Definitions

  • the present invention relates to the use of certain polymers to reduce the adhesion of microorganisms to textiles.
  • Microorganisms such as bacteria, fungi and viruses can colonize household and textile surfaces. Bacteria and fungi can also multiply on such surfaces. This can result in hygiene risks, but also lead to unaesthetic microbial deposits, so-called biofilms. The occurrence of microbially induced, especially bacterially caused bad odors is possible. Garments made of delicate materials such as silk or microfibers can only be washed at 30 ° C or 40 ° C. It is possible that thereby fungi, such as the human pathogenic Candida albicans, and bacteria are not always killed sufficiently. In particular, after a fungal infection can come by such adhering to garments, not killed fungi to a reinfection.

  • biocides used for example in detergents and cleaners enter the wastewater after use and may impair the function of the microbial treatment stages in the sewage treatment plants.
  • selection pressure on the microorganisms for resistance formation is greatly increased, so that after some time new antimicrobial substances must be found that act against resistant microorganisms. It is therefore desirable to have biorepulsive substances instead of biocidal or biostatic substances which prevent the adhesion of the microorganisms without physiologically impairing the microorganisms.

Cela peut être obtenu sensiblement par l'utilisation de copolymères greffés ou blocs contenant une base de greffage polyalkylène glycol ou au moins un bloc polyalkylène glycol et, en tant que branche greffée ou en tant que bloc distinct, des composés polymérisés qui sont dotés d'au moins une liaison double oléfiniquement insaturée et qui présentant un groupe polaire.
