Abstract
L'invention a trait à une matière barrière respirante, qui comporte une première couche non tissée et un premier film microporeux, qui sont liés ensemble pour que soit formé un stratifié composite. Un second film microporeux et une seconde couche non tissée sont liés au stratifié composite afin que soit formée la matière barrière, de façon que les films soit disposés entre les couches non tissées. Le stratifié composite est lié au second film et à la seconde couche non tissée, ce qui crée des points de liaison dans la matière et des espaces vides entre les premier et second films. Les espaces vides entre les films peuvent améliorer les propriétés de protection contre les liquides et les virus de la matière barrière, en créant une frontière qui réduit au minimum le passage de liquides et/ou de constituants viraux à travers la matière barrière.
