Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a stiff, cotton-like micro-elastic air layer. Background Technology

[0002] Air-layer fabrics primarily serve a warming function. Through structural design, they employ a three-layer fabric structure—inner, middle, and outer—creating an air gap within the fabric to achieve a warming effect.

[0003] Defects: Current production technologies mainly involve adding polyurethane elastic fiber yarn, but adding spandex elastic fiber yarn to fabrics still presents certain challenges. Furthermore, given the demand for breathability and warmth in fabrics, existing technologies cannot create a fabric that combines the characteristics of both—lightweight and comfortable, with good breathability and a certain degree of thickness.

[0004] To address the aforementioned deficiencies, existing technology (Chinese patent application number: 202220387203.0, application date: 2022-02-24) discloses a cotton-like elastic air-layer fabric. Utilizing a spandex air-layer design, the fabric exhibits excellent breathability and elasticity, while the intermediate air-layer design provides excellent warmth. Combined with a cotton-like outer layer, it offers a pleasant cotton-like feel, is lightweight, and highly elastic. The base inner layer provides the necessary fabric support structure and excellent flame-retardant properties.

[0005] Existing technology utilizes the design of spandex air layers to give the fabric good breathability and elasticity. However, the air layers are mostly hollow, which makes the air layer fabric lack a sense of thickness, resulting in poor elasticity and support, and thus greatly reducing comfort.

[0006] Therefore, we proposed that a stiff, cotton-like micro-elastic air layer can effectively solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a stiff, cotton-like, slightly elastic air layer to solve the problem that the air layers mentioned in the background art are mostly hollow, which makes the air layer fabric lack a sense of thickness, resulting in poor elasticity and support, and thus greatly reducing comfort.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stiff, cotton-like micro-elastic air layer, comprising an inner base layer, an antibacterial layer heat-sealed to the upper surface of the inner base layer, and a knitted inner layer disposed on the side of the antibacterial layer away from the inner base layer, and an intermediate air layer heat-sealed to the side of the knitted inner layer away from the antibacterial layer.

[0009] A cotton-like outer layer is heat-sealed above the intermediate air layer, and an elastic ball and a limiting band are connected inside the knitted inner layer. The upper surface of the cotton-like outer layer is connected with warp yarns and weft yarns respectively.

[0010] Preferably, the limiting band is composed of multiple arcs, and multiple elastic balls are embedded inside the limiting band. The elastic balls are made of spandex, and the limiting band is made of elastic cotton.

[0011] Preferably, the interior of the intermediate air layer is provided with a moisture-guiding rod and a connecting block, and the two ends of the moisture-guiding rod are in contact with the bottom of the imitation cotton surface layer and the top of the antibacterial layer, respectively.

[0012] Preferably, the moisture-guiding rods are evenly distributed inside the intermediate air layer, and the moisture-guiding rods are cylindrical in shape.

[0013] Preferably, every two connecting blocks are arranged in an "X" shape between two moisture-guiding rods, and the moisture-guiding rods are made of hemp fiber material.

[0014] Preferably, the lower surface of the inner base layer is provided with equally spaced ventilation grooves, and the ventilation grooves are arranged in a long strip structure.

[0015] Preferably, the warp and weft yarns are distributed at equal intervals inside the cotton-like surface layer according to an interlacing pattern, wherein the warp yarns are made of nylon fibers and the weft yarns are made of aramid fibers.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the stiff, cotton-like micro-elastic air layer adopts a novel structural design, the specific details of which are as follows:

[0017] (1) The set limiting band can stably limit the elastic ball, so that the elastic ball can be evenly and stably distributed in the knitted inner layer. At the same time, the set elastic ball makes the air layer fabric have good elasticity and soft comfort. The two air layers formed by the knitted inner layer and the middle air layer make the fabric have sufficient thickness and lightness.

[0018] (2) By setting a cotton-like surface layer, the air layer fabric has a good cotton-like feel, and the antibacterial layer can effectively inhibit the growth of bacteria.

