Description

Technical Field

[0001] This utility model relates to the field of polyester fabric technology, and in particular to an antistatic and light-blocking polyester fabric. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, the demand for functional textiles is increasing. Especially against the backdrop of the widespread use of electronic devices, frequent static electricity problems, and the increasing need for light environment control, it is particularly important to develop a fabric that has both antistatic properties and can effectively block light.

[0003] While traditional polyester fabrics excel in strength, abrasion resistance, and durability, they suffer from significant shortcomings in antistatic properties and light-blocking effects. For example, ordinary polyester fabrics are prone to accumulating static electricity, which not only affects the user experience but can also attract dust, shortening the fabric's lifespan. Furthermore, conventional light-blocking fabrics often achieve their effect by increasing thickness or employing multi-layered structures, but this reduces the fabric's breathability and softness, impacting comfort.

[0004] To overcome these problems, various attempts have emerged in the market, such as adding conductive fibers to the fabric to improve antistatic properties, or coating it with light-blocking materials to enhance its light-blocking effect. However, these methods typically only solve a single problem and often face challenges in practical applications, such as poor durability, complex processing, and high costs. In particular, how to achieve both efficient antistatic and light-blocking functions while ensuring the fabric is lightweight and soft is a key challenge.

[0005] In view of this, an antistatic and light-blocking polyester fabric is proposed to solve the above problems. Utility Model Content

[0018] This utility model provides an antistatic, light-blocking polyester fabric, which, compared with the prior art, has the following advantages:

[0019] 1. This invention significantly improves the antistatic properties of the fabric by embedding a conductive mesh layer within the base fabric layer and employing a double-layer composite structure design with upper and lower conductive meshes, combined with an insulating spacer layer and selectively conductive adhesive dots. Silver-plated polyester fibers and carbon fibers are arranged in the warp and weft directions respectively, forming a stable mesh-like conductive path that effectively collects and discharges static electricity, preventing its accumulation. Simultaneously, the conductive fiber surface is coated with an anti-oxidation protective layer, further enhancing the durability and environmental corrosion resistance of the conductive material. Furthermore, the conductive edge banding design not only achieves conductive connection at the edges but also prevents a decrease in conductivity due to edge wear, thereby improving the overall structural stability and service life.

[0020] 2. This utility model provides excellent light-blocking performance through a double-layer composite structure design of light-blocking composite layer, which combines light-blocking coating and uniformly dispersed light-blocking particles.

Detailed Implementation

[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please refer to Figures 1-7 This utility model provides an antistatic light-blocking polyester fabric, including a base fabric layer 1, which is woven from high-density twill polyester fibers, providing basic support and physical strength. The high-density weave structure increases the durability and stability of the fabric while maintaining a soft hand feel.

[0033] The conductive mesh layer 4, composed of conductive fibers interwoven into a mesh structure, is embedded in the base fabric layer 1, forming a highly efficient conductive network. This network can quickly and effectively disperse and release static electricity, preventing its accumulation from affecting the user experience. Furthermore, by embedding the conductive mesh into the base fabric layer 1, not only is the overall mechanical strength of the fabric enhanced, but the stability and durability of the conductive layer are also ensured, making it resistant to damage even with frequent use or harsh environments. In addition, this design allows the fabric to maintain a soft feel while possessing excellent antistatic properties, providing users with a more comfortable and safer user experience.

[0034] The conductive mesh layer 4 includes an upper conductive mesh 41 and a lower conductive mesh 42, with an insulating spacer layer 44 between them. The upper conductive mesh 41 and the lower conductive mesh 42 achieve selective conductivity at the mesh nodes through conductive adhesive dots 43. Due to its porous nature, the conductive adhesive dots 43 can pass through at specific locations, thus forming a stable mesh conductive path, effectively collecting and discharging static electricity, and preventing static accumulation. The two different conductive meshes not only provide complementary electrical performance, but also, by using conductive adhesive dots 43 for connection only at specific nodes, rather than connecting them completely, this design can reduce unnecessary material usage, lower costs, and reduce weight while ensuring conductivity efficiency.

[0035] The upper conductive mesh 41 is made of silver-plated polyester fibers arranged in the warp direction, and the lower conductive mesh 42 is made of carbon fibers arranged in the weft direction. The insulating spacer layer 44 is a porous polyester nonwoven fabric. The silver-plated polyester fibers and carbon fibers have good conductivity. By arranging these two materials in different directions, a three-dimensional conductive mesh structure can be formed to ensure that static electricity can be effectively conducted from one position of the fabric to another and finally discharged.

[0036] The conductive fiber surface of the conductive mesh layer 4 is covered with an anti-oxidation protective layer, which can effectively isolate oxygen and moisture in the air and prevent the conductive fiber from undergoing oxidation.

[0037] An adhesive layer 5 is provided between the base fabric layer 1 and the conductive mesh layer 4. The adhesive layer 5 can firmly bond the base fabric layer 1 and the conductive mesh layer 4 together to form an integral structure.

[0038] The light-shielding composite layer 3, located on one side of the conductive grid layer 4, adopts a double-layer composite structure and is composed of light-shielding materials. The light-shielding composite layer 3 includes a light-shielding coating 31 and light-shielding particles 32. The light-shielding particles 32 are uniformly dispersed in the light-shielding coating 31, which can ensure that the light-shielding composite layer 3 provides a consistent and efficient light-shielding effect on the entire material surface, avoiding light transmission points or shadow areas caused by uneven distribution of light-shielding materials, thereby ensuring the continuity and stability of use. At the same time, this uniform dispersion method helps to enhance the overall strength and durability of the coating, because the light-shielding particles 32 can play a certain reinforcing role in the coating, resisting the erosion and damage of the coating by the external environment and extending the service life.

[0039] The surface of the light-shielding coating 31 has a micro-protrusion structure 33. The micro-protrusion structure 33 can further enhance the light-shielding performance of the material. By increasing the path of light reflection and scattering, it can effectively reduce the chance of direct light transmission and provide a more thorough light-shielding effect.

[0040] One side of the light-shielding composite layer 3 is provided with anti-slip stripes 6. The anti-slip stripes 6 significantly enhance the anti-slip performance of the material, ensuring that the material can be firmly held in the predetermined position during use, reducing functional failure or inconvenience caused by slippage.

[0041] The fabric consists of a base fabric layer 1, a conductive mesh layer 4, and a light-blocking composite layer 3. The edges of the fabric are provided with conductive binding strips 2, which are electrically connected to the conductive mesh layer 4. This design ensures that the static electricity accumulated inside the fabric is quickly and effectively conducted to the conductive binding strips 2 through the conductive mesh layer 4 and safely released from there into the external environment, effectively preventing inconvenience or harm to the user caused by static electricity, such as electric shock or dust attraction.

[0042] In summary, the working principle of the antistatic and light-blocking polyester fabric of this utility model embodiment is as follows: a base fabric layer 1 is woven from high-density twill polyester fibers, and an adhesive layer 5 is set on it. Then, a conductive mesh layer 4 containing an upper conductive mesh 41 and a lower conductive mesh 42 is selectively connected to the adhesive layer 5 through an insulating spacer layer 44 and conductive adhesive dots 43. Then, a light-blocking composite layer 3 containing a light-blocking coating 31 and light-blocking particles 32 is added to one side of the conductive mesh layer 4, and micro-protrusions 33 and anti-slip stripes 6 are provided. Finally, a conductive binding strip 2 electrically connected to the conductive mesh layer 4 is added around the fabric to achieve effective release of static electricity.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
