Green car interior also gives you a quiet space

Since the reform and opening up, China’s automobile production has increased at an average annual rate of 35% to 50%. In recent years, there has been a well-developed momentum of blowout. The rapid development of the automotive industry has greatly promoted the improvement of the production technology of automotive interior materials. Automotive interior materials include gasket materials, cover materials, and filter materials. The requirements for automotive interior materials are mostly appearance requirements and functional characteristics. The requirements in terms of appearance characteristics are that the engineering design and the design of the process can be performed; the requirements in terms of functional properties are cutability, formability, lightweight, reinforcement, vibration isolation, heat resistance, sound insulation , sound absorption, heat insulation, cushioning, elastic recovery, flexibility, flame retardancy, and weldability.

Automotive interior materials can be made from traditional textiles, plastics and nonwovens. Because non-woven fabrics are cost-effective, functional, and light in weight, they help reduce the amount of fuel in vehicles. In 1997, the amount of non-woven fabric for a car was only lm2, and it has now reached 20 m2 (amount of 15-20 kg), and the usage has continued to increase.

As people pay more and more attention to environmental protection, many scholars and companies have begun to devote themselves to the development of new car interior sound-absorbing and heat-insulating materials. Various countries have studied non-woven fabrics so that they can be used in the sound absorption and noise reduction process of automobiles. Play a bigger role. Middle-to-high-end vehicle manufacturers look more at the use of re-engineered and efficient materials. For example, U.S. General Corporation added low-melting point polyester fiber to a polyester fiber mesh of 0.44 to 0.666 tex, and the needle-punched reinforced material has the characteristics of low cost, light weight, and recyclability. Japan Nissan Co., Ltd. mixes irregular-shaped cross-section fibers with a linear density of less than 0.555 tex in the raw fiber, and produces a non-woven fabric through thermal adhesion, which has a good sound-absorbing effect and can be used as a vehicle interior cushion material. Switzerland EMS-CHE. MIE uses 70% special polyester staple fiber and low-shrinkage regenerated fiber to form a net. After needle punching to form a high loft material, the compounded and molded material has a suitable stiffness, which is suitable for a car bottom carpet. German Wcrke company uses flax fiber mixed with polypropylene fiber. After being consolidated by acupuncture, the molded material has excellent stiffness, tensile strength and sound-absorbing effect, and is low in price. It is suitable for door panel liners, cushions and luggage compartments. lining.

Zhejiang Qianfeng Auto Parts Co., Ltd. is a high-tech industrial company that was newly developed in the eleventh century and is committed to the research and development and production of sound-absorbing insulation materials for new environmentally-friendly car interiors. Specializing in the production of automotive sound-absorbing cotton, car noise insulation cotton, car interior sound-absorbing insulation cotton, single / two-component sound-absorbing cotton, polyester fiber sound-absorbing cotton, new environmental sound-absorbing cotton, sound-absorbing insulation materials, the company passed the ISO/TS16949 and CCC certification, production of two-component automotive acoustic insulation cotton noise absorption, temperature and flame retardant, lightweight environmental protection, waterproof moisture, soft, fluffy, oil and other fine features, are widely used in aerospace, light rail, motor vehicles, cars Internal and external ornaments, military supplies (military jackets, quilts, etc.), shoes (climbing shoes), winter clothes, warm gloves, masks, composite fabrics, health care, home, KTV entertainment, mechanical equipment, and electronic household appliances.

Products are tested and certified by a number of third-party testing agencies in China, and can be punched and cut into various shapes of sound-absorbing mats, heat-insulating mats or compression molding according to customer requirements. The production of two-component automotive sound-absorbing cotton products of various technical indicators and parameters are in the same industry-leading level!
