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.
L'invention concerne un procédé servant à améliorer la fixation d'un composé cationique sur un matériau de départ d'un article de polyester, ce qui consiste à : (a) utiliser une enzyme polyestérase ; (b) mettre en contact ladite enzyme polyestérase avec ledit matériau de départ de l'article de polyester dans des conditions et pendant une durée appropriées pour que ladite polyestérase produise une modification de surface dudit matériau de départ de l'article de polyester et, par conséquent, un polyester modifié en surface ; (c) mettre en contact ledit article de polyester modifié, consécutivement ou simultanément à l'étape (b) avec un composé cationique, ce qui permet d'augmenter l'adhérence dudit composé cationique audit polyester modifié par rapport au matériau de départ du polyester. Elle concerne également un procédé servant à augmenter la capacité hydrophile d'un polyester afin d'améliorer les caractéristiques d'un textile, telles que la résistance aux taches, la mouillabilité et/ou l'acceptation des teintures.
