Description

Technical Field

[0001] This utility model relates to the field of civil aviation passenger aircraft interior fabric technology, and in particular to a high flame-retardant civil aviation passenger aircraft interior fabric. Background Technology

[0002] With the rapid development of the air transport industry, the performance requirements for passenger aircraft interior materials are increasing. As an important component of civil aircraft, interior fabrics not only serve a decorative function but also need to meet stringent requirements for safety, comfort, and durability. Especially in the high-altitude flight environment, the performance of materials directly affects the safety and comfort experience of passengers.

[0003] Traditional interior fabrics for commercial airliners are typically made of ordinary fibers or composite materials. While these fabrics offer some decorative appeal, they exhibit significant drawbacks under high-intensity use and in complex environments:

[0004] Insufficient flame retardancy: Ordinary fabrics are easily flammable in high-temperature or open-flame environments, failing to meet the stringent flame retardancy standards of the international aviation industry, which may lead to the rapid spread of fire.

[0005] Limited antibacterial properties: As a high-density, enclosed space, the cabin is highly susceptible to the growth of bacteria and viruses. Traditional fabrics lack effective antibacterial properties and cannot meet the high standards of hygiene required.

[0006] Poor sound insulation: There are many noise sources inside and outside the aircraft cabin, such as engine noise and aerodynamic noise. Traditional interior fabrics are not good at noise reduction, which affects the passenger's riding experience.

[0007] Poor durability: With long-term use, traditional fabrics are prone to aging, tearing, or losing strength due to ultraviolet radiation, affecting their service life.

[0008] Lack of temperature control: The temperature in the cabin environment varies greatly, and ordinary fabrics are difficult to adapt to these changes, which may cause discomfort to passengers.

[0009] Therefore, it is essential to invent a highly flame-retardant interior fabric for civil aircraft. Utility Model Content

[0010] To address the aforementioned technical problems, this utility model provides a high flame-retardant civil aircraft interior fabric, solving the issues of insufficient flame-retardant performance, limited antibacterial properties, poor sound insulation, poor durability, and lack of temperature control in existing civil aircraft interior fabrics. The high flame-retardant civil aircraft interior fabric includes an antistatic outer layer, a core layer, an inner middle layer, a back support layer, and a protective edge seal. The core layer is sewn below the antistatic outer layer, and the inner middle layer is sewn below the core layer. The back support layer is sewn below the inner middle layer. The protective edge seal is sewn onto the outermost sides of the antistatic outer layer, core layer, inner middle layer, and back support layer.

[0011] The core layer includes a flame-retardant layer, an antibacterial layer, and a sound-insulating layer, with the antibacterial layer heat-sealed below the flame-retardant layer and the sound-insulating layer heat-sealed below the antibacterial layer; the core layer is sewn between the outermost antistatic layer and the middle inner layer.

[0012] The back support layer includes a support liner, a reinforced tear-resistant layer, a temperature-regulating layer, and a UV-protective layer. The support liner is sewn with yarn below the middle inner layer, and the reinforced tear-resistant layer is sewn with yarn below the support liner. The temperature-regulating layer is sewn with yarn below the reinforced tear-resistant layer, and the UV-protective layer is sewn with yarn below the temperature-regulating layer.

[0013] The flame-retardant layer inside the core layer is a fabric woven from highly flame-retardant polyester fiber yarn; the antibacterial layer is an antiviral fiber made by embedding antiviral silver into a polymer through chemical spinning, and then forming an antibacterial fabric through weaving; the sound insulation layer is a sound insulation material made by heating polyurethane foam to a certain temperature and then applying pressure to form it, and has the following functions: ① Flame retardant function: The flame-retardant layer of the core layer plays a role in inhibiting the spread of fire, which meets the strict flame retardant requirements of civil aviation for aviation materials. This helps to reduce the spread of flames in the event of a fire, improve safety, and the flame-retardant layer can quickly reduce the burning rate when it encounters a fire source, and even self-extinguish to a certain extent, preventing the fire from spreading in the cabin and ensuring passenger safety; ② Antibacterial function: The core layer... The antibacterial layer of the core layer effectively inhibits the growth of bacteria and viruses, ensuring the hygiene of the cabin environment and preventing bacterial growth and cross-infection. Especially in high-traffic public areas, the antibacterial layer provides long-term antibacterial effects through the embedding of silver ions or other antiviral components, effectively inhibiting the growth of common bacteria such as Escherichia coli and Staphylococcus aureus, thereby reducing the spread of diseases; ③ Sound insulation: The sound insulation layer of the core layer helps reduce the transmission of external noise and improve passenger comfort. The sound insulation layer is particularly important for long-haul flights, as it can reduce engine noise, cabin noise, etc., and improve the overall riding experience. This layer uses materials such as polyurethane foam, which can effectively absorb sound and vibration, reduce noise transmission, and create a quieter cabin environment.

[0014] The inner support layer of the back support layer is made of a non-woven fabric; the reinforced tear-resistant layer is made of an aramid fabric; the temperature-controlling layer is formed by embedding or encapsulating phase change materials inside the textile fabric using a phase change material embedding method; the UV-protective layer is formed by coating the textile fabric with a UV absorber to block UV rays, and has the following functions: ① Support function: The support lining provides basic support for the entire fabric, ensuring the stability and durability of the fabric, preventing damage when the fabric is deformed or under pressure, and providing a solid foundation so that the fabric maintains its shape during use, enhancing the overall structural integrity of the fabric; ② Enhanced tear resistance function: The reinforced tear-resistant layer enhances the tear resistance of the fabric, preventing the fabric from breaking under strong tension or external impact, and improving the durability of the fabric. ① **Strength and Durability:** By using high-strength materials such as aramid fabrics, the tensile and tear resistance of the fabric is enhanced, ensuring its stability under extreme conditions and extending its service life. ② **Temperature Control:** The temperature control layer helps regulate temperature, providing a comfortable environment and preventing excessively high or low temperatures, thus improving the passenger experience. By using phase change materials, the temperature control layer can absorb or release heat when the ambient temperature changes, regulating the fabric temperature and maintaining a suitable cabin temperature for increased comfort. ③ **UV Protection:** The UV protection layer blocks ultraviolet rays, protecting the underlying structure from UV damage. By coating with UV absorbers or adding UV-shielding materials, the UV protection layer effectively prevents UV rays from penetrating the fabric, protecting the structure, such as aircraft seats, from UV damage and extending the lifespan of the aircraft.
