[0002] Fabric is the material used to make clothing. Warm fabric is a type of fabric. Compared with other fabrics, it has more outstanding warmth retention performance and can be easily used to make winter clothing with good warmth retention.
[0003] Existing thermal insulation fabrics typically improve their warmth by increasing the fabric's thickness. However, while thicker fabrics ensure warmth, the resulting garments are also heavier, failing to adequately improve user comfort and potentially causing inconvenience.
[0004] Therefore, those skilled in the art have provided a composite thermal insulation fabric to solve the problems mentioned in the background art. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art and provide a composite thermal insulation fabric.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a composite thermal insulation fabric, comprising a waterproof and breathable layer, wherein the waterproof and breathable layer is hollow, and a cross-shaped dividing line is provided on the outer wall of the waterproof and breathable layer, the cross-shaped dividing line dividing the cavity of the waterproof and breathable layer into individual squares, the cavity of the waterproof and breathable layer is filled with down, a high-tech thermal insulation layer is provided on the side of the waterproof and breathable layer closest to the skin, an infrared thermal insulation layer is provided on one side of the high-tech thermal insulation layer, and an inner lining layer is composited on one side of the infrared thermal insulation layer, and the longitudinal sections of the high-tech thermal insulation layer, the infrared thermal insulation layer and the inner lining layer are interspersed with equally spaced warp threads.
[0007] Preferably, the waterproof and breathable layer is made of polytetrafluoroethylene, with one billion micropores per square centimeter. Down is evenly filled into each square cavity, and cross-shaped dividing lines connect the inner side of the waterproof and breathable layer to the high-tech insulation layer.
[0008] Preferably, the high-tech insulation layer is made of 3D-printed aerogel cotton.
[0009] Preferably, the infrared insulation layer comprises fiber filaments, far-infrared ceramic powder, dispersant, and binder. The far-infrared ceramic powder is uniformly coated onto the fiber filaments by the dispersant and binder, and the fiber filaments are woven into a fiber cloth.
[0010] Preferably, the inner lining layer is made of cotton fabric.
[0011] Preferably, the warp is divided into two sections, with one section interspersed between the high-tech insulation layer and the infrared insulation layer, and another section interspersed between the infrared insulation layer and the inner lining layer, and the two sections are staggered.
[0012] Preferably, the inner lining layer has an additional layer on the side closest to the skin. The additional layer includes fox fur, and Velcro is sewn and fixed to one side of the fox fur and the outer wall of the inner lining layer. The fox fur is fixed to the inner lining layer by the Velcro.
[0013] This invention provides a composite thermal insulation fabric. It has the following beneficial effects:
[0014] (1) This composite thermal insulation fabric has a waterproof and breathable layer on the outermost side. The waterproof and breathable layer is made of polytetrafluoroethylene. The waterproof and breathable layer has one billion micropores per square centimeter, which can block water droplets but allow water vapor to pass through. The micropores are irregularly arranged, which has good waterproof and windproof performance. The cross dividing lines are set to divide the down cavity into squares and fill it with down, which improves the thermal insulation performance of the fabric. The high-tech thermal insulation layer and infrared thermal insulation layer are set to further improve the thermal insulation performance of the fabric. The high-tech thermal insulation layer, infrared thermal insulation layer and inner lining layer are fixed together by warp threads, and the fabric is composited into one, which is lightweight and has good thermal insulation performance.
[0015] (2) The high-tech insulation layer uses 3D printed aerogel cotton. 3D printed aerogel cotton has a low thermal conductivity and is extremely lightweight, which can improve the insulation performance of the fabric. Far-infrared ceramic powder is evenly coated on the fiber filaments with a dispersant and adhesive, and then the treated fiber filaments are woven into fiber cloth. When the human body emits heat, this heat is radiated outward in the form of far-infrared rays. The infrared insulation layer can absorb, reflect or re-radiate these far-infrared rays, resonate with the human body's own heat, thereby effectively locking in the heat emitted by the body, reducing heat loss, and achieving the effect of keeping warm.
