Preparation,structure and properties of ε-polylysine grafted silk fabric with laccase

摘要：

　　Silk fabric was treated with laccase and then grafted by ε-polylysine (ε-PLL).The optimal enzymatic reaction condition was investigated through the change of dissolved oxygen concentration during the enzymatic reaction.The results of amino acid analysis and SEM of fmished silk fabrics indicated that the ε-PLL was grafted onto silk fabrics.Differential scanning calorimetry indicated that the thermal stability performance of the finished fabric was slightly improved.The crease resistance of the finished silk increased, especially the wet wrinkle resistance property of the finished silk fabric was significantly improved.The gas permeability, strength and whiteness slightly decreased, which hardly impact the wearability of the fabric.
