An improved insulating performance fabric has a double-knit body, formed with traditional, relatively smooth, outer surfaces, and an inner surface with the form of multiple fabric “bubbles” separated, e.g., by a grid pattern of intersecting grooves. An insulating, double-knit performance fabric of this disclosure may also be found in the form of a garment comprising the insulating, double knit performance fabric, or in the form of fabric article comprising the insulating, double knit performance fabric, etc.

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 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 contain a plurality of rows of multi-filament fibers extending parallel to at least one of the first and second knit layers.

The invention related to an insulating, double-knit fabric having a width and a length and comprising a first knit layer and a second knit layer coupled with the first knit layer forming a plurality of rows of lofted fibers separated by rows of air spaces. The air spaces extend along the length of the insulating, double-knit fabric for the entire length of the fabric and the lofted fibers extend in a direction having an orthogonal component with respect to the at least one of the first knit layer and the second knit layer.

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.

The invention related to an insulating, double-knit fabric comprising an outer knit layer and an inner knit layer coupled with the outer knit layer forming a plurality of elongated air pockets in a plurality of rows. Only the outer layer comprises a plurality of windows, where the air pockets comprise intermediate fiber regions and the intermediate fiber regions comprise fibers positioned parallel to the inner and outer knit layers.
