The outer shell consists of a plain weave multifilament fabric
derived from aramid, polymide, polyamide or polybenzimidazole yarns.
The inner sheet is a woven, non-woven or knitted material. The two sheets
are laminated with an adhesive which enables the two sheets to be
laminated in such a manner that the two sheets are non slipping with respect
to one another while enabling the laminate to be air permeable with a
minimum of ten (10) cubic feet per minute (CFM), when tested in
accordance with ASTM D737.
L'invention porte sur un vêtement dont l'étoffe extérieure est faite à partir d'un tissu multifilaments à armure toile dérivé de fils d'aramide, de polyimide, de polyamide ou de polybenzimidazole. La feuille interne est un matériel tissé, non tissé ou tricoté. Les deux feuilles sont laminées au moyen d'un adhésif de telle manière qu'elles ne glissent pas l'une par rapport à l'autre. Toutefois, l'adhésif permet au laminé d'avoir une perméabilité à l'air d'au moins dix (10) pieds cubes-minute lorsque testé selon ASTM D737.
