Abstract

Fibre à fonctions antibactériennes et salutaires et son procédé d'obtention. La fibre contient des composés de type fibre protéique et flavone. Des composés de type flavone réduisent les lipides sanguins, la pression sanguine et protègent le foie, tout en ayant des fonctions antibactériennes et antivirales. Lors du port des vêtements obtenus à partir des composés de type flavone, la chaleur et l'éclairage du corps activent les fonctions biologiques des composés qui génèrent alors une action antibactérienne et de stérilisation sur la surface de la peau de manière à traiter les inflammations cutanées. Pendant le contact avec la peau d'un être humain, la fibre peut être dégradée, et les composés de type flavone peuvent pénétrer dans le sang à travers les vaisseaux capillaires de manière à améliorer la capacité de résistance du corps à une maladie.
