Description

Technical Field

[0001] This invention relates to the field of wave-absorbing and noise-reducing materials technology, and in particular to a force-electric conversion noise-reducing functional fabric. Background Technology

[0002] With the accelerating pace of urbanization and the continuous improvement of living standards, people's demands for the comfort of their living and working environments are increasing. Among these demands, indoor environmental noise pollution has gradually become a prominent issue and a hot topic of public concern. While base fabrics such as cotton, linen, and silk play an important role in daily clothing and decoration, their noise reduction effect is poor, failing to effectively reduce the impact of environmental noise on people. Within the scope of existing noise control technologies, traditional noise reduction materials and methods are mostly based on sound absorption, sound insulation, or sound attenuation mechanisms, achieving noise reduction goals through the absorption, reflection, or dissipation of sound waves. However, with the rapid development of technology and the continuous improvement of noise control standards, these traditional methods have shown limitations in certain specific application scenarios, making it difficult to meet higher-level noise reduction needs. Moreover, traditional noise reduction materials and methods generally suffer from drawbacks such as limited noise reduction efficiency, heavy weight, and high cost.

[0003] Against this backdrop, this invention innovatively proposes a force-to-electricity conversion noise-reducing functional fabric. This technology cleverly combines a base fabric layer with a highly electronegative material, utilizing the effect of sound waves to generate Maxwell displacement current, efficiently converting the mechanical energy of sound wave vibrations into electrical energy, thereby achieving a significant noise reduction effect. This novel noise-reducing material not only possesses excellent noise reduction performance but also boasts numerous advantages such as lightweight, low cost, ease of processing, and wide applicability. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the noise reduction effect of the base fabric layer is poor, failing to effectively reduce the impact of environmental noise on people. This invention provides a force-to-electricity conversion noise-reducing functional fabric, belonging to the field of wave-absorbing noise reduction materials technology. This functional fabric consists of a highly electronegative material and a base fabric layer. The highly electronegative material is a material containing highly electronegative elements or groups. When sound waves contact the functional fabric, the highly electronegative material and the fabric are subjected to force, generating a Maxwell displacement current, converting the mechanical energy of the sound wave vibration into electrical energy, thus achieving noise reduction and providing a novel solution for improving the noisy environment.

[0005] The functional fabric consists of a base fabric layer and a highly electronegative material. The highly electronegative material is a material containing highly electronegative elements or groups. When a sound wave, as a mechanical wave, comes into contact with the functional fabric, the highly electronegative material and the fabric are subjected to force, generating a Maxwell displacement current, which can convert the mechanical energy of the sound wave vibration into electrical energy, thereby achieving the loss and reduction of sound energy and achieving the purpose of noise reduction.

[0006] The structure of the functional fabric includes a single-layer structure, a multi-layer structure, or a fiber interwoven structure.

[0007] The single-layer structure is formed by directly integrating a highly electronegative material into the base fabric layer to create a single-layer noise-reducing fabric.

[0008] The multilayer structure includes at least one layer of highly electronegative material and at least one base fabric layer, wherein the highly electronegative material layer and the base fabric layer are combined by coating, bonding, sewing or hot pressing.

[0009] The fiber interlacing structure is formed by interlacing highly electronegative material fibers with base fabric fibers to create a textile fabric with noise reduction function.

[0010] The highly electronegative material is distributed in the base fabric layer in the form of uniform dispersion, coating, or fiber, and the preparation method includes:

[0011] Solution mixing method: The highly electronegative material is uniformly dispersed in the polymer solution used to prepare the functional fabric, and then the composite fabric containing the highly electronegative material is obtained through spinning, weaving or molding processes.

[0012] Coating method: Strongly electronegative materials are made into a coatable form by solvent or melting, and then dipped, sprayed or scraped onto the surface of the fabric or penetrated into the interior of the fabric. After drying or curing, a force-electric conversion noise reduction coating functional fabric is formed.

[0013] Fiber textile method: The textile fabric containing the strong electronegative material is produced by blending or interweaving the fibers of the base fabric layer with the fibers of the strong electronegative material through the textile process.

[0014] The strongly electronegative materials include, but are not limited to, polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP).

[0015] The fabric includes, but is not limited to, natural fiber fabric, synthetic fiber fabric, or blended fabric.

[0016] The natural fibers include, but are not limited to, cotton, linen, silk, wool, cotton-linen blends, silkworm silk, rabbit hair, etc.

[0017] The synthetic fibers include, but are not limited to, polyester, nylon, polyacrylonitrile, polypropylene fiber, polyvinyl alcohol fiber, spandex, aramid, etc.

