Effect of surfactant on the back-stain of enzyme washed jean

Effects of surfactant concentrations and kinds on the enzyme activity of cellulase and result of enzyme washed jean.The results showed that anionic surfactant had big inhibition effect on enzyme activity of cellulase,cationic surfactant took the second place,and nonionic surfactant had little effect on the enzyme activity of cellulase.Fatty alcohol-polyoxyethylene ether had good anti-backstain effect when the adduct number of polyoxyethylene was relatively low.Macromolecule surfactant PVP also had good anti-backstain effect.The complex of fatty alcohol-polyoxyethylene ether surfactant and fatty ammine-polyoxyethylene ether surfactant had excellent anti-backstain effect.
