Description

Technical Field

[0001] This utility model relates to the field of breathable materials for backpacks, and more particularly to a breathable material for backpacks. Background Technology

[0002] Backpacks, as a convenient carrying tool, are widely used in various scenarios such as daily commuting, outdoor travel, sports, and professional work. As consumers continue to improve their requirements for quality of life and user experience, the design of backpacks is no longer limited to basic carrying functions. Comfort, functionality, and especially the breathability of the carrying system have become key indicators for evaluating the quality of products.

[0003] Traditional backpacks typically use a multi-layered composite structure for the back, such as a back panel, foam padding, and inner fabric lining. Heat and sweat generated by the body need to pass through these layers one by one to finally escape. This process is not only slow, but sweat is also easily absorbed by the middle layers, leading to a stuffy feeling. Therefore, a breathable material for backpacks is needed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a breathable material for backpacks, solving the above-mentioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a breathable material for a backpack, comprising a material base layer, the material base layer comprising a covering mesh, a breathable fabric, air holes, and a breathable layer, the breathable layer being covered with a breathable fabric on the outside, the breathable fabric being provided with a covering mesh on the outside, and the covering mesh being connected to the outside of the breathable fabric by sewing.

[0006] The breathable layer is a three-dimensional mesh structure made of one of the following materials: polyethylene elastomer, polypropylene elastomer, polyolefin elastomer, or thermoplastic polyester elastomer. The three-dimensional mesh structure has good ventilation and breathability characteristics.

[0007] Preferably, the three-dimensional mesh structure of the breathable layer has multiple interconnected pores, the pore diameter of which is 0.1 mm to 5 mm.

[0008] Preferably, the outer surface of the breathable fabric is provided with a plurality of air holes.

[0009] Preferably, the outer edge of the material base layer is provided with a seam tape.

[0010] Preferably, the covering net is either a warp-knitted mesh or a weft-knitted mesh, and the mesh size of the covering net is between 10 and 100 meshes.

[0011] Beneficial effects

[0012] This invention provides a breathable material for backpacks. Compared with the prior art, it has the following advantages:

[0013] 1. In this utility model, by setting a breathable layer, the breathable material is sewn to the back of the backpack or shoulder straps, waist and other parts that come into close contact with the human body. When the user carries the backpack, the breathable layer is in direct contact with the human body, so that the heat and sweat vapor generated by the human body can be quickly diffused through the three-dimensional mesh structure of the breathable layer without penetrating any intermediate layer. On the one hand, the structure has good elasticity and resilience, and can form a stable and elastic buffer layer between the backpack and the back, which can evenly distribute the pressure of the backpack and avoid pressure on hard points. On the other hand, the structure can actively guide the air flow when under pressure, thereby reducing the accumulation of heat and moisture and increasing the breathability. Even under long-term heavy pressure, the internal air channels can remain unobstructed and stable, ensuring that the breathability will not decrease with the use time like traditional foam or fabric materials.

[0014] 2. In this utility model, by using the designed seam tape, the breathable material can be sewn onto any desired location on the backpack during production, such as the back support plate, shoulder strap pressure area, waist belt contact surface, etc. This concentrates the sewing stress on the sturdy seam tape, effectively avoiding direct damage to the core breathable layer structure from the seam, ensuring the firmness of the connection and the long-term stability of the breathability. After the breathable material is sewn onto any desired location on the backpack, the breathability effect can be better achieved, increasing carrying comfort. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides two technical solutions, specifically including the following embodiments:

[0023] Example 1:

[0024] A breathable material for backpacks includes a base material 1, which comprises a covering mesh 101, a breathable fabric 102, air pores 103, and a breathable layer 104. The breathable fabric 102 is pressed onto the outside of the breathable layer 104, and the covering mesh 101 is disposed on the outside of the breathable fabric 102, and the covering mesh 101 is connected to the outside of the breathable fabric 102 by sewing. The breathable layer 104 is a three-dimensional mesh structure made of one of the following materials: polyethylene elastomer, polypropylene elastomer, polyolefin elastomer, or thermoplastic polyester elastomer. This three-dimensional mesh structure has good ventilation and breathability characteristics. The three-dimensional mesh structure of the breathable layer 104 has multiple interconnected pores 3, and the pore diameter of the pores 3 is 0.1 mm to 5 mm.

[0025] When in use, the breathable material is sewn onto the back of the backpack or other areas in close contact with the human body, such as the shoulder straps and waist. When the user carries the backpack, the breathable layer 104 is in direct contact with the human body, allowing the heat and sweat vapor generated by the body to diffuse rapidly through the three-dimensional mesh structure of the breathable layer 104 without needing to penetrate any intermediate layer. On the one hand, this structure has good elasticity and resilience, forming a stable and elastic buffer layer between the backpack and the back, evenly distributing the pressure of the backpack and avoiding pressure from hard points. On the other hand, this structure can actively guide airflow when under pressure, thereby reducing the accumulation of heat and moisture and increasing the breathability. Even under long-term heavy pressure, the internal air channels can remain unobstructed and stable, ensuring that the breathability does not decrease with use like traditional foam or fabric materials.

[0026] Example 2:

[0027] Based on Embodiment 1, the outer surface of the breathable fabric 102 is provided with multiple air holes 103. The covering mesh 101 is either a warp-knitted mesh or a weft-knitted mesh, with a mesh size of 10 to 100 meshes. The outer edge of the material base layer 1 is provided with a seam tape 2. During the production of the backpack, the breathable material can be sewn to any desired location on the backpack, such as the back support plate, shoulder strap pressure area, or waist belt contact surface, through the seam tape 2. This concentrates the sewing stress on the sturdy seam tape 2, effectively avoiding direct damage to the core breathable layer 104 structure from the seam, ensuring the firmness of the connection and the long-term stability of the breathability. After the breathable material is sewn to any desired location on the backpack, the breathability effect can be better achieved, increasing carrying comfort.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
