The partition belt 30 is arranged between the first fabric layer 10 and the second fabric layer 20, so that the filling cavity 40 enclosed by the first fabric layer 10 and the second fabric layer 20 is more three-dimensional compared with the filling cavity (shown by referring to fig. 1) of a quilting structure in the prior art, the hollow area or the thin velvet area at the quilting position is eliminated, heat is prevented from being quickly dissipated outwards through the area, meanwhile, the filling quantity of the filling cavity is increased, more thermal insulation filler can be filled, and the thermal insulation property of the fabric structure can be further improved. The partition strip 30 may further be provided to be flexible so as to be capable of being connected to the first and/or second facer layers 10, 20 at variable angles, and to be correspondingly inclined in response to movement or activity of the first and/or second facer layers 10, 20, maintaining the flatness and comfort of the fabric structure. The partition tape 30 and the second fabric layer 20 and/or the first fabric layer 10 are/is a one-piece fabric structure, which means that all structures are integrally formed by one piece of fabric, and are opposite to another mode of cutting the same kind or various kinds of fabrics/materials to make various pieces of parts in advance and then splicing the pieces of parts. The partition belt 30 and the second fabric layer 20 and/or the first fabric layer 10 are/is arranged to be of a one-piece fabric structure, so that the fabric can be used to the maximum degree due to the material manufacturing, and various complex fabrics or other materials are not needed to be spliced, so that the complexity is removed, and the cutting is reduced; but also can maintain high integral uniformity and improve aesthetic feeling. Specifically, referring to fig. 5, the partition tape 30 is formed by folding the one-piece fabric over a portion of a predetermined area (above it). Thus, the folding partition tape 30 can be formed by a simple stacking operation, and is simple, convenient and easy to operate. Referring to fig. 2, the filling chamber 40 may be further filled with a movable thermal insulation filler. The thermal insulation filler comprises one or more of down, silk, wool, chemical fiber and foaming particles, is filled in the filling cavity 40 and can move in the filling cavity 40, gaps among the filling fillers are provided with a certain amount of air, and due to small gaps, air convection between the filling fillers is poor, so that cold air outside cannot easily reach the inside, and hot air inside cannot easily reach the outside. So that the temperature is maintained. The heat preservation principle of the existing heat preservation products such as down jackets and the like is adopted.
In one embodiment, as described with reference to fig. 3, the partition belt 30 and the second fabric layer 20 are of a one-piece fabric structure, and the second fabric layer 20 is disposed on the inner side of the first fabric layer 10, and in this case, the second fabric layer 20 is an inner layer, the first fabric layer 10 is a surface layer, and the partition belt 30 and the inner layer are of a one-piece fabric structure. In other embodiments, the partition belt 30 may be of a one-piece fabric construction with the facing layer, or the facing layer, the inner layer, and the partition belt may all be of a one-piece fabric construction.
Referring to fig. 2 and 6, the partition tape 30 includes a folded edge 301, and a first folded sheet 302 and a second folded sheet 303 overlapped along the folded edge 301, the folded edge 301 is connected to the first fabric layer 10, one end of the first folded sheet 302 away from the folded edge 301 and one end of the second folded sheet 302 away from the folded edge 301 are connected to form a connection end 304, the connection end 304 is integrally connected to the second fabric layer 20, and the connection end 304 is a common edge of the partition tape 30 and the second fabric layer 20. More specifically, the fold 301 is bonded or sewn to the first facestock layer 10. The end of the first folded sheet 302 remote from the folded edge 301 and the end of the second folded sheet 303 remote from the folded edge 301 are also bonded or sewn to form a connecting end 304 (as shown in fig. 3 and 5, the sides of the ends of the first folded sheet 302 and the second folded sheet 303 remote from the folded edge 301 are connected to form the connecting end 304). The bonding can realize the traceless wireless trace of the exposed surface of the fabric structure, so that the fabric structure has more integrity and is highly concise and uniform.
In a specific embodiment, the folded edge 301 is connected to the first fabric layer 10 by means of a seam, which seam forms a first connecting seam, and the end of the first folded sheet 302 remote from the folded edge 301 and the end of the second folded sheet 303 remote from the folded edge 301 are seam forming a second connecting seam, which first connecting seam and second connecting seam penetrate through the first fabric layer 10 and the second fabric layer 20, respectively. The seam is thus visible on both outer sides of the thermal fabric structure (the sides of the first and second panels 10, 20 facing away from each other), and the quilting visual effect is still visible on the outer sides, as shown in fig. 7.
The invention also provides a thermal insulation product with the thermal insulation fabric structure, wherein the thermal insulation product is a garment, a quilt, a pillow, a cushion or a sleeping bag, and the filling cavity is filled with thermal insulation filler. When the thermal insulation filler is not filled, the thermal insulation filler can also be in the outer cover structures such as a quilt cover, a pillowcase and the like.
In one embodiment, the thermal article is a thermal garment, and the width of the partition tape 30 is 1.0-2.5cm, the width direction being the direction from the first facer layer 10 to the second facer layer 20 or the second facer layer 20 to the first facer layer 10.

Fig. 7 illustrates a down jacket manufactured by the thermal fabric structure and method provided by the invention, wherein the left side is the down jacket manufactured by the thermal fabric structure and method provided by the invention, and the right side is the conventional quilting type down jacket.
Referring to fig. 8, by comparing the thermal test of the down jacket (new process is shown in the figure) provided by the present invention with the conventional quilted structure down jacket (old process is shown in the figure) mentioned in the background art, it was observed that the surface temperatures of the two garments gradually increased during the test. The temperatures at the armpit and zipper showed a significant change in both garments 10 minutes after the start of the test. At the needle-car position on the front of the garment, the temperature rise of the old art garment (the traditional quilting structure down jacket) begins to appear, while the new art garment (the warm-keeping fabric structure down jacket provided by the invention) shows relatively stability and no obvious change. As the test proceeds, the zipper and underarm temperatures of the new art garment continue to rise for 20 minutes, with some temperature change occurring in the abdomen and underarm needle bed areas. In contrast, older art garments have significantly warmed up the neckline, sleeves, and needle bed areas on the front of the garment 20 minutes after the start of the test. Overall, the new art garment exhibits better warmth retention throughout the test process from the thermodynamic distribution data. The thermal distribution diagram and the garment surface temperature data show that the novel process garment can better prevent heat conduction at the needle car position, thereby having better heat insulation effect and showing better heat insulation performance.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that; the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
