Stability of Blueberry Peel Pigment and Its Application in Dyeing of Tussah Silk
In order to enrich the color of tussah silk and utilize blueberry resources, the stability of pigment components in blueberry peel on pH and metal ions was studied, and the application property and dyeing kinetics of blueberry peel pigment on tussah silk were explored. The results showed that the change in medium pH and metal ions Al3+or Fe2+could cause the change of the absorption spectrum of blueberry peel pigments in the UV-VIS range and produce different col-ors. Blueberry peel pigment had good dyeing performance on tussah silk, and the fabric could obtain higher color depth when pH=3. The dyeing process of blueberry peel pigment on tussah spun silk was consistent with the quasi-second-or-der kinetic model, and with the increase of temperature, the dyeing rate of pigment on the fiber increased, while the half-dyeing time decreased. The use of metal salt Al2( SO4 ) 3 or FeSO4 as mordant could improve the color depth of the sam-ple, and the mordant agent and mordanting process had a significant impact on the tone of the samples. The color fast-ness of the mordant dyed tussah silk fabrics could reach level 3. This study can provide reference for the comprehensive development and utilization of blueberry resources and the preparation of ecological textiles.
