Patent

CA 2221138

Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is therby prohibited. Laminates of the fabric with other materials are also disclosed.

L'invention concerne un tissu comprenant un adsorbant microbien et qui est capable de créer une barrière antimicrobienne, tout en laissant passer la vapeur d'eau. Ce tissu est constitué par une pluralité de fibres qui définissent au moins un passage microporeux permettant à une communication de s'effectuer à travers le tissu entre sa première et sa deuxième surface respectives. Un partie du passage microporeux, en particulier, est définie par l'adsorbant microbien, de sorte que les microbes qui tentent de passer à travers le tissu par ledit passage, doivent passer en proximité étroite avec l'adsorbant microbien. De ce fait, l'adsorbant microbien interdit le passage aux microbes, par adsorption de ces derniers, qui ne peuvent plus traverser le tissu. L'invention concerne également des stratifiés de ce tissu avec d'autres matériaux.
