Technical Field

[0001] This utility model belongs to the field of infant and toddler products technology, and in particular relates to a composite wadding and sleeping bag. Background Technology

[0002] Infants and toddlers are active sleepers, often kicking off their blankets and adopting various sleeping positions. Because their bodies have weak temperature regulation abilities, they are easily chilled. Therefore, they are often placed in soft, warm sleeping bags to ensure their comfort and health. Currently, infant sleeping bags prioritize warmth. Traditional sleeping bags use wadding that only provides basic temperature control and warmth, often resulting in drawbacks such as bulkiness, poor moisture absorption, insufficient breathability, potential allergies, and durability issues.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a composite flocculent sheet, including a first layer structure and a second layer structure disposed on one side of the first layer structure. Both the first layer structure and the second layer structure include multiple stacked flocculent sheets, and the weights of the first layer structure and the second layer structure are different.

[0005] Furthermore, the weight of the first layer is less than the weight of the second layer.

[0006] Furthermore, the weight ratio of the first layer to the second layer is 1:2.2-1:5.5.

[0007] Furthermore, the materials of the first layer are different from those of the second layer.

[0008] Furthermore, the first layer is made of hollow down-like microfiber, and the second layer is made of windmill-shaped cross-section fiber.

[0013] A sleeping bag includes an outer layer, an inner layer, and a composite wadding as described above disposed between the outer and inner layers, wherein the first layer is attached to the outer layer and the third layer is attached to the inner layer.

[0014] Due to the adoption of the above technical solution, the composite wadding has a layered structure, including a first layer and a second layer. Both the first and second layers consist of multiple sheets, and their weights and materials are different. The first layer is attached to the outer layer of the sleeping bag, and the second layer is attached to the inner layer.

[0019] 10. Layers Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Figure 1The diagram shows a structural schematic of an embodiment of the present invention. This embodiment relates to a composite wadding and a sleeping bag. The composite wadding is disposed in the inner and outer layers of the sleeping bag. The composite wadding has a layered structure, which can simultaneously achieve the dual functions of efficient heat preservation and moisture wicking, making the composite wadding thinner and lighter, and giving the composite wadding good breathability and moisture permeability.

[0022] Example 1

[0023] A type of composite flocculent, such as Figure 1 As shown, the composite sheet includes a first layer structure 1 and a second layer structure 2 disposed on one side of the first layer structure 1. Both the first layer structure 1 and the second layer structure 2 include multiple stacked sheets 10, that is, the composite sheet is a layered structure, including the first layer structure 1 and the second layer structure 2. The second layer structure 2 is laid on one side of the first layer structure 1, for example, along the vertical direction, the second layer structure 2 is laid on the first layer structure 1. The second layer structure 2 and the first layer structure 1 are arranged vertically. Both the first layer structure 1 and the second layer structure 2 have a certain area and thickness. The sheet-like structure is composed of fibers. Both the first layer structure 1 and the second layer structure 2 include multiple sheets 10. The multiple sheets 10 are stacked. The second sheet 10 is laid on the first sheet 10, the third sheet 10 is laid on the second sheet 10, the fourth sheet 10 is laid on the third sheet 10, the fifth sheet 10 is laid on the fourth sheet 10, and so on. The multiple sheets 10 are stacked sequentially from bottom to top to form a layer structure. The multiple layer structures are stacked sequentially to form a composite flocculent structure.

[0024] Both the first layer structure 1 and the second layer structure 2 are made of fibers. Therefore, the multiple sheets 10 that make up the first layer structure 1 and the second layer structure 2 are also made of fibers. For any sheet 10, the formation process is to lay fibers evenly along the left and right direction. When the fibers are laid, the thickness is uniform at each position, so that each sheet 10 is a sheet structure with uniform thickness of fiber.

[0025] The materials of the first layer (structure 1) and the second layer (structure 2) are different. The first layer (structure 1), which is closer to the outer layer of the sleeping bag, is made of hollow, down-like microfiber. This hollow structure allows for maximum retention of still air, achieving excellent warmth retention. The second layer (structure 2), which is closer to the inner layer of the sleeping bag, is made of windmill-shaped cross-section fibers. The irregular cross-section increases the surface texture of the fibers, facilitating rapid moisture conduction and thus providing excellent moisture absorption. Due to the different functions of the first and second layers (structure 1 and structure 2), the composite quilt has the dual functions of warmth retention, heat locking, and breathability and moisture wicking. This makes the composite quilt lightweight and also gives it excellent breathability and moisture permeability, enhancing its breathability, moisture wicking, and perspiration-wicking capabilities.

[0026] In the first layer structure 1, the weight of each layer 10 is the same. In the second layer structure 2, the weight of each layer 10 is the same. That is, the weight of each layer 10 in the first layer structure 1 is the same. For example, if the weight of the first layer structure 1 is n1, then the weight of each layer 10 in the first layer structure 1 is 1 / n1. The weight of each layer 10 in the second layer structure 2 is the same. For example, if the weight of the second layer structure 2 is n2, then the weight of each layer 10 in the second layer structure 2 is 1 / n2.

