Flame resistant and chemical protective textile material

A treated textile material comprising:

• (a) a textile substrate having a first surface, the textile substrate comprising a plurality of first yarns and a plurality of second yarns, the plurality of first yarns being disposed in a first direction in the textile substrate, the plurality of second yarns being disposed in a second direction perpendicular to the first direction, the plurality of first yarns and the plurality of second yarns being interwoven, the first yarns and second yarns each comprising about 90 wt. % or more of inherent flame resistant staple fibers, the textile substrate having an areal density of about 150 g/m2 or more and an optical transparency of about 10% or less;
• and
• (b) a finish disposed on the first yarns and the second yarns, the finish comprising a fluorochemical repellent, the fluorochemical repellent being present on the textile material in an amount of about 0.05 grams or more of fluorochemical repellent per gram of the textile substrate,
• wherein the treated textile material exhibits an air permeability of about 1,400 l/min or more.
