The annual production of automobiles in our country has gradually increased, and the problem of pollution in automobiles has become more and more serious. The first is the pollution caused by the car itself. The plastic parts, carpets, roof mats, and seats installed in the car will not directly meet the international environmental protection standards and will directly cause air pollution in the car. Secondly, the problem of interior pollution caused by car interior parts is very complicated and lacks the major problem of standard control. Inside the car, especially in cars, leather, sponges, floor glue, floor mats, adhesives, leather seats, door trim fabrics, plastic dashboards, ground plastic panels, brake vane rubber panels, and plastic pipes that contain harmful substances Phenolic aldehydes, which produce harmful gases, release benzene, formaldehyde, acetone, xylene, and other harmful gases to stimulate the smell of the nose at all times, posing a potential threat to the health of the crew.

Pay more attention to the development direction of future automotive interior decoration materials, and develop more and better automotive non-woven materials are one of the development directions of China's automotive interior components. The directions include: Pursuing convenience, economicality, comfort, and diversification in accordance with changes in lifestyle, developing non-woven materials with deep moldability, light weight, and thinness; meeting the needs of environmental protection. Save energy, resources, and "green" interior materials with recycled use characteristics, develop single material nonwoven interior materials; develop lightweight, more sound-absorbing, sound-insulating properties, anti-staining, antibacterial, deodorizing, aromatic , Functional non-woven interior materials with negative ion properties; Development of eco-friendly high-performance battery separator materials for electric vehicles.

A noteworthy trend in the research and development of foreign automotive interior materials is the emphasis on the use of hemp natural fibers in automotive interior structural materials (such as roofs, door trims and rear hatch covers).

In 2001, the number of hemp fibers used in the European automotive industry accounted for 17%. Since 1996, its number has grown at a very high rate of growth and has grown by 90% for the period 1999-2000. Thermoplastic or thermoset moldability using natural fibers (such as door panels, etc.) has become the standard configuration of European cars. The natural fiber used in each car is 5-10 kilograms, as a new processing technology - hemp natural fiber + Polypropylene injection molding technology will continue to grow in the coming years. The increase in the use of hemp natural fibers in automotive molded interior trims is due to the fact that it provides ecologically and impact-resistant, more resilient structural parts.

The objective of the QINETIG-LEG non-woven automotive research project in the United Kingdom, attended by Ford Motor Co., USA, is to develop natural fiber thermoplastic nonwoven composite technology for injection molding of interior parts to reduce the unsustainable raw materials of the automotive industry. Dependency.

According to EC regulations, by 2015 vehicles must be made of 95% recyclable materials. Natural fiber is a raw material that can be reborn, its products are easier to recycle, use less energy, and have lower costs. FORD believes that natural fiber is a material that absorbs energy better than synthetic fiber. It can make a tougher plate that is not easily broken by impact and is therefore safer. In addition, the use of natural fiber composite materials also helps to reduce vehicle weight and improve vehicle fuel economy.

With the maturation and development of the automobile industry and the maturity and progress of the concept of automobile consumption, the operation of the Chinese automobile industry is characterized by an increase in the number of vehicle types, elevation of interior trim pieces, rationalization of prices, and increasingly diversified positioning. At the same time, fierce market competition based on the above characteristics gave birth to the good business opportunities of the hemp car interior products.
