Description

Technical Field

[0001] This utility model relates to the field of home decoration technology, specifically to a waterproof and sun-proof outdoor sofa fabric. Background Technology

[0002] Outdoor sofa fabric is a component of protective furniture that needs to be exposed to sun and rain for extended periods. Traditional products often use coatings or lamination structures to achieve waterproofing, but these methods have the following drawbacks: First, ordinary laminated structures lack a drainage mechanism, and surface water can easily seep into the base layer, causing mold growth. Secondly, common multi-layered composite fabrics are bonded together with adhesives, which can easily peel off after long-term use. At the same time, insufficient breathability causes internal moisture to accumulate, affecting comfort. Third, edge treatment often uses simple stitching, which does not form an effective seal, allowing moisture to easily penetrate from the edges. Although some existing technologies use multi-layer composite structures, the layers are often fixed by full bonding, which improves waterproofness but sacrifices breathability and drainage. In view of the shortcomings of existing technologies, this utility model provides a waterproof and sun-proof outdoor sofa fabric to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a waterproof and sun-proof outdoor sofa fabric. The surface layer effectively reflects ultraviolet rays and blocks liquid penetration, extending its service life. The middle drainage layer allows accumulated water to be quickly guided to the drainage edge for discharge, while maintaining breathable space between layers. The waterproof and breathable bottom layer prevents stuffiness and dampness. The waterproof edging and drainage edge ensure both edge sealing integrity and maintain the external connectivity of the drainage channel. The overall structure achieves a firm bond between layers through a hot-pressing composite process, solving the problems of easy delamination, poor drainage, and poor breathability in traditional products.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof and sun-proof outdoor sofa fabric, comprising a top layer, a middle diversion layer and a waterproof and breathable bottom layer, which are stacked sequentially from top to bottom and fixedly connected by a hot-pressing composite process; The surface layer is a high-density Oxford cloth substrate and an anti-ultraviolet and water-repellent composite coating on its outer surface; The intermediate drainage layer is a 3D mesh fabric with a thickness of 3mm. The upper and lower surfaces of the intermediate drainage layer are connected to the surface layer and the waterproof and breathable bottom layer respectively through arrayed hot-press welding points to form a three-dimensional drainage and air guiding channel. The waterproof and breathable bottom layer is a thermoplastic polyurethane (TPU) breathable membrane; The sofa cover has a waterproof edging that covers the three-layer structure, and at least one side of the edging has a drainage edge that connects the three-dimensional drainage and air guiding channel of the middle guide layer to the outside.

[0005] Preferably, the hot-pressed weld points formed by the hot-pressed composite process are in a uniformly distributed rectangular array.

[0006] Preferably, the radius of the hot-pressed weld point is 1mm to 2mm, and the center distance between adjacent weld points is 5mm to 15mm.

[0007] Preferably, the waterproof edging is formed by wrapping and sealing the edge of the sofa fabric with polyurethane waterproof strips through a hot-pressing process.

[0008] Preferably, the drainage edge portion is formed by having a groove inside the edging during the hot pressing process, and the pressure at the position of the groove is controlled by a limiting mold, so that the edging does not completely flatten the channel of the middle guide layer.

[0009] Preferably, the UV-resistant and water-repellent composite coating is a polyvinyl chloride (PVC) coating doped with ceramic microspheres.

[0010] Preferably, the fabric of the sofa is also sewn with waterproof storage bags for placing items.

[0011] Preferably, the waterproof storage bag has a waterproof zipper at the opening.

[0012] Preferably, elastic fastening straps are fixedly provided at the four corners of the back of the sofa fabric, and the ends of the elastic fastening straps are provided with plastic fasteners so that the sofa fabric can be detachably connected.

[0013] Preferably, the thickness of the TPU breathable membrane is 0.01 mm to 0.05 mm.