[0019] (3) The warp and weft yarns are interwoven in the interior of the imitation cotton surface according to the interlacing pattern and form a mesh, which makes the air layer fabric have high toughness and strength, and at the same time has flame retardant properties.

[0020] (4) The moisture-wicking rod can absorb sweat and evaporate and release moisture quickly. Combined with the breathable layer, it can effectively improve the breathability of the surface. Attached Figure Description

[0029] Please see Figures 1-6 The present invention provides the following technical solution: a stiff, cotton-like micro-elastic air layer;

[0030] Example 1: To address the problem that existing technologies often employ hollow designs for air layers, resulting in a lack of thickness in the air layer fabric, poor elasticity and support, and consequently, significantly reduced comfort, the following solution is disclosed. Please refer to the following for details. Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, it includes an inner base layer 1, an antibacterial layer 3 is heat-sealed to the upper surface of the inner base layer 1, and a knitted inner layer 4 is provided on the side of the antibacterial layer 3 away from the inner base layer 1, and an intermediate air layer 5 is heat-sealed to the side of the knitted inner layer 4 away from the antibacterial layer 3.

[0031] The upper part of the intermediate air layer 5 is heat-sealed with a cotton-like outer layer 6. The inner part of the knitted inner layer 4 is connected with elastic balls 9 and a limiting band 10. The limiting band 10 is composed of multiple arcs. Multiple elastic balls 9 are embedded in the inner side of the limiting band 10. The elastic balls 9 are made of spandex material, and the limiting band 10 is made of elastic cotton material.

[0032] The limiting band 10 can stably limit the elastic ball 9, so that the elastic ball 9 can be evenly and stably distributed in the knitted inner layer 4. At the same time, the elastic ball 9 makes the air layer fabric elastic and soft and comfortable. The two air layers formed by the knitted inner layer 4 and the middle air layer 5 make the fabric thick enough yet lightweight. The cotton-like outer layer 6 makes the air layer fabric have a good cotton-like feel. Meanwhile, the antibacterial layer 3 can effectively inhibit the growth of bacteria.

[0033] Example 2: Unlike Example 1, this example utilizes the moisture-wicking rod 11 and the breathable groove 2 to effectively improve the breathability of the fabric. See details... Figure 1 , Figure 4 and Figure 6 As shown, the lower surface of the inner base layer 1 is provided with equally spaced air grooves 2, and the air grooves 2 are arranged in a long strip structure. The interior of the middle air layer 5 is provided with moisture-guiding rods 11 and connecting blocks 12, and the two ends of the moisture-guiding rods 11 are in contact with the bottom of the imitation cotton surface layer 6 and the top of the antibacterial layer 3, respectively. The moisture-guiding rods 11 are evenly distributed in the interior of the middle air layer 5, and the moisture-guiding rods 11 are arranged in a cylindrical shape. Every two connecting blocks 12 are arranged in an "X" shape between the two moisture-guiding rods 11. The moisture-guiding rods 11 are made of hemp fiber material.

[0034] The connecting block 12 can improve the stability of the moisture-wicking rod 11. At the same time, the moisture-wicking rod 11 can absorb sweat and evaporate and release moisture quickly. Combined with the setting of the breathable groove 2, it can effectively improve the breathability of the fabric.

[0035] Example 3: Unlike Example 2, this example utilizes the warp yarns 7 and weft yarns 8 to improve the toughness and strength of the air layer fabric. See details... Figure 1 and Figure 2 As shown, the upper surface of the imitation cotton surface layer 6 is connected with warp yarns 7 and weft yarns 8 respectively. The warp yarns 7 and weft yarns 8 are distributed at equal intervals inside the imitation cotton surface layer 6 according to the interlacing pattern. The warp yarns 7 are made of nylon fiber and the weft yarns 8 are made of aramid fiber.

[0036] Warp yarns 7 and weft yarns 8 are interwoven in the interior of the cotton-like surface layer 6 according to the interlacing pattern, forming a mesh, which gives the air layer fabric high toughness and strength, as well as flame retardant properties.
