Paper Title:
Study on Extracting of Sappanwood Natural Dye by Cellulase
  Abstract

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.
