Non-woven fabric material for automobile interior decor […]

Non-woven fabric material for automobile interior decoration
The automobile manufacturing industry, especially the car manufacturing industry, is an important indicator to measure the level of industrial development of a country, and it directly reflects the degree of development of a country. According to the development plan of China's automobile industry, in the first 10 years of entering the new century, while continuously increasing the output and quality of cars, we will focus on the development and production of household practical energy-saving cars suitable for our country's characteristics, so that cars will gradually enter thousands of families. Ten thousand households, and the development of non-woven products necessary for automobile matching will surely accomplish a lot. Nonwovens have a wide range of raw materials, short process flow, low cost, and good applicability. The application of nonwovens in the automotive industry is bound to grow more rapidly.


Automotive interior materials-pad materials
The cushion material is a kind of material that has the functions of vibration reduction, sound insulation, heat insulation, sealing, and gap filling. It has a great influence on the comfort of the car. The front baffle, control panel, and instrument panel are the parts where the vibration, noise, and heat generated by the engine are transmitted into the cab, and the bottom plate is the part where the vibration and noise caused by the road conditions when the car is driving, and add them to these parts The cushion material can effectively receive the effects of vibration reduction, noise reduction and heat insulation. The sealing materials used in automobiles are almost all non-woven products, including needle punched non-woven fabrics, pad non-woven fabrics and composite non-woven fabrics. There are also gap-filling materials, the most typical of which is car seat cushions. The use of needle punched or hot-bonded non-woven fabric laminated structure instead of polyurethane foam can greatly improve the micro-climate of the seat and improve the ride comfort.


Automotive interior materials-covering materials
When the non-woven covering material is used as the back cover, it can take advantage of its light weight and low price. For example, the back of the Santana car roof and seat cover are covered with a thin non-woven fabric. The front cover is the interior decoration textile. Due to its excellent extensibility, the non-woven fabric is suitable for the molding of car roofs, and has a good appearance, greatly reduced costs, and is very competitive. Car roof materials are the most used textiles in the automobile industry. In the past, nylon knitted pile fabrics were mainly used, but now they have been partially replaced by needle punched nonwovens. Specifically, different non-woven fabric production processes should be used to produce non-woven fabric products according to different vehicle models and standard requirements. Generally speaking, there are three main types of non-woven fabrics for car roofs. One is needle-punched non-woven fabrics that have undergone a needle-punching process, and the other two non-wovens are 65 g/m² polyester hot-rolled non-woven fabrics and specifications. It is a 25 g/m2 filament polypropylene non-woven fabric. The processing process is to compound the above-mentioned three kinds of non-woven fabrics with the main material of the roof, and then press and form them, directly supporting the OEM. According to the survey, a typical car requires about 4.3 square meters for each ceiling, and about 7.28 square meters for a station wagon. Based on the current number of cars and station wagons produced nationwide, the annual demand for non-woven fabrics after the needle punching process is finalized reaches 2.1 million square meters. At present, 50% of European cars use non-woven fabrics for roof interior fabrics; Japan uses non-woven fabrics for roof decorations also close to 50%; North American car roof decorations have gradually accepted non-woven fabrics since the 1990s. 


Automotive interior materials-filter materials
Non-woven fabric filter materials are the fastest growing field in the non-woven fabric industry, and the development of non-woven fabric filter materials in the automotive industry is also quite rapid. According to incomplete statistics, non-woven filter materials for the automotive industry account for 3.8% of the total non-woven fabric output in the market. There are all kinds of ultra-fine particles harmful to the human body inside the car compartment, and the use of non-woven fabric filters can effectively eliminate these harmful particles. Nowadays, non-woven fabric air filters are commonly used in European car trunks, and Japan also regards non-woven fabric filters as a necessary device for cars. The 3M company in the United States, the Nipadisso company in Japan and the Weco company specialize in the production of non-woven filter materials for General Motors, Toyota Motor Corporation and Matzda, Bell and Fiat cars, and continue to develop and research, and launch new products. . 3M Company and Kuraray Chemical Company of Japan recently jointly developed a new type of air filter for automobiles. It uses two layers of polypropylene non-woven fabric with an activated carbon sheet structure in between, and uses a variety of heavy metal catalysts to fix in the activated carbon. The surface of the microporous diameter can absorb all kinds of harmful chemicals. This new filter has an effective life of more than one year compared with other purification materials at comparable prices. In addition to purifying the air in the car, non-woven fabric filters are also used in other parts of automobiles and in the production process of automobiles, such as automobile engine filters, air-conditioning hot-melt non-woven fabric filters, automobile exhaust emission needle-punched felts or melt-blown non-woven fabrics. Woven cloth filter material, composite non-woven cloth filter bag for electrophoretic paint production line, etc.
