use a new traditional natural dye that meets the environmental future technology of high-quality fantastic dyed patterns. Also, fastness properties to perspiration and washing were tested for all silk fabrics under investigate
