Description

Technical Field

[0001] The invention relates to the technical field of clothing materials, and in particular to a thermal insulation structure and a down jacket. Background Art

[0002] Thermal insulation performance is the primary factor that consumers consider when purchasing down jackets. Traditional down jackets mainly increase the amount of down filling or improve the quality of down to improve thermal insulation performance. However, this will greatly increase material costs, and there is a certain upper limit to the amount of down filling, otherwise it will make the down jacket too bloated, unsuitable for wearing and affect the appearance, so it is necessary to further improve the thermal insulation performance of down jacket lining and outer fabrics.

[0003] There have been attempts in the prior art to improve the thermal insulation effect by setting a coating structure on down jackets to prevent heat radiation. However, simply considering and designing a solution from the perspective of reducing heat radiation cannot take into account other factors such as the breathability and moisture permeability of down jackets. In addition, setting a coating structure over a large area will increase the amount of quilting work and require more manual participation. While the manufacturing cost is high, it also increases the risk of down jackets losing down. Summary of the invention

[0004] The object of the present invention is to provide a thermal insulation structure and a down jacket, which can take into account air permeability, moisture permeability and thermal insulation performance, and has low quilting workload, is not easy to run down, and has low manufacturing cost.

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] like Figure 1-Figure 3As shown, the present invention provides a thermal insulation structure for improving the thermal insulation performance of down jackets. The thermal insulation structure includes a lining 1, a fabric 2, multiple lining insulation layers 4 and multiple fabric insulation layers 5. The lining 1 and the fabric 2 are arranged to form a filling cavity 3, and the filling cavity 3 is filled with thermal insulation materials; multiple lining insulation layers 4 are arranged on the lining 1 at intervals, and the lining insulation layers 4 are in the shape of long strips and extend along the first direction; multiple fabric insulation layers 5 are arranged on the fabric 2 at intervals, and the fabric insulation layers 5 are in the shape of long strips and extend along the first direction. In the second direction, any lining insulation layer 4 is directly opposite to the gap between two adjacent fabric insulation layers 5, and the width of the lining insulation layer 4 in the second direction is not less than the spacing between two adjacent fabric insulation layers 5. Both the lining insulation layer 4 and the fabric insulation layer 5 can reflect the thermal radiation emitted by the human body, and the first direction is perpendicular to the second direction.

[0037] The lining 1 and the outer fabric 2 cooperate with each other so that the thermal insulation material can be filled in the filling cavity 3. Both the lining insulation layer 4 and the outer fabric insulation layer 5 can reflect the thermal radiation emitted by the human body to play a role in thermal insulation. The lining insulation layer 4 and the outer fabric insulation layer 5 cooperate with each other. The double-layer structure can completely cover the outer side of the human body, ensuring air permeability and moisture permeability while having good thermal insulation performance, greatly reducing the loss of human body's own heat, and has a simple structure, low quilting workload, and reduced probability of fleece.

[0038] It should be noted that both the lining thermal insulation layer 4 and the outer material thermal insulation layer 5 are existing technologies disclosed in the art, and their specific principles and detailed structures are not described here in detail.

[0039] Specifically, the thermal insulation structure further includes a plurality of lining heating layers, which are arranged on the side of the lining insulation layer 4 facing the fabric 2, and are configured to absorb light from one side of the fabric 2 and convert it into heat. The arrangement of the lining heating layer can further improve the thermal insulation performance of the thermal insulation structure.

[0040] It should be noted that the above-mentioned lining heating layer is the existing technology disclosed in the art, and its specific principle and detailed structure are not described here.

[0041] More specifically, the lining heating layer corresponds to the lining heat-insulating layer 4. The above arrangement can ensure that the area of ​​the lining heating layer is consistent with the area of ​​the lining heat-insulating layer 4, so as to ensure that the heat-insulating structure has good heat-insulating performance.

[0042] Specifically, in the second direction, the spacing between two adjacent lining insulation layers 4 is greater than the width of the lining insulation layer 4; or, in the second direction, the spacing between two adjacent fabric insulation layers 5 is greater than the width of the fabric insulation layer 5. In the above configuration, when the spacing between two adjacent lining insulation layers 4 is greater than the width of the lining insulation layer 4, correspondingly, when the spacing between two adjacent fabric insulation layers 5 is less than the width of the fabric insulation layer 5, at this time, it is beneficial for the lining 1 to fit the human body, and the experience is better, but some thermal insulation performance will be relatively lost; when the spacing between two adjacent fabric insulation layers 5 is greater than the width of the fabric insulation layer 5, correspondingly, when the spacing between two adjacent lining insulation layers 4 is less than the width of the lining insulation layer 4, at this time, the thermal insulation performance is better, but it is not conducive to the lining 1 fitting the human body, and some wearing comfort will be lost.

[0043] It is understandable that the overall thermal insulation performance and comfort of the garment can be controlled by precisely controlling the spacing between adjacent lining insulation layers 4 and the spacing between two adjacent fabric insulation layers 5 according to design requirements, such as the garment's style, size, expected use environment and other factors.

[0044] Illustratively, in this embodiment, the lining thermal insulation layer 4 is a double-layer structure, and the lining thermal insulation layer 4 is arranged on both sides of the lining 1 in the thickness direction.

[0045] Exemplarily, in this embodiment, the fabric heat-insulating layer 5 is a single-layer structure, and the fabric heat-insulating layer 5 is arranged on the side of the fabric 2 facing the lining 1 .

[0046] Preferably, in this embodiment, the total area of ​​the plurality of lining insulation layers 4 accounts for 40%-70% of the area of ​​the lining 1 to ensure the thermal insulation performance of the thermal insulation structure.

[0047] The present invention also discloses a down jacket, which comprises the above-mentioned heat-insulating structure. It is understandable that the down jacket has all the beneficial effects of the above-mentioned heat-insulating structure, which will not be described in detail here.

[0048] Specifically, in the first direction and / or the second direction, the lining insulation layer 4 and the outer surface insulation layer 5 are both spaced apart. In the above arrangement, when the lining insulation layer 4 and the outer surface insulation layer 5 are both spaced apart in the second direction, Figure 2 When the lining insulation layer 4 and the outer surface insulation layer 5 are both spaced apart in the first direction and the second direction, Figure 3 shown.

[0049] Specifically, the heat-insulating material is down. Exemplarily, in this embodiment, the heat-insulating material can be duck down or goose down commonly used in the art.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
