Application Of Automotive Nonwovens

From cockpit filters and seat covers to trunk linings, acoustic blankets and carpet fabrics, nonwovens play an important role in the automotive market. In China, according to the current annual output of 700,000 cars, the demand for non-woven acoustic felts will reach 2.45 million square meters per year. In the 2000-2005 China Textile Industry Science and Technology Progress Project Guide, there are 15 projects related to the nonwoven fabric and industrial fabrics industry. The research content of “Inner Interior Materials Research and Product Development” includes Knitted fabric interior material, fireproof, antistatic car woven decorative velvet material, structural interior decorative fiber based laminate. The goal is to replace the import, to match the decorative fabric of the car, meet the requirements of luxury, comfort and safety, and its fireproof performance and antistatic performance have reached the domestic leading level.

Application status of non-woven fabrics in automobiles

It has been used in automotive parts since more than 40 years ago. Non-woven fabrics can be used for sound insulation, air filtration, heat insulation, reinforcement and the comfort and reliability of passengers. In addition to these advantages, non-woven fabrics are considered economical materials by many automobile companies because of their high strength and durability. As the use of non-woven fabrics in automobiles continues to grow, competition among coil producers participating in this market is also intensifying, and research and development work in this area is also intensifying.

Klaus Troeger, Sales Manager of Schwarzenbach/Saale, Automotive Division, Sandler, Germany, said, “In recent years, the requirements of automakers have promoted the development of specialty nonwovens.” “These products are constantly improving and improving. Newly developed processes and materials. For the industrial non-woven fabrics, the roads that have traditionally been occupied by fabrics have been paved the way." Consumers' requirements for automotive nonwovens are mainly low-cost, highly efficient filtration and sound absorbing materials.

As new automotive nonwovens continue to be introduced, automakers are investigating the use of these products to replace more expensive materials such as leather seats. Often not noticed by the driver or passenger, the non-woven fabric is hidden under the seat or carpet, or sewn together with other fabrics to improve strength and durability. Mr. Edward Merchlinsky, general manager of acupuncture fabric supplier Amoco Fabrics and Fibers Industrial Fabrics Branch, believes that acupuncture fabrics are particularly suitable for replacing leather seats because they are more economical and easy to handle during handling, sticking and sewing. Suitable for sewing.

Non-woven fabrics become stronger

The environmentally friendly nature of the nonwovens allows them to be used in cars instead of foam products. According to Mr. Dan Kamat, vice president of Precision Custom Coatings, automakers are increasingly aware of the environmental advantages of nonwovens compared to other materials. This can be seen in the growth of PCC needle-punched and thermally bonded nonwovens, which are used in hood linings, roof sheds, instrument panels and other small sound-insulating and insulating interior trims. more.

Automakers hope to stop using non-recyclable foams, and nonwovens manufacturers have developed materials that can replace foam and can be recycled. Others are also particularly strongly bonded to fiberglass and recycled materials, providing uniform color, no wrinkles and tears when stretched.

Eswegee's bonded nonwovens are produced by hot melt lamination and can be effectively used to replace the more traditional flame bonded woven-foam sandwich materials and are fully recyclable. The company's Multiknit and Kunit nonwovens from the Techtex stitching line in Mittweida can replace foams up to 8mm thick.

Eswegee Vliesstoffe, a company that specializes in the production of chemically bonded, mechanically consolidated and thermally bonded nonwovens for automobiles, also feels the tendency of non-woven fabrics to replace fabrics. New stitching products have been developed for automotive interior trims, such as Roof or glove box. Other environmentally friendly stitchbonded fabrics have also been developed to replace the foam in the fit material for the seat.

The laminate can utilize a combination of glass fibers, carbon fibers, and aromatic fibers, as well as the above fibers, to produce a multiaxial nonwoven fabric having a weight of from 200 to 2,800 per square meter.

Finishing nonwovens give cars a lot of advantages and quickly replaces traditional fabrics, but the needs of car manufacturers and consumers have fundamentally determined the style and size of the most popular cars. Naturally, the number and variety of cars sold in a year will have a major impact on nonwovens producers. Mr. Merchlinsky of Amoco believes that the trend of car style, size and material usage can be changed very quickly, and the time period can be measured in months.

If any car manufacturer likes a bucket seat. This demand will spread rapidly in the automotive industry chain, making the participation competition in this market particularly fierce, so manufacturers must be able to respond to this change anytime, anywhere, and provide the right products.
