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. 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. The dyeing of laccase pre-treated wool fabric with madder indicated a lower lightness.
本研究探讨了漆酶（Denilite II S）对羊毛织物物理性能的影响，并证实了羊毛的防毡缩性。在实验中，将漆酶应用于羊毛织物，并研究了包括失重、强度、碱溶解度、毡缩率、水滴吸收和与茜素染料的上染能力等不同特性。还通过扫描电子显微镜观察了羊毛织物的表面形态。结果表明，用漆酶处理的羊毛织物具有更高的水滴吸收率、更低的毡缩率和更低的 a和 b值。用 10%或更低百分比的漆酶处理羊毛织物会减轻织物重量，但会增加拉伸强度。然而，使用更高浓度的漆酶会减轻织物重量和拉伸强度。用茜素对漆酶预处理的羊毛织物进行染色表明颜色明度较低。
