摘要
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.
