    • A method is provided for improving the uptake of a cationic compound onto a polyester article starting material, comprising the steps of: (a) obtaining a polyesterase enzyme; (b) contacting said polyesterase enzyme with said polyester article starting material under conditions and for a time suitable for said polyesterase to produce surface modification of said polyester article starting material and produce a surface modified polyester; (c) contacting said modified polyester article, subsequently or simultaneously with said step (b) with a cationic compound whereby adherence of said cationic compound to said modified polyester is increased compared to said polyester starting material. Also disclosed is a method for increasing the hydrophilicity of a polyester to improve fabric characteristics such as stain resistance, wettability and/or dyeability.
    • 提供了一种改善阳离子化合物在聚酯制品起始原料上的吸收的方法,包括以下步骤:(a)获得聚酯酶; (b)使所述聚酯酶与所述聚酯制品原料在适于所述聚酯酶的条件和时间下接触以产生所述聚酯制品原料的表面改性并制备表面改性聚酯; (c)随后或同时与所述步骤(b)将所述改性聚酯制品与阳离子化合物接触,由此所述阳离子化合物与所述改性聚酯的粘合性相对于所述聚酯起始材料增加。 还公开了提高聚酯的亲水性以提高织物特性如耐污染性,润湿性和/或染色性的方法。
