Abstract
An insulating, double-knit fabric containing a first knit layer and a second knit layer coupled with the first knit layer through a plurality of first direction spaced apart rows in a first direction and a plurality of second direction spaced apart rows in a second direction which is perpendicular to the first direction forming a plurality of air pockets in a grid pattern. The fabric also contains a plurality of intermediate fiber regions positioned in the plurality of air pockets, where each of the intermediate fiber regions contains a plurality of rows of multi-filament fibers extending parallel to at least one of the first and second knit layers. The first knit layer and the second knit layer comprise a plurality of flame resistant fibers, a plurality of cellulosic fibers, and a plurality of modacrylic fibers blended together.