[0018] The highly electronegative material layer has excellent electronegativity and can generate Maxwell displacement current under the action of sound waves, which can efficiently convert sound wave vibration into electrical energy, thereby achieving the effect of sound energy loss and reduction. The amount of highly electronegative material added can be adjusted according to the required noise reduction effect.

[0019] The preparation method can further improve the noise reduction effect of the fabric by adding additives (such as dispersants, stabilizers, etc.), micro-nano processing (such as etching, imprinting, etc.), or adjusting process parameters (such as temperature, pressure, time, etc.) to meet the noise reduction needs of different application scenarios.

[0020] Beneficial technical effects of the present invention:

[0021] Compared with existing technologies, this invention utilizes a novel force-to-electricity conversion noise reduction technology, which can effectively improve the noise reduction function of the base fabric layer and has the following advantages:

[0022] 1. By cleverly incorporating highly electronegative materials into the fabric, the noise reduction performance of the base fabric layer is significantly improved.

[0023] 2. By adjusting the type and amount of highly electronegative materials, as well as the type and structure of the fabric, noise reduction needs in different application scenarios can be flexibly met.

[0024] 3. Traditional noise reduction materials often suffer from high costs and complex processing. In contrast, this preparation method is simple and easy to implement, and can be achieved through mixing the raw materials, coating, or fiber weaving.

[0025] This can be achieved in multiple ways, greatly reducing production costs. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 for illustrative purposes only and are not intended to limit the invention.

[0038] Conversely, this invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the invention as defined in the claims. Furthermore, to provide a better understanding of the invention, certain specific details are described in detail below. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0039] This invention provides a force-to-electricity conversion noise reduction functional fabric, belonging to the technical field of wave-absorbing noise reduction materials. The functional fabric consists of a base fabric layer and a highly electronegative material, which is a material containing highly electronegative elements or groups. When sound waves contact the functional fabric, the highly electronegative material and the fabric are subjected to force, generating a Maxwell displacement current, converting the mechanical energy of the sound wave vibration into electrical energy, thus achieving noise reduction.

[0040] Figure 1-9These are schematic diagrams of a force-to-electricity conversion noise-reducing fabric. The fabric comprises a base fabric layer and a highly electronegative material, including but not limited to polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP). The base fabric layer includes, but is not limited to, natural fiber fabrics, synthetic fiber fabrics, or blended fabrics. Natural fibers include, but are not limited to, cotton, linen, silk, wool, cotton-linen blends, silkworm silk, and rabbit hair. Synthetic fibers include, but are not limited to, polyester, nylon, polyacrylonitrile, polypropylene, polyvinyl alcohol, spandex, and aramid. The highly electronegative material layer and the fabric layer are bonded together by coating, bonding, sewing, or hot pressing. When sound waves contact the force-to-electricity conversion noise-reducing fabric, the highly electronegative material and the fabric are subjected to force, generating a Maxwell displacement current, converting the mechanical energy of the sound wave vibration into electrical energy, thus achieving noise reduction. Figure 10 This is a schematic diagram illustrating the principle of force-to-electricity conversion noise reduction functional fabric. The Maxwell displacement field current generating part of the force-to-electricity conversion noise reduction functional fabric 11, under the influence of sound waves, generates a Maxwell displacement current through the force exerted on the highly electronegative material and the fabric, efficiently converting sound wave vibrations into electrical energy, thereby achieving sound energy loss and reduction. The amount of highly electronegative material added is adjusted according to the desired noise reduction effect.

[0041] Adding a dispersant to the fabric treatment solution can effectively improve the uniformity of noise reduction material dispersion on the fiber surface, avoid agglomeration, and thus enhance the noise reduction effect.

[0042] To maintain the stability and durability of noise-reducing materials during long-term use, stabilizers can be added. Stabilizers can resist the effects of environmental factors (such as changes in light and humidity) on noise-reducing performance, extending the lifespan of the fabric.

[0043] You can also add antioxidants, fire retardants, antibacterial agents, etc., to give the fabric additional functional properties without affecting or further improving its noise reduction capabilities.

[0044] By using chemical or physical methods, precise etching is performed on the surface of functional fabrics at the microscale to create specific surface structures. These structures can more effectively absorb, scatter, or reflect sound waves, thereby improving noise reduction efficiency.

[0045] Functional fabrics are embossed using a mold to create tiny raised textures. This texture not only increases the fabric's surface area but also alters how sound waves interact with the fabric, helping to reduce sound reflection and propagation, thus achieving noise reduction.
