Study on Extracting of Sappanwood Natural Dye by Cellulase

Abstract:

Article Preview

The conditions for extracting sappanwood pigment by cellulase were investigated. The results showed that, compared with traditional water extract method, the absorbance of sappanwood extract raised 35%. Single factor analysis method was done to the enzymatic process, and the optimal extracting conditions were bath ratio 20: 1, mass ratio of sappanwood and cellulase 100:1, enzymolysis at 50°C for 80min, extract at 80°C for 60min. Silk fabric was dyed with the sappanwood extract, the fastness was above grade 3-4.
