  • the water-repellent bristle according to the present invention has a water repellency in which the water absorption ability is significantly reduced, and thus the amount of remaining water in the bristles after brushing is greatly reduced, and the rate of evaporation of the water is very fast, thereby inhibiting the growth ability of bacteria. Bacterial infection can be prevented. Therefore, the water-repellent toothbrush including such a water-repellent bristles is very excellent compared to the conventional toothbrush with a bacteriostatic effect.

Abstract

La présente invention concerne une soie de brosse à dents présentant des propriétés hydrofuges et une brosse à dents la comprenant. Une soie de brosse à dents comprenant un composant hydrofuge, et de préférence un perfluorocarbone, présente des propriétés hydrofuges réduisant considérablement sa perméabilité à l'eau, ceci pouvant ainsi éliminer la possibilité de propagation de microbes et par conséquent permettre d'éviter toute infection microbienne de la bouche étant donné que l'on obtient non seulement une réduction notable de la quantité d'eau restant dans les soies de la brosse à dents mais également une vitesse d'évaporation très élevée suite au brossage des dents. En outre, la présente invention concerne une brosse à dents hydrofuge comprenant de telles soies de brosse à dents hydrofuges.