[0014] The technical effects and advantages of this utility model are as follows: This waterproof and sun-protective outdoor sofa fabric combines a high-density Oxford cloth base layer with a UV-resistant and water-repellent composite coating, effectively reflecting ultraviolet rays and blocking liquid penetration, thus extending its service life. The 3D mesh fabric in the middle drainage layer, along with the array of hot-pressed welded points, forms a three-dimensional channel that allows accumulated water to be quickly guided to the drainage edge for discharge, while maintaining breathable space between layers. The TPU breathable membrane in the waterproof and breathable bottom layer blocks liquid water while allowing water vapor to escape, preventing stuffiness and dampness. The coordinated design of the waterproof edging and drainage edge ensures both the integrity of the edge seal and the external connectivity of the drainage channel. The overall structure achieves a firm bond between layers through a hot-pressed composite process, solving the problems of easy delamination, poor drainage, and poor breathability in traditional products.

[0018] 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.

[0019] This embodiment discloses a waterproof and sun-protective outdoor sofa fabric, according to the attached... Figure 1 To be continued Figure 2 As shown, the fabric includes a top layer 1, a middle drainage layer 2, and a waterproof and breathable bottom layer 3, which are stacked sequentially from top to bottom and fixedly connected by a hot-pressing composite process. The top layer 1 is a high-density Oxford cloth substrate with an anti-UV and water-repellent composite coating on its outer surface. The middle drainage layer 2 is a 3D mesh fabric with a thickness of 3mm. The upper and lower surfaces of the middle drainage layer 2 are connected to the top layer 1 and the waterproof and breathable bottom layer 3 respectively through arrayed hot-pressing welding points 6, forming a three-dimensional drainage and air-guiding channel. The waterproof and breathable bottom layer 3 is a thermoplastic polyurethane (TPU) breathable membrane. The perimeter of the sofa fabric is provided with a waterproof edging 4 that covers the three-layer structure, and at least one side of the edging 4 has a drainage edge portion 5 formed on its inner side, which connects the three-dimensional drainage and air-guiding channel of the middle drainage layer 2 with the outside.

[0020] According to the appendix Figure 1As shown, the hot-pressed weld points 6 formed by the hot-pressing composite process are arranged in a uniformly distributed rectangular array. The radius of the hot-pressed weld points 6 is 1mm to 2mm, and the center distance between adjacent weld points is 5mm to 15mm. Through this array design, the hot-pressed weld points 6 ensure a firm connection of the three-layer structure while preventing the intermediate flow-guiding layer 2 from being excessively compressed, thus maintaining the unobstructed flow of the three-dimensional drainage and air-guiding channels. Furthermore, the size and spacing of the hot-pressed weld points 6 have been optimized to ensure that the sofa fabric can maintain its flow-guiding function when subjected to external pressure, while improving overall durability and comfort.

[0021] According to the appendix Figure 1 As shown, the waterproof edging 4 is formed by wrapping and sealing the edge of the sofa fabric with polyurethane waterproof strips through a hot-pressing process. This edging 4 not only provides a waterproof seal at the edge but also enhances the overall structural strength of the sofa fabric. Furthermore, during the hot-pressing process of the edging 4, pressure is controlled by internal grooves and a limiting mold, preventing the edging 4 from completely flattening the channels of the intermediate drainage layer 2, thus forming a drainage edge 5. The drainage edge 5 allows moisture and air within the intermediate drainage layer 2 to exchange with the outside, achieving rapid drainage and breathability, and preventing moisture accumulation.

[0022] The UV-resistant and water-repellent composite coating is a polyvinyl chloride (PVC) coating incorporating ceramic microspheres. This coating effectively blocks ultraviolet rays through the reflection and scattering effects of the ceramic microspheres, while the PVC coating provides excellent water-repellent properties, giving surface layer 1 waterproof and sun-protective functions. Furthermore, this composite coating also improves the fabric's abrasion resistance and anti-aging properties, making it suitable for harsh outdoor environments.

[0023] According to the appendix Figure 2 As shown, a waterproof storage bag 7 for placing items is sewn onto the edging 4 of the sofa fabric. The opening of the waterproof storage bag 7 is equipped with a waterproof zipper 8 to ensure the bag's airtightness and prevent moisture from entering. Furthermore, the outer layer of the waterproof storage bag 7 uses the same high-density Oxford cloth substrate as the outer layer 1, while the inner layer uses a waterproof material, ensuring overall consistency and durability.