[0027] The first layer structure 1 and the second layer structure 2 have different weights. Therefore, the weight of each sheet 10 in the first layer structure 1 is different from the weight of each sheet 10 in the second layer structure 2, and the thickness of the first layer structure 1 is also different from the thickness of the second layer structure 2. In some feasible embodiments, the weight of the first layer structure 1 is less than the weight of the second layer structure 2, the weight of each sheet 10 in the first layer structure 1 is less than the weight of each sheet 10 in the second layer structure 2, and the thickness of each sheet 10 in the first layer structure 1 is less than the thickness of each sheet 10 in the second layer structure 2.

[0028] In some feasible embodiments, the weight ratio of the first layer structure 1 to the second layer structure 2 is 1:2.2-1:5.5. This weight ratio can be any value between 1:2.2 and 1:5.5, such as 1:2.2, 1:3, 1:3.5, 1:4, 1:4.5, 1:5, or 1:5.5. The weight ratio of the first layer structure 1 to the second layer structure 2 is selected according to actual needs, and no specific requirements are specified here. Controlling the weight ratio of the first layer structure 1 to the second layer structure 2 to be between 1:2.2 and 1:5.5 ensures good insulation performance of the composite wadding while maintaining a moderate weight, resulting in a comfortable sleeping bag. If the weight ratio is less than 1:2.2, the insulation performance of the composite wadding is poor. If the weight ratio is greater than 1:5.5, the overall weight of the composite wadding increases, leading to a poor sleeping experience. The weight ratio of the first layer structure 1 to the second layer structure 2 is 1:2.2-1:5.5, so that the heat preservation rate of the composite wadding is maintained at 80%-85% and the air permeability is within the range of 800-1400mm / s.

[0029] In some feasible embodiments, the weight ratio of the first layer structure 1 to the second layer structure 2 is 1:3. For example, if the total weight of the composite wadding is 160g, then the weight of the first layer structure 1 is 40g, and the first layer structure 1 includes three sheets 10, each weighing 13.3g. The weight of the second layer structure 2 is 120g, and the second layer structure 2 includes eight sheets 10, each weighing 15g. The composite wadding of this weight maintains a thermal insulation rate of over 83% and an air permeability within the range of 800-1400mm / s.

[0030] In some feasible embodiments, the weight ratio of the first layer structure 1 to the second layer structure 2 is 1:4. For example, if the total weight of the composite wadding is 150g, then the weight of the first layer structure 1 is 30g, and the first layer structure 1 includes three sheets 10, each weighing 10g. The weight of the second layer structure 2 is 120g, and the second layer structure 2 includes eight sheets 10, each weighing 15g. The thermal insulation rate of this weight of composite wadding is not less than 81%, and the air permeability is still within the range of 800-1400mm / s.

[0031] In some feasible embodiments, the weight ratio of the first layer structure 1 to the second layer structure 2 is 1:5. For example, if the total weight of the composite wadding is 180g, then the weight of the first layer structure 1 is 30g, and the first layer structure 1 includes three sheets 10, each weighing 10g. The weight of the second layer structure 2 is 150g, and the second layer structure 2 includes eight sheets 10, each weighing 18.75g. The composite wadding of this weight has a thermal insulation rate of not less than 80% and an air permeability in the range of 800-1400mm / s.

[0032] A sleeping bag includes an outer layer, an inner layer, and a composite wadding as described above disposed between the outer and inner layers. The first layer structure 1 is attached to the outer layer and can retain still air to the maximum extent to achieve good warmth retention. The second layer structure 2 is attached to the inner layer and can conduct moisture quickly, having good moisture absorption function. This makes the sleeping bag with the composite wadding have the dual functions of warmth retention, heat retention, breathability, and moisture wicking, making the sleeping bag lightweight and having good breathability and moisture permeability, with better breathability, moisture wicking, and perspiration wicking effects.

[0033] Example 2

[0034] Compared with Example 1, in this embodiment, as follows: Figure 2As shown, the composite wadding has a three-layer structure. In addition to the first layer structure 1 and the second layer structure 2, the composite wadding also includes a third layer structure 3. The third layer structure 3 is located on the other side of the second layer structure 2, that is, the second layer structure 2 is located between the first layer structure 1 and the third layer structure 3. The third layer structure 3 includes multiple stacked sheets 10. The third layer structure 3 has the same weight as the first layer structure 1. The number of sheets 10 in the first layer structure 1 is the same as the number of sheets 10 in the third layer structure 3. Moreover, the material of the third layer structure 3 is the same as the material of the first layer structure 1. The material of the third layer structure 3 is a hollow down-like microfiber.

