Title: Procédé de production de masse de nano argent, procédé de fabrication de fibre germicide revêtue de nano argent et ses produits
Inventor: HWANG KI YANG
IPC: D06M11/42
Filed: 2005-08-12
Abstract: L’invention concerne un procédé de production de masse de nano argent, un procédé de fabrication de fibre antibactérienne de nano argent et une fibre antibactérienne ainsi fabriquée. On peut produire en masse un nano argent d’une taille inférieure ou égale à 5 nm en appliquant un champ électrique de 10 000 à 300 000 volts (DC) sur deux plaques d’électrode Ag équipées dans un système d’électrolyse d’eau et en ne permettant qu'à un microcourant de s’écouler entre les plaques d’électrode. La fibre antibactérienne revêtue de nano argent s’obtient en appliquant une solution aqueuse du nano argent à la surface des fibres synthétiques, en adsorbant le nano argent sur le tissu en utilisant un processus sélectionné parmi la fixation thermique, la radiation haute fréquence, le bouillonnement et des combinaisons de ceux-ci ; et en réalisant une post-finition à 160 - 200°C. Et ainsi, une fibre antibactérienne fabriquée de cette manière peut être une solution fondamentale aux problèmes des fibres synthétiques, à savoir une fonctionnalité anti-transpirante médiocre et la production d’électricité statique.
