Semen Litchi Extract Dyeing on Silk Fabrics

Article Preview

Abstract:

The extraction of natural dye from semen litchi was studied, and the stability and dyeing ability of the dyestuff for the silk fabrics were also investigated. The results showed that the extraction efficiency using ethanol and sodium hydroxide was better than other solvents. The results indicated that the stability of the semen litchi stuff was good. The optimum direct dyeing process is at 90°C for 45 min with pH 4. Meanwhile, the color yield and color fastness of dyed fabrics can be improved by mordant dyeing.
