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.
  • biostatics microorganisms
  • 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.
  • the international patent application WO 2006/071452 A2 The use of polyester amides for the temporary or permanent finishing of textile surfaces is known.

  • compositions presents no difficulties and can be carried out in a manner known in the art, for example by spray-drying or granulation, thermally-sensitive ingredients optionally being added separately later.
  • compositions in the form of aqueous or other conventional solvent-containing solutions are particularly advantageously prepared by simply mixing the ingredients, which can be added in bulk or as a solution in an automatic mixer.
  • the agents are preferably in the form of powdered, granular or tablet-shaped preparations which are compacted in a manner known per se, for example by mixing, granulating, roll compacting and / or by spray-drying the thermally stable components and admixing the more sensitive components, to which in particular enzymes, bleaching agents and bleach-activating agents are to be expected.
  • a process comprising an extrusion step is preferred.
  • a tablet thus produced has a weight of 15 g to 40 g, in particular from 20 g to 30 g, with a diameter of 35 mm to 40 mm.
  • the cellulose derivative Polyquaternium-67 (quaternized hydroxyethylcellulose with cationic substitution by trimethylammonium and dimethyldodecylammonium, Softcat® SX 400 H) was forcibly applied in 1% strength solution to cotton lobes, the lobules were dried and then treated with the test bacterium Pseudomonas aeruginosa. For this purpose, the test bacteria were previously cultivated overnight on TSA agar medium and then washed away with the tryptone-NaCl from the agar plates. There were dilution steps in tryptone-NaCl. The final dilution step was carried out in PBS buffer (1-fold).