[0016] (3) By setting the material of the inner lining to cotton, which has good breathability, when it is necessary to go to an extremely cold area, the fox fur can be attached to the inner lining with Velcro to further improve the warmth performance of the fabric. Attached Figure Description

[0023] like Figure 1-4 As shown: A composite thermal insulation fabric includes a waterproof and breathable layer 10, which is hollow. A cross-shaped dividing line 15 is provided on the outer wall of the waterproof and breathable layer 10, dividing the cavity of the waterproof and breathable layer 10 into individual squares. Down 14 is filled into the cavity of the waterproof and breathable layer 10. A high-tech thermal insulation layer 11 is provided on the side of the waterproof and breathable layer 10 closest to the skin. An infrared thermal insulation layer 12 is provided on one side of the high-tech thermal insulation layer 11. An inner lining layer 13 is composited on one side of the infrared thermal insulation layer 12. Warp threads 16 are interspersed at equal intervals along the longitudinal section of the high-tech thermal insulation layer 11, the infrared thermal insulation layer 12, and the inner lining layer 13. The waterproof and breathable layer 10 is made of polytetrafluoroethylene (PTFE) and has one billion micropores per square centimeter. The down 14 is evenly filled into the individual square cavities. The cross-shaped dividing line 15 also connects the inner side of the waterproof and breathable layer 10 to the high-tech thermal insulation layer 11.
[0024] Specifically, this composite thermal insulation fabric features a waterproof and breathable layer 10 on the outermost side. The waterproof and breathable layer 10 is made of polytetrafluoroethylene and has one billion micropores per square centimeter, which can block water droplets while allowing water vapor to pass through. The micropores are irregularly arranged, providing good waterproof and windproof performance. Cross-shaped dividing lines 15 divide the cavity of the down 14 into individual squares and fill it with down 14, improving the fabric's thermal insulation performance. The high-tech thermal insulation layer 11 and infrared thermal insulation layer 12 further enhance the fabric's thermal insulation performance. The high-tech thermal insulation layer 11, infrared thermal insulation layer 12, and inner lining layer 13 are fixed together by warp threads 16, making the fabric a single, lightweight, and highly insulating unit.
[0025] The high-tech insulation layer 11 is made of 3D-printed aerogel cotton.
[0026] Specifically, the high-tech insulation layer 11 uses 3D-printed aerogel cotton, which has a low thermal conductivity and is extremely lightweight, thus improving the insulation performance of the fabric.
[0027] The infrared insulation layer 12 is composed of fiber filaments, far-infrared ceramic powder, dispersant and adhesive. The far-infrared ceramic powder is evenly coated on the fiber filaments by the dispersant and adhesive and then woven into a fiber cloth by the fiber filaments.
[0028] Specifically, by uniformly coating far-infrared ceramic powder onto fiber filaments with a dispersant and binder, and then weaving the treated fiber filaments into fiber cloth, when the human body emits heat, this heat is radiated outward in the form of far-infrared rays. The infrared insulation layer 12 can absorb, reflect, or re-radiate these far-infrared rays, resonating with the human body's own heat, thereby effectively locking in the heat emitted by the body, reducing heat loss, and achieving a warming effect.
[0029] The inner lining layer 13 is made of cotton fabric. An additional layer is provided on the side of the inner lining layer 13 closest to the skin. The additional layer includes fox fur 18. Velcro 17 is sewn and fixed on one side of the fox fur 18 and the outer wall of the inner lining layer 13. The fox fur 18 is fixed to the inner lining layer 13 by the Velcro 17.
[0030] Specifically, by setting the material of the inner lining layer 13 to cotton, which has good breathability, when it is necessary to go to an extremely cold area, the fox fur 18 can be attached to the inner lining layer 13 through Velcro 17 to further improve the warmth performance of the fabric.
[0031] The meridian 16 is divided into two sections, with one section interspersed between the high-tech insulation layer 11 and the infrared insulation layer 12, and the other section interspersed between the infrared insulation layer 12 and the inner lining layer 13, and the two sections are staggered.
[0032] Specifically, by setting the warp 16 into two sections, a section is interspersed between the high-tech insulation layer 11 and the infrared insulation layer 12, and between the infrared insulation layer 12 and the inner lining layer 13, and the two sections are staggered, resulting in better integrity of the composite fabric.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
