Abstract
In this study, Marseille soap and Na2CO3 are used for self-dyed silk degumming and evaluated the influence of technological parameters on the degumming efficiency and color intensity of self-dyed silk. Self-dyed silk results from a new dyeing method; this is a green and without-water dye. Its mechanism is based on feeding silkworms with mulberry leaves supplemented by the Rhodamine B dyestuff; colored silk was then treated at different concentrations and time treatment. Xrite color i5 colorimeter, Scanning Electron Microscope (SEM), and Fourier transform infrared spectroscopy (FT-IR) were respectively used to evaluate the color intensity, the treatment efficiency, and the structural characterization of self-dyed silk. The results show that the higher the solution concentration and treatment time, the higher the weight loss ratio and the lower the color intensity. In addition, degumming with Na2CO3 retains the color of silk better than it with Marseille soap. The results are also for reference in selecting the appropriate treatment process for this new material.