[0024] According to the appendix Figure 2 As shown, elastic fastening straps 9 are fixedly installed at the four corners of the back of the sofa fabric. The ends of the elastic fastening straps 9 are equipped with plastic fasteners 10 to allow the sofa fabric to be detachably connected. The elastic fastening straps 9 are made of rubber or elastic fiber material and have good tensile strength. The plastic fasteners 10 are quick-release designs, which make it easy for users to fix the sofa fabric to outdoor furniture and prevent it from shifting.

[0025] According to the appendix Figure 1 As shown, the thickness of the TPU breathable membrane ranges from 0.01 mm to 0.05 mm. This thickness range ensures that the waterproof and breathable base layer 3 has both sufficient mechanical strength and maintains high breathability, allowing water vapor to escape from the interior while preventing liquid water from penetrating.

[0026] Specifically disclosed, according to the appendix Figure 1 To be continued Figure 2 As shown, the 3D mesh fabric of the intermediate flow guiding layer 2 is made of polyester or polypropylene material, with a rhomboid or hexagonal mesh structure, providing stable support and flow guiding space. The rectangular array layout of the hot-pressed weld points 6 optimizes stress distribution and reduces localized wear. The drainage edge 5 is located on one or both sides of the sofa fabric, designed according to usage requirements, ensuring that the flow guiding channel is connected to the external environment.

[0027] Specifically disclosed, according to the appendix Figure 2 As shown, the waterproof storage bag 7 and the elastic fixing strap 9 are both connected to the edging 4 by high-frequency welding or sewing, ensuring the connection is strong and waterproof. The waterproof zipper 8 is made of plastic or metal and has a waterproof coating on the surface, making it smooth to operate and durable.

[0028] It needs to be emphasized that, according to the appendix Figure 1 To be continued Figure 2 As shown, the hot-pressing composite process is carried out under specific temperature and pressure conditions, for example, the temperature is set to 150°C to 200°C and the pressure is set to 0.5MPa to 1.0MPa, so that the surface layer 1, the intermediate guide layer 2 and the waterproof and breathable bottom layer 3 are fused together at the hot-pressing weld point 6 to form an integrated structure, ensuring the product's flexibility and lightweight.

[0029] It needs to be emphasized that, according to the appendix Figure 1 To be continued Figure 2 As shown, the formation of the drainage edge 5 relies on the precise control of the limiting mold. The groove size of the mold matches the mesh of the middle guide layer 2, ensuring that some channel openings are retained during the edge binding process 4. This design allows the sofa fabric to quickly drain surface water and stay dry in rainy weather, while the breathable bottom layer 3 allows internal moisture to escape, improving comfort.

[0030] Example 1: This example uses an outdoor sofa as an example, combined with the attached... Figure 1 To be continued Figure 2 Detailed explanation of the workflow: The workflow is as follows: When the sofa cover is laid on an outdoor sofa, the UV-resistant and water-repellent composite coating of the surface layer 1 reflects sunlight, preventing UV damage and moisture penetration. If it rains, the water flows off the surface layer 1, and a small amount of water that seeps in flows to the drainage edge 5 through the three-dimensional drainage and air-guiding channels of the middle guide layer 2 and is discharged. At the same time, the moisture generated by the human body escapes from the TPU membrane of the waterproof and breathable bottom layer 3, avoiding stuffiness. The elastic fixing strap 9 securely fixes the sofa cover with plastic buckles 10 to prevent it from shifting in the wind. The waterproof storage bag 7 is used to store small items and is sealed with a waterproof zipper 8 to ensure that the items are dry.

[0031] Example 2: This example uses cleaning and maintenance as an example, combined with the attached... Figure 1 To be continued Figure 2 Detailed explanation of the workflow: The workflow is as follows: When the sofa fabric needs cleaning, the user can unfasten the plastic fastener 10 and remove the sofa fabric; rinse the surface layer 1 with clean water, and the water will flow out quickly from the drainage edge 5 through the drainage channel of the middle guide layer 2 to avoid water accumulation; after wiping, the sofa fabric can be hung to dry, and the TPU breathable bottom layer 3 allows air circulation to accelerate drying; the waterproof edging 4 and the hot-pressed welding points 6 ensure that there is no delamination or deformation during the cleaning process; after long-term use, the anti-ultraviolet coating still maintains its performance and extends its service life.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
