Estimating the term…
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.
A method for modifying the surface of a polyester article comprising treating said polyester article with a polyesterase enzyme for a time and under conditions such that the ability to covalently or non-covalently bind compounds to the surface of said polyester article is improved.
A method for improving the uptake of a cationic compound onto a polyester article starting material, comprising the steps of:
The use of polyesterase to improve the ability of a polyester fabric to uptake chemical compounds, such as cationic compounds, fabric finishing compositions, dyes, anti-static compounds, anti-staining compounds, antimicrobial compounds, antiperspirant compounds and/or deodorant compounds.
