"This research has explored the effect of laccase (Denilite II S) on the physical properties of the wool fabric and confirms the anti-felting of wool. In the experiment, laccase was applied to a wool fabric and different characteristics including weight loss, strength, alkali solubility, felting shrinkage, water drop absorption, and dye ability with madder were studied," scientists in Iran report (see also Enzyme Research).
"The surface morphology of the wool fabrics was also observed by scanning electron microscope. The results indicated that the wool fabric treated with laccase has a higher water drop absorption, lower felting shrinkage, and lower values of a* and b*. Treatment of a wool fabric with 10% or lower percentage of laccase reduced the fabric weight but increased the tensile strength. However, using higher concentration of laccase reduced fabric weight and tensile strength," wrote M. Montazer and colleagues.
The researchers concluded: "The dyeing of laccase pre-treated wool fabric with madder indicated a lower lightness."
Montazer and colleagues published their study in Applied Biochemistry and Biotechnology (Treatment of Wool with Laccase and Dyeing with Madder. Applied Biochemistry and Biotechnology, 2009;158(3):685-693).
