Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a multi-layer composite non-woven fabric structure. Background Art

[0002] Non-woven fabrics, also known as nonwoven fabrics, are sheets, webs or pads made of oriented or randomly arranged fibers that are combined with each other through friction, cohesion or bonding, or a combination of these methods. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable.

[0003] The advantages of non-woven fabrics are light weight, softness, water repellency, breathability, non-toxicity, non-irritation, antibacterial, chemical resistance, antimicrobial and good physical properties, but their disadvantages are inferior strength and durability compared with textile fabrics; they cannot be washed like other fabrics; the fibers are arranged in a certain direction, so they are easy to split at right angles, resulting in poor shear resistance, so when non-woven fabrics are used to make outdoor dust-proof sunshade cloth, the tensile resistance is insufficient.

[0004] Therefore, it is necessary to provide a new multi-layer composite nonwoven fabric structure to solve the above technical problems. Utility Model Content

[0007] Preferably, a fire-resistant fiber layer is provided between the adhesive layer and the waterproof membrane layer.

[0008] Preferably, both sides of the refractory fiber layer are provided with a heat insulation coating.

[0009] Preferably, the mesh woven layer is a fiber woven layer.

[0010] Preferably, the mesh braided layer is a metal braided layer.

[0011] Preferably, a plurality of locking female buckles are embedded on one side of the intermediate composite layer, a connecting sub-buckle is installed on the locking female buckle, and the connecting sub-buckle is arranged on the other side of the intermediate composite layer.

[0013] 1. The present utility model provides a multi-layer composite non-woven fabric structure. The middle composite layer improves the tensile and shear resistance of the overall non-woven fabric by setting a mesh woven layer, a waterproof film layer and an adhesive layer to bond the fiber cloth layer;

[0014] 2. By setting a refractory fiber layer between the middle composite layer and the fiber cloth layer, and an insulating coating on the refractory fiber layer, the non-woven fabric has good fire and heat insulation properties, which is convenient for outdoor sunshade use. Locking female buttons and connecting male buttons are arranged on the non-woven fabric, making the connection of each layer of the non-woven fabric more firm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0019] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0020] Embodiment 1

[0021] Please refer to Figure 1 , a multi-layer composite non-woven fabric structure provided by an embodiment of the present utility model, the multi-layer composite non-woven fabric structure includes:

[0022] A middle composite layer 3, and fiber cloth layers 2 respectively arranged on both sides of the middle composite layer 3. The middle composite layer 3 includes a mesh woven layer 31. Waterproof film layers 32 are pressed on both sides of the mesh woven layer 31. An adhesive layer 33 is provided on the side of the waterproof film layer 32 facing away from the mesh woven layer 31. The adhesive layer 33 is bonded to the fiber cloth layer 2 through a dotting structure;

[0023] A refractory fiber layer 1 is provided between the bonding adhesive layer 33 and the waterproof membrane layer 32.

[0024] It should be noted that: the intermediate composite layer 3 is composed of a mesh woven layer 31, a waterproof membrane layer 32 and a bonding adhesive layer 33. Then, a fiber cloth layer 2 is arranged on the bonding adhesive layer 33. Such a multi-layer composite structure increases the tensile and shear resistance of the non-woven fabric structure, making it not easily broken during use. By adding the waterproof membrane layer 32, the overall waterproof performance is improved, facilitating sunshading and rain protection outdoors. The fiber cloth layer 2 is bonded to the intermediate composite layer 3 through the bonding adhesive layer 33 of the dispensing mechanism, which is convenient for bonding. Further, by adding the refractory fiber layer 1, the flame retardancy of the overall non-woven fabric is improved.

[0025] In an embodiment of the present invention, please refer to Figure 1 , heat insulation coatings 11 are provided on both sides of the refractory fiber layer 1;

[0026] It should be noted that: in this way, while the refractory fiber layer 1 improves the overall flame retardancy, heat insulation coatings 11 are brushed on both sides. Specifically, a foil heat insulation coating or a nano heat insulation coating can be coated. In this way, it has good heat insulation performance. When carrying out sunshading and shielding protection, it can insulate heat and effectively reduce the temperature inside the sunshade;

[0027] Furthermore, the mesh woven layer 31 is a fiber woven layer, so that the fiber woven layer is lighter in weight and is convenient for reducing the weight of the overall non-woven fabric; in order to obtain stronger shear resistance, the mesh woven layer 31 can be selected as a metal woven layer, such as a copper wire woven layer or a stainless steel woven layer.

[0028] Embodiment 2

[0029] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , a number of locking female buttons 4 are embedded on one side of the intermediate composite layer 3, a connecting male button 5 is installed on the locking female button 4, and the connecting male button 5 is arranged on the other side of the intermediate composite layer 3.

[0030] It should be noted that: after the refractory fiber layer 1 and the fiber cloth layer 2 are bonded to both sides of the intermediate composite layer 3, it is uniformly punched, and then the composite multi-layer structure is further pressed and fixed by using a number of locking female buttons 4 and connecting male buttons 5, so that the whole is more compact.

[0031] The working principle of the multi-layer composite non-woven fabric structure provided by the present invention is as follows:

[0032] The middle composite layer 3 is composed of a mesh woven layer 31, a waterproof film layer 32 and an adhesive layer 33. Then, a fiber cloth layer 2 is arranged on the adhesive layer 33. Such a multi-layer composite structure increases the tensile and shear resistance of the non-woven fabric structure, making it not easily broken during use. By adding the waterproof film layer 32, the overall waterproof property is improved, facilitating sunshading and rain shielding outdoors. The fiber cloth layer 2 is bonded to the middle composite layer 3 through the adhesive layer 33 of the dispensing mechanism, and the bonding is convenient. Further, by adding a refractory fiber layer 1, the flame retardancy of the overall non-woven fabric is improved. Further, while the refractory fiber layer 1 improves the overall flame retardancy, heat insulation coatings 11 are brushed on both sides. Specifically, a foil heat insulation coating or a nano heat insulation coating can be coated, so that it has good heat insulation performance. When performing sunshading and shielding protection, it can insulate heat and effectively reduce the temperature inside the sunshade;

[0033] Further, after the refractory fiber layer 1 and the fiber cloth layer 2 are bonded to both sides of the middle composite layer 3, it is evenly punched, and then several locking nuts 4 and connecting sub-buckles 5 are used to further press and fix such a composite multi-layer structure, making it more compact as a whole.
