Investigation of Thermal and Structure Properties of Silk Dyed with a Natural Dye

Abstract

The present work aimed to dye silk fabric with natural dye extracted from the Artemisia Herba Alba plant from its leaves on pure silk dyeing fabrics with different dyeing conditions such as time, temperature, and pH value in the presence of Alum as a mordant, which had given different colors and shades to promote the use of natural silk fiber. Optimum results were obtained. Silk fabric was dyed using pH 5 for 45 minutes at temperature 80oC and 1:40 liquor ratio. Finally, the dyed mordant samples were thoroughly washed and dried at ambient conditions. The results obtained us successfully characterized dyed silk fabric by studying with a Fourier Transform Infrared thermogravimetric (TGA) properties, (FTIR) analysis technique, and X-ray diffraction (XRD). Improvement in the dyeing process may have been attributed to the improvement in the molecular structure of the chemical bonds in silk fabrics. This work gives an opportunity to use a new traditional natural dye that meets the future environmental technology that exhibited fantastic dyed patterns of high quality.