[0035] In some feasible embodiments, the weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 is 1:2.2:1 to 1:5.5:1. The weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 can be any weight ratio value between 1:2.2:1 and 1:5.5:1, such as 1:2.2:1, 1:3:1, 1:3.3:1, 1:4:1, 1:4.5:1, 1:5:1, and 1:5.5:1. The weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 is selected according to actual needs, and no specific requirements are made here. The weight ratio of the first layer (structure 1), the second layer (structure 2), and the third layer (structure 3) is controlled within the range of 1:2.2:1 to 1:5.5:1. This ensures good insulation of the composite wadding while maintaining a moderate weight, resulting in a comfortable sleeping bag. If the weight ratio is less than 1:2.2:1, the insulation effect of the composite wadding will be poor. If the ratio is greater than 1:5.5:1, the overall weight of the composite wadding will increase, leading to a poor sleeping experience. Using a weight ratio of 1:2.2:1 to 1:5.5:1 for the first layer (structure 1) maintains an insulation rate of 80%-85% and an air permeability within the range of 800-1400 mm / s.

[0036] In some feasible embodiments, the weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 is 1:3.3:1. For example, if the total weight of the composite wadding is 160g, then the weight of the first layer structure 1 is 30g, and the first layer structure 1 includes three sheets 10, each sheet 10 weighing 10g. The weight of the second layer structure 2 is 100g, and the second layer structure 2 includes eight sheets 10, each sheet 10 weighing 12.5g. The weight of the third layer structure 3 is 30g, and the third layer structure 3 includes three sheets 10, each sheet 10 weighing 10g. The composite wadding of this weight maintains a heat retention rate of over 82% and an air permeability within the range of 800-1400mm / s.

[0037] In some feasible embodiments, the weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 is 1:4:1. For example, if the total weight of the composite wadding is 120g, then the weight of the first layer structure 1 is 20g, and the first layer structure 1 includes two sheets 10, each weighing 10g. The weight of the second layer structure 2 is 80g, and the second layer structure 2 includes eight sheets 10, each weighing 10g. The weight of the third layer structure 3 is 20g, and the third layer structure 3 includes two sheets 10, each weighing 10g. The thermal insulation rate of this weight of composite wadding is not less than 81%, and the air permeability can still be maintained within the range of 800-1400mm / s.

[0038] In some feasible embodiments, the weight ratio of the first layer structure 1, the second layer structure 2, and the third layer structure 3 is 1:5:1. For example, if the total weight of the composite wadding is 210g, then the weight of the first layer structure 1 is 30g, and the first layer structure 1 includes three sheets 10, each weighing 10g. The weight of the second layer structure 2 is 150g, and the second layer structure 2 includes eight sheets 10, each weighing 18.75g. The weight of the third layer structure 3 is 30g, and the third layer structure 3 includes three sheets 10, each weighing 10g. The composite wadding of this weight has a heat retention rate of not less than 80% and an air permeability in the range of 800-1400mm / s.

[0039] In the third layer structure 3, the weight of each layer 10 is the same. For example, the weight of the third layer structure 3 is n1, and the weight of each layer 10 in the third layer structure 3 is 1 / n1.

[0040] A sleeping bag includes an outer layer, an inner layer, and a composite wadding as described above disposed between the outer and inner layers. The first layer structure 1 is attached to the outer layer, the third layer structure 3 is attached to the inner layer, and the second layer structure 2 is located between the first layer structure 1 and the third layer structure 3. Both the first layer structure 1 and the third layer structure 3 can retain still air to the maximum extent to achieve good warmth retention. The second layer structure 2 can conduct moisture quickly and has good moisture absorption function. This makes the sleeping bag with the composite wadding have the dual functions of warmth retention, heat locking, breathability, and moisture wicking. This makes the sleeping bag lightweight and has good breathability and moisture permeability, with better breathability, moisture wicking, and perspiration wicking effects.

[0041] Due to the adoption of the above technical solution, the composite wadding has a layered structure, including a first layer and a second layer. Both the first and second layers consist of multiple sheets, and their weights and materials are different. The first layer is attached to the outer layer of the sleeping bag, and the second layer is attached to the inner layer. Alternatively, the composite wadding includes a first layer, a second layer, and a third layer, with the first and third layers respectively positioned on either side of the second layer. The first and third layers have the same weight, and the first and third layers are... The layers are made of the same material. The first layer is close to the outer layer of the sleeping bag, and the third layer is close to the inner layer. Both the first and third layers are made of hollow down-like microfiber, which can retain still air and achieve warmth. The second layer is made of windmill-shaped cross-section fiber, which can conduct moisture and has a moisture-absorbing function. This allows the composite quilt to achieve both efficient warmth retention and breathability and moisture wicking. The composite quilt is lightweight while maintaining warmth, improving breathability and moisture wicking.

[0042] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
