Overview of nonwoven materials
Non woven materials are a new type of material that directly mixes, forms, and reinforces fibers or particles without going through textile processes. Its materials can be synthetic fibers, natural fibers, metals, ceramics, etc., with characteristics such as waterproof, breathable, soft, and wear-resistant, gradually becoming the new favorite in various fields.
Application of non-woven materials in automotive acoustic components
Non woven materials composed of irregular fibers contain many narrow and connected pores. When the vibration of air particles caused by sound waves propagates through the pores, friction and viscous resistance are generated, which converts sound energy into heat energy and extracts it. Therefore, this type of material has excellent sound absorption performance, and many factors such as thickness, fiber diameter, fiber cross-section, and production process can affect this performance. Non woven materials are mainly used for engine hood lining, instrument panel, roof lining, door lining panel, trunk lid and lining panel and other parts, which can improve the NVH performance of automobiles
Non woven materials are widely used in automotive interiors, such as car seats, doors, interior panels, etc. This material not only has softness and breathability, but also provides excellent comfort, significantly improving the comfort of car seats. Meanwhile, due to the excellent wear resistance of non-woven materials, they can be used in friction prone areas such as car doors to enhance the durability of the car.
Application of filters
Car engines require an excellent air filter to ensure smooth engine operation. Traditional filter materials generally use paper materials, but their air permeability decreases after adsorbing dust and dirt, which may affect the normal use of the engine. And non-woven materials can effectively breathe and have excellent filtering effects, so non-woven materials have gradually become the preferred material for automotive filters.
Application of soundproof materials
During the process of driving a car, the engine emits significant noise, and some soundproofing materials are needed to reduce the noise. The flexibility and good sound absorption performance of non-woven materials make them one of the preferred materials for sound insulation. Meanwhile, non-woven materials can also be used in areas such as car windshields, effectively blocking the transmission of atmospheric noise.
Summary
Overall, the application prospects of non-woven materials in the automotive field are very broad. Non woven materials can be used to replace traditional materials in car interiors, filters, sound insulation materials, etc., to improve the quality and comfort of cars. Of course, it is also necessary to continuously enhance the mechanical strength, aging resistance, and other advantages of this material in order to better meet the needs of the automotive industry.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
