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 relates generally to a method for combining multiple knit constructions in a single fabric using a double selection circular knitting machine. It is in particular directed of seamlessly combining in a single fabric an air circulating construction with a double-knit construction. It further provides a fabric obtained using the method of the present invention.

A footwear upper is made of a knitted engineered fabric. The footwear upper includes a front portion for covering an upper part of a foot, an intermediate portion corresponding to an insole, and a rear portion for covering a heel. The front portion, the intermediate portion and the rear portion are produced with an engineered fabric composed of an internal core and a pair of external layers of knitted fabric. The footwear upper is made as one piece, is already contoured during a machining stage and is ready to be applied to a sole without any other type of machining, except for the possibility of sealing for joining the front portion to the rear portion laterally.

Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material comprising including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

A footwear upper made of a knitted engineered fabric. The upper includes a front portion (2) for covering the upper part of the foot, an intermediate portion (3) corresponding to the insole, and a rear portion (4) for covering the heel. The front (2), intermediate (3) and rear (4) portions are produced with an engineered fabric composed of an internal core (5) and a pair of external layers (6 and 7) of knitted fabric. The upper is made as one piece and already contoured during the machining stage and is ready to be applied to the sole without any other type of machining, except for the possibility of sealing for joining the first portion to the third laterally. Due to the different types of machining of the engineered fabric with which it is made, the upper acquires structural features which are transformed into functional features for footwear.

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.
