- Abstract
Alizarin, extracted from rubia cordifolia, is a green natural dye. However, its application has been limited by its poor water solubility and pH sensitivity. In this study, linear sulfonic anionic surfactant ( LAS) had been studied as a new dispersant, which promoted the dyeing of alizarin on fabrics under mild conditions. Ultraviolet visible ( UV-vis) spectra and Fourier transform infrared ( FTIR) spectra confirmed appropriate bonding between alizarin and LAS, and the nano particle size analysis showed that LAS could promote the dispersion of alizarin in aqueous solution. Under the optimized condition of alizarin 4. 8% on mass of fabric (omf) and LAS solution 2×10 -2 mol / L, the fabrics were dyed with alizarin at room temperature and pH neutral conditions. The dyed fabrics had good washing fastness and ironing fastness.
