Abstract

La présente invention concerne une fibre revêtue d'un photocatalyseur, munie de films protecteurs, qui comprend un substrat en fibre, un film protecteur sous-jacent, un revêtement photocatalytique et un film protecteur de surface. Selon l'invention, un procédé pour fabriquer la fibre comprend l'application directe d'une solution d'un composé à base d'alcool sur le substrat en fibre afin de former un film protecteur sous-jacent. Puis, elle comprend le revêtement d'une solution photocatalytique sur le film protecteur sous-jacent formé afin de former un revêtement photocatalytique de telle sorte que le substrat en fibre peut éviter d'être dégradé par le photocatalyseur revêtu. Enfin, elle comprend l'application d'un film protecteur de surface sur le revêtement photocatalytique formé. Ainsi, l'adhérence de souillures peut être grandement réduite.
